Richard S Los Lunas , NM April 03, 2015 Appliance: Whirlpool 1.8 Cu Ft Microwave GH5184XPB4 Whirlpool Microwave Gh5184xpb4: Broken door frame. How to replace Complete Door (Black). I had to replace the entire door. The process was quite easy once I figured out that the door only had a removable pin attaching to the top hinge. I thought I was going to have to loosen the entire hinge to get it out. I used screw drivers, socket set and pliers. I only needed the pliers to pull the pin. I wish there would have bee directions with the new door. It would have saved me a lot of time and frustration. The new door fits perfectly. Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
