Product review (5 stars): Useful parts in here
For those who enjoy & are qualified to tinker with their appliances:
One annoying things about modern icemakers is that they seem to break rather more often. Another annoying thing is that the particular replacement kit which actually matches my fridge costs more than twice as much as this kit, and that it is very hard to find the parts to fix an icemaker sold individually instead of a pull replacement.
The things most likely to break on the part of your icemaker in the freezer compartment are in the control section (the boxy part on the left side of the picture which contains motor, gearing, temperature sensor and some other bits), and that the ice tray has a thin coating that if scrapped up will make the system work harder (and possibly help the motor fail). The things least likely to break in your icemaker are the pieces that are different between this kit and the more expensive ones- the mounting bracket for attaching, the cable from the control section to the plug, the plastic catch bucket to route the water into the mold, and the arm for the on/off switch.
I picked up this kit, removed the pieces that were different and replaced them with the ones from my old icemaker. For half the price, and some careful fiddling (again, only do this if you enjoy this sort of thing, as it may take longer than the price difference is worth) I once again had a working ice maker.
Main things I had to move were the power/control cord, the on/off arm, the catch bucket, and the mounting bracket. The place to pay special attention is the wiring- take pictures as you go and make sure everything gets reconnected. Missing a ground could really ruin your day.
Note one could in theory also get this kit, just take the broken bit out of it and install in your old icemaker. I chose my approach so that as many of the wear pieces were replaced as possible while I was at it- and I still have those pieces of the old icemaker that hadn't failed as backups.
