Rv Furnace Won T Turn On – Maintenance-free RV ovens work similarly to the ovens in your home. However, there are things you can do to make it run more efficiently and troubleshoot if you run into any issues. For example, what happens when the furnace on a 2003 Winnebago Brave, which runs on liquid propane, starts to fail? How to complete RV furnace troubleshooting to diagnose and resolve problems?
In this in-depth video lesson, RV maintenance and repair expert Dave Solberg teaches you how to troubleshoot your RV furnace. To help you better understand furnace maintenance, he begins by explaining how the furnace works, part by part. You’ll know what happens from the moment the fan starts up because the thermostat requires heat to the end of the line when the thermostat realizes that the inlet temperature has been met.
Rv Furnace Won T Turn On
Dave starts with the basics of RV furnace troubleshooting. He stresses that it’s important to note that the heater on your RV works by drawing in air from the inside and heating it, rather than drawing in outside air for heating.

A thermocouple mounted on the back of the oven senses when the oven is overheated and automatically shuts down the system. Good airflow ensures that the oven does not overheat, and proper airflow is necessary in any system, whether that system uses ventilation ducts or corrugated pipes (AKA elephant hose).
To ensure optimal airflow, you should always avoid blocking vents with area rugs and piling objects on or near corrugated pipes. It doesn’t sound like a big deal at first, but putting weight on the tubes can compress them and restrict airflow, resulting in inefficient or often unresponsive heating.
According to Dave, what you need to check if your device won’t run: first you need at least 10.5 V, so if your battery is sulfated, the LP system might start up, but won’t run too long. The fan won’t spin fast enough to lift the sail switch and transfer heat. However, when the sail switch is lowered, it doesn’t stop the fan from spinning, which could mislead fans into thinking that heat would be emitted if the fan was in motion. If this is the case with your furnace, it’s possible that your battery isn’t generating enough voltage to raise the sail switch.

If yes, great! Continue to Stage 2. However, if your blower is not working, it may be because it is not receiving 12 volts of power. The first thing to check is the fuse. Sometimes a surge of current can blow them away, so always make sure you carry some spare parts of each size your fuse board uses.
If your fuse is good, it’s time to check the battery. If it’s too cold, your battery’s performance may drop significantly and there won’t be enough power to spin the blower motor. Check your battery voltage and if it is low try connecting to onshore power or using a generator.
If you don’t do these two things, you could have a real hardware problem with your thermostat or heater motor and you’re probably better off calling a professional.
How Does An Rv Propane Furnace Work?
Is your engine running but only blowing cold air? And your RV oven isn’t trying to light up?
This is most likely due to one of your oven’s safety features. One that is often faulty is called a “sail switch”. This is a switch that is activated by the airflow generated by your blower. Sometimes it can get dust, dirt, or pet hair in the way of pressing down. And if it doesn’t press down, the oven means the fan has failed and won’t try to ignite the flame.
If your sail switch looks good, your oven control panel may be suspect. Moisture in the air or condensation and accumulation on the board can short circuit and cause the board to malfunction. These boards are fragile, and those traveling full-time in the winter will often carry a spare with them. They are not cheap (about $100 USD at the time of writing), but are well worth a try as this is a very common cause of failure.
Ways To Heat Your Camper You Probably Haven’t Thought Of
It could also be your high temperature sensor. This is a probe that checks if the flame temperature is above a certain threshold. If it reports a bad value, the furnace will think it is overheating and cut off the gas supply.
Does your RV oven light up for a short time, but then turn off almost immediately? There are two possible reasons for this behavior.
First, check your gas pressure. Turn on all your stove burners. Is the flame strong and blue? If the flame is weak and/or yellow, your gas pressure may be too low. Check your propane level and try with a fully filled tank.

If you’re still having problems with a full propane tank, it could be your regulator. If your regulator is more than 5 years old, it’s a good idea to get a new one because they’re fairly inexpensive and crucial to the operation of many of the devices in your RV.
Another factor is height. Some RV furnaces have trouble running at high altitudes. Unfortunately, the only solution in this case is to go back to lower altitudes and consider alternative furnaces that perform better at high altitudes.
The last component to check is the “flame sensor”. This is a transducer that generates an electric current when exposed to an open flame. It is important that the distance is correct and free from corrosion.
Ask Dave: My Rv Furnace Gets Too Hot To Touch. Is This Normal?
Note that you must disconnect the propane gas line to test this part, so it’s better to have it checked by a professional.
Finally, as mentioned earlier, your console may be damaged. Sometimes all the correct signals are sent to the RV furnace control panel, but it will interpret them incorrectly and shut off the gas as a safety feature.
Does your RV oven light up, run for a while and then randomly shut down? If so, don’t ignore the signs. It could be a precursor to an impending failure that could be more permanent.
How Does An Rv Furnace Work?
Check your battery, propane pressure, and regulator, and if the intermittent problem persists, consider replacing your control board.
If your oven is always on, congratulations! You now have a working RV oven and you will be kept warm! An indoor heater is an essential component of an RV’s system because it generates heat, which is important in colder locations or in winter when outside temperatures can be quite low.
Ovens can sometimes fail to ignite for a number of reasons, including malfunctioning ignition systems, fuel supply problems, dirty air filters, and damaged blowers or thermostats.
Malfunctioning Furnace? It Could Be Your Furnace Limit Switch
You may need to do some analysis to resolve the issue. You may also need some tools to repair the furnace if the Dometic RV does not catch fire.
There are some typical signs that your Dometic RV may not light up. Some of them are given below:
If you see any of these symptoms, it is important to evaluate them first and take the appropriate precautions to prevent further damage to the oven.
