Fenwal 22-100001-070 Ignitor Sensor

The Fenwal 22-100001-070 Ignitor Sensor is a critical OEM replacement component designed for flame rectification in high-demand gas-fired heating and HVAC systems. As a genuine Fenwal ignition sensor, this unit is engineered to provide precise flame sensing and reliable ignition feedback, preventing nuisance lockouts and ensuring the safety of the combustion cycle. This sensor is constructed with glazed Alumina ceramics and durable rod materials capable of withstanding operating temperatures up to 2175°F (1190°C), making it a standard for HVAC flame sensor replacement in furnaces, water heaters, and rooftop units.

For veteran technicians, the 22-100001-070 is a go-to solution for flame signal troubleshooting. It supports the flame safeguard circuit by monitoring for a minimum DC microamp signal, typically requiring 1.0 µA or higher for stable operation. This gas burner ignitor sensor is built for seamless compatibility with Fenwal ignition modules, including the 35-65 and 35-66 series, ensuring the ignition control system maintains peak efficiency and professional-grade performance in the field.

• Enhanced Durability: Engineered with high-quality Alumina ceramic insulation to resist carbon buildup and thermal stress.
• Precise Rectification: Optimized for accurate flame presence detection, reducing downtime caused by intermittent signal loss.
• OEM Compatibility: A direct-fit Fenwal genuine part designed to meet strict factory specifications for gas heating equipment.
• High-Temperature Resistance: Certified rod materials support operation in extreme environments up to 2175°F.

• How do I test the flame signal on this sensor? Technicians should use a digital multimeter in series with the sense wire to measure the DC microamp (µA) signal while the burner is active.
• Can this sensor be cleaned? Yes, if carbon deposits are present, the rod can be lightly cleaned with a non-abrasive pad to restore proper flame rectification.
• Is this compatible with remote sense systems? Yes, this single-rod sensor is designed for applications where the flame sensing function is dedicated to a separate probe from the spark electrode.
