Microwave produces rattling or vibration noises from the cabinet during operation.

Safety first: Unplug the microwave before adjusting its position or checking mounting hardware.

Steps:

• Ensure the microwave is level front-to-back and side-to-side; adjust feet or mounting as needed.
• Remove and reseat the glass tray and roller ring.
• If built-in, check that mounting screws are snug but not overtightened.

If rattling persists from inside the cabinet:

• An internal component or duct may be loose; schedule service for internal inspection.
