Garbage Disposal Humming or Jammed — How to Fix It
A garbage disposal that hums but does not spin is jammed — the motor is getting power but the impeller plate is stuck. This is a 5-minute fix you can do yourself, safely, without a plumber. A disposal that is completely dead usually just needs its reset button.
Safety First
Turn the disposal switch OFF and never put your hand down the disposal. Everything below is done with the power off at the switch (and ideally the breaker).
Free a Jam With the Hex Wrench
Look under the disposal for a hex (Allen) socket in the center of the bottom. Insert the 1/4-inch hex wrench that came with the unit (or a standard one) and crank it back and forth several times. You will feel the jam break free as the plate turns. This clears whatever (a bone, pit, or utensil) locked it.
Remove the Obstruction
With the power off, shine a flashlight down the disposal and remove any visible object with pliers or tongs — never your fingers. Common culprits are fruit pits, bones, glass, and silverware.
Press the Reset Button
A jam usually trips the disposal's overload protector. Press the red reset button on the bottom of the unit. Then turn on the water, flip the switch, and it should spin freely again.
If It Is Completely Dead
No hum at all means no power. Press the reset button first. If still dead, check the wall switch and the breaker. If the reset button will not stay in, let the motor cool for 10 minutes and try again.
