Abstract

An adaptive defrost control method and device for controlling a damper door during a defrost cycle is provided. Before entering the defrost cycle, the adaptive defrost control logic determines if the damper door is open. If the damper door is open, the defrost cycle is suspended until the door is closed. If the damper door is closed, the adaptive defrost control logic activates a barrier between the damper door motor and a power supply so that the damper door may not be opened during the defrost cycle. After the defrost cycle is completed, the adaptive defrost control logic removes the barrier between the damper door motor and a power supply. The damper door may then be opened and closed as necessary. Accordingly, warm moist air from the defrost cycle does not enter the fresh food compartment.
