Microwave makes a rattling or scraping noise from the turntable area during operation.

Safety: Unplug the microwave before cleaning or inspecting the turntable mechanism.

Steps to fix rattling turntable:

• 1. Remove and clean: Take out the glass tray and roller ring. Clean both and the cavity floor thoroughly.
• 2. Inspect roller ring: Check for flat spots on the wheels or cracks in the ring. Replace if damaged.
• 3. Check tray fit: Ensure the glass tray sits properly on the coupler and roller ring without wobbling.
• 4. Inspect coupler: Verify the coupler is fully seated on the motor shaft and not cracked.
• 5. Test: Reassemble and run with a light load to confirm the noise is gone.
