Dometic 15K AC not turning on

1yr old trailer and I have been using the AC quite a bit lately as the AC on my house recently went out:)

I turn on the digital thermostat like I always do and can hear the relay in the unit, but it never kicks on. Even in fan mode it wont cycle, just hear the relay.

I tried on both shore power and generator and same thing.

Any ideas? Looking through my stack of manuals it doesn't look like I got one for the AC unit.

  • Here is the unit and thermostat...

    I'll try the reset thanks.

    Checked all my breakers and they all look OK.



  • what thermostat do you have? You can do a reset. For the new CCC thermostat the reset procedure is:
    Make sure the CCC 2 thermostat is in the OFF mode.
    • Simultaneously press the MODE and ZONE buttons. The LCD will display
    “IniT” and all available zones.
    • Release the MODE and ZONE buttons.
    • Press the ON/OFF button to exit system set up.
