York S1-325-42681-000 Ignition Kit

The York S1-325-42681-000 24V Spark Ignition Kit is the professional-grade direct replacement for aging or failed G775RJD-12 and 025-27762-700 ignition controls. As a veteran technician knows, maintaining reliable combustion sequencing is critical for system safety; this kit utilizes advanced flame rectification technology for precise flame sensing, ensuring the gas valve closes instantly if a pilot flame is not detected. This microprocessor-based control operates on 24V AC and is engineered to withstand the rigorous thermal cycling of commercial and residential HVAC environments, supporting gas-fired equipment with firing rates up to 400,000 BTU/hr.

Compatibility is a non-issue with this genuine OEM part, which is purpose-built for York furnace replacement and intermittent pilot ignition systems. It fits a wide range of rooftop units and furnaces, including the BPGM (036-060), D2CG (72), D4CG (90-150), D7CG (36-60), DBUC (072), and DHUC (036-060) series. The kit's universal mounting footprint allows for straightforward field installation, even when replacing older Johnson Controls G770RJA-1 or 325-29012-004 models. By upgrading to this modern York spark ignition kit, you ensure consistent burner startup and eliminate common HVAC ignition failure issues caused by degraded legacy modules.

• Universal Compatibility: Serves as a direct OEM drop-in for multiple legacy York and Johnson Controls ignition modules.
• Enhanced Safety: Features a high-speed 0.8-second flame failure response time to prevent gas accumulation.
• Microprocessor Reliability: Eliminates mechanical failure points found in older analog controls for more stable burner sequencing.
• Simple Integration: Includes standard 1/4" and 3/16" quick-connect terminals designed for existing 24V wiring harnesses.
• Broad Application: Suitable for use with natural gas, LP gas, and mixed gas configurations.

Is the S1-325-42681-000 compatible with older G775 systems?
Yes, this York S1-325-42681-000 is the certified replacement for the G775RJD-12 and G770RJA-1. While the mounting hole spacing may vary slightly (3.375" x 3.50"), the logical wiring and terminal markings remain consistent with the original JCI controls.

Does this kit include a new ground wire?
Proper grounding is essential for spark igniter performance. Many technicans recommend installing an additional ground wire directly to the burner manifold if flame sensing current is below the 0.15 microampere threshold.

Can I use this for both natural gas and LP applications?
Correct. This intermittent pilot ignition control is rated for natural, manufactured, mixed, and LP gas-air mixtures across various York BPGM and D4CG models.
