Initial Preparations
Bypassing a Dometic RV thermostat requires careful steps. Start with thorough preparations. This ensures the process is safe and effective.
Powering Down The System
First, turn off the power. This is crucial for safety. Locate the main power switch of your RV. Switch it off. This step prevents electrical shocks and equipment damage.
Next, disconnect the RV from any external power sources. This includes unplugging from shore power. If your RV has a battery disconnect switch, use it. This cuts off the power supply completely.
Accessing The Thermostat
Now, locate the thermostat. It is usually mounted on a wall. Use a screwdriver to remove the cover plate. This exposes the internal components.
Once the cover is off, you will see several wires. These wires connect to the thermostat. They control the heating and cooling system of your RV. Take a picture of the wiring setup. This helps you remember the original configuration.
Label the wires if needed. This ensures you can reconnect them correctly later. Now, you are ready to proceed with bypassing the thermostat.

Bypassing The Thermostat
Bypassing the thermostat in a Dometic RV can be necessary. Sometimes the thermostat fails or doesn’t respond as it should. Knowing how to bypass it can help. This guide will walk you through the process. You’ll find easy steps and alternative methods to try.
Step-by-step Instructions
First, ensure your RV is off. Safety first. Locate the thermostat wires. Usually, they are behind the thermostat panel. Carefully remove the panel. Check the wires. You will see two main wires. These are usually red and white.
