OEM Carrier Fan Blower Control Board HK61EA006 for Model FA4BNC024008AAAA

This is the genuine OEM fan blower control board (part number HK61EA006) for the Carrier FA4BNC024008AAAA air handler. The blower control board is the electronic brain of your air handler — it governs blower motor speed staging, communicates with the thermostat, manages auxiliary heat sequencing, and monitors safety inputs. When this board fails, common symptoms include the blower fan not starting, running continuously regardless of thermostat demand, erratic multi-speed operation, intermittent system lockouts, or a complete loss of heating and cooling airflow even when the outdoor unit is operating normally.
