ABSTRACT:
A mechanism to control air flow between the freezer and fresh food compartments of a refrigerator includes an elongated air flow tube and a flow control housing with mating planar surfaces angled relative to the longitudinal axis of the air flow tube. A mating gasket is positioned between the planar surfaces and joined to each with adhesive. An electrical conductor extends through the air flow passageway in the tube and housing and includes a plug of material around the conductor's protective cover. A recess in the housing mounts the plug with an angled surface of the plug filling a matching interruption in the housing's planar surface to prevent air leaks around the conductor. The housing and plug include cooperating dimples which receive a capillary tube extending through the air passage.
