York S1-331-01135-000 Ignition Control

The York S1-331-01135-000 Ignition Control is a critical OEM replacement part engineered for high-performance furnace operation within York, Coleman, and Luxaire systems. As a veteran-grade integrated furnace control board, this module serves as the central intelligence for the heating cycle, managing the precise timing of the hot surface ignitor, gas valve sequence, and blower motor speeds. It prioritizes system safety by continuously monitoring flame rectification currents and safety limit strings, including pressure switches and rollout sensors. Designed for seamless HVAC circuit board replacement, it features standard terminal designations for straightforward wiring in the field. This Source1 ignition control is built to withstand thermal cycling and electrical fluctuations, ensuring the ignition sequence remains stable under demanding residential or light commercial conditions. When troubleshooting York furnace error codes, this board’s diagnostic LED provides immediate feedback to pinpoint issues like weak flame signals or open limits, reducing diagnostic time for onsite contractors.

• Universal OEM Compatibility: Provides a direct-fit solution for numerous York, Coleman, and Luxaire furnace models, ensuring exact electrical specifications are met.
• Advanced Diagnostics: Features an onboard LED flash code system to quickly identify ignition lockout, pressure switch failure, or polarity issues.
• Integrated Logic: Manages both the combustion blower and main indoor fan, optimizing airflow timing for maximum heat exchanger efficiency.
• Robust Flame Sensing: Superior flame rectification circuitry prevents nuisance outages and ensures stable burner operation throughout the heating cycle.

What does a rapid red flash on this ignition module indicate?
A rapid red flash typically signifies a twinning error or incorrect 24V phasing. Check your twinning wiring and ensure the transformer polarity is consistent across both boards.

Can the S1-331-01135-000 replace older York control boards?
Yes, this is an upgraded Source1 replacement for several legacy York part numbers. Always verify the specific terminal markings on the field unit against the provided wiring diagram.

How do I resolve a 'low flame signal' error code?
First, clean the flame sensor with a non-abrasive pad. If the signal remains below 1.5 microamps, check for proper gas pressure or a grounding issue before replacing the control board.
