The capacitor in most all of the ac’s here in the villages are dual capacitors that work with both the fan and compressor. Depending on what section of the capacitor failed would determine if the fan, compressor, or both would not run.
The humming is the motor or compressor trying to run and going off on internal safety. When it cools down it will try again.

I hear what your saying but if fan won’t run, it’s the high voltage side of the capacitor, then when the voltage surges then the low voltage will kick in & keep the air conditioner running. Yes, some have 2 capacitors but I bet you 85 to 90% of the homes have only 1 capacitor in their air conditioner. I would still bet it’s the capacitor that’s bad. For 20 or $30. I would change the capacitor. Surely there’s someone that can pull 3 or 4 wires off the capacitor & discharge it & put new one in. Maybe you’re right about dual capacitors but I know 4 people that changed their bad capacitor & all 4 had 1 capacitor. Then again maybe I just got lucky & talked to the ones that had only one.
