When a Sanyo 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. Next, inspect the glass tray drive coupling and glass tray support for cracks, stripped teeth, or other damage, then replace any worn part. Confirm the turntable option is turned on if your Sanyo model has that setting. If the motor does not receive incoming power, the user control and display board or main control board may be defective, although the motor is more commonly at fault. A damaged turntable motor, coupler, support, or control board can cause a microwave turntable not turning, microwave not spinning, microwave plate not turning, or microwave carousel not spinning. Enter your model number to find the exact replacement part for your specific Sanyo microwave. Testing or replacing a control board may require opening the outer cabinet. The high-voltage capacitor stores a lethal charge even after the microwave is unplugged, so it must be properly discharged before any interior work. If you are not familiar with capacitor discharge procedures, have a qualified technician handle the repair.

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).
