I have a 2015 3610 rl with Legacy package, 2 Dometic A/c units and one ccc2 thermostat. Most recent trip, I noticed that the bedroom A/C wasn't cycling off when the temp set point was reached. Pushing the "inside temp" button showed 69 and I raised the set point up to 90 and it still wouldn't shut off. Thermostat was set to COOL and fan on AUTO. The only way to shut it down was to set the thermostat to OFF for zone 2. I opened the 50 amp breaker at the power pedestal and removed and unplugged the thermostat, hoping a power cycle would straighten it out. No change. The other thing I noticed was that when turned ON, the bedroom A/C would start running immediately, instead of the usual 10 or so second delay.

Anyone had this issue and found the solution?

Thanks,

Andy
