Product review (5 stars): Great product
This is an OEM part from Whirlpool.  The part number was the same except there was an "A" at the end. It's my understanding the part has been updated. It is a breeze to install. It started making ice within an hour or so. I believe this replacement ice marker makes ice faster than my old one.

Sears wanted $75 more for the part plus shipping and tax.
