ABSTRACT OF THE DISCLOSURE A single evaporator, single fan combination refrigerator includes a temperature control system which thermostatically maintains the fresh food compartment at a desired temperature by cycling the refrigerator system on and off as required, and which controls freezer compartment temperature by varying airflow thorough a pair of ducts conducting refrigerated air from the evaporator chamber to the fresh food compartment. The freezer control operates a pair of main dampers disposed in the ducts. In order to compensate for variations in freezer compartment temper- ature which would otherwise result when the setting of the thermostatic fresh food control is changed, a pair of compensating dampers are also disposed in the ducts and operatively connected to the fresh food control for ganged operation with the thermostatic control. The dampers are constructed to only partially block airflow when in the fully-closed position. In certain embodiments, selection of damper characteristics is easier than in other embodi- ments, and a method of selection is described.
