The microwave turntable does not rotate during cooking, but heating still works.

Safety: Unplug the microwave before accessing the bottom panel or internal components.

• Check Glass Tray and Support: Remove the glass tray and roller ring. Clean any food debris and ensure the roller ring turns freely.
• Inspect Coupler: Check the plastic coupler that fits onto the motor shaft for cracks or rounding.
• Access Motor: On many KitchenAid models, the turntable motor is accessible from the bottom. Remove the bottom cover and disconnect the motor.
• Replace Motor or Coupler: If the motor shaft does not turn when powered (testing should be done by a professional) or is seized, replace the turntable motor. Replace a damaged coupler or roller ring as needed.
