Rheem-Ruud 62-23556-10 Direct Spark Ignitor

The Rheem-Ruud 62-23556-10 Direct Spark Ignitor is a high-precision OEM replacement engineered for reliable ignition in residential and commercial gas furnaces. Designed to provide consistent high-voltage arcing, this direct spark ignition (DSI) electrode ensures efficient combustion startup even in demanding cycles. It serves as a direct replacement for various Protechtor ignition systems and integrated furnace control boards used in Rheem and Ruud heating equipment. Constructed with high-grade ceramic insulation and durable electrode materials, it resists thermal stress and oxidation, preventing common failure points such as cracked insulators or fouled tips. For technicians performing furnace troubleshooting, this component is critical for resolving ignition lockout codes and ensuring the flame rectification signal remains within the required microamp range. Integrating this genuine HVAC replacement part maintains the original equipment’s performance specifications and prevents the premature wear often associated with universal aftermarket ignitors.

• OEM Precision: Guaranteed compatibility with Rheem-Ruud furnace models, eliminating the need for bracket modifications during installation.
• Enhanced Durability: Robust ceramic shielding prevents electrical leakage and withstands high-temperature combustion environments.
• Reliable Arc Generation: Specifically calibrated gap settings provide a consistent spark for immediate fuel ignition.
• Flame Sensing Integration: Functions effectively within the flame rectification circuit to provide accurate feedback to the ignition module.

Is the 62-23556-10 compatible with older spark-to-pilot systems?
No, this is a dedicated direct spark ignitor designed for DSI systems where the main burner is ignited directly by the spark, rather than through a pilot assembly.

What causes this ignitor to fail prematurely?
Failures are typically linked to carbon buildup, cracked ceramic housing due to physical impact, or excessive moisture in the combustion chamber leading to electrical grounding.

How do I test the 62-23556-10 during a service call?
Check for physical cracks in the ceramic and verify the spark gap. Ensure the high-voltage lead is secure and inspect the ignition control board for proper voltage output to the electrode.
