Report "I have just aquired the fridge. It cools properly and defrosts. It appears some parts are missing in the freezer. There are two rectangular holes in the floor of the freezer just ahead of the evaporator cover. The left one has a broken piece of styrofoam in it that appears to be a duct. The other has nothing. There is a gap below the evaporator cover and I can see the melt water collecter and drain. What is missing? Do you have a part diagram that shows these parts and part numbers?"
