I do not know where any components are located in your refrigerator
but your problem is caused by lack of airflow from the evaporator coil
in the freezer unit into the refrigerator. It could be blocked by ice,
blocked by something in the way of the air channels, or the fan might
be inoperative. Locate the air channels and do whatever is necessary
to get the air moving thru and your problem will be solved.

Thanks but I've already looked to see if there is anything blocking any
vents.
