How to Fix / Troubleshooting

Safety first: Unplug the microwave before accessing the underside.

Steps:

  • 1. Remove and inspect tray: Take out the glass tray and roller ring. Clean both and the cavity floor.
  • 2. Check coupler: Inspect the turntable coupler for cracks or rounding of the drive splines. Replace if damaged.
  • 3. Test motor: With the tray removed, start a short cook cycle and observe the coupler. If it does not turn, the motor or its circuit is faulty.
  • 4. Replace motor (experienced DIYers): Access the turntable motor from the bottom, disconnect wiring, remove mounting screws, and install a new motor of the same specification.
