Do-It-Yourself Story

I wasn't sure if it was the door being warped, the spring return being worn, or the rotary damper failing, so I ordered all to update the door mechanism. I also ordered a new micro switch since one of the switches had started to require more and more pressure to actuate. Figured I'd fix it at the same time. Repair was very straightforward and the videos available on this and other repair sites were very helpful. I found a video that showed replacing the door mechanism on a nearly identical model to my fridge, and it helped with all aspects of the repair. Only minor issue I had on my model was that the water supply line was VERY short and the hole was very tight. I solved this by extending the line with a slightly smaller diameter tubing. I was able to slide the smaller tubing into the old one, and then feed that through the opening. Will make any future repairs much easier. And, the results are fantastic - since I replaced it all, I don't know what part was failing, but now I get that satisfactory 'thump' sealing noise on the ice door, and visual inspection shows no air leakage.
