The compressor shut off after a few hours this time. Restarted the A/C several times, ran the fan on high, turned the thermostat down - couldn't get it to run more than 2 minutes. Disconnected the freeze sensor, same result. So, I ran the heat pump for about 2 minutes. It did not stop when it reached the set temperature, so I bumped it down more and I finally had to shut it off. After that, the A/C worked fine. I don't see any freezing going on - but there does seem to be a thermostat issue of sorts. I'll probably call Thor and Dometic tomorrow to see whether they can shed light on this.
