Sounds like you either have control box or thermostat issues. I've had a couple get "confused" and had to be replaced. In our Forester, the AC had erratic behavior and couldn't decide what to do. Replaced control box and t-stat in it. In our Silverback, recently replaced the control box as it go to clicking a bunch like it couldn't decide what to do. Replaced, now all works fine, for now.

At least in Heaven, RVs will be perfect, and I won't have to keep fixing them.
