Frequently Asked Questions

Will this thermostat work with my Atwood furnace?

Yes, this Dometic thermostat is designed to replace thermostats in both Atwood and Dometic branded RV furnaces. Since Dometic acquired Atwood, many parts are cross-compatible. Verify your current thermostat wiring matches before installation.

Does this control air conditioning or just heat?

This is a heat-only thermostat designed specifically for furnace control. It does not control air conditioning systems. If you need heating and cooling control, you'll need a different thermostat model with dual functionality.

How do I know if my thermostat needs replacing?

Common signs include the furnace not responding to temperature changes, inconsistent heating cycles, the furnace running continuously, or no response when adjusting the dial. If your furnace blower works but won't ignite, the thermostat is often the culprit.

Is this difficult to install myself?

Most RV owners can replace a thermostat with basic tools and electrical knowledge. You'll need to turn off power, remove the old unit, match the wire connections, and mount the new thermostat. Always follow proper safety procedures when working with RV electrical systems.
