A refrigerator includes a fresh food compartment, a freezer compartment and a refrigeration system. A duct, exposed to the freezer compartment, leads into the fresh food compartment. A damper is arranged within the duct to selectively allow the passage of cooling air into the fresh food compartment. The refrigerator also includes an air mixing fan arranged in the fresh food compartment, a freezer mounted ice maker, a user interface having a plurality of control elements and a controller operatively associated with the user interface. The controller includes a memory having stored therein a plurality of operating parameters for controlling various aspects or features of the refrigerator, including a temperature control mode, a super cool mode, a food saver mode and a quick ice mode, which can be synergistically combined to efficiently operate the refrigerator.

Control for a refrigerator

A refrigerator includes a fresh food stirring fan assembly arranged within a fresh food compartment. The stirring fan assembly functions to recirculate air in order to minimize temperature stratification in the fresh food compartment. The stirring fan assembly preferably incorporates a filter to remove airborne debris and absorb odors. In accordance with one preferred embodiment of the invention, the fresh food stirring fan is operated whenever a damper controlling an inlet flow of cooling air to the fresh food compartment is in a closed position.

Air circulation and filtration system for a refrigerator

A refrigerator temperature control system includes a passageway for delivering a supply of cooling air from a freezer compartment to a fresh food compartment. A diverter member is positioned about the passageway in the freezer compartment for channeling the air through the passageway. A freezer compartment temperature sensor is routed from a temperature control unit in the fresh food compartment, through a bore formed in an insert which defines the air passageway, into a specialized chamber formed as part of the diverter member. The chamber is in fluid communication with the flow of air to the fresh food compartment through a bleed hole. To increase its surface area, the sensor is preferably coiled within the chamber and an insulation jacket extends about the sensor from within the fresh food compartment, with the insulation jacket creating a seal within the bore. In addition, a supporting sleeve extends about the sensor between the temperature control unit and the coiled portion of the sensor.
