OEM Carrier Fan Blower Control Board HK61EA006 for Model FX4BNF018000AAAA

This is the OEM factory-replacement fan blower control board (part number HK61EA006) designed specifically for the Carrier FX4BNF018000AAAA air handler. The integrated fan control (IFC) board serves as the central command module for the air handler — managing blower motor speed sequences, timing delays, and communication with the thermostat and outdoor unit. When this board fails, common symptoms include the blower not starting, continuous blower operation, no response to thermostat calls for heating or cooling, or erratic fan behavior such as incorrect speed staging.
