Product review (5 stars): Perfect replacement; surprisingly noisy
Perfect fit, easy to replace.  The noise can be a little startling (about a 5 second buzz when the water is replenished after a new rack of ice is made), might just be the location of my refrigerator and the fact that the original part probably wasn't working right for years (the leaking was the last straw).  I may not have needed the replacement icemaker I got to accompany this, but it's nice to have them both as things are working great now.  If you're having an excess water issue, it may well be that the valve is leaking (which this fixes) and not that the water isn't freezing quickly enough.
