My guess is the water line is frozen at the point it enters the freezer compartment altho the parts diagram doesn't show an ice maker with your particular model... Could be the ice maker was field installed after the refrigerator was first purchased... Suggest using a hair dryer to remove any ice buildup in the water line and if this condition persists then replacement of the water fill solenoid may be necessary... Look for any part numbers on the valve itself to help identify a replacement... Good luck, kooler
