Lochinvar & A.O. Smith 100112679 Ignitor
When you're troubleshooting a call for heat and find the hot surface ignitor isn't glowing, the Lochinvar & A.O. Smith 100112679 Ignitor is the OEM replacement part required to restore system sequence. This nitride ignitor kit is engineered for high-performance gas water heaters and boilers, providing the thermal durability needed to withstand repeated ignition cycles. As a veteran technician knows, silicon nitride construction offers significantly better mechanical strength and oxidation resistance than older carbide versions, reducing the risk of fracture from vibration or handling. This specific Lochinvar ignitor ensures precise flame ignition for A.O. Smith, State, and Reliance commercial and residential units. Using a genuine factory part like the 100112679 maintains the original HVAC equipment specifications, ensuring the ignition control module detects the correct amperage draw. Avoid the "open" circuit diagnostic codes by installing this direct-fit gas burner igniter, designed to handle the high-input requirements of modern heating systems.
Key Benefits:- Durable Nitride Construction: Superior resistance to physical impact and thermal shock compared to standard carbide ignitors.
- OEM Compatibility: Exact replacement for A.O. Smith and Lochinvar units, ensuring proper fitment and terminal connection.
- Optimized Ignition Cycle: Precise heat-up timing reduces gas valve delay and prevents delayed-ignition "booms."
- Complete Maintenance Kit: Includes necessary mounting hardware and wire leads to simplify field replacement.
What are the signs of a failing 100112679 ignitor?
The most common symptom is a "no-glow" condition during the ignition trial. Visually inspect the element for white silica dust or hairline cracks, which indicate high-resistance points or an open circuit. Always check for 120V at the control board terminals before condemning the part.
Can I touch the ignitor element during installation?
While nitride ignitors are more resilient than silicon carbide, it is still best practice to avoid touching the heating element with bare hands. Skin oils can create hot spots, though this was a more critical failure point for older carbide models.
Does this kit work with both natural gas and liquid propane units?
Yes, as an OEM component, the 100112679 is designed to function within the burner assembly of compatible NG and LP water heaters and boilers, provided the model and serial number match the manufacturer's parts list.
