Microwave runs but produces a rattling or scraping noise from the turntable area.

Safety first: Unplug the microwave before handling the glass tray.

Steps:

• Remove tray and ring: Take out the glass tray and roller ring. Clean the cavity floor and roller track.
• Inspect components: Look for flat spots or broken wheels on the roller ring and chips or cracks on the glass tray.
• Reinstall correctly: Place the roller ring properly in its track and seat the glass tray on the coupler.
• Balance the load: Avoid placing heavy items off-center on the tray.

If noise persists:

• Replace the roller ring or glass tray if damaged.
