When a Magic Chef microwave buttons are not working, start by checking whether only some buttons fail or the entire keypad is unresponsive. When some buttons respond correctly while others do not, the most likely cause is a defective touchpad and control panel, followed by a faulty touchpad. If none of the buttons respond correctly, the user control and display board is the next likely problem, followed by the main control board, control board, or control panel. These failures can cause a microwave start button not working, microwave number buttons not working, or all microwave buttons unresponsive. Press each button firmly and compare its response before ordering parts. Enter your model number to find the exact replacement touchpad, membrane switch, control panel, user interface board, or control board for your specific Magic Chef microwave. Replacing a touchpad may be straightforward, but accessing a control board requires opening the outer cabinet. The high-voltage capacitor stores a lethal charge even after the microwave is unplugged, so it must be properly discharged before any interior work. If you are not familiar with capacitor discharge procedures, have a qualified technician complete the 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.
