White-Rodgers 768A-844 Ignitor

The White-Rodgers 768A-844 is a professional-grade silicon nitride ignitor designed for high-demand 80V furnace ignition systems. As a direct 768A-4 OEM replacement, this component features a robust nitride element that handles high-temperature cycling better than traditional silicon carbide alternatives. For service technicians, the 768A-844 offers a precise fit for Lennox 41K5601 and Rheem 62-24134-02 units, ensuring streamlined field repairs. The assembly includes 15.5-inch Teflon coated leads and a 2-terminal AMP receptacle with .084 female sockets, maintaining the integrity of the original factory wiring harness. This hot surface ignitor is engineered for localized heat concentration, providing reliable gas ignition in residential furnaces and commercial water heaters. When performing a furnace ignitor continuity test, this nitride element typically registers between 30 and 200 ohms, indicative of its high-performance material composition. Its steatite insulator and zinc-plated steel mounting tabs provide the physical stability required to withstand the mechanical vibrations of industrial gas burners.

• Universal Compatibility: Engineering identical to the White-Rodgers 768A-4 and serves as a verified replacement for various Lennox and Rheem ignition modules.
• Enhanced Durability: Silicon nitride construction provides superior resistance to oxidation and physical damage compared to standard carbide ignitors.
• OEM-Spec Leads: Factory-installed 15.5-inch high-temperature leads with an AMP connector eliminate the need for field splicing or re-pinning.
• 80V Performance: Specifically tuned for 80-volt ignition systems, ensuring rapid heat-up times and consistent burner light-offs.

• Is the 768A-844 interchangeable with the 768A-4? Yes, the 768A-844 is the latest technical designation for the original 768A-4 and functions as the direct OEM replacement.
• Can I touch the nitride element during installation? While nitride is more durable than carbide, it is best practice to avoid touching the element with bare hands to prevent skin oils from creating hot spots.
• How do I test if this part has failed? Use a multimeter to check for continuity across the 2-terminal plug; a reading with no resistance generally indicates a fractured or burnt-out element.
