Abstract
A temperature control system for a refrigerator including a roll-bonded evaporator in the fresh food compartment in which is formed a non-refrigerant carrying passageway extending the full width of the evaporator. A temperature control located in the compartment includes a temperature sensitive capillary tube portion extending substantially the full length of the passageway so as to be subjected to the limited environment of the passageway and accordingly responsive to the true temperature of the evaporator.
