When I close the door it doesn’t seem to keep the cold air in.

Its possible that the door may be damaged which would prevent it from staying cold. I would suggest ordering another exterior door from the company Frigidaire and replacing the old door. Please see the replacement guide. Frigidaire FFPE45B2QM Refrigerator Door Replacement

Try seeing if the rubber gasket has frayed or bubbled around any part of the door. This is a common Frigidaire Refrigerator Repair especially, for older units or fridges kept outdoors (like mine at home in the garage). Just my 2 cents… -Fred Repair Tech Las Vegas Appliance Repair Expert
