When your Montgomery Wards 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 and glass tray support, also called the turntable coupler and roller guide, for broken or stripped sections. Gently remove these parts from the motor shaft and check for damage. If the motor does not receive incoming power, the user control and display board or main control board may be defective, although a failed turntable motor is more common. Also confirm that the turntable option is turned on, if your microwave has that setting. A microwave plate not turning can create hot spots because food is not rotated through the microwave energy. Enter your model number to find the exact replacement turntable motor, coupling, support, or control board for your specific Montgomery Wards microwave. Any repair that requires opening the outer cabinet must be handled carefully because 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 capacitor discharge procedures.

04 - Montgomery Wards Microwave User Control and Display Board
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).
