LG Microwave buttons not working

If your LG microwave buttons are not working, first check whether some buttons respond while others do not. When only certain keys fail, the touchpad and control panel are the most likely cause, followed by the touchpad itself. If the microwave keypad is completely unresponsive, the user control and display board is more likely defective, followed by the main control board, control board, or control panel. A microwave can still have power and a working display while the microwave buttons do not respond, so test each button carefully before ordering parts. Enter your model number to find the exact replacement touchpad, membrane switch, user interface board, main control board, or control panel for your specific LG microwave. 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 the microwave is unplugged. It must be properly discharged before any interior work begins. If you are not familiar with capacitor discharge procedures, have a qualified technician handle the repair.

07 - LG 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.
