Whirlpool garbage disposal runs but produces a loud rattling noise.

Safety first: Turn off the switch, unplug the unit, and shut off the breaker.

• Inspect chamber: Shine a light into the disposal and remove any loose objects with tongs.
• Check impeller lugs: Gently move the impeller lugs with a wooden spoon; they should pivot but not be excessively loose or broken.
• Inspect splash guard: Replace a torn or missing Whirlpool splash guard to prevent future objects from falling in.
• Verify mounting: Ensure the mounting ring and sink flange are tight and not rattling.
• If rattling persists with an empty chamber: Internal components may be damaged; replacement of the disposal is recommended.
