Product review (1 stars): UPDATE: Buyer Beware!
My icemaker was not working, and I found a troubleshooting video on YouTube which helped me narrow down the problem to my inlet valve.  I bought this replacement, and installed it in about five minutes and the icemaker works now.

Update.  BUYER BEWARE! Today the water dispenser valve failed to the open position, causing water to spray out of control onto my kitchen's hardwood floor.  Had I not been home, I would have been facing several thousands of dollars of water damage.  These valves should fail to the closed position and only open when energized.  They should never fail to the open position, especially when it is only 11 months old.  I will look for another replacement from another supplier.
