How to Fix / Troubleshooting
Safety first: Immediately turn off the wall switch and shut off the breaker. Do not attempt to restart the unit. Ventilate the area.
- Allow cooling: Let the disposal cool completely before touching it. Do not press the reset until it has cooled.
- Inspect for visible damage: Look for melted plastic, burned wiring, or scorch marks around the motor housing and junction box.
- Check for leaks: Determine if water leaks contributed to the failure and correct any plumbing issues.
- Do not reuse: A disposal that has smoked or emitted a strong burning odor has likely suffered irreversible motor damage.
The safe and proper remedy for a burned-out Maxmatic motor is full replacement of the disposal unit and inspection of the electrical circuit.
