If your Whirlpool microwave buttons are not working, press each button to see whether some respond while others do not. When only certain buttons fail, the touchpad and control panel are the most likely cause, followed by the touchpad itself. If the microwave buttons are unresponsive across the entire keypad, the user control and display board is the next likely problem, followed by the main control board, control board, or control panel. These parts can affect the microwave start button, number buttons, and other keypad functions, so test the full control panel before ordering a replacement. Enter your model number to find the exact Whirlpool replacement part for your microwave. Replacing the touchpad, control panel, or electronic control board usually requires opening the outer cabinet. Unplug the microwave first, and remember that the high-voltage capacitor stores a lethal charge even after the microwave is unplugged. It must be properly discharged before any interior work. If you are not familiar with capacitor discharge procedures, have a qualified technician perform this repair.

The microwave switch holder is the component that houses the door switches behind the control panel. If the switch holder is damaged or misaligned, one of more switches may not be actuated when the microwave door is closed, which may prevent the buttons on the control panel from functioning. You will need to uninstall the control panel and inspect the switch holder to confirm it is in good condition and secured properly. Replace the switch holder with a new one if necessary.
