Customer Questions and Answers for Microwave Door Switch Kit by Whirlpool

Hello Brian. The is no way of testing the control panel for the door switches. The best way to test the switches is testing the switches themselves. NC and COM should read closed and NO and Com should read open. This should change when the button on the switch is pressed. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html
