If your Samsung microwave buttons are not working, test every key on the control panel before replacing parts. 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 touchpad is unresponsive and none of the buttons work correctly, the user control and display board is the next likely problem. A defective main control board can cause the same symptom, while a faulty control panel is less common. These parts may be listed as the membrane switch, keypad, user interface board, or display board, depending on your Samsung model. Enter your model number to find the exact replacement part for your microwave. Before removing the outer cabinet to access a control board or wiring, unplug the appliance and use extreme caution. The high-voltage capacitor stores a lethal charge even after the microwave is unplugged and must be properly discharged before any interior work. If you are not familiar with capacitor discharge procedures, have a qualified technician perform the repair.
