York S1-1474-0061/A Ignition Module

The York S1-1474-0061/A Ignition Module is a critical OEM replacement part designed for use in residential and light-commercial York, Coleman, and Luxaire gas furnaces. This solid-state control board serves as the direct successor and is technically identical to part number 100-00812-45. As a veteran-grade furnace ignition control, it manages the critical intermittent pilot ignition sequence, coordinating the opening of the gas valve with the spark timing to ensure reliable burner ignition. Operating on a standard 24V AC control circuit, this module features built-in diagnostic LEDs to streamline troubleshooting on the job site. It is engineered to handle the thermal stress and vibration common in high-cycle heating environments, preventing common localized failures like nuisance lockouts or short-cycling. For technicians service-calling older DGAM and DGAT series units, this York ignition module replacement provides a drop-in fit with pre-terminated keyed headers, ensuring logic-consistent performance and safety-standard compliance without the need for field modifications.

• Direct Cross-Reference: 100% identical to legacy number 100-00812-45 for immediate drop-in replacement.
• OEM Precision Logic: Maintains factory-spec timing for the ignition sequence and flame sensing.
• Integrated Diagnostics: High-visibility LED indicators provide clear fault codes to reduce diagnostic time.
• Enhanced Durability: Resin-sealed internals protect critical circuitry against moisture and extreme plenum temperatures.
• Wide Compatibility: Validated for use in specific York, Coleman, and Luxaire furnace models, restoring original system performance.

Is the S1-1474-0061/A compatible with older 100-00812-45 modules?
Yes, this is the official manufacturer-designated replacement for the 100-00812-45. It utilizes the same mounting footprint and wiring configuration for a seamless swap.

What safety features are integrated into this board?
This module includes automatic safety lockout protocols and continuous flame monitoring to prevent the gas valve from remaining open if a flame is not detected during the 90-second ignition trial.

Will this resolve a "furnace starts then stops" issue?
If your diagnostics point to a failure in the ignition logic or flame rectification circuit, replacing the module often resolves frequent cycling and pilot ignition failures.
