Product review (4 stars): Dropped right into my Viking fridge and saved me a bundle! BUT slow to cycle; EZ fix though
Replaced a broken ice maker in my Viking bottom freezer fridge.  I did have to swap out the full bin sensor bale and transfer a couple of clips off the old unit as well as re-use the wiring harness but even so the entire repair was done in about 15 minutes. Aside from those clips, harness, and the bale the ice maker itself is identical to the original. Now its making ice just fine. All at a fraction of the price of  "Viking" parts which aren't made by Viking anyway!

Why only four stars? Because these types of ice makers use a thermostat to initiate cube harvest and re-start the entire cycle. At a certain temperature it starts things off.  Turns out this model's t'stat kicks things off at 12 deg, not the ususal 17 deg. This made it slow to cycle in my fridge, but I swapped the t'stat out with the one from the old ice maker ( very simple operation using only a phillips head screwdriver ) and things are up to speed now. Still a great deal on an ice maker, but too bad it is so slow to cycle because of the extra-cold initiation point. Maybe your freezer is colder and it will work fast enough for  you... or maybe you can just use your old t'stat like I did... Also replacement t'stats are about 10 bucks right here on Amazon.

Another heads up: The test points between L and M measure 72 ohms on this model, not the generaly stated 4-8 k ohms.

The supplier answered my questions promply and accurately. Very good customer service!
