If your Toshiba microwave buttons are not working, press each button to identify the pattern. If some buttons respond while others do not, the touchpad and control panel are the most likely causes, followed by the touchpad itself. If the microwave keypad is completely unresponsive, the user control and display board is the next likely culprit, followed by the main control board, control board, or control panel. This applies whether the microwave start button is not working, the number buttons are unresponsive, or the entire microwave touchpad is not working. Before replacing a part, check for stuck or damaged keys and confirm that the control panel is clean and dry. Enter your model number to find the exact replacement part for your specific Toshiba microwave. Any repair that requires removing the outer cabinet must be handled carefully. The high-voltage capacitor can store a lethal charge even after the microwave is unplugged and must be properly discharged before interior work begins. If you are not familiar with capacitor discharge procedures, have a qualified technician perform the repair.
