Replaced fuse. Everything then came back on but after pressing start the microwave would reset. To me it was then acting as if the door was open. I then analyzed how the three door switches functioned and what their purposes were. I used my OHM meter and found that the center switch was shorted closed. I noted that when the door was completely closed, this switch would be in the open position. Since it was shorted closed, I figured that was the issue. I tested my theory by disconnecting the wires to the switch which would simulate and open. At this point the microwave worked simply fine. So, I ordered the switch and replaced, and all is well.
