Abstract: An icemaker assembly for a refrigerator includes a support bracket having at least one support arm and a rear panel section, a bin slidably attached to the at least one support arm, an icemaker unit having an ice mold is also supported by the at least one support arm within the freezer compartment. The icemaker assembly also includes a fan mounted to the rear panel portion of the support bracket. The fan is selectively operable to direct an airflow onto the icemaker unit in order to speed ice production. Operation of the fan is tied to activation of a water inlet valve. A controller is coupled to the fan and the water inlet valve such that once the water inlet valve opens, fresh water enters the ice mold and the control activates the fan to hasten the production of ice.

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.
