Fenwal 22-100001-372 Electrode

The Fenwal 22-100001-372 Electrode is a critical OEM component designed for high-precision direct spark ignition in commercial and industrial heating applications. As a veteran-grade HVAC replacement part, this electrode is engineered to maintain a consistent spark gap under extreme thermal cycling, ensuring reliable gas furnace ignition or boiler startup. Its ceramic insulator construction prevents high-voltage leakage, while the specialized alloy probe resists oxidation and carbon buildup, common causes of ignition failure. This Fenwal ignition electrode is a drop-in replacement for the 22-100001 series, providing the structural integrity required for HVACR burner assemblies. By replacing worn or cracked electrodes with this genuine part, technicians can eliminate nuisance lockouts and ensure the flame rectification signal remains within specified microamp ranges for the ignition control module.

Key Benefits for Technicians:

• OEM Compatibility: Exact replacement for Fenwal 22-100001-372, ensuring proper alignment within the burner venturi.
• High-Temperature Durability: Robust ceramic insulation prevents electrical tracking and withstands sustained combustion chamber heat.
• Reliable Spark Generation: Designed for rapid direct spark ignition (DSI), reducing fuel accumulation and promoting smooth light-offs.
• Precision Flame Sensing: Maintains accurate flame rectification to provide the control board with a stable signal.
• Simplified Installation: Standard mounting configuration allows for efficient field replacement in commercial heating systems.

Common Questions:

How do I troubleshoot an ignition lockout with this electrode?
Perform a visual inspection for cracks in the ceramic insulator or carbon fouling on the tip. Use a multimeter to verify the flame sensor microamps and ensure the spark gap is set to Fenwal’s factory specifications.

Can this be used for both ignition and flame sensing?
Yes, in many Fenwal DSI systems, this component serves a dual purpose: providing the high-voltage spark for ignition and acting as the sensor for flame rectification after the burner is lit.

What causes these electrodes to fail prematurely?
Failures are typically caused by physical damage during handling, excessive soot buildup from poor combustion air, or mechanical stress from improper mounting in the burner assembly.
