    ONLY 2 things will cause this on your Dometic system
    1. The ZONE on your tstat is NOT set to the one on the affected AC unit. Make sure you can see BOTH Zone 1 and 2. 2001, you may have the original 4 button tstat instead of the updated 5 button. IF you have a ZONE button you have the 5 button. IF you have NO Zone button you have the original 4 button. If you have the 4 button, do you know how to change Zones?
    2. Your upper main control board is bad, it will need replaced. Doug
  • The relay that is powering the fan has the contacts welded together. Get another relay.

    Better if you can post the DuoTherm model, and that of the Thermostat as well.

  • What brand is your AC?..and your coach...This happened to my wireless carrier unit and I found out that it didn't like the wifi hot spot close to it...Once I moved it...it resolved itself..
  • It is set on auto, even when I turn the termostat off the fan runs, I have to click the breaker to get it to stop. Thought it might be thermostat.
  • Check thermostat, make sure it's set to Auto and not to On.
