Ice Maker would not stop making ice.

First, I tested the ice maker "switch" that actually just covers the beam that regulates the ice maker. In the "off" position, it still made ice. Then, I removed the three screws on the cover over the transmitter and disconnected the circuit board at the wire connector. It stopped. After ordering and receiving the new transmitter and receiver boards, I replaced both boards. They are located on either side of the freezer compartment under panels held in place by three screws. Probably saved 150 to 200 bucks.
