Product review (4 stars): Great Price and fixed my Icemaker overflow issue
This was the part that fixed my GE Icemaker from over flowing.  I couldn't figure out how the "fill cup", basically a funnel for the water tube to guide the water into the ice maker itself, was freezing solid with ice.  It's has a hole in the bottom and water is only in the cup for a couple seconds!  After my entire icemaker and back of freezer becoming encased in ice (more than once), I figured out the issue.  The old valve wasn't shutting off the water all the way so there was very slow drip of water. Basically drop by drop it would go into the fill cup and freeze to it,therefore building up layers of ice over several hours, until it was full and additional drops began overflowing. The part is very easy to install from the back of the refrigerator.  NOTE: There are two tubes that push into the valve (one for the ice maker, one for the water dispenser) can become brittle over time.  The white tube for the water dispenser was brittle and broke as I tried to insert it.  Therefore I had to by another part called the Water Storage Coil - GE part WR17X11324.  It was also pretty easy to install once you know how.  It mounts in the lower refrigerator cabin and there are two holes to pass the tubes through.  Short side goes down to this valve.  Long section routes around to the front and connects at the lower left, below the freezer door hinge. (FYI I have a side by side model). Check repairclinc.com for some great install videos.  The only reason I didn't give this 5 STARS is that is it seems the Icecubes are slightly smaller, meaning the valve shut off timing is different and turns off quicker.  We will see if that affects the "dispense through the door" function where the auger pushes the ice forward.
