OEM Carrier Fan Blower Control Board HK61EA006 for Model FH4BNF001000AAAA

This is the genuine OEM fan blower control board (part number HK61EA006), factory-specified for the Carrier FH4BNF001000AAAA air handler. The fan blower control board is the command center of your air handler — it manages blower motor operation, speed selection, and timing sequences for heating, cooling, and continuous fan modes. When this board fails, common symptoms include the blower fan not running at all, running at incorrect speeds, erratic cycling behavior, or a complete loss of system response even when the thermostat is calling for conditioned air.

• Specs: OEM part number HK61EA006 | Factory-matched control logic for Carrier FH4BNF001000AAAA air handler | 24V control circuit compatible | Multi-speed blower motor management with integrated fault protection
• OEM vs Generic: This is a genuine Carrier OEM control board — not an aftermarket substitute. OEM boards retain exact firmware, relay ratings, and terminal layouts. Generic or remanufactured boards often suffer from mismatched timing logic and reduced relay life, risking repeat failures and voided equipment warranties.
• Install Difficulty: 3/5 — Requires disconnecting 120V/240V power at the breaker before beginning. Tools needed: Phillips and flathead screwdrivers, needle-nose pliers, phone or camera to photograph all wiring harness connections prior to removal. Label every connector before disconnecting. If unit has a variable-speed (ECM) motor, confirm board compatibility with motor harness before installation.
• Warranty: 1-year OEM factory warranty against defects. In-stock units ship same business day when ordered before cutoff.

Compatibility: Designed specifically for the Carrier FH4BNF001000AAAA fan coil air handler. Always verify your existing board's part number against HK61EA006 before ordering, and confirm your blower motor type (PSC vs. ECM) matches the board's motor interface. Not sure it fits?
