767A-371 Gas Furnace Igniter — VNWIQ
The 767A-371 is a silicon carbide hot surface ignitor designed for Robertshaw and Nordyne family units, including Amana, LB White, Coleman, Norton, York, and several others. It features upgraded materials and an anti-aging testing process and is capable of reaching ignition temperatures quickly, typically within about one minute. This product is best for homeowners with Robertshaw/Nordyne-based furnaces seeking a direct replacement that matches common part numbers like 767A-371, 271W, and 62-22441-01.
Best for: Homeowners needing rapid ignition for widely used Robertshaw/Nordyne configurations. Choose this if your furnace model list includes 767A-371 or 271W and you require a straightforward fit with minimal wiring changes.
Caution: The igniter may discolor over time as part of normal aging; discoloration does not necessarily indicate failure but can accompany long-term operation.
62-22868-93 Furnace Ignitor — Funmit
The Funmit 62-22868-93 is positioned as a universal hot surface ignitor compatible with Goodman, Rheem, Ruud, and Weatherking brands. It replaces several part numbers (including 62-22441-01 and 62-22548-01) and uses silicon carbide to deliver fast ignition through a reliable ceramic base with secure wire connections. It’s a strong pick for mixed-brand systems in households or small shops that require a versatile, single replacement part.
Best for: Homeowners with multiple furnace brands in a single house or a service technician handling diverse units. An ideal choice when you need a single part to match several OEM numbers.
Limitation: Compatibility notes indicate some exclusions (e.g., not suitable for certain drum-type furnaces). If in doubt, verify the exact OEM compatibility list before purchasing.
767A-380 Hot Surface Ignitor — White-Rodgers
The White-Rodgers 767A-380 is a 120V silicon carbide hot surface ignitor. It features a 6.125″ lead length and is marketed as a reliable ignition source with 200-degree insulation. This product is well-suited for compatible White-Rodgers or similar OEM configurations where a straightforward, conventional lead length is preferred.
Best for: Systems designed around White-Rodgers or closely matched 767A-380 replacements requiring a shorter lead length for clean, uncomplicated wiring.
Caution: Lead length and mounting compatibility should be confirmed against your furnace layout to avoid tight fits or wiring strain.
Robertshaw 41-408 Hot Surface Igniter
The Robertshaw 41-408 is crafted from high-purity recrystallized silicon carbide, combining physical and thermal strength with stable electrical properties. It is designed to reach ignition temperatures quickly, typically within around 17 seconds, supported by robust 18-gauge nickel-chrome lead wires embedded for reliability. This option is a solid match for Robertshaw systems that require a precise, durable ignition element.
Best for: Furnaces that rely on precise ignition timing and strong electrical connections, especially in Robertshaw-based setups where rapid ignition is essential.
Limitation: As with any silicon carbide igniter, long-term aging and heat cycling can influence performance; ensure correct model compatibility to avoid mismatches.

Buying Guide
Key purchase considerations:
- Compatibility: Verify furnace brand, model, and OEM part numbers to avoid mismatch. Look for replacements that list your exact compatibility or compatible cross-reference numbers.
- Ignition speed: Silicon carbide igniters typically heat quickly; confirm expected ignition times if you need faster starts.
- Lead length and mounting: Ensure lead wires and mounting positioning fit your furnace cabinet and wiring harness without strain.
- Durability: SiC igniters tolerate heat cycles well, but long-term aging can occur. Consider brands offering warranties or robust construction.
- Warranty and returns: Preference for parts with clear return policies or warranties can save downtime if a replacement fails.
FAQ
- What is a silicon carbide hot surface ignitor used for?
– It ignites the gas furnace burner by using rapid heat to light the gas for combustion. - How do I know if I need a direct replacement or a universal ignitor?
– Check your furnace model’s OEM part numbers and compatibility notes; if your unit uses a common cross-reference, a universal ignitor can work. - Can ignitors be used across different brands?
