    Don't leave it on and humming like that. It is stuck, and could overheat. It may be stuck because of worn out bearings, or because there are internal shorts in the windings that are reducing the overall torque, or both.

    Time to replace the fan, I'm afraid.

    could the problem be the capacitor?
    single phase induction motors are not self starting, so if the capacitor is not working, the motor won't start running, am i wrong?

    Interesting. Does the fan run if you start it by spinning it by hand? Do the fan blades seem to spin smoothly (no bearing problems)?
