OEM Carrier Fan Blower Control Board HK61EA002 for Model FA4ANF018000AGAA

This is the factory OEM fan blower control board (part number HK61EA002) for the Carrier FA4ANF018000AGAA air handler. The control board serves as the command center for all blower motor and fan operations — managing speed selection, timing sequences, and fault detection. When this board fails, you may experience a blower that won't run, a fan that operates at the wrong speed, erratic cycling behavior, or a complete system lockout with no response to thermostat calls. Replacing this board with the genuine OEM part restores factory-programmed logic and ensures compatibility with your existing wiring harness and components.

• Specs: OEM Part Number HK61EA002 | Factory-programmed blower control logic | Compatible 24V control circuit input | Multi-speed fan coordination | Integrated fault detection and lockout reset
• OEM vs Generic: OEM control boards ship with factory firmware and pre-configured timing delays, ensuring exact compatibility with your FA4ANF018000AGAA air handler. Aftermarket boards often require manual DIP-switch configuration and may not replicate all fault codes, leading to misdiagnosis and callbacks.
• Install difficulty: 3/5 — Disconnect all power before beginning. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers, phone or camera to photograph all wiring connections prior to removal. Transfer low-voltage wiring terminals carefully; a wiring error can damage the new board immediately upon power-up.
• Warranty: 1-year OEM factory warranty against defects. Orders placed before cutoff ship same business day from our climate-controlled parts warehouse.

Compatibility: Engineered specifically for the Carrier FA4ANF018000AGAA air handler. Always verify the OEM part number HK61EA002 on your existing board's label before ordering to confirm fitment. If you are unsure whether this board matches your unit, our HVAC parts specialists are available to verify compatibility before you purchase — no guesswork required.
