The other day my thermostat for zone one was showing the inside temp at 32 degrees F. Of course this kept the A/C from working, thank God for the rear unit. Then about 12 hours it started to read correctly. I feel the thermostat is going bad(on a 5 month old trailer?). The thermistor is in the thermostat for zone one, zone 2 is in the bedroom. Anyone have or seen this before. Dometic has NOT returned any email attempts. I will be getting my Dometic ID number next month after I go to a school put on by them and since it is working for now will bring it up at the school. So any help before I go would be nice Thanks
