Abstract
An ice maker assembly in a refrigerator freezer includes a fill tube for transporting liquid to a mold. The freezer includes an outer wall spaced apart from an inner wall, with a plenum formed therebetween. An opening is formed within the inner wall, through which the fill tube extends with a clearance. Warm air generated by a defrost cycle passes through the clearance in the inner wall and around the fill tube, thereby warming the fill tube. In addition, the fill tube includes vents formed therein to allow active ventilation of the fill tube and to prevent ice formation within the fill tube.
