ABSTRACT:
A control circuit for a refrigeration system disposed within an outer cabinet having a freezer compartment, a fresh food compartment, a compressor, a condenser fan, an evaporator fan, an evaporator and a freezer thermostat disposed within the freezer compartment to sense temperature therein. Additionally, a fresh food thermostat is disposed within the fresh food compartment to sense temperature therein. A freezer thermostat switch is switched between an open state and a closed state in response to temperature signals generated from the freezer thermostat. A fresh food thermostat switch is switched between an open state and a closed state in response to temperature signals generated from the fresh food thermostat. An energy saver switch is disposed between the fresh food thermostat switch and a power source, which energy saver switch is switched between an open state and a closed state. If the energy saver switch is disposed in an open position and the fresh food thermostat demands cooling the fresh food switch is switched to a closed position and the compressor and the condenser fan are not energized. If, however, the energy saver switch is disposed in a closed position and the fresh food thermostat demands cooling the fresh food switch is switched to a closed position and the compressor and the condenser fan are energized.
