Garbage Disposal Hums But Doesn't Grind
You'll know your disposal is jammed or clogged when the motor hums but the disposal doesn't run, the disposal is overly noisy, or it runs and then stops before you turn it off.


The problem is often a piece of bone, a fruit pit, or the like stuck between an impeller blade and the drain hole. Don't continue to run the disposal when it's jammed; this can burn out the motor.

To clear a jammed disposal:

1) Unplug the unit, and check the instructions in your owner's manual.


2) Under the sink, look at the bottom of the disposal for a hex-shaped hole. If you see one, look for a hex wrench that fits the hole (it's often attached to the disposal).

Fit the hex wrench into the hole, and force it back and forth in both directions to free the impellers. Note: Some models have a reversing switch that accomplishes the same action.

4) If something has been put in the disposal that shouldn't have been—such as metal, rubber, glass objects, or fibrous food waste such as artichoke leaves or banana peels—use tongs or pliers to pull the material out. Never use your hand.


5) If this fails, call a
repairperson.
