I'm suspecting you need to reset the thermostat. On the older Dometic thermostats, the reset was pushing both the up and down arrows at the same time. This also allows access to some settings - like going down to 1 deg swings instead of 2 deg swings (you don't want to do that). My selling dealer said to reset the thermostat at the beginning of every trip. I don't do that, but that is my go to if heater/Cool Cat aren't working right. Also, unsaid by Dometic is that having the fan in any mode except "Au" (auto) will yield unpredictable results. Found that one the hard way, and considerable reading.
