Is this is a bottom mount fridge? Hey if your fridge is a fairly a new one. Say less than 8 years old and a fancy one then this is how it works.
a) Fan in freezer circulates air. Mainly to the freezer compartment.
b) Then for the fridge compartment there is a Vent door operated by a vent motor.
Either this vent motor not working and opening, or it is frozen or the thermister that controls the temperature on Fridge compartment is not asking for cooling and thus not sending power to the vent motor to open.
