Microwave turntable not turning
When your microwave turntable is not turning, the most likely cause is a failed turntable motor. Unplug the microwave and use a multimeter to test the motor for continuity. If it has no continuity, replace the motor. Next, inspect the glass tray drive coupling and glass tray support for damage, cracks, or stripped teeth. Gently remove each part from the motor shaft and replace it if needed. If the motor is not receiving power, the user control and display board or main control board may be defective, although these are less likely than the motor. Also confirm that the turntable option is turned on, if your microwave has that setting. A working turntable helps cook food evenly by preventing concentrated hot spots. Before replacing parts, enter your model number to find the exact replacement part for your specific microwave. Do not open the outer cabinet unless you know proper microwave safety procedures. The high-voltage capacitor can store a lethal charge even after the microwave is unplugged and must be properly discharged before any interior work. If testing wiring, the control board, or other internal components requires cabinet removal and you are not familiar with capacitor discharge procedures, use a qualified technician.

04 - 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.
Common
05 - Turntable option turned off
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).
Common
06 - Microwave Control Board
The control might be defective. However, the turntable motor is much more likely to be at fault. First, check the incoming power to the turntable motor. If the turntable motor is not getting power, the main control board may be at fault.
Common
07 - Microwave Touchpad and Control Panel
The touchpad and control panel might be defective. However, the turntable motor is much more likely to be at fault. First, test the turntable motor. If the motor is not defective, it is possible that the touchpad and control panel are defective. To determine if the touchpad and control panel are defective, try pressing each of the buttons on the control panel. If some of the buttons respond correctly while others don’t, replace the touchpad and control panel.
