ActronAir Commercial Outdoor Board CM100 Connectors are the replacement connector components for the CM100 commercial outdoor control board used in Tri-Capacity and Hercules commercial systems, providing the wiring interface connections for compressor, fan, sensor, and BMS signal circuits on the CM100 board assembly. Damaged CM100 connectors cause loss of control signals to compressor and fan circuits, resulting in commercial system lockout or BMS communication failure. Isolate power at mains before replacing any PCB connector components.
