To allow for easier opening of a refrigerator door, a pressure relief system is provided to relieve a pressure differential or vacuum that develops due to operation and use of the refrigerator. The pressure relief system includes a check valve having an orifice with a flexible membrane. An insulation portion of the pressure relief valve, which is foamed into the cabinet, spans from the fresh food compartment to a top of the cabinet and directs air towards the rear cabinet liner for moisture condensing measures. The pressure relief assembly also includes an adapter which mounts to the cabinet top and provides a mounting surface for an air return assembly.
