ABSTRACT:
When power is supplied to a refrigerator, the refrigerator control system performs one of two different automatic refrigerator temperature setting operations, depending upon whether it is determined that the power is or is not being supplied following a temporary power failure. That determination is made by sensing an internal refrigerator temperature (i.e., a temperature of the cooling compartment and/or the freezing compartment), and providing a reference temperature based upon a sensed external atmosphere temperature. If the refrigerator temperature is less than the reference temperature, then it is assumed that the power is being supplied following a temporary power failure and an appropriate refrigerator temperature setting operation is performed.
