LG Microwave turntable not turning
An LG microwave turntable not turning is usually caused by 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 for cracks or stripped teeth, then check the glass tray support, also called the roller guide or turntable ring, for damage. Make sure the coupling and support are seated correctly on the motor shaft and that the glass plate can rotate freely. If the motor is not receiving power, the LG user control and display board may be defective, although the motor is much more likely to fail. Also confirm that the turntable option is enabled if your model allows it. If the motor still does not receive power, the main control board may be at fault. Enter your model number to find the exact replacement turntable motor, coupling, support, user control and display board, or control board for your LG microwave. Any repair requiring removal of the outer cabinet must be handled carefully because the high-voltage capacitor can store a lethal charge even after the microwave is unplugged. Proper capacitor discharge is required, and a qualified technician should perform the work if you are unfamiliar with the procedure.

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.

07 - LG 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.
