RV Water Heater Switch On Or Off: 4 Tips To Learn About Heater Working

How to determine if the RV water heater switch on or off ? I have been asked this question plenty of times as an experienced RV person. If you are also looking for an answer to this question, you are in the right spot.

Read on as I’ll provide you with 4 tips about heater working. Stick with me till the end to enjoy your RV traveling. Let’s get started!

RV Water Heater Switch On Or Off

It is a common dilemma for many people to leave their water switch on or off in their camping vehicle. As an experienced RV enthusiast myself, I understand the pros and cons of both choices. Here are some factors that can help you in making the decision:

• For electric switches : If you have an electric control, you can leave it on without any problem. However, to avoid electricity usage, consider turning it off.
• For propane gas : On the other hand, if you have a propane heater, you should turn it off as excessive gas operation could be dangerous. 
• Keep the tank full : It is essential to fill the tank before turning on the heater. This will prevent the additional loss of energy to the heating element.

Determining the Switch Power Status

A couple of years ago, I got a cast-off Jay Feather Micro , and it came with a pre-installed FOGATTI RV tankless water heater . To my demise, I don’t know about the on and off switch . 

Although I solved the solution, I found out that many people faced this issue. Here is a quick guide on how to know the on/off status of 4 types of water heaters:

Electric Water Heaters

On most modern RVs, there is an inside switch in the thermostat of the electric water heater . However, in conventional models, you can usually find them outside at the hot water access panel.

There’s a probability of two switches on electric RV heaters:

• One for 120-volt AC;
• Another for 12-volt DC.

Ensure the 120-volt switch on the electric RV water heater is turned on if your RV is linked to an electrical outlet. By doing this, the hot water heater will use the 120-volt AC power source without problems.

If your RV is not connected, you might need to use the 12-volt DC supply to operate the heater by turning on the 12-volt switch.

Gas Water Heaters

If your RV water heater runs on gas, there will probably be a switch outside next to the propane tank. I found this switch, which regulates the Suburban heater specifically, next to the front passenger-side tire of my Cedar Creek Silverback fifth wheel. It has an indicator light that tells whether it is deactivated or switched on.

Recognize Your Switch’s Design

As I previously mentioned, some RV water heater switches are covered by access panels that must be removed to access the button. Moreover, try to spot a label on the heater mentioning “water heater” or “WH.”

In my RV, the switch was marked “Water Heater” and featured an arrow indicating which way to turn it on. Additionally, I discovered particular models where the letter “O” referred to an off switch and the letter “I” to an on switch.

If you are suffering from issues like accidently turning on of RV water heater switch, watch this video to resolve the issue.

Consult the Owner’s Manual

If you still need help understanding the layout or need help finding the switch, you should look through the user handbook that came with your RV. If you don’t have it, you can search for the model number online.

A Handy Way To Find Out The Switch Position

The position of the switch in your RV heater depends on a couple of things:

• Type of water heater;
• The manufacturer’s preference.

Here are some familiar places to look for it.

• Inside the RV: In some RVs, the switch is inside, typically behind a removable heater panel or next to the thermostat.
• Outside the RV: Some models have the switch outside the vehicle, usually on the driver’s side. To find the button, you should remove the metal panel.
• Adjacent to Propane Switch: On specific RV models, there might also be a propane switch adjacent to it. If the DSI light switch is on, your propane is not lit and isn’t heating your water. Nonetheless, there should be apparent markings on both switches.

I’ve also encountered a situation where the switch is hidden under a brass object, making it potentially difficult to reach if you have thick or large hands.

How Should You Proceed If the Switch in Your RV Heater Malfunctions?

Sometimes, even when there isn’t a problem with the heater, the switch can get stuck on or off. When this happened, I thought there was a heating issue because I could not turn the button. Thankfully, I discovered the issue was with the switch itself since it had corroded, which is typical for most RVs.

I used a small amount of WD-40 solution to lubricate the switch, and it started working correctly again. However, there might be further causes as well. Therefore, if the above solution doesn’t work for you, try one of the following:

• Circuit Breaker Examination: Check your circuit breaker first because it might have tripped. You may need expert help to resolve this issue. 
• Switch Replacement: Using a screwdriver, take out the switch to see whether there is any visible damage. If so, then replace the switch.
• Wire Check: Inspect for any loose wires. This can be the cause of your switch’s malfunction. Swap out the damaged wires.
• Gas and Electric Switches: Ensure the propane tank is complete if you have a gas water heater . Likewise, keep a check on the battery capacity for electric water heaters.
• Troubleshooting: If you have an electric water heater , make sure the power source is operational. Check fuse boxes for blown fuse.
• Blockage Inspection: Check your water heater for any obstructions hindering its operation.

Watch this video guide to find out the problems in your RV and solve them.

Crucial Highlights About RV’s Water Heater

Here, I have listed some facts about water heaters in an RV that you must know. Let’s check them out:

• Manufacturers: Atwood and Suburban are the leading manufacturers of water heaters for RVs. If problems arise, advice from other RV owners might be universally applicable.
• Tank Capacity: RV water heater tanks have a limited capacity ranging from 6 to 10 gallons. So, it’s essential to practice hot water conservation while traveling.
• Power Source: RV water heaters can run on propane, electricity, or engine heat. You can select any source as per your preferences. 
• Water Heater Types: Tankless and tank water heaters are the two primary varieties of RVs. Tankless heaters deliver hot water on demand and are more compact and energy-efficient. In contrast, tank heaters use gas or electricity to heat hot water stored in a tank.

Users’ Experience with the Switch of RV Heater

Now, I am going to share some of the reviews with you about water heaters so you can have an idea of how the people have experience: 

• Confusion About Switch Location: Bixler was curious about why the switch was located in an outside compartment and didn’t work well. Consequently, he was seeking a craftsman to address and resolve this issue.
• Power Source Concern: Jeff was perplexed as Cedar Creek Silverback 35IK’s heater only worked on electricity. He was in trouble as he was told there was a button to switch the modes, but he couldn’t find any.
• Switch Present Outside in Suburban: Rockfordoo shared that he needed help with the location of the switch on the heater in his Suburban. Later, he found that it was on the outside.

Do you leave the water heater switch on in an RV?

You can leave your RV’s water heater switch on if it is filled with water. However, it is recommended to switch it off when not in use to preserve battery life and prevent any damage.

Is it possible to replace the switch with a new one?

Yes, you can replace your heater switch with a new one. It is advised to get a switch made especially for a particular heating appliance.

How do I reset my RV water heater switch?

To reset the water heater switch, locate your reset button near the control panel. Press and hold it for a few seconds to complete the process.

How to lock out an RV’s water heater switch?

You can lock out your RV’s water heater switch using a lockout adaptor or a mounting clip. This safety precaution lowers the possibility of mishaps and increases safety by ensuring the switch cannot be accidentally turned on.

Summing up RV water heater switch on or off , there is no harm when the switch is on electricity. On the other hand, avoid leaving the switch on if you are on propane. You must be familiar with the location of the switch and how it indicates the power condition to determine its status.

Normally, you can find it next to the thermostat or outside the vehicle as a separate propane switch . If you encounter any issues, you can reset the switch using a reset button present near the control switch. If you are unable to solve the problem, it is best to seek professional help.

How to Know Your RV Water Heater Switch On or Off?

RV water heaters undoubtedly add to the enjoyment of camping. However, some often lead to more problems than they solve; like don’t even let you know when they are on. Something similar occurred with my new Cedar Creek Silverback fifth wheel that required some trial and error to resolve.

So how to know whether your RV water heater switch is on or off? It depends on the heater type (electric or gas-powered or both), the location, and the design of the switch. Switches may have clear labels or be hidden behind panels. And, of course, you can also check your faucet for hot water.

Let’s find out how to determine if your RV water heater switch is on or off, and what to do in different situations.

How to Know if Your RV Water Heater Switch Is on or Off?

Determining whether your RV’s water heater is on or off is easy once you locate it. You should, of course, check the faucets first to see if there is hot water. If not, and you’re unsure whether it’s working fine, you should try the following.

Electric Water Heaters

Modern electric heater switches on RVs are usually located inside the thermostat. However, they’re typically found by the hot water access panel outside on traditional models.

Electric RV water heaters may have two switches: one for 120-volt AC and one for 12-volt DC. If your RV is plugged into an electrical source, the 120-volt switch will be on, and the water heater should work. If not, then the 12-volt switch may need to be turned on.

Gas Water Heaters

If you have a gas water heater, there will be a switch on the outside of the RV near the propane tank. I found mine on my Cedar Creek Silverback fifth wheels Suburban heater by the front passenger-side tire. The switch may have an indicator light that shows whether it is on or off.

However, the switches on other models may be different. Some may be behind a panel, so you will need to look for it.

Understand the Design of Your Switch

As I mentioned, some RV water heater switches are hidden behind access panels that you must remove before operating the switch. But hidden or not, most usually come with labels. If you can’t find the switch, look for a label that says “water heater” or “WH.”

On my RV, the switch was labeled “Water Heater,” and it had an arrow that showed the direction to turn the switch on. I’d also found some models where the sign “O” indicated that the switch was off, and “I” meant that it was on.

Check the Manual 

If you can’t find the switch or are still confused with the design, try checking the user manual that came with your RV. If you don’t have it, you can look up the model number online and find it that way.

What to Do If You Can’t Find the Switch?

Sometimes you may not find the switches at all, and this can be very frustrating. 

The only way to check or turn the water heater on or off if the switches are really missing is to open the water heater case and remove the heater plate and then operate manually as instructed in your owner’s manual.

It is also important to fill the tank before the switch is manually turned on. Unless you do this beforehand, you risk destroying all the elements.

Can You Leave Your RV Water Heater Switch Always On?

Yes, you probably can. Leaving the switch on for convenience is a common practice, especially if the switch is difficult to reach. And it seems to make sense since the heater is only powered when there is electricity or propane connected to the RV, whereas keeping the switch on reduces wear.

However, you must ensure water is always available in the tank since empty tanks are a leading cause of RV water heater burst pipes. Also, if you don’t use the heater for an extended period, you should at least open the pressure relief valve to prevent the buildup of too much pressure.

Yet, I recommend against it when powering the heater with an inverter since it will put extra strain on the battery. Besides, the large load may trip the circuit breaker.

The best you could do is turn it off while driving and then turn it back on when camping. By doing so, you will save some power, and the battery won’t be overworked.

What to Do When Your RV Water Heater Switch Stops Working?

Sometimes, the switch may become stuck on or off despite there being no malfunction within the heater. I once had a situation where I couldn’t turn the switch on and thought the heater was broken.

Fortunately, I found that the problem was with the switch itself, which had become corroded, the usual case for most RVs. The solution was to use a little WD-40 to lubricate the switch, and it started working again.

However, there could be some other reasons as well. So, if my above solution isn’t for you take one of the following actions:

• The first thing you should do is check the circuit breakers since they may have flipped.  
• Check if there is a loose wire. This could be the reason why the switch isn’t working as it should.
• Pry out the switch using a screwdriver and check if there is any obvious damage. If so, you may need to replace the switch.
• If you have a gas water heater, check the propane tank to see if it’s full. 
• If you have an electric water heater, check the power supply to see if it’s working. You may have to go to the fuse box and check if there’s a blown fuse.
• Check the water heater for any blockages that may be preventing it from working.

RV Water Heater Switch On or Off? (Do You Leave It On?)

• May 31, 2023 /
• RV Water Heater /
• By James V. /

Dealers are not always correct... Of course, that is because RV makers may have hundreds of RV models combined. It is hard to keep track of every little detail each RV model comes with. This applies to the water heater switches. These switches are not always in the same place on every model.

The electric water heater switch is not always inside your RV like the gas power switch. Sometimes it is outside in the exterior panel. You can leave these switches on without any problem as long as you keep the water heater full of water.

To learn more about this switch, just continue to read our article. It has the information you want to know about so you know what to do with those switches. The key element will be water levels so be wary.

Do You Leave The Water Heater Switch On In an RV?

This will depend on your camping situation. When you are driving, your house batteries are probably not powering anything nor is your generator. If you leave the switches on you are not using any power as you drive.

In this case, it is okay to leave your switches turned on. There are only about two situations where you would have to turn those switches off. The first situation is when you have no water in your water heater tank.

You will burn out the element if you leave it on in this situation. The second situation is when you do not want to use any electricity while heating the water. Other than that, it is fairly safe to leave one, none, or both switches on as you camp.

RV Water Heater Switch On or Off?

This is a depends situation as well. There is nothing wrong if you leave the switch on at all times. Not much will happen except that the water in the water heater will be warm when you are ready to use some.

If you tend to have memory lapses when it comes to these smaller details, then it is best to leave it on so you do not have to worry about turning it on later. This is for the electric switch.

If you have a propane gas on-off switch then yes, you should turn that off when you are ready to drive to your next camping spot or home. There are some people who say to turn the electric switch off but this all depends on you and your situation.

You really have to make sure that the water tank is full of water if you are going to go that route.

Are You Supposed To Leave The Water Heater On?

Technically, you should turn the electric water heater switch off when you are not using the water heater. This will do two things. First, if your house battery is turned on, it will drain the battery and then you will have to wait till it recharges to use your electrical components.

Second, it protects your water heater if you drain it of water for when you are traveling. You will burn the element out if there is no water in the tank. Also, you do not need to have the electrical switch on if you are going to use propane to heat the water.

Nothing is wrong with having both switches on as the dual power sources will help with faster water temperature recovery. This situation is up to you as many owners prefer leaving it on. It saves time and hassles.

How do I Turn On My RV Water Heater?

The most important first step is to make sure the tank is full of water. If it is not then it does not take long to burn out the elements. Make a sign if you have to, to let everyone know to check the water level in the tank before turning the switch on.

The second step is to find the water heater access panel and take the door off. Then look for the electric water heater switch. Sometimes you have to look because it is hidden under wires or other key parts to make the water heater run right.

Once you find the switch, turn it to on and then put the access panel door back on and enjoy a nice hot shower. For the propane option, there is a little switch there is usually an indoor switch on the control panel on your dash or a separate control panel somewhere in your RV.

RV makers make this switch more accessible because you need to turn that propane off when traveling, etc. In case of problems turning your water heater on, read our article How do I turn on my electric water heater .

Forest River Water Heater Switch

There will be two locations and the first one is fairly standard for all RV brands and not just Forest River. That switch will be located in the water heater access panel. Just take the lid off and look around the drain plug to find it.

It is not always there but a couple of reset buttons should be nearby as well. The second location will be inside your RV or trailer. Exactly where may depend on your model of RV or trailer?

These interior switches are not always in the same spot but they will be next to the gas switch. Your dealer should be able to show you where the interior switches will be.

Some Additional Words

The only time there is harm when you leave the water heater electrical switch on is when there is no water in the tank. You need to make sure that tank is full of water when the switch has power running through it.

Other than that, it does not matter if you leave the switch on or take the trouble to turn it on every morning when you want a shower or hot water. Some people will say it should be off but that is not necessary just precautionary.

How To Turn on the Water Heater in Your RV

Most modern RVs are equipped with a water heater that’s super easy to start by turning a switch inside the coach to the On position. Some models have multiple control switches in different locations, such as the kitchen and bathroom(s), or even an exterior switch for the electric operation. 

Your owner’s manual will always be your best resource for which type of water heater you have and where its switches are located. You can also reach out to your RV’s manufacturer or find the model number on the unit. For example, if your model number is GC6AA 10E, you know you have a combo (gas/electric) unit signified by the ‘C,’ with a 6-gallon capacity, signified by the ‘6.’

Note: Depending on the type of water heater in your RV, there might be a few additional safety and operational requirements to consider. 

How To Turn on the Propane Water Heater in Your RV

RV water heaters either use an electric heating element or liquid propane (LP) gas to warm water. Conventional direct spark ignition (DSI) water heaters typically have tanks with six or ten-gallon capacities, while tankless RV water heaters provide hot water by passing it through a heated coil. 

If your RV has a propane-only direct spark ignition (DSI) water heater, you’ll only need to locate one type of switch inside your coach. Although you may have multiple switches in the kitchen and/or bathroom, each should  be marked ‘LP Gas’ or simply ‘Water Heater.’

To start the ignition sequence, turn one switch to the On position. This signals the unit to send 12-volt DC power to the spark and to open the valve to supply propane for the main burner. This begins the process of heating the water. 

When left on, a thermostat controls the operation cycle. When the set water temperature is reached inside the tank, the appropriate switches open to remove DC power and close the propane valve. When that temperature falls below a set level, the cycle supplies power and opens the propane valve to re-light the burner flame.

Technician Tip: If your RV has a gas/electric DSI water heater, using the propane method allows you to heat water when you’re on the road or boondocking without a reliable source of 120-volt AC power.

How To Switch an RV Water Heater From Propane to Electric

Most conventional water heaters that use propane and/or an electric element to heat water can alternate between these two power sources. To make the switch, simply turn the control switch marked ‘LP Gas’ or ‘Propane’ to the Off position. Then, turn the switch marked ‘Electric’ to the On position.

Technician Tip: Using propane and the electric element is often labeled as ‘Quick Recovery’ because it will heat the water in the tank quicker than using only a single source. Gas only is quicker than electric only.  

How To Turn on the Electric Water Heater in Your RV

Electric-only water heaters are rare in modern RVs. More commonly, you’ll have a direct spark ignition (DSI) water heater with propane and electric heating options. The electric heating element requires 120-volt AC power, meaning it requires that your RV is connected to shore power, running the onboard generator, or plugged into a portable generator. 

With the proper electrical supply, you can turn on your RV’s electric heating element by turning the switch inside the coach marked ‘Electric Water Heater’ to the On position. This electric heating method can be used independently or simultaneously with the propane heating method for quicker recovery. 

Technician Tip: Using the electric heating element can help you save propane for use with other appliances like your furnace or cooktop.

How To Turn on the Tankless Water Heater in Your RV

Although often labeled as “on-demand” water heaters, tankless models still need to be turned on to operate as desired. Most RVs with tankless water heaters have a control switch inside the bathroom or kitchen. There’s typically a single switch for the entire unit. 

Once your RV is parked at a campsite or boondocking spot , you can turn that switch on because the burner to heat water only turns on when a hot water faucet is opened. When that happens (in the kitchen, bathroom sink, or shower), water flows through a coil that is heated by a flame supplied by liquid propane (LP) gas.

When the faucets are closed, a valve removes power from the control board and the burner(s). Tankless water heaters are more efficient and have a much quicker recovery time than conventional water heaters. 

While they often boast that they can deliver a “limitless supply of hot water,” your supply will still be limited by the capacity of your freshwater tank (when boondocking) or the capacity of your gray water holding tank (when connected to city water).

How To Turn on a Water Heater with Manual Pilot Ignition

Water heaters with manual pilot ignition aren’t as common as they once were, but they’re still widely used in the off-grid market. Their proper operation begins with ensuring propane supply to the appliance by opening the valve(s) atop your propane container(s). 

From there, open the water heater’s access panel and locate the pilot knob. Turn the knob to the ignition position and allow propane to flow to the pilot’s location. Some models require holding the knob down to turn. 

For safety, use an extended stick lighter to light the pilot. This can remain on while your RV is stationary but must be turned off before moving. To do so, turn the knob to the Off position and close the valve(s) atop your propane container(s). 

If this process doesn’t work, the most common issues are insufficient propane supply and lack of 12-volt DC power to the water heater’s control board. Contact your local Camping World Service Center for help diagnosing and repairing your RV water heater. 

How To Operate the Truma Combi Water Heater

Many modern van camper manufacturers build their models with the Truma Combi water heater and furnace. The operation is still very simple but differs slightly from the others. Here are the basic steps for operating this type of water heater: 

• Reset the system using the control panel to navigate to ‘Settings’ > ‘Reset.’ This gives you a clean slate. 
• Navigate back to the home menu and select the Thermometer icon, which accesses the settings for your hot water heater. The first menu item will be the On/Off function for the water heater. Your setting options include ECO (for warm water), Hot (for hot water), and Boost (for quick heating). Select your preference by pressing the knob – Boost is recommended if you’re ready for a shower. 

This system is nice because it lets you set your preferred cabin temperature and furnace fan speed from the same interface. 

For those new to RVing, know it’s important to drain your tank at the end of the season. This is part of the process of winterizing your RV . View this video to learn how to drain your water heater tank.

To get the water heater to operate, should the water heater bypass switch be in the on or off position?

The exact position may vary based on the plumbing system design in your specific unit. At the basic level, the switch must be positioned to allow water to enter the water heater tank from either the fresh water tank or city water inlet. I’ve seen designs with 1, 2, or 3 valves, so I’d recommend consulting the manufacturer’s owner’s manual to find a diagram of the bypass design, if possible.

What is the year, make, and model of your unit?

How To Turn On And Use Your Electric Or Gas Water Heater In Your RV

Are you about to use your RV for the first time? I’m assuming this to be the case if you’re learning how to turn on the water heater, and I hope it’s the start of many adventures. The benefit of RVing as opposed to camping is that at least some of your home comforts come with you. One of these is a supply of hot water, but it does mean learning how to turn on and use the gas or electric water heater in your RV.

To turn your RV water heater on, first make sure it is full with water. Next find your RV control panel and if you have a gas/electric water heater and are plugged in, turn the electric on. If you aren’t plugged in or only have a gas water heater, then turn gas on. You can use both gas and electric.

So, the shiny new RV is stocked up, and ready to hit the highways and byways of whatever land your heart desires. RV water heaters are generally simple, reliable devices, and used correctly and looked after will last for the life of your RV. Depending on which type of water heater you have, you’ll need to carry out a definite routine to get started and to ensure that there’s water for that relaxing shower at the end of the day.

Turning On And Using Your RV Water Heater

To ensure that you have hot water when you need it, there are some steps to take and knowledge to be gained, so let’s get started.

Never Turn On Your Heater Before Filling The Tank

The first rule with a tank water heater is to get water into the tank before turning on the power. Failure to do this could result in serious damage and expensive repairs.

Most RV tanks hold 6 or 10 gallons of water, so a full tank weighs between 50 and 85 pounds, which can affect your fuel economy and road-handling. If you’re heading for a serviced campsite, consider filling up when you arrive.

How to Fill your RV Water Heater Tank

Hook up a clean hose to either the city water connection or your fresh water tank intake, and the other end to the supply spigot, whether it’s your garden tap at home or the supply provided at the campsite.

Make sure to use a drinking water safe hose and a water filter to ensure you have the best water quality. This is the water hose and RV water filter combination we use.

If you are using your city water connection, your RV water tank should fill automatically, if you are filling it with your fresh water tank, you will need to turn on your RV water pump.

• If you aren’t getting water in your RV water heater tank, make sure that the heater bypass valve is closed. If it’s left open, as often happens when the RV has been winterized, water will flow from the tank to the cold water taps and not to the heater.
• Now turn on a hot water tap, and let the water run. To start, it may splutter and flow hesitantly because there is air in the pie, but this will clear quickly, and the water will flow freely.  

With a tankless heater , there’s no tank to fill. Water will flow directly to the heat exchanger in the heater. You don’t need a bypass line either, although there ideally should be a bypass facility if you want to clean out the supply line in the future.

Turning On a Gas Water Heater in your RV

Gas heaters have become more sophisticated over the years, and most have automatic ignition, which makes life a lot simpler.

Autostart Ignition System

All you need to do is find the switch on your RV control panel marked “HEATER” or “GAS” and flip it on.

Check the indicator light which tells you whether the action has worked and that the heating process has begun. If it doesn’t light up repeat Step 1 until it does.

Turning On An Electrical Water Heater

An electrical heater draws a substantial current, so it will only work if you have access to an electrical power source such as at an RV park or generator.

If you are in a campsite with power outlets available, hook up the RV to the outlet provided or your generator.

Switch the water heater on using the switch situated in the cabin.

Many RVers prefer electrical water heaters because they are environmentally friendly, don’t require exhaust vents for burnt gas, and as long as you’re plugged into an electrical outlet, you’ll never run out of hot water.

Operating a Combination Gas/Electric RV Water Heater

When operating a combination gas and electric water heater in your RV, it is essential to know the basic steps to ensure proper functionality and safety. Here are the necessary guidelines to operate your combination RV water heater effectively.

First, locate the water heater control panel in your RV. This panel will allow you to switch between gas and electric modes, as well as control the temperature settings. Turn on the propane supply if you plan to use the gas option. Ensure that your RV is connected to a power source if you prefer the electric mode.

Now, select the desired mode (gas or electric) on the control panel. It’s possible to use both modes simultaneously, which can result in faster heating and recovery times. Once you have chosen your preferred mode, switch on the water heater. You will hear a clicking sound as the igniter works to light the propane burner in gas mode. In electric mode, the heating element will start to warm the water without any noise.

Keep an eye on the control panel during the initial startup. In gas mode, the control panel’s indicator light may flash, signifying that the burner is trying to ignite. If the burner fails to ignite after several attempts, a fault indicator may illuminate, requiring you to troubleshoot the issue.

Monitor the water temperature throughout your stay at the RV park or campground, adjusting the temperature settings according to your needs. Be cautious with higher settings, as scalding may occur more quickly.

To turn off the combination RV water heater, simply switch off the desired mode (gas or electric) on the control panel. If you plan to store the RV or travel to a new location, remember to switch off the propane supply and disconnect from the power source.

By following these steps, you can confidently and efficiently operate your combination gas and electric water heater in your RV, ensuring a consistent supply of hot water during your travels.

Troubleshooting Common Issues on your RV Water Heater

Pilot Light Problems

If your pilot light is not staying lit, there may be an issue with the thermocouple, ignitor, or the gas valve. First, check the thermocouple to ensure it’s properly positioned and clean. If necessary, adjust its placement or replace the thermocouple. If the issue persists, check the gas valve for any signs of damage or debris. Always remember to turn off the gas before working on any gas-related components. Ignitor not lighting at all, here’s how to test it. If you still can’t figure it out, here’s an article on the top 10 reasons your RV water heater won’t stay lit.

Heating Element Issues

If your RV water heater is not producing hot water, the heating element could be at fault. To check the heating element, turn off the power and remove the access panel. Use a multimeter to test the element for continuity. If there’s no continuity, replace the heating element. If the element is functional, check the surrounding components for any visible damage or corrosion.

Thermostat Malfunctions

A faulty thermostat can also lead to inconsistent water temperatures. Test the thermostat using a multimeter by checking for continuity. If it’s not functioning properly, replace it with a new one. Be sure to choose a thermostat with the correct temperature rating for your specific water heater model.

Anode Rod Replacement

The anode rod in your water heater helps to prevent corrosion and extend the life of the tank. Regularly check the anode rod and replace it if it’s worn out or corroded. It’s recommended to replace the anode rod every three years, though your specific water heater model may have its own specific recommendation. Be sure to consult your manual for guidance.

Reset Button

If your electric water heater stops working, try pressing the reset button, which is usually located on the thermostat or near the heating element. If the water heater doesn’t power on after pressing the reset button, there may be a wiring issue or another underlying problem that will require further investigation.

Wiring Concerns

Inspect the wiring connections for any signs of damage or wear. If your RV water heater is tripping your breaker, here is a full guide on how to fix it. Ensure all connections are secure, and replace any damaged wiring. Always turn off the power before working on any electrical components. For more complex wiring issues, consider consulting a professional to ensure your RV water heater is functioning safely and efficiently.

If you just can’t figure out how to fix your RV water heater, here’s how much it will cost to replace.

Energy Conservation and Efficiency Tips on your RV Water Heater

When you’re camping in your RV, it’s essential to conserve energy to keep your appliances running efficiently. With a few simple tips, you can make the most of your electric or gas water heater while enjoying a hot shower in your trailer.

To start, check if your RV has a combination heater that uses both propane and electricity. This type of heater is designed to provide optimal efficiency by using the best available energy source. When you’re connected to shore power, choose the electric option for your water heater, as it will save propane for other appliances.

Keeping your water heater properly insulated is another important strategy. Insulate the pipes and heater itself to reduce heat loss and conserve energy. Many RV water heaters come with factory-installed insulation, but additional insulation can further improve efficiency.

Here are several other tips for energy conservation and efficiency in your RV:

• Use cold water when possible:  Avoid using the hot water tap for tasks like hand washing or rinsing dishes, as this will save energy and extend the hot water supply for showers.
• Take shorter showers:  Limiting your shower time will reduce the need for the water heater to work constantly, ensuring you don’t deplete the hot water supply too quickly.
• Adjust the water heater temperature:  Set it to a level that’s comfortable for you without being excessively hot. This way, you won’t need to mix in as much cold water to achieve a comfortable temperature, conserving energy in the process.
• Monitor propane levels:  Keep an eye on your propane levels to ensure you always have an adequate supply for your water heater and other appliances.

By following these energy conservation tips, you can enjoy a more efficient and comfortable experience with your electric or gas water heater in your RV.

Weighing the Pros and Cons on Electric VS Gas RV Water Heaters

RV Water Heater Switch Not Working [5 Easy Fixes]

Your RV water heater switch not working means your heater won’t operate, and you won’t get hot water. The culprits that make the switch non-functioning are a defective or dirty switch and the switch losing contact with key wires. Also, the other factors to blame for this hitch are a stuck switch and loose connectors in the switch. 

So, for any of these factors, your RV heater switch can refuse to function anytime. But the good news is you can quickly fix these issues following our suggested approaches. 

Now, don’t waste time and thoroughly read this article to learn those quick resolving ways.

The major reasons for which your water heater switch becomes non-functioning and their quick solutions are: 

Note: You can also read how to fix the RV water heater igniter not clicking .

1. Switch Malfunction

The malfunctioning switch cuts power to your heater. And thus, your RV water heater can’t produce enough hot water. The switch stops working correctly due to its damaged contacts or loose wiring connections.  

Also, the defective electrical connection, shorted heating elements, overheated switch, and overloaded circuit are the other culprits to blame for this hitch. 

First off, check your water heater’s switch to understand whether it is malfunctioning or not. If so, we recommend you replace the defective switch. 

However, after replacing the switch, again, the new switch can become worse due to a faulty electrical connection. So, your next job is to check your heater’s electrical connections, circuit board, and heating elements. 

If you find anything bad, replace that one. In case you are not electronically inclined, then it’s better to contact an expert to deal with electrical issues. 

How To Check Your RV Water Heater Faulty Switch

We already told you to check the switch first to ensure whether it is non-functioning or not. Therefore, as an extension of that suggestion, we will here explain how you can check your RV water heater’s switch. So, to test the switch, follow the easy steps below: 

Step 1:  First, start the process by turning on your RV water heater. Then go near your water heater’s exterior panel and remove the panel’s plate.

Step 2: Now locate your heater’s switch and be ready to remove it (The switch via the plastic clips is held in a particular place. Therefore, removing the switch is not tough. Be careful while removing the button as the clip can break due to extreme force.)

Step 3:  Now, it’s time to test your water heater switch’s continuity using the multimeter. Finally, 0 continuity means the switch is malfunctioning. In case, after testing the switch, you find the 0 continuity, we recommend you replace the lousy switch 

2. Dirt Build Up In Switch Inside

If your RV water heater switch is located outside of your RV, the switch can get dirty. The dirt accumulation in your water heater switch inside makes the switch non-functioning. 

However, the switch becomes filthy when you don’t clean it properly or use it too frequently. 

When your RV water heater switch suddenly stops working, we recommend you clean its dirt. Cleaning the switch is very easy. Just take out the button and adequately clean it using a soft cloth.

3. Switch’s Loose Contact With Key Wires

Your RV water heater switch works in connection with your heater’s several key wires. The switch stops functioning when its connection becomes loose with your heater’s key cables. Using the switch for a long time can cause loose contact with key wires. 

The simple way to solve the above trouble is to check your RV water heater switch connection with the other key wires. And ensure the cables and switch are tightly joined together.

4. Stuck Switch

Your RV water heater switch is not operating because the switch is stuck in on/off or in a particular position. The stuck switch remains stiffly placed and doesn’t move from one position to another, or even the switch doesn’t move back a bit. 

The frozen switch can’t follow the command. And therefore, it stops working or becomes inoperable. 

Replacing the stuck switch is the prime way to settle this hitch. But as long as you don’t replace your heater’s stuck switch, we strongly recommend you use the breaker at your heater’s power panel.

Another important note for you is during the switch replacement, turn off the breaker. 

5. Fried Or Loose Connectors

The loose or fried connector of your RV heater switch hinders its functioning. The connectors jointly create electrical circuits in the controller. And then your heater’s switch functions perfectly. 

However, voltage fluctuations, power surges, or improper receiving of power are the potential causes that make the connectors fried or loose. 

When suddenly your water heater switch is not working, we recommend you to check the connectors in the switch. However, you better replace the entire switch when the connectors become faulty or loose. 

Is there a reset button on an RV hot water heater?

Yes! There is a reset button on an RV hot water heater. Usually, the reset button is red. And it is located behind the removable metal panel or near your heater’s thermostat.

Why is my RV water heater not heating the water?

Your RV hot water heater is not heating the water, mainly due to the low or empty propane tank, faulty thermostat, defective on/off switch, and other malfunctioning heating elements.  

How do I know if my RV water heater element is bad?

On your RV water heater, touch each screw on the element with the multi-tester. The lousy element will give you no reading or maximum reading. However, the standard reading is 10-16 ohms. To fix this issue replace your heater element . 

Why does my RV water heater only lukewarm?

Your RV water heater is only lukewarm because of the damaged or broken dip tube, thermostat malfunction, too low water temperature setting, or heater’s lousy heating elements. 

Final Thought

Hopefully, after going through the above-detailed guide, now you know why your RV water heater switches not working. When your heater switch stops functioning, find out which culprit is responsible for it and then fix the issue by yourself.

What To Do When Your Car Heater Won’t Work

W hen it's cold outside, your car's heating system provides warm air to make driving comfortable. Even if you live in a warmer climate, there will be chilly mornings when you'll want your car's heater to help warm you up while driving .

But if you live in a cold, demanding northern climate, a properly functioning heating system isn't a nice-to-have, it's essential. In addition to making your drive miserable, a heater blowing cold air prevents the defroster from removing ice and fog from the windshield, creating dangerous driving conditions that you should never ignore.

How Does a Car Heater Work?

Heat from a running engine is absorbed by coolant. To maintain proper engine operating temperature, the cooling system circulates the engine coolant through the radiator and heater core.

The radiator and heater core act like small heat exchangers to remove excess heat from the coolant. In a passenger vehicle, the heater control panel manages the components that regulate how much heat from the heater core enters the passenger compartment, to keep you warm and toasty. The heater control is also used to adjust blower motor fan speed and which vents the heated air exits.

What If My Heater Isn't Blowing Warm Air?

There are a few reasons why your car's heater can fail to blow hot air into the passenger compartment. Let's look at the most common causes and determine if they are something you can fix yourself.

Low Coolant

Low coolant level is the most common cause of poor heater output. To determine if this is the problem, when the engine is cool, remove the radiator cap. The coolant level should be at the top of the radiator neck.

Using a 50/50 mix of anti-freeze and distilled water, top off the radiator and fill the coolant reservoir tank to the "Max" line — be sure not to overfill the radiator or the coolant reservoir. With the radiator cap still off, set the parking brake, start the engine, and set the heater control to the highest temperature and maximum fan speed settings.

As the engine warms up, the coolant level may drop when the thermostat opens. If the coolant level drops, and being careful to avoid any moving parts (especially the cooling fans!), slowly squeeze the upper radiator hose to help remove any air that may be trapped in the cooling system. Top off the radiator and coolant reservoir tank again, if necessary.

If you need to keep adding coolant, check the radiator, thermostat housing, radiator and heater hoses , water pump and coolant reservoir for leaks. If any of these parts are leaking, check your owner's manual to determine which ones you can replace yourself.

If you don't see fluid puddling under the car, check the tailpipe for thick white smoke or a sweet-pungent odor. These symptoms indicate coolant is burning in the combustion chamber due to a bad head gasket, intake manifold gasket or other failed internal engine part. Replacing internal engine gaskets is not a DIY project.

Thermostat Stuck Open

The thermostat is a simple, but critical valve designed to block coolant from circulating through the cooling system when an engine is cold, allowing the engine to heat up and reach operating temperature quickly.

When the engine reaches operating temperature, the thermostat opens, allowing hot coolant to flow through the cooling system and heater core. A stuck-open thermostat prevents the engine (and coolant) from heating up.

Cold coolant flowing through the heater core can't produce heat and won't warm up your car's interior. A stuck-open thermostat also causes poor gas economy, elevated tailpipe emissions and engine damage. On some vehicles you can replace the thermostat yourself — check your owner's manual. Otherwise, your mechanic can do it.

Plugged Heater Core

Heat from the circulating coolant is transferred to the heater core. The blower fan pushes air over the heater core (similar to a small radiator), removing heat from the coolant. This heat is used to warm up the passenger compartment and defrost the windshield .

A plugged heater core restricts coolant flow and gives off little or no heat. With the engine at operating temperature, set the heater control to the full hot position, then carefully grasp both heater hoses. They should be very warm. If one is significantly cooler than the other, in all likelihood, the heater core is clogged. You can try flushing a clogged heater core with a garden hose.

A heater core can also leak. A leaking heater core produces a sweet odor and a slimy film on the windows, as well as causing low coolant level issues. Installing a new heater core can be difficult and should be done by a pro.

Electric Cooling Fans With a Bad Switch

Electric cooling fans that run constantly due to a malfunctioning switch, relay or controller prevent coolant from reaching operating temperature — similar to a thermostat that is stuck open. Due to the complexity of this circuit, diagnosis and repairs are best left to the pros.

Heater Control Valve Stuck

Some vehicles use a heater control valve that only opens (allowing hot coolant to flow through the heater core) when the heater control calls for hot air. The heater will fail to produce warm air if the control valve is stuck closed, leaking or disconnected from the heater control.

Follow the same steps to check if a heater core is clogged, only you'll also want to feel the heater hoses on both sides of the valve. If the hose connected to the engine is warm, but the hose from the valve to the heater core (the hose that goes into your car) is cooler, the valve is in the closed position.

Some valves are controlled by vacuum. Check that the vacuum hose is connected and not damaged. If the hose is okay, remove the hose and place your finger on the end of the vacuum hose and feel for suction, sort of like a vacuum cleaner hose, but not as strong. Leave it to your mechanic to repair if no suction is present. You can replace a heater control valve yourself.

Blend Door Stuck in Cold Position

The blend door regulates the amount of heat from the heater core that enters the passenger compartment. Electrical, vacuum or mechanical outputs from the heater control act on the heater blend door to deliver all hot air, all cold air or some combination of the two.

A blend door stuck in the cold position, due to a defective heater control, failed electrical or vacuum actuator or mechanical control cable will produce little heat.

Don't confuse the blend door with the mode door. Mode doors function the same as a blend door but direct air flow to the floor, dash vents and defroster. Repairing blend door problems is best left to an automotive air conditioning specialist.

The Last Word

It's important to address car heater problems as soon as possible. On cold days, a car that isn't blowing warm air won't be pleasant to drive, plus the situation places the driver and their passengers at risk if the windshield fogs up or ices over.

For your vehicle's heating system to work efficiently, and help prevent coolant leaks and engine mechanical problems, flushing the coolant every three to five years or 30,000 miles is key.

Some of the issues tackled here can easily be fixed at home while others require a mechanic. If you ignore the problem, it may cause a bigger and more costly issue down the road.

Dept. of Accidental Investigations —

How i upgraded my water heater and discovered how bad smart home security can be, could you really control someone's hot water with just an email address.

Kevin Purdy - May 17, 2024 11:00 am UTC

The hot water took too long to come out of the tap. That is what I was trying to solve. I did not intend to discover that, for a while there, water heaters like mine may have been open to anybody. That, with some API tinkering and an email address, a bad actor could possibly set its temperature or make it run constantly. That’s just how it happened.

Let’s take a step back. My wife and I moved into a new home last year. It had a Rinnai tankless water heater tucked into a utility closet in the garage. The builder and home inspector didn't say much about it, just to run a yearly cleaning cycle on it.

Because it doesn’t keep a big tank of water heated and ready to be delivered to any house tap, tankless water heaters save energy—up to 34 percent, according to the Department of Energy . But they're also, by default, slower. Opening a tap triggers the exchanger, heats up the water (with natural gas, in my case), and the device has to push it through the line to where it's needed.

That led to me routinely holding my hand under cold water in the sink or shower, waiting longer than felt right for reasonably warm water to appear. I understood the water-for-energy trade-off I was making. But the setup wasted time, in addition to potable water, however plentiful and relatively cheap it was. It just irked me.

Little did I know the solution was just around the corner.

Hot water hotspot

• Attention! Kevin Purdy
• Nothing'll happen. Just touch it. It's what you wanna do. It's there for you to touch. Kevin Purdy
• The Rinnai Central app. It does this "Control failed" bit quite often. Rinnai

I mean that literally. When I went into the utility closet to shut off the hose bibbs for winter, I noticed a plastic bag magnetically stuck to the back side of the water heater. “Attention! The Control-R Wi-Fi Module must be installed for recirculation to operate,” read the intense yellow warning label. The water heater would not "recirculate" without it, it noted.

I found the manual , unplugged the water heater, and opened it up. The tone of the language inside (“DO NOT TOUCH,” unless you are “a properly trained technician”) did not match that of the can-do manual (“get the most from your new module”). But, having read the manual and slotted little beige nubs before, I felt trained and technical. I installed the device, went through the typical “Connect your phone to this weirdly named hotspot” process, and—it worked.

I now had an app that could start recirculation. I could get my shower hot while still in bed, or get started on the dinner dishes from the couch. And yet pulling out my phone whenever I wanted hot water felt like trading one inconvenience for another.
