OEM Carrier Fan Blower Control Board HK61EA002 for Model FA4ANC042010AGAA

This is the factory-original fan blower control board (OEM part number HK61EA002) for the Carrier FA4ANC042010AGAA air handler. The integrated fan control (IFC) board is the nerve center of your air handler — it governs blower motor speed sequencing, heating and cooling delay timings, and communicates fault codes through onboard LED diagnostics. When this board fails, common symptoms include the blower motor refusing to start, running continuously regardless of thermostat demand, erratic multi-speed operation, or a complete system lockout with no response to thermostat signals.

• Specs: OEM part number HK61EA002 | Factory-matched for Carrier FA4ANC042010AGAA air handler | 24V control circuit input | Compatible with single-stage cooling and multi-speed blower motor configurations | Onboard LED fault code indicator for simplified diagnostics
• OEM vs Generic: This is a genuine Carrier OEM board programmed with factory blower delay timings and speed profiles. Aftermarket boards may require manual dip-switch configuration and often lack the precise sequencing needed to protect the compressor and heat exchanger, potentially shortening equipment life.
• Install difficulty: 3/5 — Requires disconnecting low-voltage thermostat wiring, line-voltage blower motor leads, and transformer connections. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, phone camera (photograph all wiring before removal). Turn off power at the breaker AND the air handler disconnect before beginning. Transfer dip-switch settings from old board to new before powering up.
• Warranty: 1-year OEM factory warranty against defects in materials and workmanship. Ships same business day from our climate-controlled warehouse in original manufacturer packaging.
