Microwave emits a high‑pitched squeal or chirping noise from the turntable area.

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

• Step 1 – Clean components: Remove the glass tray and roller ring. Wash them in warm soapy water, dry thoroughly, and wipe the cavity floor.
• Step 2 – Inspect for damage: Check the roller ring for flat spots or cracks and the coupler for wear.
• Step 3 – Refit correctly: Ensure the roller ring is seated properly and the glass tray engages fully with the coupler.
• Step 4 – Motor replacement (advanced): If noise persists and seems to come from the motor, replace the turntable motor.

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