Carrier heat pump, outdoor unit fan will not rotate and hum comes from compressor(?).
Asked Jun 18, 2008, 01:08 PM
This relates to the outside carrier heat pump unit. Symptoms are: the unit is receiving the signal to turn on from the inside thermostat. The contactor clicks closed (audible). There is a humming sound. I think in is the compressor. The large fan on the outside unit does not rotate. I do give the unit enough time for any possible delays that might be in effect. Any help would greatly be appreciated. Thank you very much.
