If your Frigidaire microwave buttons are not working, press every key on the control panel to identify the pattern. If some buttons respond while others do not, the touchpad and control panel are the most likely cause and should be replaced. A defective touchpad alone is the next most likely cause, especially when the microwave keypad is not working but the display and other functions operate normally. If the microwave buttons are unresponsive across the entire panel, the user control and display board may be defective. The main control board is another possible cause, followed by the control board and, less commonly, the control panel itself. These failures can cause the microwave start button, number buttons, or other keypad functions to stop responding. Enter your Frigidaire microwave model number to find the exact replacement part for your appliance. Some control repairs require removing the outer cabinet. Unplug the microwave first, and remember that the high-voltage capacitor can store a lethal charge even after power is disconnected. It must be properly discharged before any interior work, so use a qualified technician if you are not familiar with capacitor discharge procedures.

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.
