Tappan heat pump model: C3BA-030C-B
I cannot find much info for it online, tried to find a manual to troubleshoot. I reset the ignition module and the exhaust blower turned on for a few minutes then goes off. While it is on a here clicks every several seconds. I do not see any flame in the window and the main blower never turns on. The main blower works when I select manual on the thermostat. Fuse is good, circuit breaker is on, gas valve is open. What do I need to check?
