Many RVs have old style thermostats installed in them, meaning the temperature needs to be controlled manually. That is why many RV owners are opting for an RV thermostat replacement to update their system and install a digital thermostat.
Many older RV units with the older style thermostats only control the furnace and the air conditioner controls are on the outside of the unit. Newer thermostat models today will do both the furnace and air conditioner.
When doing an RV thermostat replacement, the first thing you need to do is make sure the new thermostat will fit on the wall where the old one is installed. Newer style RV thermometers are wider, however, sometimes using a residential thermostat is better for an RV thermostat replacement because of the size. The only thing is for older units you will not have to hook of wires for the AC controls.
The next step of your RV thermostat replacement is to disconnect the RV’s battery to ensure there is no power going to the old thermostat. Unscrew the old thermostat and you will see two wires that may be soldered on to the unit. Clip off the wires from the old unit and be careful not to let the wires fall back into the wall. Lost wires inside a wall is one of the worst things to deal with during an RV thermostat replacement.
Strip the ends of the wires and put the fan and the heater wires in the appropriate connections. Check your owner’s manual for the RV to determine the best configuration for the new thermostat. Attach the plate to the wall, add batteries to the new thermostat and lock it in place. Program the new unit and your RV thermostat replacement is complete.
