Have had the Sears repairman come to the house to replace this part in 5 minutes for +$100.. twice. When my dad's stopped working, ordered the part and replaced it myself for the cost of the part and shipping. Use a screw driver to pry the right side of the switch and pull out.

Unplugged the refrigerator. Used small flat head screw driver to push the front tab of the old switch in and pulled it out with pliers. Detached and reattached the wires to the switch. Reinserted back into hole. Plugged refrigerator back in to power. All good.
