Ice maker stopped making ice.

I first removed the power cord of the refrigerator from the receptacle. I then removed the screws (3 each) from both the emitter and receiver face plates with a phillips screw driver. I than carefully removed the connector to the each of the circuit boards. A simple pull maneuver. I removed the circuit boards from the face plates. I took the new parts and put them back in reverse order. I put the power cord back in the receptacle.
