OEM Carrier Fan Blower Control Board HK61EA006 for Model PF1MNB042000AAAA

This OEM fan blower control board (part number HK61EA006) is the factory-specified replacement for the Carrier PF1MNB042000AAAA air handler. The integrated fan control (IFC) board serves as the central command hub for the blower assembly — managing blower motor speed sequencing, heat and cool fan delays, and fault detection. When this board fails, you may experience symptoms such as the blower refusing to start, continuous blower operation regardless of thermostat call, intermittent no-heat or no-cool conditions, or a system stuck in lockout with LED fault codes flashing on the board itself.
