White-Rodgers 767A-377 Ignitor

The White-Rodgers 767A-377 Ignitor is a heavy-duty silicon carbide hot surface ignitor engineered for high-demand 120V ignition systems, including furnaces, boilers, and rooftop heaters. This OEM-grade component features a robust N-style mounting block and 4-1/2" leads with a Molex front lock connector (featuring .092" male pins) for secure electrical termination. Designed to withstand extreme operational temperatures, the lead wire is rated for 200°C insulation, ensuring long-term integrity within the burner box. As a direct replacement for 41-410 and various Trane models like B144676P01, this 120V HSI ignitor provides consistent ignition across 15, 17, and 45-second systems. The kit includes ceramic wire nuts to facilitate custom cut-and-strip connections when standard plug-and-play is not an option. Techs should verify that the supply voltage does not exceed 132V and avoid touching the carbide element during installation to prevent premature failure from skin oils.

• Universal Compatibility: Specifically designed to replace the Robertshaw 41-410 and Trane B144676P01, reducing truck stock requirements.
• High-Temperature Durability: Features silicon carbide construction and 200°C rated lead insulation for reliable performance in high-heat environments.
• Efficient Troubleshooting: A standard cold resistance of 40-100 ohms simplifies the diagnostic process for identifying failed ignition modules.
• Secure Connections: Equipped with a Molex 3191-2R1 connector and additional ceramic wire nuts for versatile field installation.

How do I test if my 767A-377 ignitor is bad?
Use a multimeter to measure resistance across the plug. A functional 120V furnace ignitor typically reads between 40 and 100 ohms; an infinite "OL" reading indicates a hairline crack in the element. Always check for 120V at the harness during the ignition trial.

Can I use this for LP and Natural Gas furnaces?
Yes, the White-Rodgers 767A-377 is CSA certified for use with both Liquid Propane (LP) and Natural Gas heating systems.

What causes these ignitors to fail repeatedly?
The most common causes are high line voltage (exceeding 125V), physical impact during maintenance, or oil contamination on the element. Ensure the burner ground is secure to allow for proper flame rectification sensing.
