Abstract
Adaptive defrost control and method for a household refrigerator wherein a defrost interval is adjusted based upon the time it takes for a previous defrost cycle to complete. The adaptive defrost control also provides a vacation mode in which the defrost interval is set to an artificially long interval if a door of refrigerator has not been opened for some predetermined period of time. Further a defrost termination thermostat is provided that is stable during power interruption. The termination thermostat is used as a memory device to determine whether a defrost cycle was in process when power was interrupted.
