Gearing up for an epic road trip and finding yourself concerned that your RV thermostat may be bad? 

There are countless reasons why your thermostat could be having trouble. Perhaps the batteries are dead, maybe a wire has become disconnected, or it could simply be time to change your thermostat altogether.

If you are unsure how to tell if your RV thermostat is in need of repair or replacement, keep reading to learn what to do if you suspect your RV thermostat is bad.



3 Ways To Tell if an RV Thermostat Is Bad

How can you tell for certain that your RV thermostat is bad? Here are three signs that your RV thermostat needs to be replaced.

Your RV Thermostat is Unresponsive

If the screen is black or unresponsive, chances are your RV thermostat is bad. 

But before simply throwing the thermostat out, first, check to make sure the issue isn’t just due to dead batteries. If the RV thermostat is still unresponsive after a battery change, you need a new one.

Your RV Thermostat Setting Doesn’t Align With the Actual Temperature

If you’re shivering or melting in your RV, you need to take a look at the thermostat settings. If the RV thermostat says that your RV is a normal temperature but you’re feeling either too hot or too cold, your thermostat could be broken.

The Heat or A/C Won’t Switch Off or On

If your RV thermostat won’t let you switch the A/C or heating off or on, your thermostat likely has a problem. Bad RV thermostats will often blast the heat or A/C nonstop despite your best attempts at switching it off.

How To Replace a Bad RV Thermostat

If you have concluded that your RV thermostat is bad and in need of replacement, here are five steps for replacing your thermostat. 

  1. Choose a good RV thermostat: you should choose an RV thermostat that is highly rated and works with your specific RV model. Make sure your new thermostat is the correct size to snugly replace your old RV thermostat.
  2. Shut off your RV’s power supply: this is to ensure that you can safely replace the bad thermostat without risk of injuring yourself. 
  3. If you still have the manual for your bad thermostat, read the instructions on how to remove the thermostat from the wall.
  4. Once you’ve removed the bad thermostat, take a quick photo of the wall mount and wires for future reference.
  5. Take your new RV thermostat and follow the instructions for mounting and installing it. Using your reference photo and the new RV thermostat manual, you should be able to install your new thermostat safely and easily.
