York S1-331-03009-000 Control

Upgrade and maintain system integrity with the York S1-331-03009-000 Control, a specialized 2 Stage Furnace Control board designed for high-performance residential heating applications. This genuine York OEM part serves as the central logic unit for two-stage gas furnaces, precisely managing ignition sequencing, inducer motor speeds, and blower timing to ensure balanced airflow and efficient heat distribution. As a veteran-grade HVAC circuit board replacement, it provides reliable fan control and ignition logic to eliminate common failure points such as erratic cycling or secondary stage failure. Engineered for a direct fit, it allows for streamlined field installation in compatible York, Coleman, and Luxaire systems, maintaining the rigorous safety standards required for high-efficiency operation.

The S1-331-03009-000 ignition control is the direct engineering replacement for several legacy modules, including 031-01290-000, 331-02954-000, 331-09168-000, 18381, and White Rodgers 50A51-242. Its integrated diagnostic LED provides real-time feedback, aiding technicians in rapid troubleshooting of pressure switch, limit, and flame sensor circuits. By regulating the transition between low and high heat stages, this board optimizes fuel consumption and reduces mechanical wear on the inducer and blower assemblies.

Key Benefits

• Dual-Stage Management: Specifically engineered to handle two-stage heating logic for improved comfort and reduced utility costs.
• Direct OEM Compatibility: Replaces older 50A51-242 and 031-01290-000 modules without technical modifications to the chassis.
• On-Board Diagnostics: Features a high-visibility LED fault code indicator for precise identification of system lockouts or sensor failures.
• Industrial Build Quality: Constructed with robust relays and thermal-resistant components to withstand the high-heat environment of the furnace blower compartment.
• Broad Application: Compatible with a wide range of TM8T, TM9T, and TMLT furnace series.

Common Questions

What are the signs that my furnace control board has failed?
Common indicators include a steady red diagnostic light, the blower running constantly without a call for heat, or the furnace failing to initiate the ignition sequence after the inducer starts.

Does this board replace the White Rodgers 50A51-242?
Yes, the S1-331-03009-000 is the direct manufacturer-specified upgrade for the discontinued 50A51-242 model.

Can I use this for a single-stage furnace?
This board is specifically designed for two-stage furnace control logic. Always verify your specific furnace model number and wiring diagram to ensure compatibility with 2-stage staging requirements.
