Toshiba Microwave turntable not turning
If your Toshiba microwave turntable is not turning, the turntable motor is the most likely cause. Unplug the microwave, access the motor, and use a multimeter to test it for continuity. If the motor has no continuity, replace it. A broken or stripped glass tray drive coupling, also called a turntable coupler, is another highly likely cause, so gently remove it from the motor shaft and check for damaged teeth. Next, inspect the glass tray support, turntable roller guide, or turntable ring for cracks or stripped areas that prevent the plate from rotating. If the motor does not receive power, the Toshiba user control and display board or main control board may be defective, although these parts are less likely than the motor. Also confirm that the turntable option is turned on if your model has that setting. Enter your microwave's model number to find the exact replacement turntable motor, coupling, support, or control board for your Toshiba microwave. If accessing any part requires removing the outer cabinet, remember that the high-voltage capacitor can store a lethal charge even after unplugging. Proper capacitor discharge is required before interior work, and a qualified technician should handle it if you are not familiar with the procedure.

04 - Toshiba 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 - Toshiba 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.
