Product review (5 stars): Fixed my icemaker!
This is the OEM replacement product, but Whirlpool did change the design of the valve slightly since our refrigerator was new in 2001.  No worry, though.  Even though it is slightly different, it fit and worked perfectly.  It came with a few extra parts I didn't need - they are included "just in case" a different application needed them.  There is a youtube video on how to do this on a Whirlpool refrigerator that shows you just what to do if your old valve is configured slightly differently.  I got my ice maker working again and the price was right and the installation was simple for anybody that can use a screwdriver and a razor knife (to cut the plastic tubing).
