Heat pump problem, indoor fan blows in heat but not A/C or "on"
I have a heat pump with indoor air handler and Emergency back up electric heat. All of a sudden the airhandler fan stopped working. After checking fuses, breaker box etc I tried heat just to see and after the wait period the heat came on and so did the blower. I switched back to A/C and after the wait period the outdoor unit started working but airhandler fan still doesn't come on. I figured if Outdoor unit works and indoor unit works in heat that it would have to be the thermostat. well replaced it today and same thing.
Any ideas? This makes no sense to me if not the thermostat.
