OEM Carrier Fan Blower Control Board HK61EA002 for Model FA4ANF030005AFAA

This is the factory OEM fan blower control board (part number HK61EA002) for the Carrier FA4ANF030005AFAA air handler. The integrated fan control board serves as the command center for your air handler's blower motor operation — managing fan speed sequencing, timing delays, and communication with the thermostat. When this board fails, you may experience a blower motor that won't start, a system that runs continuously without shutting off, erratic fan cycling, or a complete loss of heating and cooling airflow despite the outdoor unit operating normally. Fault indicator LEDs on the board can also go dark or display abnormal blink codes, making diagnosis straightforward before replacement.
