I had the original sensors in my Frigidaire, which were now about 18 years old. The water dispenser would work, but I would have to push in the lever and then draw it back until it found that "sweet spot." I finally got annoyed enough with the problem that I looked online. I almost purchased the dispenser actuator (the paddle), and glad I didn't because it was not the problem. Unless your lights are out, or it broke, the culprit will be these little dispenser switches which get pressed every time you get ice or water. I purchased two AP6887337 dispenser switches, and figured I would swap out both while I had it apart. I watched a few of the videos and read some of the comments before the install, and it made things WAY easier. I would echo another poster's comments about the water tube being the most difficult portion of the process. I pushed mine back up through the frame with a pen when removing. We have hard water where I live, so I also used that opportunity to scrape off the scale which had accumulated in the opening where the tube comes through and other impacted areas. Screws holding some of these internal components together are tiny, so make sure you have a two phillips screwdrivers to accommodate large and small screws. The tube did not want to go back into the hole upon reassembly the first time, even when using some needle nose pliers to try and get it back into the hole. I fixed that problem by putting a few drops of cooking oil on the water line and inside the hole, and it went right in. I can't say enough good things about the APP folks. I have purchased parts for my refrigerator, stove, dishwasher, washing machine and dryer from them, and they are my go-to. The videos they make are second to none, especially when talking about how to remove panels so as to not break the plastic tabs underneath. Hours of time saved, and no extra parts get broken. Appliances are crazy expensive, and given this refrigerator was built better than the stuff on the market now, I want to do what I can to keep it going. A $22 fix beats buying a new $1500 refrigerator. Thanks APP!
