To verify if you have a bad valve in the first place read on... I first pulled out the ice maker to remove all the frozen water including the inlet section which was a huge solid waterfall of ice. While it was out completely disconnected I cleaned/chipped out the freezer section ice puddle. I also completely melted the ice cubes and ice puddles off the ice maker at the fill bucket end in the sink with running water careful to not get water near the power cord area. I then put a tall plastic cup where the ice maker fill tube was coming out in the freezer to test for water leakage. Nothing came out after an hour so I tested running water from the refrigerator water dispenser. One cup was not enough to notice a build-up of water coming from the ice maker fill line. So I filled up two tall glasses like we often do when filling out large mugs. That exposed water coming out of the ice-fill line a couple table spoons worth. It was then obvious to me the problem was that the duel solenoid water valve was slightly opening on the ice fill line when using the water dispenser. At that point, it was clear that the duel water valve solenoid needed to be changed. This water valve part fixed the problem perfectly like new once installed. It did not have directions, but the online video gave me a clue on what to expect even though it was not the same exact valve set-up. If you are a typical DYI person it was not too bad. If you are not, then call a repair person and pay the bucks. If you do the above testing to prove it is just a valve control issue don't let a refrigerator repair person sell you a replacement ice maker too !! If you do the job yourself I highly recommend marking both power connectors and all three water lines to where they connected to the old valve for reference. Taking several pictures before disassembly is ALWAYS a wise move !!! I'm a very good DIY person and l did have to refer to a few of my pictures to recall reassembly locations. Note: the big white plastic cover had to be snapped off to allow the clearance to mount the new valve in place. I HIGHLY recommend once the old valve is removed completely, do a dry run of mounting the new valve completely disconnected from power and the water lines and REMEMBER how you fit it in as clearance is very tight, once you have everything connected it will be much easier mounting it back in place in/on the refrigerator knowing your path to take as clearance was very tight on my particular install. GOOD LUCK, YOU CAN DO IT !!!
