Fenwal 22-100001-010 Electrode Assembly

The Fenwal 22-100001-010 Electrode Assembly is a precision-engineered OEM replacement ignition electrode designed for high-performance gas-fired HVAC systems, including industrial furnaces, boilers, and commercial combustion equipment. Built to withstand the rigorous demands of direct spark ignition (DSI) cycles, this Fenwal electrode features high-temperature resistant ceramic insulation and a durable metallic probe to ensure a stable, high-voltage spark for reliable burner start-up. In the field, this assembly is critical for maintaining efficient combustion and preventing nuisance flame failures. Whether you are servicing a commercial boiler ignition system or a standard gas-fired furnace, this genuine HVAC ignition part provides the exact physical dimensions and electrical conductivity required for seamless integration and optimal millivolt signal feedback to the ignition module.

• Direct OEM Compatibility: Engineered as a drop-in replacement electrode for specific Fenwal and Laars heating systems, reducing field modification time.
• High-Temperature Durability: Constructed with industrial-grade materials to resist carbon fouling and thermal degradation in high-cycle environments.
• Optimized Spark Precision: Delivers a consistent high-voltage arc to ensure safe and efficient ignition of natural gas or propane.
• Critical Safety Component: Essential for accurate flame sensing and ignition control stability in demanding industrial applications.

What are the signs of a failing electrode assembly?
Technicians typically look for cracked ceramic insulation, heavy carbon buildup, or a corroded probe tip. If the ignition module is sparking but the burner fails to light, or if the system locks out due to a weak flame signal, the 22-100001-010 may need replacement.

Can I clean the electrode instead of replacing it?
While light carbon can sometimes be removed with a non-metallic abrasive, any cracks in the ceramic or significant pitting on the metal probe require a full Fenwal 22-100001-010 replacement to prevent electrical leakage and ensure system safety.

Does this assembly include the mounting hardware?
This SKU is the electrode assembly itself. We recommend verifying the condition of existing mounting brackets and gaskets during the service call to ensure a gas-tight seal and proper alignment.
