2505-113 Outdoor Axial Fan FC063VDQ6K5L drives condenser airflow across the outdoor coil on commercial package and split ducted systems (PCG, SCA, and Hercules series), rejecting heat from the refrigerant circuit to maintain rated cooling and heating capacity at all operating conditions. This assembly uses a 4P-pole AC 3 Phase AC axial fan motor (FC063VDQ6K5L) 7B -- when the outdoor fan fails, condensing pressure rises rapidly in high-ambient conditions, triggering high-pressure protection and compressor lockout within minutes. Isolate power at mains before replacement -- EC motors and 3-phase components retain dangerous residual voltages after power isolation.
