Product review (4 stars): Great Replacement
I used this to replace my 626636 unit in my Kenmore fridge.  Working Great!
Hooked right up perfectly and started making ice about 45 min later after it cooled down.  As others said, it's not the fastest at making ice but neither was the original.
Be sure to keep the power cord from your previous unit and the 3 screws that attached it to the side of the freezer.

Super stoked I gave this a try!
