The model number will most likely appear on either a paper sticker or a metal plate. Your appliance's model number tag may look similar to the sample model number tags shown here (model number highlighted in yellow):

So, I called and spoke with a very knowledgeable technician and she explained why plus helped me order the part over the phone. When I received the part, the switches were already mounted in the frame and the frame was modified compared to the OEM frame. As I began to remove the old frame, I discovered why the new frame was modified. It was as if PartSelect had done many of these door interlock repairs and they knew exactly where and how to modify the frame and communicated this with the manufacturer, because the new frame installation was very easy, there was nothing hard about installing the new frame with the switches already in place. I then reconnected the wiring to the switches and tested the microwave and it works fine now, Problem solved, Thanks PartSelect.com
Make sure 110v at the transformer. Activate switch controlled by the push button to open and close door. Push in the small metal arm on the switch with none metallic probe. If power is restored to microwave the switch is faulty and need replacement. One switch is not available, the whole 3 switch assemble has to be purchased.
