I have a ceiling fan that hums badly. Is not dimmed is running at full
speed or one notch down with the pull chain. Is not a 120Hz buzz but a
slow
hum modulated by the blade position. In other words the hum changes
cyclically around the blade circle. It is not mechanical because it stop
immediately after cutting power.

Any idea on what to look for when I get it down?

Thanks

Sounds like the motor has a problem.

Have you checked all of the wiring? Especially if the motor is grounded?
