There could be several reasons for this -
Some motors have an oil fitting with a tiny cap, try putting oil and rotating by hand with the unit off (unplugged). Also you can add oil at the shaft where it meets the motor.
Some motors have a starting capacitor which might need to be changed.
Motor bearings may be shot.
But normally, oil in the right spot will do the trick. Use 3 in 1, not WD-40.

Good luck.

Sounds like the motor has gone bad.

Blower won't run


usually a "humming motor" indicates either a bad capacitor or a defective motor. With the power off try to spin the blower wheel...it should spin freely. If it is tight or wont spin and there are no obstructions stopping it (like an air filter sucked into blower or other debris) then the motor most likely is seized. If the blower wheel spins free then you may have a bad capacitor. Keep in mind, just because the blower spins easy doesn't mean the motor is good. I have had motors that are defective that dont seize up but most of the time the blower wheel will not spin free if the motor fails.

The disposal only hums. I can turn the blades inside so there is no food stuck. I know there is a reset button but cant locate it.


I had the same problem, it was just humming, then after a few second the on board circuit breaker would cut out. After a little while I could hit the reset button and it would just hum again.

It turns out that the base of the disposal was jammed. There are 2 blades on the top that should spin freely, but the base plate that the blades are attached to also spins. In fact, that's what the motor drives. The two blades on top are not powered, they just flip back and forth as the base spins. So get a broom handle or a strong wooden spoon, stick it down in there, and try to pry the base plate free so it spins. That should do it.

My blower motor will not start. it hums and gets very hot. i can spin the wheel with no resistance gmp075-4


Assuming you are spinning it when the motor is humming, if the motor runs after spinning it it could be the run capacitor (replace) or open/broken start winding in motor(need new motor). Humming should indicate the motor is getting proper voltage. If motor does not try to run by spinning then open run winding in motor (replace motor).

Hums with no spin, then turns off


Turn off and unplug. Reach in and try to spin the drum by hand . if it won't turn the support rollers are probably bad and need replaced. If it turns then plug it in and try to turn it on. If it turns on and spins then the motor may be going bad. If it won't spin the motor or capacitor may need replacing. Good luck and let me know if I can be of any help. Please rate me so I know how I'm doing. Thanks.
