Garbage disposal is unusually loud compared to normal operation

Safety first: Turn OFF power before touching the unit.

• Step 1 – Check for loose mounting: Tighten the mounting ring screws and ensure the disposal is fully locked into the mounting tabs.
• Step 2 – Inspect splash guard: Verify the rubber splash guard/baffle is properly seated in the sink opening. Replace if torn or missing; this significantly reduces noise.
• Step 3 – Listen for bearing noise: With water running and the disposal on, listen for a high-pitched whine or grinding from the motor area (do not touch). Persistent bearing noise indicates motor wear and the unit should be replaced.
• Step 4 – Isolate sink vibration: Add foam or rubber pads between the sink and countertop clips if the sink itself is vibrating excessively.

Warning: Do not attempt to lubricate the disposal; it is a sealed unit and added oils can cause clogs.
