OEM Carrier Fan Blower Control Board HK61EA006 for Model FB4BNF030015AAAA

This is the genuine OEM fan blower control board (part number HK61EA006), factory-specified for the Carrier FB4BNF030015AAAA air handler. The integrated fan control (IFC) board manages all blower motor operations — including variable fan speeds for heating, cooling, and continuous fan modes — while also coordinating communication between the thermostat and the air handler's internal components. When this board fails, common symptoms include the blower motor not starting, running at the wrong speed, short-cycling, erratic operation, or a complete system lockout with no response to thermostat calls.

• Specs: OEM Part Number HK61EA006 | 24V control circuit input | Multi-speed blower motor control | Factory-programmed timing and delay sequences matched to Carrier FB4BNF030015AAAA specifications
• OEM vs Generic: This is a genuine Carrier OEM board — not an aftermarket substitute. OEM boards arrive pre-programmed with the exact fan delay, speed tap, and fault logic your unit requires. Generic or refurbished boards frequently require manual jumper configuration and carry a higher risk of premature failure or miscommunication with your thermostat.
• Install difficulty: 3/5 — Disconnect power at the breaker before beginning. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers, phone or camera to photograph all wiring connections before removal. Match every wire terminal precisely during reinstallation. A multimeter is recommended to verify 24V control power before powering the system back on.
• Warranty: 1-year OEM factory warranty against defects. In-stock units ship same business day when ordered before 3 PM local time.
