If your Emerson 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 it has no continuity, replace the turntable motor. A broken or stripped glass tray drive coupling is another highly likely cause, so gently pull the coupling from the motor shaft and inspect it for damage. The glass tray support, also called the turntable roller guide or support ring, may be broken or stripped and should be checked next. If the motor does not receive incoming power, the Emerson user control and display board or main control board may be defective, although the motor is much more likely to fail. Also confirm that the turntable option is turned on if your model has that setting. These issues can cause a microwave turntable not turning, microwave not spinning, or microwave plate not turning. Enter your model number to find the exact replacement part for your Emerson microwave. If testing requires removing the outer cabinet, remember that the high-voltage capacitor can store a lethal charge even after unplugging. It must be properly discharged before interior work, so use a qualified technician if you are unfamiliar with capacitor discharge procedures.

If the microwave turntable is not turning the glass tray drive coupling could be broken or stripped out. Gently pull the coupling off the drive motor shaft to inspect the drive coupling for damage.
If the microwave turntable is not turning the glass tray support could be broken or stripped out. Gently pull the support off the drive motor shaft to inspect the tray support for damage.
04 - Emerson 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).
