Product review (5 stars): Problem solved
This valve perfectly matches the original in our 632 side by side subzero.  We had two problems. First,the quantity of ice slowly decreased over time- theory was the water inlet was not opening properly. Second, fist sized clumps of ice we're forming in the bin- theory was the inlet wasn't closing all the way. I replaced the water filter first and then the water inlet valve. The ice quantity is back to normal and ice clumping is minimal. Installation is a back twister but not difficult.
