OEM Carrier Fan Blower Control Board HK61EA010 for Model FC4DNB060000AAAA

This is the genuine OEM fan blower control board (part number HK61EA010), the factory-specified replacement for the Carrier FC4DNB060000AAAA air handler. The control board serves as the central command module for the blower assembly, managing fan speed staging, timing sequences, and communication with the thermostat and system components. When this board fails, you may experience a blower that won't start, a fan that runs continuously regardless of thermostat commands, intermittent operation, diagnostic fault codes, or a complete loss of heating and cooling airflow — even when the outdoor unit is functioning normally.
