White-Rodgers 768A-845 Ignitor

The White-Rodgers 768A-845 is a high-performance silicon nitride ignitor designed as a direct OEM replacement for Trane and American Standard furnace systems. Engineered for durability, this 80V hot surface ignitor serves as an exact match for the White-Rodgers 768A-5, as well as Trane part numbers IGN00104, X13130524010, and B340970P01. For technicians troubleshooting ignition failure, the 768A-845 is the preferred upgrade over older silicon carbide designs, offering superior resistance to physical damage and high-temperature oxidation. This unit features high-temperature Teflon-coated leads and a 2-terminal AMP receptacle with .084" female sockets to ensure a secure, plug-and-play fit during field installation. When testing for continuity, expect a room temperature resistance range of 11 to 18 ohms. Utilizing nitride construction, this component ensures consistent ignition cycles in high-efficiency gas-fired appliances, maintaining system reliability in demanding residential and commercial HVAC applications.

Key Benefits:

• Exact OEM Compatibility: Serves as a drop-in replacement for Trane IGN00104 and White-Rodgers 768A-5 without the need for mounting bracket modifications.
• Enhanced Durability: The silicon nitride element is significantly less fragile than traditional carbide ignitors, reducing the risk of breakage during handling or installation.
• High-Temperature Leads: Equipped with 5-inch white Teflon-coated lead wires rated for 250°C to withstand internal cabinet heat.
• Reliable Ignition: Designed for 80V furnace systems, ensuring stable performance across thousands of ignition cycles.

Common Questions:

Is the 768A-845 compatible with my Trane furnace?
Yes, if your existing part is labeled as 768A-5, IGN00104, or B340970P01, this is the correct technical replacement.

What is the difference between silicon carbide and silicon nitride?
Silicon nitride ignitors like the 768A-845 are much tougher and more resistant to moisture and vibration compared to older, brittle carbide models.

Can I touch the ignitor element with my bare hands?
While nitride is more robust, it is still best practice for technicians to avoid touching the element to prevent skin oils from creating hotspots that could lead to premature failure.
