The condenser fan is controlled by the refrigerant high heat pressure and will turn on later when the operating pressure builds up. This feature allows low ambient operation and reduces current inrush at initial power on. Run the air conditioner for 15 minutes; during this time the condenser fan will turn on after the condenser coil warms up.
