Garbage disposal vibrates and makes noise only at certain speeds or when starting/stopping.

Safety first: Turn off power before touching the unit or plumbing.

• Step 1 – Check for debris: Inspect and clear the chamber of any loose objects.
• Step 2 – Tighten mounting hardware: Ensure the mounting ring and any support brackets are tight.
• Step 3 – Secure drain line: Add clamps or supports to flexible drain hoses to reduce vibration transfer.
• Step 4 – Test: Run the disposal and observe. If noise occurs only briefly at startup and is minor, it may be normal. Persistent or severe noise suggests internal wear and may require replacement.
