ABSTRACT:
The baffle for controlling flow of chilled air through the divider wall between the frozen food and fresh food compartments of a refrigerator is coupled to a motor driven cam which indexes the baffle open or closed in response to commands from a conventional control unit. Electrical switches positioned around the control surface of the cam, actuated successively during rotation of the cam, operate the compressor, evaporator fan and defrost heater synchronously with the baffle to maintain the frozen food and fresh food compartments at desired temperatures and to control defrosting.
