OEM Carrier Fan Blower Control Board HK61EA006 for Model FY5BNF042L00AAAA

This OEM fan blower control board (part number HK61EA006) is the factory-specified replacement for the Carrier FY5BNF042L00AAAA air handler. The integrated fan blower control board orchestrates all blower motor functions — managing fan speeds for heating, cooling, and continuous circulation modes. When this board fails, symptoms typically include the blower motor not running at all, running continuously regardless of thermostat commands, erratic fan speeds, or the system failing to respond to heating and cooling calls. In some cases, fault LED codes on the board itself will indicate the precise failure mode.
