5. TycoonWon RV Thermostat

If you are looking for a duo therm RV thermostat replacement, something that does not cost as much yet works the same, then this product might cater to your needs. It looks identical to the Dometic, but with different branding. You will notice that even the controls are quite the same. If you need to replace your thermostat but can’t find the exact one, this unit will do fine.

I like how easy and effortless it is to install this unit. You don’t need to have any experience with electronics at all. The package comes with a simple to understand, color-coded, instruction manual. If you follow the directions as shown exactly, you will not get lost in the process.

More importantly, it is also simple to use. There are only a couple of switches that you need to flip. It also features just one temperature setting slider. The slider has a Celsius scale on the left and Fahrenheit scale on the right, so you do not need to use a calculator when figuring out where to set the temperature slide.

You can even control the fan of the HVAC system from this thermostat. In detail, the fan can be set to turn on automatically when the furnace or the A/C starts up. Alternatively, users can set it to be on constantly, and at high or low speed.

• User-friendly product with switches and a slider temperature setting
• Installs effortlessly to fit well on any Dometic thermostat housing
• Capable of controlling both the furnace and air conditioner
• Can control the auxiliary fans of the HVAC system
• Hard to set the temperature to an exact value

6. Coleman 8330-3862 Digital Thermostat

The Coleman 8330-3862 Digital RV thermostat is the one that you need to get if you want the reliability and durability of a high-quality analog thermostat. Best of all, the device allows you to set the temperature to an exact value of your liking. You are getting an RV thermostat upgrade from the usual analog model.

One reason why many people like using digital thermostats is that they can set the temperature of their homes to an efficient level. Many people say that setting the thermostat to 25 degrees C (77-78 degrees F) and getting that exact value on a digital thermostat is no problem at all. It is not like a slider where you need to do a bit of guesswork.

Even though this heat cool analog thermostat is digital, you still install it as if it were an analog thermostat, so the wirings will not be difficult at all. The device requires no wiring to its LCD screen, and it runs on two AA batteries. Hence, you just need to connect this thermostat like you would with any analog mechanical type.

You can switch between the A/C and the furnace with just a flick of a switch, eliminating the need for separate controllers. This thermostat also allows you to control the fans. You can set it for the fans to turn on along with the A/C and furnace, or have it on all the time to circulate the air inside your RV.

• Allows exact temperature settings
• Easy to install as it only requires minimal wiring
• Easy to use with only a couple of switches
• Can control both the A/C and the furnace
• Optimal control over the fan
• The screen is small and does not have a backlight

7. Emerson M30 Thermostat

The feature that I like the most about the Emerson M30 White Heat-Only RV thermostat is its simple and straightforward structure. If you are looking for something minimalist, you need to look no further than this thermostat. You only need to manipulate one lever to set the temperature.

Aside from being high-quality and user-friendly, this thermostat also boasts of its durability and reliability. Because there is no sophisticated and fragile circuitry to worry about, this thermostat is very low-maintenance. At most, you just need to give it a bit of cleaning now and then.

You will not also encounter problems with the installation. First-time owners can follow the straightforward instructions and colored diagrams included in the package. It also only needs a couple of basic tools and around half an hour of your time to get this thermostat installed.

Another great thing about this RV thermostat is that even though it is a mechanical and analog unit, it still has an ambient temperature thermometer. It is great because you can monitor if the A/C is not working as it should (the set temperature is significantly higher or lower than the ambient) and have it fixed before it worsens.

• Highly durable and reliable
• Comes with only one lever to operate, promoting ease of use and operation
• Minimal wiring work needed for the installation
• Features a separate thermometer for the ambient temperature reading
• Compact and minimalist design
• Resets the temperature after turn off the thermostat

8. Dometic 3109228.001 Control Center

This product from Dometic is not just a simple thermostat. It is designed to handle all of the climate control capabilities of your recreational vehicle.

In detail, this digital climate control system can create up to four zones in your vehicle. A zone is a place in your RV where you can assign a different temperature setting. For instance, if your bedroom area has a different A/C unit, then that is one zone.

For something so sophisticated, this Dometic RV thermostat can afford a surprisingly breezy operation. There are only five control buttons and an on/off switch at the bottom. Each button also has clear labels, so you can easily figure out how to use this thermostat even without consulting the user manual, though I still suggest that you read it first.

This RV thermostat also has a large, backlit LCD screen that shows your climate control system’s status. You can see the temperature setting, but you will also see the fan status, the zone you are controlling, and other essential information. The screen is large enough that you can see the display clearly from a distance. I can do so even if I do not wear spectacles.

The best feature of this thermostat model is that it is compatible with all Dometic climate control products. In other words, if you are a big fan of this brand, you can freely control all of them using this one panel. It can make the interior of your recreational vehicle free of clutter.

• Can create up to 4 different climate zones in your RV
• Easy to use with only five buttons for operation
• Has a large and clear LCD screen
• Compatible for use in controlling all Dometic appliances
• Does not come with initial programming instructions

9. Coleman Manual Thermostat

Another straightforward unit that first-time users will love is the Coleman Mach RV Camper Manual Thermostat. Its switches have clear labels, making them easy to understand. You have one that turns on the thermostat and allows you to pick between the A/C or the furnace. There is also a switch that lets you control the fan.

Another feature that I like about this Coleman Mach thermostat replacement is the time and effort-saving installation task. You do not need to hire an electrician or HVAC expert to install this thermostat for you. There are only a couple of wires that you have to clamp into the thermostat and color-coded instructions to make the process even easier. Just make sure that you turn off the circuit breaker of your RV beforehand.

One major reason why I love analog thermostats is that they are tough as nails. There are no sensitive electronics and only a few moving parts (most of which you will rarely move at all), so the likelihood of anything going wrong is minimal.

Of course, this camper mach manual thermostat is not as fancy as the other devices, but you can be sure that this one will still be working well after twenty years have passed.

As mentioned earlier, you can use this one RV thermostat to control both the A/C and the furnace. Unlike other thermostats that are only for furnaces or A/C systems, you can hook up both the heating and the air conditioning in this one housing. There is a switch on the panel that will allow you to switch between the furnace and the A/C.

For me, this RV camper mach manual unit’s simple design scores big time as it matches my RV interior. Such a minimalist thermostat does not interfere with your RV decoration style, be it modern, classic, or simple.

• Simple and easy operation with clear label switches
• Easy to install, not much wiring work needed
• Can control the A/C and the furnace
• Durable and does not require a lot of maintenance
• Boasts of a minimalist design complimenting RV interior
• Does not have a Celsius scale on the temperature

10. Honeywell TH5110D1006 Thermostat

One thing that truly impressed me about the Honeywell thermostat is that it can run both on batteries and hardwired into the RV electrical circuit.

Some people like having their thermostat hardwired because it eliminates the need to replace the batteries every couple of months. Other users do not mind using batteries as they do not spend that much time in recreational vehicles. In that case, they turn off the thermostat when not needed.

Speaking of the battery, unlike other non-programmable RV thermostats where you need to remove this non-programmable unit faceplate to gain access to the battery compartment, the Honeywell thermostat has an accessible battery door at the side that makes replacing batteries easier.

Another neat feature of this RV thermostat is the substantially-sized screen. It is by no means large, but it is big enough for you to see the ambient temperature reading and the temperature setting easily. It works great for people who want a simple to use thermostat while still allowing them to set the temperature to an exact value.

Another nice thing about the product is that you can use it to control both the A/C and the furnace. You do not need a separate thermostat for each. It makes the interior of your RV less cluttered. You do not need to deal with a wall that is full of control panels.

• Features an easy to read backlit display
• Comes with an easy to access battery replacement door
• Can run on batteries or hardwired into the RV circuit
• Can control the A/C and the RV’s heat pumps
• Has a large display size for the ambient temperature
• Not as easy to install

11. Dometic 3314082.000 Comfort Control

What appeals to most RV-owners, including me, is a large screen for optimal control. Notably, this Domestic thermostat comes with a large screen that uses large fonts and a bright backlit, ensuring all operations are breezy in daylight or at night.

Just like the original Dometic Comfort Control, this one can also control up to four different climate areas. It means that if your RV uses two different A/C units or furnaces, you can use this thermostat to control them separately. This way, you can create different temperature zones within your RV. For instance, you can make the living area a bit cooler than the rest of the RV.

You can also use it to control several different Dometic HVAC products. You do not need a separate controller for your A/Cs, furnaces, vent fans, and others. It would also be unnecessary to deal with an entire wall panel covered with different controllers. You only need an RV thermostat like this one.

I also particularly like the clicky buttons on the control panel. I prefer having that tactile feel that tells me that I adjusted the settings. I feel it is much better than touch-screen panels. The buttons also make it easier to set the settings for a particular function.

• Features a large and easy-to-read display size
• Can control up to four different climate zones
• Can hook up to several different Dometic HVAC systems
• Features clicky and responsive buttons that provide tactile feedback
• Useful in controlling the air conditioner and furnace
• Has a somewhat steep learning curve

12. Coleman 83303362 Thermostat

One amazing thing about this Coleman thermostat is that you can operate it without consulting the instruction manual once. As long as you can read the switches’ labels, you will not have any problem using this RV thermostat.

Installation is also a breeze. You will only need to do minor wiring. It has a color-coded installation guide to make it even easier, so you will know which wire goes where. Unlike the traditional RV owner, I have no real experience with electricity, and I could still install my thermostat in under 30 minutes.

Another neat feature of this non-programmable thermostat is that it can control both the air conditioner and the furnace of your recreational vehicle. Just position the thermostat switch to what you want it to control. You even have switches for controlling the ventilation fans .

Because it is a digital-analog thermostat (alkaline batteries power the LCD screen), you can bet that it will last for quite a long time. The lack of sensitive electronic circuits and processors means that there are fewer things that can potentially break.

• Effortless to operate and use with few control buttons
• Easy installation, thanks to its color-coded instructions
• Highly durable – easily lasts more than five years at least.
• The screen is a bit too small.

Best RV Thermostats Buying Guide

Here is what you need to remember when you are shopping for the right RV thermostats – it will probably be the last one that you will ever buy if you are lucky. To make sure that you will not be wasting your time, energy, and money on a subpar RV thermostat to your expectations, here are some of the factors you have to consider.

Built-in features – In the past, RV thermostats were only capable of only the basic functions, including setting the temperature up or down. Nowadays, these best RV thermostats can do so much more.

Before you go shopping for a new thermostat, it is best to make a list of the features you would like to have. Would you like Bluetooth connectivity so you can control the thermostat using your phone? Or would you like the one that automatically adjusts, depending on the outside temperature and the number of people?

Are you looking for a programmable RV thermostat, or maybe you want something simple? If you prefer a simple one, you can just go with an analog thermostat. It is the most basic RV thermostat that you can get. It also usually just comes with a slider that lets you adjust the temperature up or down.

Types – Speaking of analog, it is one of several different types of RV thermostats that you can choose from. Analog thermostats are the oldest and most basic types. It would be beneficial to get these units if you are only looking for superior reliability and simplicity. However, aside from adjusting the heat or cooling of the A/C, you can’t expect these types of thermostats to do anything else.

If you want your unit to be a bit more sophisticated, you can choose the electronic RV thermostats. These models have the same function as analog thermostats, but instead of a slider, you have a digital LED screen that allows you to set the temperature to the exact value.

You can also go for the communicating type of thermostat. These units are the newest ones to come into the market. You can control this type of thermostat from anywhere using an app that you can open on your phone. You can do all sorts of things with this type of thermostat. You can even set what time the A/C comes on and what temperature it is set to.

If you want something lower-priced than a smart RV thermostat, but with similar features, you can get the programmable thermostats. These items work almost the same way, but instead of using an app, you tweak the settings right on the thermostat control panel.

There is no such thing as the top-rated RV thermostat as this term is subjective. Each one has its sets of pros and cons, so just choose the type that fits your needs and wants.

Durability – This factor can be quite hard to discern as it is almost impossible to figure out durability when talking about electronic devices. However, there is a consensus that analog thermostats are longer-lasting compared to the other types. The main reason is its simplicity. There are fewer components in analog devices so there are only fewer chances of them failing.

However, if you want to gauge the true durability and overall performance of a particular RV thermostat, you will need to check out as many RV thermostat reviews as possible. You can also hit up YouTube for video reviews. If most customer reviews say that the thermostat is quite durable, then it is safe to assume that it will be a good buy.

Warranty – You need to learn one thing here. If a company does not offer any warranty or return policy, then you should look for another thermostat, preferably from another company.

Look for a thermostat that provides at least a one-year return and exchange policy. The longer the warranty period is, the better the product is usually. You should have enough time to test and abuse the thermostat. The warranty should cover customer error and other serious failures that might happen during normal working hours.

It is safe to assume that the longer a product warranty period is, the more confident the company is with their product. It means that you are getting a good deal.

Customer Service – This factor is in conjunction with the warranty. Even if a certain brand of RV thermostat comes with an impressive warranty, then the warranty means squat if it is difficult to make a claim.

Good customer service will also come into play when you need help with setting up the device or getting a defective item. It should be easy to get in touch with the customer service department, either by phone, e-mail, or live chat.

It would be great to get a thermostat that works perfectly out of the box, but there will always be a setback feature. The best place to find out how good the customer service is in a particular brand is the list of RV thermostat reviews. If a certain company’s customer service is bad, you will undoubtedly read a lot of complaints about them.

How Many Types of Thermostats for RV Are There?

Ranked from the least to the most sophisticated, the different types of RV thermostats include the following:

Analog thermostat – This type is the most basic and the oldest unit of thermostat available on the market. If you are the type of person who is not a big fan of overly-sophisticated thermostats that come with a lot of bells and whistles, you will love the analog ones.

These units usually just come with sliders to control the A/C, so you will need to estimate the temperature based on the markings. Moreover, you cannot get an exact temperature setting.

Electronic thermostat – This unit is a step up from the humble analog RV thermostat. The great thing about this thermostat is that you will have a digital screen and set of controls that will allow you to set the temperature to an exact value, even down to the decimal values. However, other than that, electronic thermostats don’t do anything different from analogs.

Programmable thermostat – An RV programmable thermostat is an electronic device that comes with a couple of other features and settings. For instance, it has a feature that you can use to set it to turn on at a specific setting at any time that you want. You can also program the thermostat to change the temperature settings at certain times of the day.

Communicating thermostat – This unit is the most sophisticated RV thermostat that an RV owner can buy. It can do all the things that the other thermostats can, and probably more. These units got the name communicating because you can control and program your RV Wi-Fi thermostat from your smartphone.

How Does an RV Thermostat Work?

Most RV thermostats use the phenomenon of thermal expansion to help control the setting of your air conditioner. Thermostats usually use bimetallic strips or gas-filled bellows.

A bimetallic RV thermostat uses two strips of different metals fastened together; hence, the name. You will also usually see this unit using iron and brass as temperature sensors. Because iron does not expand as much as brass, the bimetal sensor will curve outward when the temperature gets higher. It can cut off the circuit that turns on the compressor of the air conditioner .

However, the problem with bimetallic temperature sensors in most heating and cooling systems is that they take a long time to react to temperature changes. An alternative to it is the gas-filled bellows temperature sensor. As the name suggests, this system uses two metal discs with a gas-filled bellow in between.

When the room warms up, the gas in the bellows expands and forces the two metal discs apart, turning on the compressor. However, when the room cools down to your desired temperature, the gas will contract, and the metal discs will get in contact with each other again.

Who Makes the Best Thermostat for RV?

Several brands sell RV thermostats, but as always, some of them are not as great as the others. I have used and reviewed quite many RV thermostats, and I can honestly say that the best ones come from Dometic, Honeywell, Suburban, Emerson, TycoonWon, and Coleman.

If you happen to spot these brands while you are out shopping for a new thermostat, you should at least check them out. I can guarantee you that these brands can leave a good impression.

How to Tell If an RV Thermostat is Bad?

If you feel that your RV thermostat is almost ready to check out, but you are still not convinced enough to bother replacing it, note that the RV thermostat troubleshooting.

If you see any of these problems, you should replace your thermostat immediately; otherwise, you will be spending your next RV trip without your A/C system, and that would not be any fun at all.

Sign #1 – The thermostat has no power/unresponsive

If you turn the thermostat significantly up or down, and you don’t feel any change in the temperature inside the RV, then the thermostat might be on the fritz. If you have an electronic thermostat and the screen does not turn on even if you just replaced its battery recently, then it may be broken.

Sign #2 – The heater or A/C won’t turn on

If you turn up the A/C and do not hear the compressor’s humming, then the problem could be either with the wiring or the thermostat itself. The thermostat turns on the A/C compressor and/or the furnace, so if it does not, it is likely broken.

Sign #3 – The A/C or heater does not unload and is running constantly

The thermostat is responsible for turning off the A/C and/or furnace when the RV interior reaches the desired temperature. However, if you notice that the A/C or the furnace is constantly running and does not unload, then it is a sign of a busted temperature sensor in the thermostat.

Sign #4 – The actual temperature and the thermostat setting do not match

This sign is a bit more subtle than the other RV thermostat problems, and you may need to bring a thermometer around your RV to check. If the temperature in the different parts of the RV fluctuates, you may need to change the thermostat for something a bit more accurate.

Can a House Thermostat Be Used in an RV?

It will depend on what kind of thermostat you will be using. If you will be using a thermostat that will require wiring it to draw power from the RV, it will not work. Household thermostats run on 24 volts AC, but the power source of RVs only produces 12 volts DC.

If the thermostat runs on its battery power, it might work on your RV. However, not all battery-powered thermostats will work on RVs, so you will be taking a chance right there. You should use a thermostat made specifically for RVs rather than risk wasting money on something that may or may not work.

How Do I reset My RV Thermostat?

Unless you are an RV owner using an analog thermostat, you will need to occasionally reset the settings. The thermostat settings can get all over the place, like when your kids played with it. Or, if you have reset it in a while, whatever the reason, you need to reset your thermostat regularly. Now, here is the problem; not all thermostats can be reset the same way.

If you are lucky to have a thermostat with an actual reset button, all you have to do is press and hold it for around five seconds or so, and the unit will restart with all of its factory settings. With other thermostats, you will need to press several buttons at the same time. You can see the exact combination written in the instruction manual.

If your thermostat does not have a reset button and misplaced the instruction manual, you can try several things. First, if your thermostat uses batteries, you can take them out for around ten seconds and then put them back in the sled. If it does not work, you can also try reversing the battery direction for a couple of seconds and placing them back in the correct position.

If you have a hard-wired thermostat, there is no other choice except to turn off the main circuit breaker of the RV for a couple of seconds then turn it back on. In case any of the tips mentioned above did not work, the only thing you can do is find the instruction manual of your thermostat.

However, it does not mean you will need the actual physical pamphlet. You can easily find instruction manuals nowadays online. You need to do a quick search for your thermostat model + instruction manual, and you will most likely find it on the first page of the results.

Care and Maintenance

You may think that your RV thermostat is nothing more than a switch that controls the A/C, but it is a very sophisticated technology piece. With that said, you need to take good care of it. Fortunately, thermostat maintenance is not that hard at all.

The most important thing that you need to do is clean the inside of the thermostat to work efficiently. First, turn off the A/C, and then remove the front plate of the thermostat. You can then use a soft brush or a can of compressed air to remove any dust accumulated inside the thermostat. While the cover is already off, you can use this chance to replace the thermostat batteries (if it is battery-powered).

You can do other things to make sure that your thermostat is working properly is to avoid placing any sources of heat beside or near it. For instance, you should not place lamps or televisions beside the thermostat as they can trip the temperature sensors.

Whether your existing RV thermostat is nearing the end of its service lifespan, or you want to replace it with something fancier, do not settle for anything less than the best RV thermostat.

Since you have made it to the end of this buying guide for RV thermostats, it is safe to say that you already know what you need to look for. You will not be wasting your time and money on something that you will not be happy with later.

RV Air Conditioners – How They Work (Complete Guide)

As summer heats up, keeping cool in your RV is essential for an enjoyable journey. Your RV air conditioning system is responsible for providing that much-needed comfort, but have you ever wondered how does RV air conditioner work?

RV air conditioners work similarly to home units. They use a compressor to pressurize a refrigerant, which absorbs heat from indoor air, cooling it. The fan then circulates the cooled air while expelling heat outside. This process repeats until the desired temperature is reached.

In this comprehensive guide, we’ll explain the science behind RV air conditioning and the key components that make it all possible.

Key Takeaways:

• Understanding the components of your RV AC unit is essential for troubleshooting potential issues.
• Regular maintenance can help extend the lifespan of your RV air conditioning system .
• Choosing the right RV AC unit depends on factors such as the size and layout of your RV, personal preferences, and more.
• Energy-efficient RV air conditioners can save on costs and lower your carbon footprint.
• Optimizing airflow in your RV is crucial for maintaining a comfortable interior climate.

Understanding RV AC Components

RV air conditioners perform the critical function of keeping your motorhome cool and comfortable during your travels. These units are complex systems assembled from various components with specific functions. Understanding these RV AC components is essential before we dive into how they work together to cool your RV.

The above components work together to pump refrigerant gas through the RV air conditioning system and cool the air blown into your motorhome.

In a rig with a cooling and heating system, you can crank the A/C when it gets hot and humid, or and turn up the heat when it gets chilly. But to control your RV’s interior temperature via the HVAC system and furnace, you need one crucial component: an RV thermostat. Without it, you won’t be able to access any part of the on-board HVAC system. 

A thermostat is a system that can sense the ambient temperature inside a recreational vehicle, and communicate with the cooling or heating system to make adjustments, so that the temperature inside your motorhome is maintained at a desired level.

Another way to describe an RV thermostat’s role is that it serves as an intermediary interface between you and your on-board furnace and HVAC system . Based on the temperature information that it gathers from the sensors, the thermostat can tell these systems to turn on when the ambient temperature is higher or lower than your preset levels or turn off when that level is reached. 

The most technologically advanced type of RV thermostats can even change temperatures on its own per your preset preferences to better maintain a comfortable interior temperature at all times while saving energy.

An RV thermostat is typically hard-wired to your furnace and air conditioner through your motorhome’s 12-volt electrical system.

First, for everything to kick in, you must set a certain temperature level that you wish to maintain inside your motorhome. Using the built-in sensors, the thermostat can detect whether the temperature inside your rig is different from the desirable level that you previously selected. When a temperature gap occurs, the thermostat will send a signal to the air conditioning unit or furnace to turn on. 

The furnace or A/C will work to make the rig warmer or cooler, and when the same sensors detect that the preset temperature is achieved, it will cycle off the furnace or A/C. This mechanism means that you won’t have to manually turn your air conditioner or furnace on and off, but let the RV thermostat automatically work to keep you and your companions comfortable at all times.

A common question by fellow campers is whether a residential thermostat can be installed in an RV. The short answer is no, you cannot use a typical residential thermostat in a recreational vehicle. The reason is that due to their size, recreational vehicles tend to have simpler and less powerful heating and cooling systems, so they often use smaller thermostats. In addition, a thermostat for travel trailers will typically have a high/low fan speed to better control the interior temperature. 

And most residential thermostats are designed to use 24 volt AC power, while the power source in RVs are different. These vehicles run on the 12-volt DC system to charge the battery and power the engine’s electrical components, while the 120-volt AC system powers all electrical appliances and power outlets.

That said, you might come across a few thermostat units that can work with both. If for whatever reasons you’re looking for such a double-duty thermostat, double-check the product’s specifications as well as taking some time browsing the reviews to see if a particular model does function properly in both the home and the motorhome.

• Comfortable living: Unless you can be sure that you will always be camping in mild climate and perfect weather, which is very unlikely, you will definitely be using your A/C on the hotter days and the furnace on the chilly days. And you must have the best RV thermostat to make both systems work. Even if you can live without them during the day, being too hot or too cold can mean loss of sleep at night.
• Energy efficient: The great news is that many recent, more advanced models of RV thermostats come with microprocessors to allow you to set the temperature not only while you’re at home but also when you’re asleep or away. This means that these will save a lot of energy and cut down your electricity costs by, for instance, cranking down the A/C for 8 hours during your sleep. A one-degree reduction in one hour will save energy by around 1%, which would add up more quickly than you might think. 

Another energy-efficient feature of a typical RV thermostat is a high/low fan speed option. The high speed option allows you to heat or cool your rig quickly, and then when the desired temperature is achieved, you can turn the fan to low just to maintain that temperature while saving on electricity. This also means that the best RV thermostats can keep the interior temperature close to your desired level with minimal fluctuations for utmost comfort.

• Compatible with any RV system: If you have a heating system only, you can opt for an economical thermostat for furnace or get a thermostat that works with both a heating and cooling system. Whatever your rig has, you can get a versatile thermostat that is compatible with any system.
• Built to last: Getting the best RV thermostat and even having it installed by a professional can run you a few hundreds dollars, but this is an investment that will benefit you for at least a decade to come. The best RV thermostats on the market can last up to 15 years with proper use and maintenance and usually offer decent warranties, so your initial investment will pay for itself very soon down the road.

RV thermostats indeed come in all shapes of sizes but the market ‘s models could be categorized into four types: analog, digital, communicating and programmable. Which type would be ideal for your HVAC system depends on your needs for temperature control.

Analog Thermostats

Basic and practical, analog thermostats are compatible with almost any recreational vehicle. In addition, models of the type are affordable, making them popular with first-time campers and budget travelers. The downside is once it comes to the accuracy of temperature reading, analog thermostats often fall behind their digital counterparts. 

What’s lacking in these thermostats is they don’t set a precise temperature but more of a temperature range instead, since they use sliders as a means for temperature selection. This might not be a problem for many campers though, as long as the thermostat can crank the A/C when it’s hot and turn on the furnace when it gets chilly, so analog models are still widely used. These simple, easy-to-use devices will work for many different RVs, and will never go out of style.

Digital Thermostats

Being built with advanced features for modern requirements, digital thermostats boast first-class functions and excellent reading precision. RV digital thermostats have very similar working mechanisms to the old analog type, except they are electronic and are very accurate at detecting ambient temperature. These models have microprocessors that compare the actual temperature of the rig to the preset desired temperature. Models of the type cost more than analog thermostats though. And while analog models are simple, digital models have different and more complicated interfaces.

Programmable Thermostats

Programmable RV thermostats are a later invention, and allow you to program your desired settings into the thermostats memory. This means they are more convenient and easier to use. If this functionality is what you’re looking for, but find communicating thermostats (the most advanced type) too expensive, then a programmable thermostat is probably the best RV thermostat for you. 

As the name suggests, programmable thermostats can be programmed and optimized to the liking of individual campers. With these models, you don’t get all the features a communicating thermostat provides. However, with the memory system, all you have to do is set your desired temperature once and you’re good to go, without having to spend much time adjusting your thermostat. Waking up to and coming back to a comfortable home on wheels is never easier. Needless to say, models of the type earn a shower of praise from those that favor both convenience and living comfort. 

Communicating Thermostats

The communicating RV thermostats are the most advanced of the bunch, and multi-system communicating thermostats can be integrated with automated systems. These thermostats give the user complete temperature control via a wireless communication system, hence their name. Communicating thermostats allow you to regulate temperature remotely from any point in your RV. Also, many models of the type have phone apps that you could use to get updates about temperature and make changes in times of need from outside your rig. 

However, the technology is relatively new, so the offerings on the market might not have as many reviews as thermostats of the other types for you to rely on when shopping for the best RV thermostat for your rig . And surely they are the most expensive too.

The Best Thermostats For RVs: An In-Depth Review

Without further ado, below is our carefully selected list of the very best RV thermostat models for the money. There is something for every camper here, whether you’re looking for a basic, economical analog model, or a handy digital or programmable thermostat for better temperature control.

That said, if you’re not familiar with the different types of RV thermostats, or don’t know what to look for, skip to the next section to learn more about the pros and cons of each type of thermostat and the important buying criteria.

Why This Is The Best: 

Being both light and compact, TH5110D1006 of Honeywell could be put to good use in all kinds of settings. With an easy-to-see digital display, the Honeywell thermostat allows RVers to grasp the current temperature at a glance. In addition, the display of TH5110D1006 incorporates back lighting so people could check out readings in low light conditions. As a result, those that often have to travel at night and don’t want to deal with obscure readings think of Honeywell TH5110D1006 as the best RV thermostat. 

In use, the robust push-button control interface of the thermostat made by Honeywell means adjusting the interior temperature is a walk in the park. With TH5110D1006 by your side, you would be able to set the temperature inside your rig to your liking. As for power, TH5110D1006 of Honeywell is designed with two options: batteries and hardwire. The battery compartment of the thermostat from Honeywell proves to be highly accessible, thus, it’s a breeze to swap batteries in times of need.

Regarding post-purchase support, Honeywell backs its digital thermostat for campers with a five-year warranty. Hence, if your TH5110D1006 fails due to defects, you could claim a free replacement.

This is an upgrade to my Flagstaff camper. It was very easy to replace and it is maintaining an even temperature in the rig. As a result, it is using less propane than the inaccurate Coleman-Mach that came as OE. As a bonus, it will operate the air and heat automatically, switching from one to the other as outside temperatures dictate. As a mod for a camper, you can only have one fan speed without adding an additional switch, however I kept the high fan and taped off the low fan wire and haven’t missed a thing. There are videos that can help you through the modification if you need the assist. This is less expensive than the OE replacements and a far superior product. Shared by Samantha Harrell

I ordered this thermostat to replace an identical thermostat in my 2005 Keystone Sprinter. The original device would start the furnace only if set at 90 degrees. I needed two screwdrivers: one to remove the old device from the wall, and another to loosen the screws that secure the wires in the connectors. I taped the wiring diagram to the wall and donned my headlamp. Less than 10 minutes later, I had the new thermostat mounted to the wall and the wires connected. Now the furnace starts and stops and cycles correctly. It was a quick, easy repair that didn’t require a service call from a very expensive RV service. Shared by Gatos4

This is a 12 volt, dual function (a/c and furnace) control unit made for RVs that have Coleman-Mach thermostats. I live in a 2000/01 Arctic Fox 26X travel trailer and recently replaced the furnace, but the thermostat wasn’t working correctly before I replaced the furnace and has not worked correctly with the new furnace (which had a bad fan but was old so I replaced the entire thing since cost to repair was so high). With the old Coleman-Mach, the original thermostat, it would not turn off the furnace sometimes when the set temperature was reached. This was the only reasonable manual thermostat and I was told that if you have a Coleman-Mach, you MUST use a Coleman-Mach replacement or face rewiring issues etc. This one comes with excellent instructions, but essentially was 6 colored wires which were almost the same as the old. Backplate used same screw holes as the old one. Vendor sent it out immediately and it is working correctly and I am very happy. This should work on most older units and if you order here, it is a lot cheaper than ordering from the RV companies, most of whom don’e even carry this thermostat. I considered buying a second one just in case, but hopefully I won’t be living in this trailer such a long time that this one will fail! Good deal! Shared by Ewokinco

How To Get The Best RV Thermostat: Buying Criteria

The best RV thermostats usually allow you to control both the furnace and the A/C. However, more basic and affordable models might control only heat like a thermostat for RV furnace OR control only cool air, like an RV air conditioner thermostat . If your RV doesn’t have an air conditioning unit, you’ll want to consider the heat-only models. Do double-check the specifications of a particular product to make sure you get what you need. 

One of the most critical criteria for the best RV thermostat is the temperature selection, that is whether a model allows you to, with a high degree of precision, choose how warm or cool you’d like your interior to be. Especially if you often camp in extreme heat or cold, you’d want to apply quick and precise adjustments to the temperature in the interior of your rig through the thermostat. Because of that, a user-friendly interface that also offers precise temperature selection is key when you’re looking for the best RV thermostat. 

Analog thermostats tend to use sliders for temperature adjustments, which are very easy to use and adjust but not very precise. Meanwhile, digital thermostats allow for precision, thanks to display screens or dials that let you select an exact temperature. Both types have unique pros and cons, but just note that more precise temperature selection is extra helpful if you’re camping in extreme weather. When it’s freezing, you’d want the furnace to blast out heat fast so you can feel your feet again.

That said, the last thing you need is an unnecessarily complicated thermostat with a confusing control layout that prevents you from easily setting the temperature to your preferences. Take some time to browse the review section to see what other users have to say about the user-friendliness of a model.

If you want to set your preferences once and then forget about it, a digital programmable thermostat would prove to be very handy. If you want to be able to adjust the temperature from anywhere inside your rig and even from outside, a communicating thermostat would be ideal. 

That said, while these later, more advanced models offer precision and convenience, it also means there are more components that can malfunction, which can leave you freezing or melting until you have the unit fixed. If you can sacrifice a little bit of convenience to get a simpler, more reliable model that will be of good service for many years to come, an analog or a non-programmable digital thermostat might offer great value for money. An analog model would be the most reliable, while a digital model offers more precise temperature adjustments.

In order to operate as designed, a typical RV thermostat needs to be supplied with a constant amount of electricity. Thermostats for recreational vehicles nowadays tend to work with one of two power source options, either on batteries or hardwired directly into the wall and the onboard HVAC system. 

Take aspects of your travels and your rig into account to decide the source of power your thermostat should use. You’ll want to opt for the power source that best suits your needs. Battery-powered thermostats are very energy-efficient and usually include smart features, but as the batteries can run down quickly, you need to always stock up on batteries. Hardwired thermostats aren’t as energy-efficient but they are very reliable, although the major downside is they’re more complicated to install yourself and might require professional installation. 

You don’t have to be an expert electrician to set up thermostats for RV but to avoid potential headaches, it’s a good idea to make ease of installation one of your top considerations. Normally, by reading the accompanying owner’s manual, you can gain insight into the complexity of the setup process of a certain model. 

Also double-check the installation steps and requirements before buying to ensure a model will fit your RV, wire to your system properly, and be easy to install. It’s suggested that you read reviews of other RVers and see what they say. That is going to help you reach an objective conclusion. You can also seek assistance from the brand’s customer service, or ask questions on Amazon to get answers from both the brand’s representatives and experienced buyers. 

Before picking out an expensive hi-tech communicating thermostat for your rig, make sure you have the right kind of connectivity, typically either a Wi-Fi connection or connectivity via a smartphone app. Also remember that while basic analog models have been around for ages and hardly change at all over the years, fancy programmable or communicating thermostats are the newest, and that means new models with more advanced technology will be coming out regularly. You may need to replace a smart thermostat pretty soon to keep up with technology’s pace.

Reliability over the years

Generally, it’s ill-advised to subject electronics like thermostats to rough use but RVing regularly involves shocks and vibration. Hence, while looking for the best RV thermostat, you need to give ruggedness some thoughts. In the usual cases, you can determine how well particular models hold together by checking out their materials, designs, and fitness between parts.

All thermostats, no matter what type and how expensive, come with a plastic housing and electronic interior components and an array of tiny wires. Look for one made from heavy-duty materials that won’t crack, break, or come loose from all the shocks and widely varying temperatures down the road.

A thermostat should run for up to 10 years, even 15 years with the best RV thermostats, with little servicing, except for changing the battery exchange for certain types. You can rely on the warranty as some basis for a particular model’s reliability and longevity, and take some time browsing the review to see if the manufacturer actually honors the warranty and provide satisfactory after-sale services. 

The major brands with the best RV thermostats usually offer longer warranty, and this should speak volumes about how reliable a model is.  Don’t buy a thermostat for your RV from a company that won’t stand behind their products. 

All in all, when it comes to reliability, analog RV thermostats are probably the best, since they have far fewer moving parts and very straightforward internal working mechanism, making them a suitable option for campers who do not want the hassle of having to look for a new unit anytime soon.

Unless you happen to have sophisticated demands, it’s unnecessary to empty your wallet on a costly premium-grade thermostat. The market is filled with affordable and quality models so you don’t have to spend big bucks on thermostats. 

Nonetheless, it’s extremely important that you stay away from dirt-cheap models even if they seem to let you save a lot of money. Thermostats that come at unbelievably cheap prices rarely last long so the money you save from buying them would soon be lost to continuous replacements. For your reference, the price ranges for RV thermostats are as follows:

• Under $25: You will typically find basic, reliable analog thermostats in this price range. Nothing fancy, but they get the job done and are long-lasting.
• $25 to $50: The majority of RV thermostats today fall into this price range, including analog, digital, and programmable thermostats. 
• $50 and more: The most advanced digital, programmable and communicating thermostats will cost you north of $50. Some smart models can even cost more than $100.
• Including professional installation cost: Some units are best left to an electrician. A DIY thermostat upgrade can cost you anywhere from $25 to $150 for parts, or fall between $300 and $400 for both parts and labor if you have it installed by a professional.

All analog thermostats, even the newest models, will appear quite outdated and can stick out like a sore thumb. This might be a small source of concern for some folks, and you might find that a modern-looking electronic thermostat with a nice backlight feature will blend in better with the rig’s decor. Most RV thermostats for RVs come in white, cream, gray or black so you can match them to your RV’s aesthetic.

Well-Regarded Brands Of RV Thermostats

Numerous manufacturers make thermostats for recreational vehicles but in terms of reputability, several names clearly stand out from the rest:

Owing to substantial experience in producing goods for outdoor applications, Dometic knows exactly how to meet the expectations of RVers. That is why thermostats made by Dometic last a long time and give a splendid account of themselves in use. 

By constantly updating its technologies as well as production techniques, Coleman is capable of offering multi-functional and budget-friendly products to enthusiasts of RVing. Your budget is tight but you still wish to have a decent thermostat for RV ? Then Coleman is undoubtedly going to be your best bet. 

Honeywell is a major manufacturer of various systems for the home as well as recreational vehicles, including heating and cooling systems, air quality and humidity control systems and security systems. They have some of the best RV thermostats around, including standard heat-only thermostats, analog, non-programmable, programmable and smart Wi-fi models. Their models often boast at least 4.5 stars overall rating on Amazon, with at least a few hundred reviews per product to thousands of reviews for the best-selling models, so you have an excellent source of information there to pick out the best RV thermostat for your needs.

Dependable and reliable, thermostats of Emerson work well in plenty of environments and prove to be a breeze to maintain. Naturally, Emerson is held in high esteem by full-time RVers that value consistency but don’t really have much time to care for equipment.  

Considered to be one of the leading manufacturers of appliances for RV and associated accessories, Atwood is well-respected among RV communities around the globe. Thermostats of Atwood place emphasis on practicality as a result, they never fail to please. 

Suburban is a household name in the arena for RV furnaces, water heaters and parts, as well as analog RV thermostats. Although they only offer a few analog thermostats, including standard heat-only models, they receive raving reviews on Amazon, Walmart and other platforms for affordability, ease of use and installation as well as reliability over the years.

Most thermostats have a service life of up to 10 years, with the very best RV thermostats lasting up to 15 years. Like everything else, thermostats can malfunction due to old wiring, or a poor wiring job on a replacement unit. To make sure you detect an old or malfunctioning thermostat early on for timely diagnosis and replacement, you’ll need to be wary of the following scenarios: 

The A/C or furnace not switching on

If the A/C or furnace does not switch on, it might be that the thermostat is not sending and receiving the electrical signals it needs. If there is no power going to the thermostat, then it could be due to dead batteries in the unit, worn or damage to the wiring or harness, or wiring defects. 

To inspect the wiring for damage, you’ll need to remove the thermostat from the housing. If the wiring and harness are intact, you have just replaced the battery recently, and you’ve only had the thermostat for a few years, your best course of action is to take the unit to a professional electrician for testing.

The A/C or furnace refusing to turn off

If you find your heater or A/C unit running all the time without switching off even when the rig is already very cool or warm, especially even after you’ve pressed the power button, the culprit might be frayed wiring. Another reason is the thermostat unit might not have the correct calibration.

In this case, you’ll also need to remove the thermostat from the housing to inspect the wiring harness for damage.  If you find no apparent damage, take the unit to a professional electrician for diagnosis.

The unit not turning on

Another common malfunction of RV thermostats is when the unit has no power and does not turn on. You may also notice that there’s no change in the rig’s ambient temperature when adjusting the settings on your thermostat. The reasons for a thermostat not switching on can be loose wiring, loss of connection to the electrical circuit, or wiring being disconnected due to physical shocks and vibrations while traveling on rough terrains. 

As a result, the thermostat does not switch on or cannot identify the current room temperature. In the case that the unit does switch on but the display is dim, there might be damage to the screen, which might affect the unit’s ability to adjust the temperature setting.

Some thermostats are battery-powered. If after inspection, you’re sure that your electrical system is not the culprit, then it may be due to dying batteries. All you need to do is replacing the battery. But if replacing the battery doesn’t resolve the problem, the unit might be broken and needs to be replaced.

While we’re on this, do not buy used thermostats. While they might be more affordable, it’s not worth it. You don’t know how long they have been used, if they have been abused, and they also rarely come with a warranty, so in the worst case that they break down not long after, you will need to get another unit again. Always buy a new thermostat directly from the manufacturer or an agent that comes with a warranty.

The temperature in the rig not matching the setting

If you turn the heater up or crank down the A/C but don’t feel any change in the interior temperature, then it’s a sign that your RVs thermostat is on the fritz and may need recalibration to function properly again. 

Calibration of your thermostat is easy and should be done once a year, typically in the fall, before winter hits. Even with the more advanced types of thermostats, they still need to be calibrated to the correct temperature from time to time to ensure accuracy.

To do so, tape a thermometer rated for high accuracy on the wall next to your thermometer. Wait 15 minutes and check the temperature reading on both devices. A slight difference of +/- 3˚F is generally acceptable, but anything outside that range means your thermostat needs servicing.

Different models have different calibration techniques, so consult your owner’s manual. For instance, some screw-type thermostats can be tuned for accuracy using a small screw located on a coil inside the unit. 

An RV thermostat is not a simple replacement in most RV units; it will take a little bit of handiwork and finagling. It’s best left to the pros. But if you have a little bit of wiring know-how, and also you’ll have a library of online video tutorials to ease your steps, you can try to install it yourself. Expect to spend $300-$400 for both parts and labor if you have the work done for you by an HVAC professional. 

Before you start, you should consider a few things:

• Voiding your product warranty: Some thermostat manufacturers will void a thermostat’s warranty if you install it yourself in order to protect themselves from warranty claims caused by user negligence. Warranties can come in handy so that you won’t have to pay out of pocket should your unit malfunction before the common 10-year mark.
• Risks : Improper setup can result in electric shocks, accidentally blowing a circuit breaker, or causing damage to the thermostat unit, the electrical system or even the AC/furnace unit itself.
• Saving money vs later repairs: While the DIY route might be economical, any saving on installation will be offset by high heating and cooling bills or repairs to your rig’s HVAC system or the thermostat itself due to improper installation.
• Newer systems are complicated: Advanced systems will be more complicated to set up. Over the last few decades, RV thermostat has come a long way with marked changes, so configuring and wiring of these newer thermostats demand knowledge in electrical wiring. 

If you think you can handle it though, the process would look something like this for a digital thermostat, but of course, it’s crucial to follow your owner’s manual down to the letter:

• Tools: You will need a small precision screwdriver to loosen the screws in the thermostat. A set would only cost you around $20 for a high quality, top rated one.
• Safety first: When working with anything electrical, always remember to make sure you are not connected to shore power, turn off the breaker or disconnect power to any device before servicing it. Also disconnect the negative cable from your main batteries. 
• Remove the old thermostat: Pop the cover off and loosen the screws that hold the unit in place. You’ll see a set of color-coded RV wires ires connected to the thermostat. Using a precision screwdriver, disconnect the wires from the thermostat. Use tape to cover the blue and red wires as they will not be used. It’s important to make sure the wires do not touch each other during this entire process. 
• Wire in the new thermostat: Ensure the correct color-coded RV wires are connected to the correct numbered thermostat terminals. Normally, the terminals will have a screwdriver slot for securing the wires. 

Usually, it’s black wire to G (terminal 1, typically ground to the vehicle’s neutral system), white wire to W (terminal 8, typically the supply wire to the vehicle’s furnace or electrical heater), yellow wire to Y (terminal 5, typically the supply wire to the vehicle’s AC compressor), green wire to Rh (terminal 6, typically the supply wire to the blower fan’s high speed), and the other green wire to Rc (terminal 7, typically the supply wire to the blower fan’s low speed). 

Keep the jumper between Rh and Rc in place to allow the furnace and A/C to operate with the fan on the low setting. If your thermostat doesn’t have a High/Low fan switch, you can disregard this.

• Secure the new thermostat: Mount the back plate of the new unit to the wall using as many screws as needed while making sure it is level (this is important, as you will see in the next section). Then just pop the new thermostat into place. Before putting in the batteries, open the doors on the unit to make sure the switch is set to OFF.
• Reconnect power: Reconnect the negative cable to your batteries and plug in to shore power again. Press the power button until the display blinks and press the up or down arrow to increase or decrease the temperature setting. Once it shows the temperature you want, release the buttons and the display will stop blinking. 
• Set to AUTO: Then set the fan to AUTO and select either HEAT or COOL and you are good to go. Make sure you stock up on spare batteries before every long trip because if your batteries die, you won’t be able to operate your A/C and furnace.

Follow these following steps to fix a malfunctioning thermostat for your RV:

1. Check the setting

This step might seem obvious, but that’s why it’s overlooked by many puzzled RV owners. You’ll need to ensure that the thermostat is on the heater setting in the winter or the cool setting during the summertime.

Also note that if you leave the setting as ON, your heater or A/C unit will be continuously running without cycling on and off to save energy. Find the control panel on the thermostat and switch it to “AUTO” so that the thermostat will automatically and most efficiently turn the furnace or A/C on and off as needed. With the auto mode, the A/C or furnace only blows air when the system is heating or cooling the air inside the RV.

2. Check the level

Certain types of thermostats contain a small vial of mercury that must be level to ensure proper temperature control. This can be confirmed with a standard carpenter’s level. If the measurement is off, adjust the placement of the thermostat itself until it’s straight.

3. Turn the thermostat up or down

You might find that there’s little change in the ambient temperature. It might be that you’re forcing your furnace or A/C to work too hard. It’s better to set the temperature to 5 degrees lower than the outside temperature in the summer, and 5-degrees above the outside temperature in the winter to save energy. 5 degrees will also make a big difference in terms of your comfort. When turning the thermostat settings up or down, you should hear a clicking sound, then you will hear the supply register vents blowing or sucking in air from inside the rig.

4. Check the heat anticipator

If your furnace cycles on and off too frequently, adjust the heat anticipator. The heat anticipator is a small slider or lever below a scale with an arrow marked “longer” or something to that effect. Moving the level in either direction will increase or decrease the length of your HVAC system’s cycling time. Shorter cycling time though is better at maintaining the interior temperature close to your preset level.

5. Clean it the thermostat from time to time

You might have an older mechanical or analog thermostat in your pre-owned motorhome. This type of thermostats are prone to dust accumulation, which can jam the mechanical parts and cause the unit to malfunction. They require cleaning from time to time to maintain accuracy. 

If you purchase a pre-owned rig with an analog thermostat, malfunction might be due to the unit being clogged with dust. Take the cover off and blow it clean using an air compressor, or brush away any dust using a soft brush or a piece of cloth or even Q-tip. And if you see any surface corrosion, use an electrical contact cleaner to clean it, like the common WD-40 that can be purchased at any auto parts store or online.

FAQs About RV Thermostats

No. Residential thermostats are designed to regulate temperature in large spaces and they run on high voltages. Most residential thermostats are designed to use 24 volt AC power. Meanwhile recreational vehicles run on the 12-volt DC system to charge the battery and power the engine’s electrical components, as well as the 120-volt AC system to power all electrical appliances and power outlets. While a few residential thermostat models are compatible with use in RVs as well, you need to double check the specifications, or else you’d risk paring an incompatible thermostat with your rig.

If the battery in the unit is totally dead, you won’t be able to switch the unit on. And as their battery power is depleting, they will lose the ability to efficiently detect and regulate interior temperature. Because of that, you need to always have spare batteries on hand, or swap in new batteries around once a year.

The best RV thermostats on the market are reported to last 10 years or longer with proper care, with many models still being reliable after up to 15 years. Do note that thermostats might require regular calibration and servicing to restore their capacity for precise temperature selection.

With a digital thermostat, press and hold the “+” button and at the same time, press and hold the On/Off Mode button for three seconds. The LCD screen will show ― ― . Press the On/Off Mode button again to turn the system off. This will reset the unit. With an analog model, switch it off, then turn off the breaker that powers your HVAC system for 30 seconds and turn the breaker back on. Then turn your thermostat back on. It is now reset.

Different models usually have different calibration and maintenance requirements, so do consult your owner’s manual. Analog thermostats need to be cleaned or blown clean from dust buildup from time to time. The other types of thermostats would need recalibration to ensure accuracy. 

A good rule of thumb for energy-saving heating in the winter is to set your thermostat at 67° F to 70° F (about 20°C), as recommended by the U.S. Department of Energy. If you still find it cold, try increasing the temperature by only 1 or 2 degrees at a time. To stay cool and save money in the summer, you should set your thermostat to 78°F (26°C), and turn the temperature down only 1 or 2 degrees at a time. The better way to save energy is to set back the temperature of your rig at least 8° F for 8 hours or longer while you sleep. For every degree that you lower the thermostat, you can save 1% on your heating bill. This applies to cooling as well, since it takes less cooling and heating to keep you comfortable while sleeping.

That dial is the heat anticipator, which orders the thermostat to stop calling for heat before the ambient temperature gets too high.

So you don’t want to go out of your way to visit a store and pick up a thermostat? In that case, you could visit an online retailer, choose a model that you believe to suit your needs and have it delivered to you. Of course, to stay on the safe side, you should consider sticking to popular names such as Amazon,…

Dometic RV Air Conditioner Operation and Maintenance Print

Modified on: Mon, 5 Jun, 2023 at 10:37 PM

Every RV has one or more Air Conditioners that helps keep it cool.   They do differ from household A/C units in a few ways, but just like household units, they do require some maintenance.  Below we will take you through the operation, maintenance and some diagnostic tips on a Dometic RV Air Conditioner.

Dometic RV Air Conditioner Operation and Maintenance

TABLE OF CONTENTS

Maintenance

A/c expectation of operation, diagnostics.

• Pushing the mode button will bring you into FAN Mode.   Pushing the FAN button will allow you to choose the fan speed for the unit. HI/LOW.
• If you stay in the FAN mode it will operate just the fan and the A/C unit will circulate Air on HI or LOW, but it will not cool the air.
• Pressing the MODE button again will bring you to COOL MODE showing you a snowflake in the bottom corner.  Dependent on the previously chosen fan setting will decide if the fan will run all the time on HI or LOW or AUTO.  If Auto was chosen the fan will turn off and on with the operation of the compressor.
• It is suggested during very hot summer months that the Cool option be operated in HI fan speed only not AUTO.

• Once the fan operation is decided in COOL mode you may use the up and down arrows to determine what you would like the target temperature to be.
• The thermostat has foam pads on the back of it that are sensitive and will break down over time if pushed hard.  The thermostat should be pushed as if it is a touch screen, lightly.  No need to mash the buttons.

INTERIOR MAINTENANCE

• Interior return air filters should be cleaned regularly.   If you have animals, it should be done even more.
• The screens are there to block any foreign objects from entering and clogging the flow of air for the A/C. If they are not cleaned regularly, it will reduce the efficiency of you unit.
• Most filters are screens or foam filters. The screens can be cleaned with a damp cloth or a blower on an air compressor.   Foam filters can be cleaned the same way or replaced with like material.
• The Mixing divider above the ceiling assembly should be checked yearly to ensure no air is being mixed between the return and output sides. This can cause your A/C unit to freeze up and not cool your RV.

EXTERIOR MAINTENANCE

• Exterior maintenance will require you to climb onto the roof of the RV.  
• Confirm all power and breakers are off to the A/C unit.

• Repeat the process as necessary to rid coils of dirt and debris to allow proper airflow through the coils for operation.

• When in COOL mode, the difference in air temperature the blowing out will be 20 degrees lower than the actual room temperature air that is being sucked into the return vents.
• This means if it is 100 degrees in the unit when you first turn on the A/C that the air coming out cooling the RV will be 80 degrees.  It will take some time for the RV to begin cooling to the point the room temperature is 80 degrees and the air output is 60 degrees.
• This could take several hours depending on how high the temperature is in the unit or outside the unit.
• This should not be confused with the A/C not working properly.
• If you have determined the air coming out of the vents is not 20 degrees lower than the air temperature in the room, there could be a couple of causes.
• One cause could be that the coils are frozen.  By removing the return air vents you can examine to see if there is a sheet of ice across the coils.
• If this situation exists, you should check the divider as suggested in the maintenance suggestion.
• This can also be caused by the compressor not operating properly for multiple reasons.
• In the event the coils are frozen you can turn the COOL function off and turn the FAN option to HI and allow the coils to defrost.  This will sometimes result in water dripping from the ceiling assembly.  You should lay a towel down below this to catch the water.
• Other causes of freezing up could result from the A/C being in an area of an entry point into the unit that is constantly being opened and closed allowing warmer outside air in.  This results in a lot of condensation and can cause the unit to freeze.   Reducing in and out traffic can help with this as well.
• If you cannot find a remedy to this, you should have one of our facilities check the unit to ensure there are no leaks in the system or other component malfunctions.
• If we have our thermostat operating either the FAN or COOL option, the fan should be running.
• In the event it is not you should check the breaker panel inside the RV to ensure there are no tripped breakers.  Also, check the power pole the RV is plugged into to ensure there are no tripped breakers there as well.
• If this does not resolve the issue it should be brought to a service center for further diagnostic.
• If the thermostat will not come on to operate the A/C you should check the 12-volt fuses located near the 110-breaker panel inside the RV.   Ensure the fuse is not blown.
• Also, ensure your 12-volt system is charging and you have a good battery.

• Create New Wish List

Description

• Warranty Information

Camping in the summer months is a terrific way to spend your time. With the fresh air, the warm sun, and the cool breeze, you can really relax. But what if it becomes a bit uncomfortable. While we can't remove the sun from your campsite or keep the bugs away, we can definitely help with the heat problem. With our high quality air conditioners, you can stay comfortable throughout your trip. But what if you want more? What if you want to be able to keep your rig warmer in the winter? Or what if you want an air conditioner but don't want to deal with a loud noise or huge amp draw when you turn it on? Well, with this AC unit, you can have exactly that. With this model, you get an RV air conditioning unit that can operate at fewer amps, has less noise associated with its operation, and still has excellent temperature quality.

The ducted version of this model is in most ways the same as the non-ducted version. The outdoor unit measures 26 3/4" wide by 39 5/16" long by 13 11/16" high and the inner plenum unit measures 21 1/8" wide by 21 15/16" long by 1 11/16" high. This is a direct replacement for a 14" by 14" fan, which means that it is able to fit in the same space without making other adjustments. Available in black and white, this unit is ducted. It comes with removable screen filters that can be cleaned and replaced, which helps keep the unit working well for longer. The included remote control lets you control functions such as cooling, dry mode, sleep, and timing functions. The ultra low plenum design is also great, as it is sleek and streamlined. The functions can be displayed on both the remote and the plenum display. The chassis and canopy are made of a lightweight UV stabilized polypropylene material that helps it to withstand tough conditions. The low decibel readings mean you can enjoy your quiet time without fighting over the noise of your AC unit. This unit should be installed on a roof between 3" and 5 5/16" thick and is best installed on a flat roof.  This AC Unit comes with a preinstalled gasket.

For a powerful unit that's power-efficient and quiet, look no further than this unit. Have any questions? Contact us online or call our friendly Customer Care team today!

Why choose this model? Well, the answers are simple and numerous.

• This isn't just a cheap rooftop AC unit. Unlike other models that are made of cheap plastic that has been molded to shape around the unit, these are made from high-quality, tough plastic built to withstand what life throws at it. In warmer climates, other models of air conditioning units can melt from the heat. Not this one. Built tough and built durable, this AC unit will last you through a good many adventures.
• The remote that is included with the model allows you to control the temperature and settings of the unit from the comfort of your couch. Are you worried that you'll lose it? We've thought of that, too. Along with the remote is a wall carrier for the remote. Simply place it in an easy to reach location and rest the remote in it. The digital display on the inner plenum unit of the air conditioner allows you to control it without the remote as well, just in case you really do lose the remote.
• There are many amazing features on this RV AC unit, however, one of the best ones is the dry mode. Dry mode runs the fan at a higher speed, cycling more air and allowing moisture to collect on the coils so you can enjoy cool, dry air.
• The second amazing feature to pay attention to is the temperature monitoring system. If you like to leave the AC unit on while you sleep, you can often wake up to a freezing room. Because our bodies are naturally cooler when we sleep, leaving on the air conditioner can make your morning feel like ice. To prevent this, the air conditioning unit has a temperature monitoring system that senses the temperature of the surrounding air and adjusts to accommodate whatever temperature you've set it to, keeping you comfortable even through the night.
• Most RV air conditioning units blow the air from the top unit through the space between them and out of the bottom unit without a tube to control the air. With the air moving around in the space between, it loses some of the temperature quality and cleanliness. With the directional tube in this model, the airflow is controlled to provide optimal temperature quality and cleanliness.
• The low amp draw on this model enables it to not only keep your energy use lower than other models, but it allows you to use more than just the AC unit at one time. For other models that have a higher amp draw, you have to think about how many appliances are on that circuit, as the circuit breaker can only handle so much. With the low amp draw of this model, however, you have more room for other appliances. Saving you power and frustration, it's definitely the best model for energy efficiency. Both the Startup and Maximum Amp Draw top out at 14Amps.
• Because of the directional air tube, the high-quality design, and the efficient cooling and temperature control system, this AC unit produces air that is of very high quality. Temperature and humidity-controlled for your desired environment, you can feel the difference with this model.
• Perhaps the most important feature of this air conditioning unit is the noise level. Many of the models that come with your RV are loud and a bit obnoxious. Even those that you replace it with can be loud enough for you to notice it. This model, however, only produces 59.7 decibels of sound when on high. For reference, that's about as loud as a gentle rain; not loud at all. With this low sound level, you can relax in your RV, have a conversation, or watch your movie, all without competing with the AC unit.

Our Furrion Chill Air Conditioning System allows you to keep your RV or camper at your desired temperature. The 14 ,500 and 15,500 BTU rooftop air conditioners cater to different sized campers, while the different air distribution boxes feature a 3-speed fan and sleep settings to match your preferred comfort levels. An energy-efficient design means that you won’t be draining your RV’s battery excessively while using the RV air conditioning unit.

Our rooftop RV air conditioner units easily integrate into your camper or RV. Black and white color options help the system blend in seamlessly with a wide range of models, while an optional LED light on the Air Distribution Box adds dual functionality. In operation, Furrion AC units for RV are incredibly quiet at less than 80dB outdoor sound pressure level.

You can pair your rooftop AC unit with a manual control air distribution box or one with electronic control. For manual control AC units, you manually turn the unit on or off. It has a simple operation and is typically suitable for small RVs. Electronic control AC units include functions such as automatic restart and shutoff, so you don't have to constantly fiddle with the unit to keep the interior of your camper at a certain temperature. These RV air conditioning units are offered in either single zone or multi-zone controls. A single-zone unit with a thermostat lets you control the climate in a single space. For larger RVs, multizone systems are more suitable, as they let you control more than one RV AC unit with a single thermostat.

The Furrion Chill Air Conditioning System is built to complement life on the road in modern RVs and campers. Furrion Chill boasts 50% higher cooling capacity and 40% higher efficiency than industry standards. This means that you’ll get significant cooling power for the amount of energy it uses, ensuring you won’t run into flat batteries while staying off the grid. In addition, the RV and camper AC units are built with Furrion’s Vibrationsmart™ and Climatesmart™ technologies to protect the equipment from tough conditions on the road.

Furrion’s conversion kit allows you to easily replace your Coleman™/ Dometic™/ Advent™ Air Conditioning rooftop unit with a Furrion Chill AC rooftop system, while keeping your existing Air Distribution Box.
