What to do if disposal hums but does not grind?
Garbage Disposal
If the garbage disposal won't turn on but the motor makes a humming sound when you flip the switch, it indicates that the inner flywheel is jammed. Usually, this causes the appliance's reset button to pop or the circuit breaker to trip very quickly. This is not a situation you want to continue for very long, as it can burn out the disposer's motor unless the reset button or circuit breaker shuts things off.
The problem is almost always the result of food or a foreign object being lodged between the impeller(s) and the shredder ring inside the disposal.
Reminder: Never put your hand down into the garbage disposal hopper (grinding chamber).
1. Turn off power to the garbage disposal at the electrical service panel by shutting off the breaker controlling the circuit. Also, turn off the wall switch controlling the disposal.
2. Take the offset wrench that came with the disposal unit and insert it into the flywheel turning hole in the bottom of the unit. If you don't have the wrench, you can pick one up from the hardware store that sells your garbage disposal. A large Allen (hex) wrench may also work.
3. Once the wrench is inserted, turn it clockwise to dislodge the stuck impeller or flywheel. When it dislodges, you'll feel the flywheel turn freely.
4. Another approach is to use a wooden spoon handle or similar wooden object to reach down into the disposal through the drain opening, using it as a lever to free the stuck flywheel. If you're successful, you'll feel the flywheel begin to turn freely.
5. Use a flashlight to look down into the disposal. If you see the object that caused the jam (wayward meat bones and pieces of dinnerware are common culprits), use pliers to remove the foreign object.
6. Once the flywheel is freed, turn the power back on at the main service panel but don't turn on the disposal yet.
7. Go back to the disposal and press the red reset button on the bottom.
8. Put some tap water into the disposal and quickly flip the switch on and off for a short burst. Turn on and off again quickly. This should spin the flywheel and cause any dislodged debris to be washed down the drain.
