Genuine Daikin 2088020 Outdoor Cross-Fin Condenser is the cross-fin condenser coil in the outdoor unit that releases the system's heat to the outside air as refrigerant passes through it. When it is damaged, blocked, or leaking, the unit can lose output, run hot, or lose refrigerant. A genuine condenser fits and performs the way your Daikin expects — where a non-genuine part can restrict flow or fit poorly.
