Fagor refrigerator (3FCA-68NFX): no cold air in the refrigerator

I have a Fagor refrigerator (3FCA-68NFX) that has stopped working. To be precise, the freezer is working but there's no cold air in the refrigerator. The fan in the back of the freezer is working, it just seems there's no airflow to the refrigerator, the ventilation grills are unobstructed, but no cold air is coming out.

U may have a duct that goes from the freezer to the fridge that is closed off or u may have a stopped up freon line and if thats the case ur probably going to have to call a tech but check the duct first if u have one in that particular fridge
