OEM Carrier Fan Blower Control Board HK61EA006 for Model FB4BSF018L00AAAA

This is the genuine OEM fan blower control board (part number HK61EA006) for the Carrier FB4BSF018L00AAAA air handler. The control board is the brain of your air handler — it sequences blower motor operation, manages multi-speed fan settings, monitors safety inputs, and communicates with the thermostat to deliver precise heating and cooling airflow. When this board fails, common symptoms include the blower not running at all, the fan running continuously regardless of thermostat demand, erratic speed behavior, system lockout codes, or complete loss of function in the air handler.

• OEM vs Generic: This is the factory OEM board, not an aftermarket substitute. Generic control boards frequently carry pre-programmed timing delays and fan speed profiles that do not match Carrier factory specifications, leading to comfort issues, premature motor wear, or tripped safety limits. OEM ensures exact compatibility and full system performance.
