OEM Carrier Fan Blower Control Board Kit 322848-751 for Model FC4BNF036000AAAA

This OEM fan blower control board kit (part number 322848-751) is the factory-specified replacement for the Carrier FC4BNF036000AAAA fan coil air handler. The control board is the command center of your air handler — it orchestrates blower motor speed, thermostat signal interpretation, and system sequencing for both heating and cooling modes. When the board fails, symptoms typically include a blower that won't start, runs continuously regardless of thermostat demand, short-cycles unexpectedly, or causes the entire air handler to go completely unresponsive.

• OEM vs Generic: This factory OEM board is pre-programmed with the exact timing sequences, blower speed profiles, and fault-detection logic required by Carrier.

Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, phone or camera to photograph all wiring harness connections prior to removal. Label each connector before disconnecting. Allow capacitors to discharge fully before proceeding.
