If your Modern Maid 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 has no continuity, replace it. Next, inspect the glass tray drive coupling for damage, cracks, or stripped teeth, then check the glass tray support, which can also break or strip where it engages the motor shaft. If both parts look good, confirm the turntable option is turned on, if your model has that setting. A defective user control and display board can prevent power from reaching the motor, but the motor is much more likely to fail. Test for incoming power at the motor before replacing the user control and display board. If the motor is not receiving power, the main control board may be faulty. Enter your Modern Maid microwave model number to find the exact replacement turntable motor, glass tray drive coupling, glass tray support, user control and display board, or main control board for your appliance. Any repair that requires removing the outer cabinet must be handled carefully because the high-voltage capacitor can store a lethal charge even after unplugging. Properly discharge it first, or hire a qualified technician if you are not familiar with that procedure.

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).
