DM84KWB Magic Chef Microwave - Overview

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

I mistakenly thought I had to remove the microwave to get to the back, not so. I would have had access to what I needed to unscrew; but I have to admit the hassle of taking it down and putting it back equals having to work on it attached to the shelf-your call on how you do this. I unscrewed the front top to remove the vent piece that is across the top front of the microwave. This will reveal the control panel screw. (While you have the vent removed you might want to clean the vent and the exposed filter.) carefully lift and pull out control panel. I unplugged a piece as the wires were tied tight. It will not completely detach, so carefully tip it back from exposed insides. The fuse is not clear but white with silver ends so look in upper right for it. I popped it out and replaced it. Replugged the wired part to cover and carefully fit tabs in and slide down to secre. Replace screw, replace vent piece and secure screws on top of microwave. I plugged it in to test before putting it back above my stove.
