I followed someone else's repair steps on the parts page. They were well written. The repair must be done carefully or there is a possibility of breaking or bending the parts. Work the plastic tabs off of the metal inner case carefully. The new case will show you where the tabs are located. I used a utility knife blade, a slim flat bar as well as a straight screwdriver slipped between the parts. It seemed like working the ends and all the way down one side worked best to separate them. I forgot to put the center hinge stop and screw in before I reassembled the case so I had to take the case apart again to get that done. The insulation inside the case needs to be handled very carefully as well. Also I did not understand that the electrical connections were hiding in the frig body. I kept looking for them in the case thinking they were hidden in the foil insulation. But they were just inside the body of the frig and when I pulled them out they were fairly easy to unlock and take apart and put back together. It is easy to lose track of which is top and bottom, right and left of the parts and how the electrical wire is routed into the case. I recommend taking pictures with phone before each dis-assembly step to aid in getting it back together correctly. I had gotten used to guiding the broken door mullion closed. It is so nice to have the door working properly again! Took about an hour for me.
