Dacor DMW2420S 24 in 1.2 cu ft 1000W Sensor Microwave Oven MECH-TURNTABLE Error Fix: Turntable Motor Failure

The turntable does not rotate during cooking, leading to uneven heating. The turntable motor, drive coupling, or support roller is faulty. Check the turntable roller ring and guide for obstructions or damage. Remove the glass tray and inspect the drive coupler for wear. Listen for a humming sound from the motor — if the motor hums but the turntable doesn't turn, the drive coupling is stripped. If there is no motor sound, the turntable motor has failed and must be replaced.
