Product review (4 stars): Some minor modifications needed but works great
We got 17 years out of our KitchenAid side-by-side's icemaker, which I can't really complain about since many people have to replace theirs much sooner. I believe feeding filtered water to icemakers does help their longevity, and we do this.

I had to make three minor modifications to get this to work, but they were easy. Check out YouTube videos for "replace whirlpool icemaker." The videos show the first of the three modifications. Replacement icemakers no longer come with the metal piece that turns the icemaker on or off as the level of ice rises. It's easy to swap out the same piece on the old icemaker to the new one once you know to start with the piece in the down position.

Replacement icemakers also don't come with the bracket piece and the screw that support the bottom of the icemaker and attach it to the freezer wall. Again, it's fairly easy to remove this bracket from the old icemaker and reuse it on the new one.

The third modification was that I had to cut part of the replacement icemaker with a hacksaw to allow the water fill tube to sit in the right position. My old icemaker, and the replacement ones shown in the videos, have a hole in the plastic on the back side of the icemaker for the water fill tube to fit through. The hole holds the tube in place. My replacement icemaker didn't have this hole, and the lack of it would cause the fill tube to sit too high and water to spill in the freezer. If you see a difference in the new and old icemakers you have in this area, just take a hacksaw and cut a triangle shaped slot to fit the fill tube in, and it will sit in the right position and work great.

This is an easy project for a do-it-yourselfer and will save some good money over having a repairman do it.
