A control unit is attached to or embedded within a refrigeration appliance to monitor electric power voltage and / or frequency supplied by the mains. If the unit detects a sag or peak in either the voltage or frequency, the control unit either separates any high demand elements of the appliance from the mains to reduce demand in a sag or energizes the elements in a peak. When the control system separates the refrigeration compressor from the mains, a food spoilage monitoring system monitors the food storage compartments. This system utilizes food industry temperature and time algorithms to ensure the food does not spoil. If food spoilage could occur, the unit re-energizes the compressor to allow it to lower the temperature provided the power is sufficient to operate the compressor unit without damaging it. Once the sensed temperature is restored to a safe level, the unit separates the compressor from the mains.
