I have a dometic air conditioner in our 2015 grand design that runs great until it reaches desired temp. Then it shuts off but fan continues to run, however, as temp goes up it will not restart coolin...
See if the same problem exists when running the AC on high fan, as opposed to low fan OR Auto. I have the same problem, and changed the thermostat. That didn't help. So now we just keep it on High fan with no problems
