Possible Causes

Ventilation blocked around motor housing, Prolonged grinding of tough materials, Partially jammed grind plate increasing load, Failing motor with increased internal friction

How to Fix / Troubleshooting

Safety first: Turn off power and allow the unit to cool completely before touching.

  • Improve ventilation: Ensure items stored under the sink are not packed tightly around the disposal, restricting airflow.
  • Clear jams: Use the hex wrench to free the grind plate and remove any obstructions.
  • Adjust usage: Avoid long continuous grinding of hard materials. Use shorter bursts with cool-down periods.
  • If overheating persists: The motor may be failing. Replace the disposal.
