Microwave turntable does not rotate, but heating still occurs and timer counts down.

Safety: Unplug before accessing underside or internal parts.

Steps:

• 1. Check tray seating: Ensure the glass tray is properly seated on the center coupler and support ring.
• 2. Inspect support ring: Remove the tray and ring. Clean wheels and track. Replace the ring if wheels are missing or seized.
• 3. Check coupler: Inspect the plastic coupler for cracks or rounding. Replace if damaged.
• 4. Test motor: Run a short cycle with tray removed and observe if the coupler turns. If not, test and replace the turntable motor as needed.
