A refrigerator cabinet has a valve controlling the amount of cooled air flowing from a cooling chamber having an evaporator to a fresh food compartment to control the ratio of the air flow from the cooling chamber to a freezer compartment and the fresh food compartment. The valve is retained in a predetermined position at the time of assembly by a duct cover, which is forward of an evaporator cover in the freezer compartment, having a frangible key on its front wall extend through an opening in a disc of the valve. If a user deems the freezer compartment too hot or too cold, a service person breaks the frangible key with pliers, for example, after removing the duct cover and rotates the valve to one of a plurality of selected positions to change the air flow. The dics has a plurality of notches in its periphery for cooperation with a second key on the front wall of the duct cover to hold the valve in its selected position. The spacing of the notches on the periphery is in accordance with various rates of air flow to the fresh food compartment.
