Fenwal 22-100000-540 Ignitor Sensor

The Fenwal 22-100000-540 Ignitor Sensor is a high-performance silicon carbide igniter designed for precise ignition and flame sensing in gas-fired heating systems. Engineered for durability, this hot surface ignitor utilizes a robust ceramic base and specialized terminal connections to ensure consistent performance in high-temperature environments. As a critical HVAC replacement part, it is frequently utilized in commercial and industrial furnaces, boilers, and water heaters. The 120V design offers rapid heat-up times, reaching the required ignition temperature quickly to minimize gas valve dwell time and optimize burner cycles. This gas furnace igniter serves dual functions, acting as both the primary heat source for ignition and a flame sensor to verify combustion stability. Its Fenwal ignition control compatibility makes it a reliable choice for technicians troubleshooting intermittent pilot or direct spark systems requiring precise resistance levels and thermal shock resistance.

• High-grade silicon carbide construction provides superior thermal conductivity and resistance to oxidation.
• Integrated flame sensing capability ensures safety by monitoring the presence of a flame throughout the heating cycle.
• Direct-fit OEM replacement design reduces field installation time and ensures correct alignment within the burner assembly.
• Resilient ceramic mounting block protects electrical leads from extreme temperatures and vibration.
• Compatible with a wide range of Fenwal series gas ignition controls and commercial combustion systems.

Is the Fenwal 22-100000-540 compatible with multiple voltages?
No, this specific ignitor is rated for 120VAC operation and should only be used with controls providing that specific output to avoid premature element failure.

Can I touch the silicon carbide element during installation?
Avoid touching the black element with bare hands. Skin oils can create hot spots on the ignitor sensor, significantly shortening its service life. Always handle the part by the ceramic base.

How do I verify if the ignitor is faulty?
Perform a resistance check using a multimeter. If the igniter shows an open circuit or infinite resistance, the element is cracked or burned out and requires immediate replacement.
