Product review (5 stars): Cheaper than buying a "replacement" part
My 13-year old Kenmore 106.xx side-by-side was having problems with the ice maker overflowing into the ice bin (a common problem according to the web). After fiddling with the adjustment screw and cleaning all the contacts with no improvement, it was time to order a new unit. I confirmed on the Whirlpool site that the #ECKMF94 was the replacement for my model. The unit arrived and was exactly the same as the original, with the exception of the size and shape of the on/off arm. Installation took me less than five minutes. There was one 1/4" hexhead screw to remove that locks the unit in place. Two other screws are loosened so that the unit can be lifted up and out. Then you simply unplug the wiring harness. I swapped out the on/off arm with the original (simply pulled out at each end), reinstalled the old, deeper arm, and within a few hours, I had ice again.

Exact "replacement" units for this model from the retailer were well over a hundred dollars, yet this model came with an extra ice bin and a new supply valve that I'm saving for future use. This is a really simple replacement job that I think anyone can do. If this one lasts as long as the first unit, it should outlast the refrigerator.
