“clearance and ventilation additional details This question was answered like this "Thanks for the question. Samsung recommends leaving at least 3/8" at the top and sides and 1" behind the RF23J9011SR for air circulation and to ensure best performance and efficiency." I have a follow up. The clearance of 3/8" at the top is from the height including the door (71-7/8") or just the unit excluding the door (70-3/4")?”
