Genuine Fujitsu 9374433186 Outdoor Condenser Coil is the condenser coil in the outdoor unit, where refrigerant takes in or gives up heat to the outside air. A damaged or leaking coil cannot move heat, so the system loses capacity and refrigerant can be lost. A genuine Fujitsu part is made to the same design as the original, so it goes back in the way the outdoor unit was built.
