This is a bottom freezer refrigerator. First I unplugged the refrigerator. I then removed the wire shelf and wire tray from the freezer. I then removed the ice maker be removing the three screws that hold it in place. I then disconnected the icemaker electrical connector. I then removed the 7 screws that hold the panel at the back of the freezer revealing the evaporator and heat exchanger. I then unclipped the icemaker wiring harness from the panel. The whole evaporator/heat exchanger was buried in ice. I defrosted it with a hairdryer. This took about half an hour. The bi-metal thermostat is attached to the heat exchanger by a clip. Be sure to wear latex gloves to prevent cutting your fingers on the aluminum fins. I disconnected the electrical connectors and then carefully unclipped the thermostat. I discovered that the new thermostat had spade connectors where as the original had one spade connector and a bullet connector on the brown wire. I reused the original bullet connector by cutting it off the old thermostat and splicing it onto the new thermostat. I reversed the process for reassembly. There is no longer any ice build up and the refrigerator is working normally.
