Hello, and thank you for using this service. I'll be helping you with your problem today.

So unfortunately this means that one of your door switches has failed. There are 3 door switches and usually the bottom one is the one that fails, but you'd need to remove the outer shell of the microwave and test the switches to know for certain which switch is bad. Below is a link to a video that shows you how to test the actual door switches inside your microwave to know which one to replace. Now access on your microwave is completely different however. You will need to remove 1 screw coming in from the right and left side toward the bottom. Then remove the screws coming in from the back of the microwave along the top, right and left edges. Once all the screws are removed, the entire outer shell will pull straight back, up, and off so that you can test the switched through the right side of the microwave.
