Carlton D Columbia , MD June 20, 2020 Appliance: Maytag Microwave MMV6180WB2 Maytag Microwave Mmv6180wb2: Microwave door handle and a portion of the door frame cracked after years of daily use. How to replace Microwave Door. Opened the door and removed the set screw on the top left end of the door using a hex wrench. The door was easy to remove from the hinge after the set screw was removed. With the door removed I cleaned around the hinges and removed the years of grease build up. I put a few drops of 3:1 oil in the hinge holes to lubricate them. Finally I installed the new door. Done! Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
