Microwave emits a loud high-pitched squeal or scraping noise from the turntable area.

Safety first: Unplug the microwave before cleaning the turntable mechanism.

• 1. Remove and clean: Take out the glass tray and roller ring. Wash both in warm soapy water and dry.
• 2. Clean cavity floor: Wipe the floor where the roller ring sits to remove crumbs or hardened spills.
• 3. Inspect roller ring: Check for flat spots or broken wheels. Replace if worn.
• 4. Inspect tray: Ensure the glass tray is not warped or chipped around the center hub.
