Microwave light turns on and timer counts down, but turntable does not rotate.

Safety: Unplug the microwave before accessing the underside or interior components.

Simple checks:

• Remove the glass tray and roller ring. Inspect for broken wheels or obstructions.
• Check the plastic coupler that fits over the motor shaft for cracks or wear.

Motor access:

• On many Magic Chef models, the turntable motor is accessed from the bottom. Remove the bottom cover (if present) after unplugging the unit.
• Disconnect the motor wires and test the motor for continuity with a multimeter. An open reading indicates a failed motor.

Corrective actions:

• Replace a failed turntable motor with the correct Magic Chef turntable motor.
• Replace a cracked coupler or damaged roller ring.
• Ensure the motor mounting screws are tight and the shaft turns freely.
