OEM Carrier Fan Timer Control Board 20054502 for Model FPBA050D13CN

This OEM fan timer control board (part number 20054502) is the factory-specified replacement for the Carrier FPBA050D13CN packaged unit. The fan timer control board serves as the central command module for your system — orchestrating ignition sequencing, blower timing, inducer operation, and safety circuit monitoring. When this board fails, common symptoms include the system failing to heat, the blower fan running continuously or not at all, repeated lockout codes, or erratic cycling that no thermostat adjustment can resolve. Replacing the board with an OEM-matched unit restores factory-programmed timing delays and safety thresholds that aftermarket boards may not replicate accurately.

Photograph all wiring harness connections before removal. Observe proper static discharge handling. If multiple error codes are present, verify upstream component health before board replacement.
