I seem to have a problem with my home heat/ac/thermostat that I'm not sure what it could be. The home is a single-wide trailer with central ac (Outdoor unit) and a heat pump inside the house. Yesterday the area where the heat pump is made some loud thumping noises which eventually stopped and the heat kept going. When I got home last night the heat was running and I flipped it off. Now it seems to be dead. As of right now, the thermostat won't turn on the heat/ac/fan at all. I pulled the panelling from the wall and checked the heat pump and by flipping the blower switch from auto to on the blower fires up and I get air flowing through the vents. I don't have a terminal tester handy right now so i'm not sure if the thermostat is fault. The thermostat is a White-Rodgers model 1F56-444 and has RH, RC, Y, and W connectors. Is there a way to manually jump the power to see if its the thermostat thats faulty? I can't afford a new heat pump and i'm hoping that this is just an old thermostat going bad issue. Any help would be appreciated.
