Step 3: Slide and lift the microwave cover out and set aside.
Step 4: Behind the control panel, you will see three door switches (one at the bottom, one in the middle and one at the top).
Step 5: Take out the screws that hold the door switch holder in place.
Step 6: Remove each switch from the holder and note where each one goes.
Step 7: In order to find out if the door switch is faulty or not, press the small button on it. If there is a strong click, the switch is still good, so place it back in the holder. If the button feels loose when you press it, the switch is faulty.
