To get to the fuse, you need to remove the vent and the touch screen panel. The vent is held to the microwave by two screws. Remove the screws and then the vent. Once the vent is removed, you should see a screw on top of the touch screen panel. Remove the screw then push the touch screen panel from the bottom. Now grap the top of the panel and pull towards you. You should be able to see a white fuse in the space behind the touch screen panel. I hope this will help.
