Fresh food side is frozen. When you turn fresh food side temp to off, you hear the fan turn off and the damper door close. When you turn it up to normal, the fan turns on and the damper door opens and cold air from the freezer comes into the fresh side. It continues to run forever until you turn it back off and fan turns off and damper door closes. Terry
