OEM Carrier Fan Blower Control Board HK61EA002 for Model FC4BNF038000AEAA

This is the genuine OEM fan blower control board (part number HK61EA002), factory-specified for the Carrier FC4BNF038000AEAA fan coil air handler. The integrated fan control (IFC) board is the nerve center of your air handler — it manages blower motor speed sequencing, heating and cooling delays, and communicates with your thermostat to coordinate every stage of operation. Common failure symptoms include the blower failing to start, running continuously regardless of thermostat demand, erratic fan speeds, or a complete system lockout with no response from the air handler. A faulty control board can also trigger nuisance fault codes that mimic other component failures, making accurate diagnosis critical before replacing other parts.

Transfer wiring harnesses one connector at a time to avoid miswiring. Re-enable power only after all connectors are fully seated.
