York S1-431-01972-100 Furnace Control Kit

The York S1-431-01972-100 Furnace Control Kit is a professional-grade integrated ignition control designed to serve as the central logic unit for a wide range of York, Coleman, and Luxaire gas-fired furnaces. This kit is a critical HVAC replacement part that manages complex burner sequences, including the inducer motor draft, igniter warm-up, and gas valve regulation. By monitoring flame sensors and limit switches, it ensures safe and efficient combustion cycles. As a high-performance furnace circuit board, it features advanced onboard diagnostics with LED fault codes to streamline troubleshooting for service technicians. This OEM furnace control board is engineered for high-cycle reliability and serves as a verified direct replacement board for multiple legacy part numbers, including 031-01140-002, 031-01933-000, and S1-2702-310P. It integrates seamlessly into existing wiring harnesses to restore full system communication and blower motor timing.

• Universal Compatibility: Serves as a direct-fit replacement for several obsolete York and Coleman control boards, reducing the need for extensive field modifications.
• Advanced Diagnostics: Features an onboard LED indicator that provides real-time fault codes, such as pressure switch failures or limit trips, to significantly cut down diagnostic time.
• Precise Ignition Sequencing: Optimizes the timing for hot surface igniters and gas valve activation to ensure consistent burner transition and heating efficiency.
• Integrated Blower Control: Manages both heating and cooling fan speeds, ensuring correct airflow across the heat exchanger to prevent overheating.
• Rugged Construction: Built with industrial-grade relays and circuitry to withstand the high-temperature environment of a furnace vestibule.

What does it mean if the LED on the S1-431-01972-100 is flashing?
The blinking LED provides specific diagnostic codes. For example, 3 red flashes typically indicate a pressure switch that failed to close, while 4 flashes often point to an open primary limit switch or a blown fuse on the board.

Can this board be used with non-York furnaces?
While primarily designed for York-family equipment (York, Coleman, Luxaire), this integrated furnace control may work with other brands if the wiring pinouts and voltage requirements match, though verifying the specific cross-reference is mandatory.

Is this a direct replacement for part 031-01140-002?
Yes, the York S1-431-01972-100 is specifically designated as the modern replacement for that part number, often including updated logic for better safety and performance.
