First I removed upper front grill by removing two Philips head screws on top and pulling off. This exposed the Philips head screw which holds control panel in place. After removing screw I pushed up on panel and it came off to expose fuse. With needle nose pliers I removed old fuse and again with pliers held new fuse in position. With the help of a bladed screwdriver, I pushed new fuse into holder, then replaced panel, screw and grill. This took less than 15 minutes even as one of the wires on control panel pulled out of connection and took some time to locate where to reconnect, otherwise was an easy fix .
First i removed the 3 phillips head screws from the back of the microwave,these hold the wrap around cover in place, then slid the wrap around cover off towards the back side of microwave, next from inside the microwave i removed 1 screw holding the front operating panel, this screw is located staight up from the push button towards the top of the microwave, I pulled the panel out enough to get the broken push button out, then i installed the new push button,then reinstalled the operating panel then the wrap around cover, very simple repair saved a lot of money by replacing the part rather than buying a new microwave.
