OEM Carrier Fan Blower Control Board HK61EA006 for Model FA4BNF030008AAAA

This is the factory OEM fan blower control board (part number HK61EA006) designed as a direct replacement for the Carrier FA4BNF030008AAAA air handler. The blower control board serves as the brain of your air handler's blower assembly — managing fan speeds, coordinating with the thermostat signal, and sequencing blower operation across heating, cooling, and continuous fan modes. When this board fails, common symptoms include the blower motor not starting, fan running continuously regardless of thermostat commands, erratic or incorrect speed selection, or a complete system lockout with no airborne error codes to guide diagnosis.

• OEM vs Generic: This is a genuine Carrier OEM board programmed with factory firmware and calibrated timing sequences. Aftermarket boards may lack correct speed profiles or proprietary communication protocols, leading to reduced comfort, short-cycling, or voided equipment warranties.
• Install difficulty: 3/5 — Disconnect power at the breaker before beginning. Tools needed: Phillips and flathead screwdrivers, needle-nose pliers, phone or camera to photograph all wiring harness positions before removal. Label every connector. Allow 30–60 minutes for a careful swap. If the unit has a variable-speed ECM motor, verify dip switch settings match the original board configuration.
