Step 1: Gather the Necessary Tools and Materials

Before you start the replacement process, gather the following tools and materials:

  • New RV thermostat (compatible with your RV’s heating and cooling system)
  • Screwdriver set
  • Electrical tape
  • Wire connectors
  • Wire strippers
  • Voltage tester
  • Pen and paper (for noting wire connections)

Step 2: Turn off Power and Disconnect Existing Thermostat

To ensure safety during the replacement process, it’s crucial to turn off the power to your RV’s HVAC system.

Locate the circuit breaker or fuse box and switch off the power supply connected to the thermostat.

Next, carefully remove the cover of your existing thermostat.

Using a voltage tester, confirm that there is no electrical current running through the wires.

Once confirmed, disconnect the wires from the thermostat terminals.

Make a note of the wire connections for future reference.

Step 3: Remove the Old Thermostat

With the wires disconnected, remove the old thermostat from its mounting bracket or wall plate.

Depending on the model, you may need to unscrew the thermostat or release it from mounting clips.

Step 4: Install the New Thermostat

Follow these steps to install your new thermostat:

  1. Mount the new thermostat onto the wall plate or bracket, ensuring it is level and securely attached.
  2. Carefully connect the wires to the corresponding terminals on the new thermostat. Consult the manufacturer’s instructions or refer to the notes you made during wire disconnection.
  3. Once all wires are connected, use wire connectors to secure the connections and prevent any loose or exposed wiring.
  4. Double-check all connections to ensure they are secure and properly attached.

Step 5: Test the New Thermostat

Before restoring power to the RV’s HVAC system, perform a quick test to ensure the new thermostat is functioning correctly.

Set the desired temperature and observe whether the HVAC system responds accordingly.

If the HVAC system doesn’t activate or exhibits any issues, double-check the wire connections and consult the thermostat’s user manual for troubleshooting steps.

Step 6: Restore Power and Finalize Installation

Once you have confirmed that the new thermostat is working as intended, it’s time to restore power to your RV’s HVAC system.

Return to the circuit breaker or fuse box and switch on the power supply for the thermostat.

Finally, replace the thermostat cover, ensuring it is securely in place, and enjoy the newfound control over your RV’s temperature.
