Microwave produces a high-pitched squeal or chirping noise from the turntable area.

Safety first: Stop the microwave and allow components to cool before handling.

• Step 1 – Remove and clean: Take out the glass tray and roller ring. Wash them with warm soapy water and dry thoroughly.
• Step 2 – Clean cavity floor: Wipe the turntable support area to remove crumbs and residue.
• Step 3 – Inspect roller ring: Check for flat spots, cracks, or missing rollers. Replace the roller ring if damaged.
• Step 4 – Check coupler: Ensure the plastic coupler is seated properly and not cracked.
• Step 5 – Reassemble and test: Reinstall components and run a short cycle with a light load to confirm quiet operation.

Note: Do not lubricate the roller ring; it should run dry and clean.
