Lochinvar & A.O. Smith 100277283 Ignitor

When you are troubleshooting a no-heat call on a Lochinvar FBN6000 or FBL6000 boiler, the Lochinvar & A.O. Smith 100277283 Ignitor is a high-frequency failure point that requires immediate professional attention. This OEM hot surface ignitor is engineered for high-output gas-fired systems, featuring a 4.03-inch elliptical long element designed to withstand the intense thermal cycling of commercial and residential condensing boilers. As a veteran tech, you know that ignitor resistance drops over time; a cracked ceramic base or a carbon-filmed element will prevent the ignition control board from establishing a stable flame. This genuine replacement ignitor comes with the critical sealing gasket to ensure a gas-tight combustion chamber seal, preventing flame rollout and pressure switch trips. Integrating this 100277283 K igniter ensures your HVAC equipment maintains peak efficiency and prevents unnecessary short cycling or system lockouts during peak demand.

• Direct OEM Match: Specifically engineered for Lochinvar boiler parts compatibility, ensuring correct voltage draw and timing.
• Complete Assembly: Includes the essential mounting gasket (4.03" length) to prevent combustion leaks and air-to-fuel ratio imbalances.
• Durable Construction: High-grade silicon carbide or nitride material designed for rapid heat-up and consistent burner ignition.
• System Reliability: Minimizes diagnostic time and service call-backs by restoring the factory-spec heating furnace ignition sequence.

Is the gasket included with the 100277283 ignitor?
Yes, this assembly includes the specialized gasket required for a secure, airtight seal against the burner plate.

Which Lochinvar models does this ignitor fit?
This part is the primary replacement ignitor for Lochinvar FBL6000 and FBN6000 high-efficiency boiler models.

Can I touch the ignitor element during installation?
No. As a professional, always handle the ceramic base only. Skin oils can create hot spots on the element, leading to premature failure.
