RV furnace runs with thermostat off – What’s the problem?

When it comes to dealing with RV furnaces, many RVers may experience a problem where their furnace is running even when the thermostat is set to off. This can be an annoyance because it means that you are wasting energy and money on something that should not be running in the first place. In this article, we will discuss what could be causing this and how to fix the problem.

How Does an RV Propane Furnace Work?

RV propane furnaces are designed to provide heat and hot water in an RV. When the thermostat is set to a certain temperature, it will trigger the furnace to turn on and begin heating. The furnace will then continue running until it reaches the desired temperature or when the thermostat is turned off.

What Could Be Causing Your RV Furnace To Run With The Thermostat Off?

There are several possible reasons why your RV furnace may be running with the thermostat off. The most common cause is a bad thermostat or wiring issue. If the wiring or the thermostat is not working properly, it can cause your furnace to run even when it is set to “off”.

Another potential issue could be debris blocking the air flow from entering or exiting the furnace, which would also cause it to run without being turned on.

Finally, there could be an issue with your propane tank that causes too much pressure in the lines and pushes gas into the system without you knowing.

If you’re looking to shut off your thermostat, make sure it has an “OFF” switch – otherwise it could just be in the lowest heat setting. Test this theory by disconnecting its wires and see if that shuts down the operation; a freeze protection mode may also be enabled on the heater itself. For peace of mind when away from home, remember to turn off the breaker which runs power through.

How to Fix the Problem

The best way to fix this problem is to troubleshoot it yourself. First, check the wiring of your thermostat and make sure that there are no loose connections or wires that could be causing an issue. You can also visually inspect the furnace itself for any signs of debris blocking the air flow or a malfunctioning part such as a valve, motor, or fan.

If you find nothing wrong with these components then you should contact a qualified technician who can diagnose and repair whatever is causing your RV furnace to run with the thermostat off.

It is important to remember that if you do not feel comfortable doing any of these repairs yourself, it is always best to call a professional. They will have the experience and knowledge to accurately diagnose and repair whatever is causing your RV furnace to run with the thermostat off. It is also important to make sure that you always follow safety precautions when dealing with any kind of gas appliance, as it can be dangerous if misused.

In conclusion, an RV furnace running when the thermostat is set to “off” can be a major hassle and waste of energy. To fix this problem, first check the wiring of your thermostat then visually inspect the furnace itself for any debris or issues that may be causing it to run without being turned on. If you are unable or uncomfortable doing these repairs yourself, contact a qualified technician who can help diagnose and repair whatever is causing your RV furnace to run with the thermostat off. Remember to always follow safety precautions when dealing with any type of gas appliance.
