How to Troubleshoot & Replace Samsung AP4140182 / DA61-03234A Refrigerator Door Mullion

After a search on the internet for a mullion replacement, I was able to find that I had the exact same problem that someone else had - which was a broken case. Therefore I was able to order a replacement case instead of a new mullion which saved a good amount of money. When I was emailed that the parts were shipped, AppliancePartsPros included a link to reviews by others on what they did to replace their faulty parts. The story submitted by Jonathan R. from Mequon, WI, on March 27, 2016, explained exactly what I needed to do to replace my broken casing. Please refer to his repair summary as it perfectly describes what to do. 

Followed the video for the center hinge replacement and the just exchanged the new case for the old. 

I did like your video. I open the case take out and I cut the wire to replace the case and solder back and put shrink where I solder and put everything back together and work fine 

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. 

I called AppliancePartsPros.com. and spoke to a young lady. After giving her the model and revision number, she recommended the parts I needed for the repair. Once the parts arrived, I looked at the video that they supply which made installation fast and easy. Everything went in without a hitch. Five-star rating for this business which makes small repairs easy for the man who is handy. 

Watched repairs from appliancepartspro.com. Ordered the parts, only had to call once. Followed instructions and fixed the problems.
