The most likely problem is ice buildup on the freezer coils
themselves.

It is possible that therefrigerator is cooled by airflow over the freezer

If it is in fact the coil frozen, you also have to find the reason and fix
that. Chances are the defrost cycle is messed up or the evaporator fan is
not blowing properly.
