Possible Causes

Extended run time under heavy load, Jammed or partially jammed rotor, Failing motor windings, Blocked ventilation around motor housing

How to Fix / Troubleshooting

Safety First: Immediately turn OFF the disposal and disconnect power. Do not continue to run a unit that smells like burning insulation.

  • Step 1 – Allow cooling: Let the unit cool for at least 30 minutes before touching the housing.
  • Step 2 – Check for jams: Use the bottom hex socket to rotate the motor shaft and ensure the grind plate moves freely. Clear any obstructions from the chamber with tongs.
  • Step 3 – Inspect ventilation: Ensure the area around the motor housing is not packed with insulation or stored items that trap heat.
  • Step 4 – Test briefly: Restore power and run the unit with cold water for only a few seconds. If the burning smell returns quickly or the unit trips the overload, the motor windings are likely damaged.
  • Next step: Replace the disposal. Internal motor overheating damage is not repairable in the field.
