If you’ve been having trouble trying to keep the inside of your rig warm for some time now, it might be a problem with your thermostat. If yours is already a few years old, it might be time to spring for a replacement. If you’ve always used an analog thermostat, then better to go with a digital one. Not entirely sure how to install it? Here’s a handy list of steps to you guide you through it:
-
Toss the old thermostat.
Disconnect your RV battery first before you unscrew the thermostat from where it’s mounted. Make sure you note which wires connect to where. Take a photo so you won’t forget. You can also use a volt tester to help you figure out those wires, as DoItYourSelf recommends.
-
Check out the wires.
Review the wiring of the new thermostat and compare it with your old one. You could also follow the instruction manual for some help on where to connect those wires. In many cases, the red wire usually connects with the red wire on your thermostat mount, so it’s not that hard to figure out.
-
Connect the new thermostat.
When you’re finally done with the wires and you’re sure you’ve got them all connected just right—don’t forget to test this out—then screw the thermostat back in place. Once that’s done, there’s only one thing left to do: reconnect the RV battery.
Installing a new digital thermostat in your RV is sure to guarantee better results and keep you and your rig warmer. So if you think your temperature controls are starting to go on the blink and the problem isn’t caused by any other part in your RV, then start taking a closer look at your thermostat. It might just be the perfect time for you to start looking for a replacement.
