If your Panasonic microwave buttons are not working, test every key on the control panel. When some buttons respond but others do not, the touchpad and control panel are the most likely cause, followed by the touchpad itself. If the microwave keypad is completely unresponsive and none of the buttons work correctly, the user control and display board may be defective. A faulty main control board can cause the same microwave buttons not working symptom, while a defective control panel is less common but still possible. These parts may also be listed as the membrane switch, user interface board, or display board, depending on your Panasonic model. Enter your model number to find the exact replacement part for your specific microwave. Before replacing any control board or opening the outer cabinet, unplug the microwave and 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.
