Possible Causes
Loose mounting ring allowing slight movement, Loose internal wire connection, Worn motor brushes (on brush-type models), Misaligned sink flange causing rotor drag
How to Fix / Troubleshooting
Safety First: Turn OFF power before tightening mounts or opening wiring compartments.
- Step 1 – Tighten mounting assembly: Ensure the disposal is fully locked into the mounting ring and that all mounting screws are snug.
- Step 2 – Inspect wiring connections: With power OFF, open the wiring compartment and verify all wire nuts are tight and no wires are pulling loose when the unit is moved.
- Step 3 – Check for rubbing: Listen for scraping sounds that might indicate the grind plate is contacting the housing due to misalignment.
- If symptoms persist: Internal motor or bearing wear may be present; replacement of the disposal is recommended.
