Product review (4 stars): Our icemaker started to overfill the tray at random times ...
Our icemaker started to overfill the tray at random times, and then stopped filling altogether. Ordered this valve to solve the problem, which it did. I only needed to pick up one additional part which was the adapter to connect my 1/4" water supply line to the new valve. My supply line has a 1/4" female fitting which threaded directly onto the original valve in the refridgerator. After purchasing and adding the new fitting to my supply line, I now had a quick connect fitting at the end of my line, which allowed the supplied tubing to be fed from the water supply. The install took about 10 minutes. My Kenmore has threaded connectors on the original valve; I just slid the nuts a few inches up the line and then made a clean straight cut just above the flare on the plastic tubing. Only lost 1/2 inch of tubing making the new clean square cut. This allowed the two water lines to slip into the valves quick connect fittings smoothly and I would be sure they were in far enough to know that there would be no leaks. Turned on the water supply line while the refrigerator was still away from the wall, just to be sure that I could inspect that everything was dry and that there were no leaks.  There are multiple videos online which cover this install - check them out.  Our icemaker has been filling to the correct level since adding the new valve, and has been cranking away making cubes over the last 12 hours.
