If your Maytag microwave turntable is not turning, the turntable motor is the most likely cause. Unplug the microwave and use a multimeter to test the motor for continuity. If the motor lacks continuity, replace it. A broken or stripped glass tray drive coupling is the next likely problem. Gently remove the coupling from the motor shaft and inspect it for damaged teeth or cracks. The glass tray support, also called the turntable roller guide or ring, can also be broken or stripped and should be checked. If the motor is not receiving power, the Maytag user control and display board or main control board may be defective, although either board is less likely than the motor. Also confirm that the turntable option is enabled, if your model has that setting. A turntable that is not turning can leave hot spots and cause uneven cooking. Enter your Maytag microwave model number to find the exact replacement turntable motor, coupling, support, or control board for your appliance. Most turntable repairs do not require removing the outer cabinet. If cabinet removal is necessary, remember that the high-voltage capacitor can store a lethal charge even after the microwave is unplugged. It must be properly discharged before interior work, so use a qualified technician if you are not familiar with that procedure.

The user control and display board might be defective. However, the turntable motor is much more likely to be at fault. First, test the incoming power to the turntable motor. If the motor is not getting power, the user control and display board may be defective. If the user control and display board is defective, replace it.
When the microwave turntable turns, the food is cooked evenly. If the turntable stops turning there may be hot spots where the microwaves are concentrated in one area. If the turntable is not turning, confirm the turntable option is turned on (if applicable).
