OEM Carrier Fan Blower Control Board HK61EA002 for Model FA4ANC036010AGAA

This is the factory OEM fan blower control board (part number HK61EA002) for the Carrier FA4ANC036010AGAA air handler. The blower control board serves as the command center for your air handler's fan operation — regulating blower motor speeds, interpreting thermostat signals, managing heating and cooling delays, and monitoring safety inputs. When this board fails, symptoms typically include a blower that won't start, a fan that runs continuously regardless of thermostat demand, erratic or incorrect airflow speeds, or an air handler stuck in a fault lockout condition with diagnostic LED codes flashing.

• OEM vs Generic: This is a genuine Carrier OEM board, manufactured to exact factory specifications. Aftermarket boards often lack proper speed tap calibration for ECM or PSC motors, resulting in reduced efficiency, comfort complaints, or premature motor failure. OEM is always the safest choice for control board replacements.
