Why Does My RV Furnace Keep Turning Off?

Why Does My RV Furnace Keep Turning Off

When you’re on the road, there’s nothing worse than having your RV furnace turn off in the middle of the night. It can be a real pain to get it going again, and it can be downright dangerous if you’re camping in cold weather.

In this blog post, we’ll discuss some of the reasons why your RV furnace might keep turning off. We’ll also provide some tips for troubleshooting and fixing the problem. So read on to learn more!

Why Does My Rv Furnace Keep Turning Off? The battery bank is low, or you’re having trouble getting propane or perhaps a faulty controller are the most common reasons why your RV’s furnace will not turn on. There are numerous additional reasons, however these are the top three most frequently reported causes.

What Should You Do If Your Rv Furnace Keeps Turning Off?  If you’re troubleshooting your RV furnace, the first thing you should do is check the battery bank. Make sure that the batteries are fully charged and that all connections are tight.

If the battery bank is not the problem, then you’ll need to check for propane. Check the tanks to make sure they’re full, and then check all of the connections from the tanks to the furnace.

Finally, if neither of those solutions solve your problem, then it’s likely that you have a faulty controller. The best way to fix this is to replace the controller with a new one.

Causes of RV Furnace Failure

Whether the furnace is on but there is no heat, check to verify if the propane is switched on. If the furnace still won’t start, try turning on a stove burner. This will guarantee that the stove receives propane. If the pilot won’t ignite, make sure you have enough propane.

If the pilot lights but the furnace won’t stay on, there may be a problem with the blower.

First, check your RV’s fuse box to make sure a fuse hasn’t blown. If that’s not the problem, see if you can find the source of the noise. It could be something as simple as loose screws or metal plates rattling against each other. If you can’t locate the source of the noise, it might be time to call a professional.

One last thing to check is the thermostat. If it’s set too low, the furnace will turn off automatically when it reaches that temperature. Make sure it’s set at least five degrees above room temperature to give the furnace enough time to kick on.

If you’ve gone through all of these steps and your furnace still isn’t working, it’s time to call a professional.

Troubleshooting an RV Furnace

If your RV furnace keeps turning off, there are a few things you can do to troubleshoot the issue.

First, check the thermostat and make sure it is set to the correct temperature. If it is set correctly, then check to see if the furnace is getting enough air flow.

The furnace needs adequate airflow to operate properly, so if the vents are blocked or there is something restricting airflow, that could be the issue.

Another possibility is that the pilot light is out; if that’s the case, you’ll need to relight it. Finally, if none of these solutions solve the problem, you may need to call a technician for assistance.

What to Do If Your RV Furnace Turns Off

Dirty air filters are often the blame for an inefficiently functioning furnace. Because air filters capture dust, grime, and debris like hair, they may limit or block crucial airflow over time, scorching the heat exchanger and preventing your furnace from performing properly.

If you have a gas furnace, check the pilot light to see if it’s still lit. A common issue is that the pilot light can go out if there’s not enough air flow, so be sure to keep vents unobstructed.

Another possibility is that your thermostat could be set too low, causing the furnace to turn off before it reaches the desired temperature. Or, if you have an electric furnace, a tripped circuit breaker could cause intermittent power outages and shutdowns.

Whatever the reason may be, troubleshooting your RV furnace is key to keeping yourself warm on those cold nights on the road. Be sure to check all of these possible issues before hunkering down for the night!

How do you reset an RV furnace after running out of propane?

Turn off the furnace’s gas valves to stop the flow of propane. Now turn on the stove. Allow the burner to burn for a few minutes to allow remaining gas from the valves and airflow to escape. Now carefully open the furnace’s gas valves and restart the furnace.

If the furnace doesn’t restart, it may need to be reset by flipping the circuit breaker. If you have an electronic ignition, you may need to push the reset button. Once the furnace is running, turn off the stove. If your RV has a propane leak detector, it will also need to be reset.

Check all the propane appliances in your RV to make sure they are working properly. If you smell propane, open all the windows and doors to ventilate the area. Do not use any electrical appliances until the area is well-ventilated.

If you have a carbon monoxide detector, it will also need to be reset.

Call a qualified technician to inspect your RV’s propane system if you cannot locate the leak or repair it yourself.

Why Is My RV furnace starting and stopping?

You could trip a high temperature switch, turning off the furnace flame, but the fan would keep running until cool air came out, at which point it would re-light. If the air temperature is higher than 130 degrees Fahrenheit, you should instal one or two extra air ducts to prevent the high temperature safety switch from cycling.

Another possibility is a loose wire at the thermostat, or a bad connection between the furnace and thermostat. If you have an automatic shut-off switch on your RV furnace, it may have been activated. This switch is designed to turn off the furnace if it senses unsafe levels of carbon monoxide.

If your RV furnace doesn’t seem to be getting power, check the circuit breaker or fuse box. The problem could also be with the gas supply valve being turned off, or a clogged air filter preventing airflow.

Will my RV furnace run on battery?

Yes, RV furnaces need power to operate. Although gas heaters may still provide heat using propane, a blower motor that distributes the heat into your home requires power. There are three methods for generating energy to power your furnace. You may utilise a battery, a generator, or a standard 110 volt outlet.

If you are using a battery, it is important to make sure that it is fully charged before using your furnace. It is also important to note that some RV furnaces are not designed to run on batteries alone and may require additional power from a generator or standard 110 volt outlet.

If you are using a generator, it is important to make sure that it is properly ventilated. Additionally, you will need to run the generator for a few hours each day to ensure that the battery stays charged.

Finally, if you have access to a standard 110 volt outlet, you can use this as your primary source of power for your RV furnace. However, you should still have a backup plan in case of power outages.


RV furnaces can be tricky to troubleshoot, but by checking all of the possible issues and following these simple steps, you should be able to get your RV furnace up and running in no time. If you are still having problems, it is best to call a qualified technician to inspect your RV’s propane system.
