Product review (5 stars): Easy to replace and no problems after I did it
I ended up buying this and the water valve/solenoid assembly to fix my problem.  Turns out it was the icemaker that was indeed the problem.  This replacement did the trick.  Just two screws and a quick disconnect of the wiring harness and it's out.  Putting it back in was just as easy.  Solid buy and will save you money from paying a lot extra for a service call.
