Product review (2 stars): Worked fine for about 2 days and then my system stopped ...
Worked fine for about 2 days and then my system stopped making ice. When I discovered this, I manually closed the flapper at the left of the freezer and the red led on the light kept flashing. The pulled the actual ice maker out and inspected it and found no issues. Since I still had my old control boards I decided to re-install them one at a time. I started with the larger of the two. I closed the door and  walked away. Within an hour or so, my system started making ice again and when I would manually close the flapper, the led would stay red solid. Looks like I got lucky on the first try and it appears that only the larger of the two boards is defective.
