I found this bit of info which helps me & may be of useful knowledge to anyone on this subject of thermostat controls in fridges.
"The first thing you need to know in order to understand what these controls really do is that all the cold air in the entire refrigerator is made in the freezer compartment. A portion of that cold air is then blown into the fresh food compartment. How much cold air gets blown in is controlled by the "freezer" control, which is really just an air baffle that opens or closed to let more or less air into the fresh food compartment. The "refrigerator" control is actually a thermostat that feels the temperature inside the fresh food compartment and turns the compressor on and off according to the temperature that the thermostat feels."
