I ordered a new defrost thermostat and new defrost heater. Two mechanically minded friends did most of the work while I relayed info from the video. They took everything apart as instructed and got to the coils for the ice maker that were frozen. We gently thawed everything in order to remove the heater coils and defrost thermostat. Replacement took a bit as we had to get zip ties from my utility room to reattach the heater coils (part 242094802) around the evaporator. It would have been helpful to have had a video for that aspect, too but we figured it out. When mounting with zip ties they need to be flush in order to get the housing to slide over the coils. They then attached the new defrost thermostat (part 5303918810) and plugged it into the new defrost heater. They put everything back together and when I awoke this morning I had ice.
