Product review (5 stars): An easy fix - you can do it!
If you, like me, are worried about whether it will work with your model or not, just eyeball it. I suspect that if your existing ice maker unit looks very similar to this, you're probably OK. Kenmore, Whirlpool, and who knows how many other brands all use the same core mechanism. Which makes sense - there's no point in reinventing the wheel for every fridge, and it makes it cheaper/easier for them to service.

I have a 14-year-old (or so) Whirlpool model ED5THAXMS00 - its ice bin is in the door, not a drawer inside the freezer. So my machine's ice tray is parallel with the face of the door, it does not go front-to-back like many others. I don't know what went wrong with it; I think the ice ejector motor just locked up or burned out.

So as you look at the photo of this, see how the white plastic lower edge, along the front, is at a 45-degree angle? Well, instead of a sloped front, like this, mine is flat. I realized that this model would not fit, as-is and I was about to box it back up. But, upon closer inspection, I realized I could swap out the front white plastic plate from my old one into the new assembly easily. It's the exact same basic mechanism, with the exact same dimensions. So I had to dismantle the motor housing (the black plastic part in the photo - it's 3 screws), and removed the sloped plate, and swapped in the flat front plate from the old one. Perfect fit. Took 5 extra minutes, if that.

Also, my fridge has a light sensor across the door frame that tells the machine when to make ice or not. If the bin is full, the light sensor is blocked, and it won't make more ice. This ice unit comes with a wire lever that "feels" if the bin is full or not. This is for the internal drawer type of ice maker. If you have the door bin with the light sensor, you can just remove that wire lever, it comes right off.

Seeing as my fridge was so old, my wife was looking at new refrigerators. And after doing this repair, I gotta say there's nothing more satisfying than a DIY repair in which you spend $40 instead of $1000 or more! Heck, a service call from an appliance shop probably would have run $300 surely. Very happy with this purchase, it was a surprisingly easy fix, even for an appliance novice like myself.
