Possible Causes
Loose internal wire connection, Damaged insulation inside terminal box, Failing motor windings, Moisture intrusion into electrical compartment
How to Fix / Troubleshooting
Safety First: Turn OFF the breaker immediately. Do not operate the disposal until inspected.
- Inspect wiring cover: Remove the small wiring cover on the disposal (power OFF) and check for loose or burned wires. Tighten connections if slightly loose.
- Look for burn marks: Any charring or melted insulation indicates serious internal damage.
- Dry moisture: If moisture is present, identify and fix the source of the leak before replacing or re-energizing the unit.
- Replace if arcing persists: Internal arcing is a fire hazard. Replace the Waste Maid disposal rather than attempting internal motor repair.
