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?

Are you in the right Zone and in the right Mode for the heat pump and for the furnace? Try this take the front of the thermostat off if there is a fuse in it pull the fuse for 30 sec and replace it and see if that helps.
