Frequently Asked Questions

How do I know if my thermostat control module is failing?

Common signs include: the HVAC system won't turn on, temperature adjustments have no effect, the unit cycles on and off repeatedly, or the display is unresponsive. This module controls all those functions, so failure in any area points to a replacement need.

Will this work with my specific Dometic model?

This AS/MH/12 module fits Dometic systems using that designation. Check your existing thermostat or HVAC unit documentation to confirm compatibility. Our expert support team can verify your model if you're unsure.

Is installation difficult?

No—this is a plug-and-play replacement. Disconnect the old module from its wiring harness and plug in the new one. Most RV owners complete the swap in under 10 minutes. Always disconnect power before working on HVAC components.
