OEM Carrier Fan Timer Control Board 20054502 for Model FPBB100D13CN

This is the genuine OEM fan timer control board (part #20054502) factory-specified for the Carrier FPBB100D13CN fan coil unit. The fan timer control board serves as the operational brain of your system, managing blower fan sequencing, timing delays, and communication between the thermostat and air handler components. When this board fails, symptoms typically include the blower fan refusing to start or stop, erratic fan cycling, system lockout errors, or a complete loss of heating and cooling response at the air handler — even when the thermostat is calling for conditioning.
