My Sub Zero 550 was not holding a stable temperature in the refrigerator compartment. After some research and investigation it looks like the door hangs down slightly and the door fan switch for refrigerator circulation may not always make good contact. I checked on the Sub Zero site and they had no info on the 550 but the 650 seemed similar. The info regarding the door hinges talks about 2 shipping screws in the top and bottom hinges that should be removed. These had been removed from the top hinge on my unit but not on the bottom hinge. Should these screws also be removed from the bottom hinge? What do these shipping screws do?
Thanks, Bob
