Do RV Thermostats Go Bad? Troubleshooting Process
There are a few ways to test your RV thermostat to see if it’s working properly.
- The first way is to simply take a look at the display. If the display is blank or shows an error message, then the thermostat is probably not working correctly.
- To test your RV thermostat is to turn on all the lights in your RV, and then turn on the furnace. If the furnace doesn’t come on, that means the thermostat is probably bad.
- One more way to test your is to put an ice cube on the “TH” terminal and see if the furnace comes on. If it does, that means the thermostat is working properly.
- Another way to test your RV thermostat is to set the temperature to a specific setting and then see if the heating or cooling system turns on as it should.
- If you have an infrared thermometer, you can also use this to test your RV thermostat. Simply point the thermometer at the thermostat and see what temperature it displays.

- Another cause of a bad RV thermostat is moisture damage. This can happen if there’s a leak in the cooling system or if the RV is stored in a humid environment.
- Yet another cause of a bad RV thermostat is voltage surges. These can damage the internal components of the thermostat and cause it to malfunction.
- One last cause of a bad RV thermostat is physical damage. This can happen if the thermostat is dropped or hit.
How To Replace RV Thermostat?
Replacing your RV thermostat is a pretty simple process.
- The first thing you’ll need to do is turn off the power to the RV’s heating and cooling system.
- Next, remove the old thermostat from the wall.
- Then, take the new thermostat and mount it in the same location as the old one.
- Finally, connect the wires from the heating and cooling system to the new thermostat.
- Once everything is connected, turn on the power to the system and test it out.
Tips For Using Your RV Thermostat Safely and Effectively
- One tip is to make sure that you clean your RV thermostat regularly. This will help to prevent dirt and dust buildup, which can lead to problems.

FAQS- RV Thermostat Troubleshooting
How do I know if my thermostat is malfunctioning?
There are a few signs that can indicate that your RV thermostat is malfunctioning.
- One sign is if the temperature in your RV fluctuates frequently.
- And one last sign is if your RV feels too hot or too cold even when the thermostat is set to the correct temperature.
- If you notice any of these signs, then it’s time to replace your RV thermostat.
How do you test RV thermostat wires?
To test the wires, you’ll need a multimeter. First, set the multimeter to the “resistance” setting. Then, touch one of the leads to one of the thermostat wires and touch the other lead to the metal part of the thermostat. If the multimeter beeps or shows a reading of zero, then the wire is good.
If the multimeter doesn’t beep or show a reading of zero, then the wire is bad and needs to be replaced.
Where does the RV thermostat get power from?
The RV thermostat gets power from the RV’s battery.
Can I replace my RV thermostat with any thermostat?
No, you’ll need to make sure that you get a thermostat that’s specifically designed for use in an RV.
How often should I replace my RV thermostat?
It’s generally recommended that you replace your RV thermostat every five years or so.
If your RV thermostat isn’t working, it is likely one of four problems: the wiring, the fuse, the thermostat itself, or the control panel.
- Wiring: To test if the problem is with the wiring, you’ll need to check for voltage at the thermostat. If there’s no voltage coming from the furnace when you turn on the heat, then there’s a good chance that it’s a wiring issue.
- Thermostat itself: If you think your RV thermostat might be bad, remove it and take it with you to an RV store so they can test it for you.
- Control panel: If your RV has a digital thermostat (as opposed to an analog one), make sure that it is set to “cool” mode before testing it.
Finally, Testing an RV thermostat is relatively simple and only takes a few minutes. By following these steps, you can quickly determine whether or not your RV thermostat is bad and needs to be replaced.
