Possible Causes
Severe jam in grinding chamber, Foreign object wedged at motor shaft, Bent grind plate, Failed start winding in motor
How to Fix / Troubleshooting
Safety First: Turn OFF power and do not repeatedly reset the overload while the rotor is locked; this can damage the motor.
- Step 1 – Manually free the rotor: Insert a 1/4" Allen wrench into the bottom hex socket and work it back and forth firmly to break free any jam. You should feel the plate begin to rotate.
- Step 2 – Remove debris: From above, use tongs to remove any large bones, utensils, or other objects.
- Step 3 – Reset overload: Once the rotor turns freely by hand, press the reset button until it clicks.
- Step 4 – Test with water: Run cold water and switch the unit ON. If it still hums and trips, the motor start winding or capacitor (if equipped) may have failed.
- Next step: For AmazonCommercial disposals, motor electrical components are not typically user-serviceable; replace the unit if the rotor is free but the motor cannot start under load.
