Thermostat clicking heat not working
I just bought a 2016 north point 375bfhs. The first time we go to use heat it cycles on and off on electric heat. The heat pump turns on then the thermostat clicks rapidly then turns off the heat. This cycles every 10-15 seconds. If I turn to gas heat everything runs fine. Also when the heat pump is on the gas furnace runs with no ignition of propane, is this normal. The heat pump worked fine last weekend but now itís acting up. Any help is appreciated. What to troubleshoot?
