A refrigerator includes a compressor, an evaporator fan, a condensor fan and a defrost heater which are controlled by a defrost control system. The control senses the number and duration of freezer and fresh food compartment openings, the duration of the previous defrost operation, and the total accumulated compressor run time since the previous defrosting operation. A stored count is decremented by weighting functions which are adaptably varied in accordance with the number and duration of compartment door openings and the duration of the previous defro...


In a cooling system having a defrost device and cooled compartment accessible through a door, a defrost control for energizing the defrost device, comprising: door sensing means for detecting an initial open period for said door and a subsequent open period when said door remains open beyond said initial open period; control means for energizing said defrost device at the end of an interval determined at least partly by the cumulative open period of the door, including: first advance means for advancing toward the end of the interval at a first rate in r...
