Product review (5 stars): Very Easy Repair to Fix a non-Functioning Ice Maker
A couple weeks ago, our ice maker stopped making ice.  It filled with water, but would not push the ice out.  Initially I tried unfreezing the water inlet pipe with a hair dryer, and then resorted to replacing the ice maker.  When that didn't work, I replaced the water inlet valve. This did the trick.

The valve was super easy to change out.  using different size tubing and different size wire connectors made getting the correct connections very easy.  I did not require the additional tubing or coupling that came with the valve, nor did I require a trip to Home Depot to get a different adaptor as many folks here mentioned was required.  This took me about an hour from start to finish, and most of that was taking the kitchen apart to move the fridge (don't ask!).

High Points

1) Very Easy to Install (you may want to check out some YouTube how-to videos)
2) Came with everything required to install other than tools
3) Tools needed - 1/4" nut driver, flathead screwdriver, razor blade
4) 1/3 the price at 3 other online parts stores
5) provided an opportunity to vacuum the coils!
