Tappan Microwave turntable not turning
If your Tappan microwave turntable is not turning, the turntable motor is the most likely cause. A failed motor can make the microwave plate not turning, even though the microwave heats normally. Unplug the microwave and use a multimeter to test the motor for continuity. Replace the motor if it does not have continuity. Next, inspect the glass tray drive coupling for cracks, stripped teeth, or other damage, then check the glass tray support for the same problems. If the motor has continuity, test whether it is receiving power. If it is not, the Tappan user control and display board or main control board may be defective. Also confirm that the turntable option is enabled, if your model includes that setting. Enter your microwave model number to find the exact replacement turntable motor, coupling, tray support, or control board for your specific appliance. If repairing the microwave requires removing the outer cabinet, use extreme caution. The high-voltage capacitor can store a lethal charge even after the microwave is unplugged and must be properly discharged before interior work. If you are not familiar with capacitor discharge procedures, have a qualified technician perform the repair.
