Microwave buttons not working

When your microwave buttons are not working, start by testing every key on the control panel. When some buttons respond but others do not, the microwave touchpad and control panel are the most likely causes, followed by the touchpad itself. If the microwave buttons are unresponsive across the entire keypad, the user control and display board is a likely failure point. The main control board may also be defective, and the control panel is a less common possibility. These parts can cause a microwave start button not working, microwave number buttons not working, or a microwave touchpad not working even when the display has power. Enter your model number to find the exact replacement part for your specific microwave, since touchpads, control panels, and boards are not interchangeable across every model. Before replacing any part that requires opening the outer cabinet, unplug the microwave and use proper safety procedures. 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.

07 - Microwave Switch Holder

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.
