A frost control system is described for inhibiting and removing frost from the door (8) of a storage locker. Relatively cool air is received by an inlet to the frost control system at an inlet placed above the door. The air is drawn into the system by a blow- er (18a, 18b) which forces the air through the ducts (26, 28) of the system. The air passes through strip heaters (30, 32) within the vertical ducts (26, 28) of the defrost system positioned on either side of the door (8). The warm air is discharged horizontally ac- ross the bottom portion of the door and simultaneously rises creating a blanket of relatively warm air in comparison to the am- bient area. Discharge apertures (36, 28) are included in the ends of the vertical ducts (26, 28) which blow a portion of the warmed air to the base of the door (8) to enhance coverage of the door by the warmed air.
