RV Heat Pump & Gas Heater
My thermostat RV Comfort HP will not let my roof heat pump come on and also when set to Gas heat it will not come on. Could it be the thermostat is bad?

There is a small fuse on the tstat when you remove the cover. Make sure it is good. Does the Roof AC fan come on when you put in Fan only mode? That will help pinpoint a tstat problem. It is RARE for a tstat to be bad. It is usually a 12 volt supply problem. Doug
