OEM Carrier Fan Blower Control Board HK61EA010 for Model FX4CNF030008AAAA

This is the factory OEM fan blower control board (part number HK61EA010) designed as a direct replacement for the Carrier FX4CNF030008AAAA air handler. The integrated fan control (IFC) board manages all blower motor operations including variable fan speeds for heating, cooling, and continuous fan modes. It also coordinates low-voltage thermostat signals, fault detection, and communicates with the condensing unit. When this board fails, common symptoms include the blower not running at all, incorrect airflow speeds, intermittent short-cycling, continuous blower operation regardless of thermostat calls, or a complete loss of system response with no LED fault codes.

• Specs: OEM Part Number HK61EA010 | 120V / 60Hz input | 24V control circuit compatible | Multi-speed PSC or ECM blower motor support | Factory-programmed delay-on and delay-off timing sequences
• OEM vs Generic: This is a genuine Carrier OEM board pre-programmed with the exact timing, speed taps, and fault logic for the FX4CNF030008AAAA air handler. Aftermarket boards may require manual DIP-switch configuration and often lack model-specific fault diagnostics, increasing callbacks and misdiagnosis risk.
• Install difficulty: 3/5 — Requires shutting off all power at the breaker and air handler disconnect before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, phone/camera for wiring documentation, and a multimeter to verify 24V control voltage. Photograph all low-voltage and line-voltage wiring harnesses before disconnecting. Board mounts on existing standoffs — no drilling required.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our climate-controlled warehouse.
