About this repair:

  • Rated as REALLY EASY

If your garbage disposal is making a loud humming, grinding, or rattling noise, it could be the result of a jammed grinding chamber. Food or other debris can become trapped in the chamber, resulting in the unusual noise. Shut off power to the disposal and visually inspect the sink opening for a jam. You can access the grinding plate with a long object to rotate it, or go through the bottom of the unit with a special offset wrench to turn the plates manually and dislodge the jam. If there is no visible jam, the issue may be the motor or motor start capacitor. The noise could also be the result of a defective grinding plate, grinding ring, or motor assembly. These parts are not usually available as replacements, which means the garbage disposal would need to be replaced.
