York S1-325-37335-000 Control Kit

The York S1-325-37335-000 DSI Control Kit is an essential OEM replacement engineered for precise ignition management in gas-fired heating systems. As a veteran-grade Direct Spark Ignition (DSI) control, this kit eliminates the need for standing pilots, utilizing high-voltage sparking to initiate combustion directly at the burner. It serves as a critical furnace control board upgrade or repair solution for compatible York, Coleman, and Luxaire gas furnaces. This HVAC ignition module monitors flame rectification via a dedicated sensor circuit, ensuring the gas valve is only energized when a safe ignition sequence is confirmed. Designed for rugged field performance, the kit often includes necessary wiring harness adapters and mounting hardware to facilitate a clean retrofit. Whether you are troubleshooting intermittent ignition failures or resolving a full system lockout, this York replacement part provides the logic required to orchestrate the inducer motor, ignitor, and gas valve timing for optimized thermal efficiency and safety.

• Direct Spark Ignition Technology: Efficiently initiates the burner sequence without a pilot assembly, reducing gas waste and mechanical failure points.
• OEM Compatibility: This genuine York part ensures exact electrical specs and mounting alignments for S1-325-37335-000 applications.
• Integrated Flame Sensing: Features advanced circuitry to detect flame presence, preventing hazardous gas accumulation during ignition trials.
• Contractor-Ready Kit: Includes the DSI control board and supporting components to streamline the replacement process in the field.

• Does this board replace older Johnson Controls or UTEC modules? Yes, this kit is frequently used to supersede legacy DSI controllers; always verify your specific model number against the factory cross-reference.
• How do I diagnose a failed kit versus a faulty ignitor? Check for 24VAC at the board’s output during the ignition trial; if the board provides power but no spark occurs at the electrode, the issue may be the cable or the ignitor itself.
• What does a steady red LED on the module indicate? A steady red light typically signals internal control board failure, necessitating a full replacement of the unit.
