Lennox Condenser Hums


Hello. The A/C has been down all day, and when I got home from work, I went outside and the condenser was humming, but nothing was moving. Any ideas on where to start? Someone mentioned to look at the start capacitor. Any other ideas?
The fan works. The condenser was hot to the touch on the top of the unit. It's not off at the breaker.

thanks

If the fan spins freely with power removed, replace the run capacitor for the condenser fan motor.
(Probably a dual capacitor)
