How to replace Microwave Outer Door Frame Assembly With Glass. First off, this company rocks. Within 2 hours of me ordering it the new door was being shipped out. I had it only 3 days later. I love a company that knows what it's doing. It's refreshing to me. It was was easy to fix. Just three short screws on one side, then the rest of the door pops off. Also had to take off the handle from broken door and installed on new door. Had to push a little getting new one on, but it went on then I put the three short screws back in. Done. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
