Carrier Heat Pump does not run
I have two Carrier heat pumps (Clipper models mfg'd Apr 1984 - round cylinder shape)
Downstairs unit which is linked with a Carrier oil furnace blew a ceramite starter capacitor and tripped off the indoor circuit breaker at the panel box.
I swapped the capacitor and starter from my other functioning outdoor unit into the damaged unit, reset the indoor breaker and turned the outdoor breaker switch back on at the unit. Nothing happens, no fan, no compressor sounds and the indoor fan runs at the furnace.
I did not set the pump to heat to see if that cycle works. I'll try that next. Though my oil furnace (supplemental heat on thermostat) ran over the winter while the heat pump did not since the starter was fried I guess. i replaced the motor on one of my units 2 years ago. Don't know which unit at this point. Could this be a thermostat or worse?
A friend that repairs central ac units and pumps said replacing ac units can be expensive and a real hassle. If I need a new exchanger inside because they have to be bigger now since they may not fit the existing ductwork configuration.
