OEM Carrier Fan Blower Control Board HK61EA010 for Model FX4CNF036T00AAAA

This OEM fan blower control board (part number HK61EA010) is the factory-specified replacement for the Carrier FX4CNF036T00AAAA air handler. The blower control board serves as the brain of your air handler, orchestrating blower motor speeds, heat sequencing, and communication with the thermostat and outdoor unit. When this board fails, symptoms typically include the blower not running at all, running continuously regardless of demand, incorrect airflow speeds, fault codes displayed at the thermostat, or a complete loss of heating and cooling function even when the outdoor unit is operational.

• Specs: OEM Part Number HK61EA010 | Compatible with R-410A air handler systems | 24V control circuit interface | Multi-speed blower motor control | Factory-matched relay and terminal configuration
• OEM vs Generic: This is a genuine Carrier OEM board, engineered to exact factory specifications for the FX4CNF036T00AAAA. Generic or aftermarket control boards often lack precise relay timing, motor speed calibration, and fault-code compatibility, which can lead to improper operation, voided equipment warranties, or repeat failures.
• Install Difficulty: 3/5 — Turn off all power at the breaker and disconnect the air handler before beginning. Tools needed: Phillips and flathead screwdrivers, needle-nose pliers, multimeter, and camera or phone to photograph all wiring harness connections prior to removal. Transfer wiring harnesses one connector at a time to avoid miswiring. If fault codes persist after replacement, consult the unit's service manual for diagnostics.
• Warranty: 1-year OEM factory warranty against defects in materials and workmanship. Orders placed by 3 PM local time ship same business day from our warehouse.
