OEM Carrier Fan Blower Control Board HK61EA006 for Model FA4CNF030000AAAA

This is the factory OEM fan blower control board (part number HK61EA006) for the Carrier FA4CNF030000AAAA air handler. The integrated fan control (IFC) board is the central command module of your air handler — it sequences the blower motor through heating, cooling, and continuous fan operation modes, monitors safety inputs, and manages variable-speed or multi-speed motor operation. When this board fails, common symptoms include the blower not starting, the system failing to respond to thermostat calls, erratic fan speeds, stuck-on blower operation, or diagnostic fault codes flashing on the LED indicator.

• OEM vs Generic: This is the genuine Carrier OEM board — not an aftermarket clone.

Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers, phone or camera to photograph all wiring harness connections before removal. Label every connector. Static discharge precautions recommended when handling the board.
