ABSTRACT:
The refrigerator temperature control apparatus includes a damper in a cooled air outlet to a storage chamber. The damper is controlled by means of electromagnets with a temperature detecting portin sensing the temperature in the storage chamber and emitting a high level signal or low level signal in response to a sensed temperature. Two switching portions are connected with the temperature detecting portion so as to energize one or the other of the electro magnets for controlling the movement of the damper.
