I ordered a new microswitch and the bracket that holds it. The bracket depends on plastic retainers about the diameter and dependability of a toothpick. Those had broken off so the switch body moved instead of just the button on the switch when the dispenser arm was pushed by a user. The video from APP was super helpful, although the gloves the tech wore hid some things I needed to see, but not too badly. Also, my 23-year old refrigerator had some different wiring than shown in the video, but no show stoppers. It took me about ten minutes to complete the replacement and worked perfectly when reconnected. I'm not particularly handy, so I'm very grateful for the well-made video.
