How to Fix / Troubleshooting
Safety First: Turn OFF the breaker before inspecting wiring. Do not strike the disposal hard; this can damage the housing.
- Step 1 – Check plug and outlet: If corded, ensure the plug is fully inserted and the outlet is not loose. Replace a worn outlet.
- Step 2 – Inspect wiring compartment: Remove the wiring cover on the disposal and verify that all wire nuts are tight and no copper is exposed.
- Step 3 – Test wall switch: Replace the wall switch if it feels loose, crackles, or fails intermittently.
- Step 4 – Evaluate internal fault: If wiring and switch are sound but tapping the unit affects operation, internal motor connections may be failing. Replace the disposal.
