How to Fix / Troubleshooting

Safety first: Turn OFF the disposal and shut OFF the breaker immediately if you smell burning. Do not continue to run the unit.

  • Allow cooling: Let the American Standard disposal cool for at least 20 minutes.
  • Inspect chamber: With power OFF, look for plastic utensils, rubber bands, or other non-food items and remove them with tongs.
  • Check ventilation: Ensure items stored under the sink are not pressed tightly against the motor housing, blocking airflow.
  • Test briefly: Restore power and run the unit with water for a few seconds. If the burning smell returns quickly or the unit sounds strained, the motor may be failing and the disposal should be replaced.
