Turntable rotates unevenly, wobbles, or makes grinding noises during operation.

Safe to troubleshoot: This is a low-voltage mechanical issue.

• Remove and clean: Take out the glass tray and roller ring. Clean the cavity floor, especially the circular track where the ring sits.
• Inspect roller ring: Check for flat spots, broken wheels, or warping. Replace the roller ring if damaged.
• Check glass tray: Ensure the tray is not cracked or warped and that it sits flat on the coupler and ring.
• Inspect coupler: Verify the coupler is firmly seated and not bent. Replace if worn.
• Reassemble and test: Reinstall the ring and tray, ensuring the tray's indents align with the coupler. Run the microwave with a cup of water to confirm smooth rotation.
