OEM Carrier Fan Blower Control Board Kit 322848-751 for Model FB4ANF036010ABAA

This is the factory-specified OEM fan blower control board kit (part number 322848-751) for the Carrier FB4ANF036010ABAA air handler. The control board serves as the central command module for the blower assembly — managing fan speed stages, coordinating with the thermostat signal, and sequencing heating and cooling operations. When this board fails, you may experience a blower that won't start, runs continuously regardless of thermostat demand, operates at incorrect speeds, or triggers a system fault lockout that no amount of resetting will clear.
