the light is off when the door is shut
i found a number on the top of the fridge.... CS21B5DW - & 14173395YW
the diagram you presented does not look like my refrigerator's.
sorry took so long to respond. Removed back panel in freezer, it was covered in frost. Defrosted it and dried it thoroughly. When reconnected found that the damper door was not opening to allow cool air to circulate. the spring item#10 on diagram was there but we are thinking that item#3 may not be operating and needs to be replaced. what is the name of this item? It looks like a cylinder wrapped with coils.
