White-Rodgers 767A-379 Ignitor

The White-Rodgers 767A-379 is a high-performance silicon carbide hot surface ignitor engineered for reliable 120V gas ignition in light-duty and residential furnace applications. As a direct replacement for Robertshaw 41-603 and Norton 601, this mini-ignitor features a ultra-compact nitride-alternative design that fits tight burner corridors where standard-sized elements often struggle. The unit comes equipped with 7.5-inch (+/- 1") lead wires pre-terminated with a pin harness electrical connector, ensuring a secure, plug-and-play installation for field technicians. Rated for 200°C lead wire insulation, the 767A-379 furnace ignitor provides stable resistance (typically 40–100 ohms) to ensure consistent ignition trials across 15, 17, or 45-second HSI systems. This hot surface ignitor mini is built to withstand extreme thermal cycling, minimizing the high-resistance failures and "hot spot" cracking commonly seen in generic aftermarket ignitors. For contractors, this part is a critical stock item for servicing modern gas furnace ignition systems and York OEM replacements like the 025-33421-000.

• Universal Compatibility: Serves as a primary service replacement for Robertshaw 41-603, Norton 601, and various York/Emerson models.
• Rugged Lead Protection: 7.5-inch leads are insulated to handle up to 200°C, preventing wire degradation in the high-heat combustion zone.
• Precise Electrical Connection: Includes a factory-installed electrical connector to maintain the integrity of the ignition circuit and prevent voltage drops.
• Optimized Ignition Geometry: Compact mini hot surface ignitor profile allows for easy mounting in diverse burner configurations without interfering with flame sensing.
• High Thermal Stability: Engineered for consistent resistance levels during the warm-up cycle to reduce wear on the 120V integrated furnace control board.

How do I test if the White-Rodgers 767A-379 is faulty?
Using a multimeter set to ohms, disconnect the pin harness and check for continuity. A functional 767A-379 should typically read between 40 and 100 ohms; an "OL" reading or extremely high resistance indicates a hairline crack in the silicon carbide element.

Can I touch the ignitor element during installation?
No. Skin oils can create hot spots on the ceramic-carbide surface, leading to premature element failure. Always handle the component by the ceramic base and use gloves if necessary.

What should I check if the new ignitor fails to glow?
Verify that the 120V signal is reaching the ignitor during the trial-for-ignition period. If voltage is present but there is no glow, check for a cracked element. If no voltage is present, troubleshoot the pressure switch and the ignition control module.
