I had changed this icemaker roughly 4 years ago, also with an icemaker purchased here at Appliance Parts Pros. This time, my wife alerted me that there was a big chunk of ice in the ice bin. I looked and saw that it was being caused by water dripping out of my icemaker. I got an inspection mirror, and found that the last half-moon ice section on the icemaker, closest to the door, looked corroded and had no more Teflon (or whatever it is) coating.
I unplugged the fridge, got a quarter inch nut driver, and removed the bottom connector. I loosened the two top screws that it hangs on, unhooked it, and slowly brought it out. I removed the front square white cover from the icemaker, and pushed the connector tab in with a small flat-head screwdriver. That's it. Three screws, simple. Appliance Parts Pros has an excellent video showing the entire simple process.
The only thing I had to do differently, was to take a pair of wire cutters and snip two little tiny protrusions off the stock connector. Even though it comes with additional/different wiring pigtails, my original worked fine except that it wouldn't 'lock in' to the icemaker because those two tiny tabs prevented it from going in far enough to 'click' and lock in.
The fact that I just changed this 4 years ago doesn't bother me; apparently that's all you can expect from an icemaker these days. AppliancePartsPros always has my parts in stock for a good price, and gets them to me in two days using 'Standard' shipping.
One other thing - when I entered my fridge's model number into the "appliance compatibility tool" on the icemaker's page, it says "Sorry, this part is not compatible. See parts for ED5FHEXNQ00"... but it does in fact fit perfectly, and this is my second one.
