Another Heat Pump stopped working
Basically everything seemed to be working when I got home. But at some point last night I noticed the air coming out of the vents was not cold. I checked the drain for the unit the basement, it was not draining, but it was not plugged up either. I turned off the power for 10 minutes, turned it back on and it still didn't work. There is no icing on the lines inside or outside. The unit/fan outside is not turning, it is making a humming noise. The fan turns if you push it, so it does not appear the fan motor is locked up. I have called for a technician, but I would like to know the possibilities of what the problem could be. Thanks for any help.

Like said the hmming can mean you are getting 24 V. From there can just be the contactor or the contactor points dont close . Then on to the capacitor. But you said the fan didnt run when you pushed it and calleing for cool so its back to the contactor. have you turned the breakers off and back on??

Well the humming is the compressor running, which is a good thing. If the fan isnt turning with the power on, i would venture to say that its a electrical problem with the fan, perhaps a capacitor or the fan itself is grounded/shorted. Its probably shutting off on a low pressure/high pressure control after a short period of time.
