I have an Eaton-Viking fridge

Question

I have an Eaton-Viking fridge at my cottage in Canada. It freezes some things in the refrigerator and needs a new temperature control. I understand these fridges were made by some other company such as Amana, GE etc. This appliance is quite old but is in good working order except for the temperature comtrol. Is there any possibility that a part to fit this appliance is still available. The model# is R213F, serial #2091241
