Product review (5 stars): Fixed my ice maker
My ice maker stopped making ice, and based on forums and other web sites, I determined the problem was the sensor boards, which made the fridge think that the bin was always full.  I checked out many sites, and found the genuine parts to be pretty expensive, so I figured I would try this low cost one first.  I only had to replace the smaller sending unit, which took about 5 minutes, and now my ice maker is working perfectly again.
