My door handle finally broke completely off. The door itself was cracked in a few places so I decided to replace the whole door. The work itself it actually really easy. The door attaches to the microwave with two hinges. On the door itself look at the top hinge. Next to it is a black tab. This tab moves horizontally. You can use a flathead screwdriver to push this tab. To remove the old door, you want to push this towards you (towards the door handle is another way to think about this) while simultaneously pushing the door upwards. If you don't push on the tab while pushing up on the door, the door doesn't move. But pushing on the tab will allow the door to go upwards and off the hinge. Then door will detach from the microwave. Once the door is off, you'll understand how to put in the new replacement door. It's very easy. I was able to do this myself, but a second pair of hands might make this easier as one person pushes on the tab while the other person pushes up on the door. 3 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
