White-Rodgers 767A-381 Ignitor

As a seasoned technician, you know that a cracked or failing hot surface ignitor is one of the most common call-outs during heating season. The White-Rodgers 767A-381 is a high-performance silicon carbide ignitor designed for professional-grade reliability in 120V systems. This specific furnace igniter replacement features a 2.5-inch element height and is engineered to reach ignition temperature within 17 to 45 seconds, depending on your specific HSI ignition module. It is a direct functional replacement for Robertshaw 41-605 and 41-406, providing a stable ignition source for furnaces, boilers, and unit heaters. The 7.5-inch lead wires are protected by 200°C rated high-temperature fiberglass insulation to prevent melting and shorting against the heat exchanger. This HVAC replacement part includes a complete installation kit with a pre-installed electrical connector, universal mounting adaptors, and ceramic wire nuts for versatile field wiring. When installing, always handle the unit by the ceramic base to maintain the integrity of the silicon carbide element and ensure optimal hot surface ignition performance.

• Universal Field Compatibility: Designed as a direct replacement for 41-605, ensuring you have the right part on the truck for multiple OEM applications.
• Robust Lead Protection: 7.5-inch leads with 200°C rated insulation provide ample length and thermal protection for tight burner vestibules.
• Complete Hardware Kit: Includes multiple mounting brackets and ceramic wire nuts to adapt to York, Lennox, and Goodman furnace configurations.
• Precise Ignition Timing: Engineered to work seamlessly with 15, 17, or 45-second ignition trials, preventing nuisance lockouts.

What is the correct resistance for the 767A-381?
At room temperature, a functional 767A-381 should typically measure between 40 and 75 Ohms. If your multimeter shows continuity but resistance has doubled from these baseline specs, the element is nearing the end of its service life and should be replaced.

Can this ignitor replace a silicon nitride model?
This is a silicon carbide ignitor. While it can physically fit many systems, it should only be used in 120V applications designed for carbide resistance. Always verify the voltage and control board requirements before substituting nitride with carbide.

Does it matter which way the mounting bracket faces?
Yes. Use the included adaptors to ensure the element is positioned directly in the path of the gas flow. Improper alignment can lead to delayed ignition or "booming" starts that stress the heat exchanger.
