If your Panasonic 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. Next, inspect the glass tray drive coupling and glass tray support for cracks, stripped teeth, or other damage, and replace either part if needed. A microwave plate not turning can also result from the turntable option being switched off, if your model has that setting, so confirm it is enabled. If the motor tests good, check whether it is receiving power while the microwave operates. No power at the motor can indicate a defective Panasonic user control and display board or main control board, although either board is less likely than the motor. Enter your model number to find the exact replacement turntable motor, coupling, support, or control board for your specific microwave. Repairs that require removing the outer cabinet must be handled carefully because the high-voltage capacitor can store a lethal charge even after the microwave is unplugged. The capacitor must be properly discharged before interior work, and this repair may require a qualified technician if you are not familiar with safe capacitor discharge procedures.

04 - Panasonic 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).
