OEM Carrier Fan Blower Control Board HK61EA006 for Model FC4CNB054000AAAA

This is the genuine OEM fan blower control board (part number HK61EA006), the factory-specified replacement for the Carrier FC4CNB054000AAAA air handler. The integrated fan control (IFC) board serves as the central brain of your air handler — managing blower motor speed sequencing, heat strip staging, auxiliary heat lockout, and fault code diagnostics. When this board fails, common symptoms include the blower not starting, the system locking out with a flashing LED fault code, erratic fan speeds, or a complete loss of heating and cooling airflow even when the thermostat is calling for operation.

• Specs: OEM Part No. HK61EA006 | Compatible with Carrier FC4CNB054000AAAA air handler | 24V control circuit | Multi-speed blower motor outputs | Integrated fault code LED diagnostics | Factory-wired terminal configuration for plug-and-play replacement
• OEM vs Generic: This is the genuine Carrier factory board — not an aftermarket substitute. OEM control boards carry the exact firmware, relay ratings, and terminal layout engineered for your unit. Generic boards frequently cause nuisance lockouts, mismatched timing sequences, and voided equipment warranties.
• Install Difficulty: 3/5 — Disconnect power at the breaker and verify zero voltage with a multimeter before proceeding. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers, phone or camera to photograph all wiring connections before removal. Note each wire label carefully; incorrect re-termination can damage the new board or downstream components.
• Warranty: 1-year OEM factory warranty against defects in materials and workmanship. In-stock and ships same business day from our climate-controlled warehouse.

Compatibility: Designed and factory-matched for the Carrier FC4CNB054000AAAA air handler. Always confirm your existing board's part number (printed on the board label) matches HK61EA006 before ordering. If your data plate or board label shows a different suffix, contact our fitment team — we verify compatibility before your order ships so you get the right part the first time.
