Coleman RV Air Conditioner Thermostats

10 products

When a Coleman Mach air conditioner stops responding to temperature changes or won't cycle on, the thermostat or control box is a common place to start the diagnosis. Coleman Mach thermostats and control components are series-specific, so confirming your existing part numbers before ordering is an important first step.

Our selection covers the full range of Coleman Mach thermostat options, including analog, digital, WiFi, and Bluetooth wall thermostats, multizone and zone control thermostats for multi-unit setups, ceiling assembly thermostat controls, control box assemblies for cool-only and heat pump configurations, room sensors for zoned systems, and a non-ducted ceiling assembly plenum. The AP Products Smart Thermostat is also available as a compatible upgrade option that works across Coleman, Dometic, Furrion, and GE Appliances systems.

Confirm your existing thermostat part number and AC model before ordering, as wall and ceiling-mount versions are not interchangeable.

Which Coleman Mach air conditioners are these thermostats compatible with?

The thermostats in this collection cover Coleman-Mach RV air conditioners running the RV Comfort HC, HP, and ZC control systems, including ducted and non-ducted ceiling assembly setups. Always confirm your existing thermostat part number and AC model before ordering, since wall and ceiling-mount versions are not interchangeable. If your unit uses a ducted ceiling assembly, the matching control board lives in the Coleman ducted ceiling assembly or Coleman Power Saver HP ducted ceiling assembly collections.

What is the difference between the RV Comfort HC and RV Comfort ZC thermostat?

The RV Comfort HC is a heat/cool analog wall thermostat used with standard Coleman-Mach AC units and gas furnaces. The RV Comfort ZC is a digital zone control thermostat designed for systems with a heat pump or multiple zones. The boards inside the ceiling assembly must match the thermostat type, so check both the wall unit label and the ceiling assembly part number before ordering a replacement.

How do I know if my Coleman RV thermostat needs replacement?

Common failure signs include a blank display, unresponsive buttons, the AC or furnace not cycling on command, or temperature readings that drift far from actual cabin temperature. Before replacing the thermostat, verify 12V power at the wiring harness and inspect the control board in the ceiling assembly, since a failed board can mimic thermostat symptoms. For broader 12V troubleshooting parts, see our RV electronics collection.

Can I install a Coleman Mach thermostat myself?

Yes. Most Coleman-Mach thermostat swaps take 20 to 30 minutes with a Phillips screwdriver, once the RV's 12V power is disconnected at the battery. Label each wire as you remove it from the old thermostat, then match the lead colors to the same terminals on the new unit. If you are pairing the thermostat with a non-ducted setup, confirm the ceiling board matches by checking the non-ducted ceiling assembly with wall thermostat collection for the correct board pairing.
