Robertshaw 41-401 Hot Surface Ignitor
For service calls requiring a robust ignition source, the Robertshaw 41-401 Hot Surface Ignitor is the industry-standard silicon carbide solution. Engineered for 120V AC operation, this Carbide Series ignitor features high-purity recrystallized silicon carbide construction, often referred to as Crystar, which provides the thermal stability needed for high-cycle heating applications. This 271A factory-spec component is a direct cross reference for Robertshaw 41-401N and reaches furnace ignition temperature in approximately 17 seconds, ensuring reliable burner light-off in gas furnaces, boilers, and unit heaters. The unit is equipped with 18-gauge nickel-chrome lead wires that are metalized in place for superior conductivity and protected by high-temperature fiberglass insulation. Designed with a Type A ceramic block and Type A terminal connector, it stands as a versatile HVAC replacement ignitor for Amana, Lennox, and White-Rodgers systems.
Key Benefits for the Contractor- Universal Application Compatibility: Replaces a wide range of OEM parts including Amana 10041601, Lennox 96P01, and White-Rodgers 767A-369.
- High-Purity Silicon Carbide Element: Recrystallized carbide provides physical strength and stable resistance values over time.
- Superior Lead Wire Connection: 18-gauge nickel-chrome leads are embedded and metalized to prevent pull-out and maintain electrical integrity.
- Installation Ready: Each unit is boxed with a high-temperature gasket to ensure a proper seal against the burner box.
- Flexible Voltage Handling: While designed for 120V AC, it is compatible with control modules that step down 208/240V input to the ignitor.
Can I touch the silicon carbide element with my bare hands?
No. Skin oils can create hot spots on silicon carbide ignitors, leading to premature failure. Always handle the component by the ceramic base or use clean gloves.
What is the difference between the 41-401 and the 41-401N?
The 41-401 is an original silicon carbide ignitor, while the 41-401N is the silicon nitride upgrade. The nitride version is generally more resistant to physical impact and contamination.
Why is my new ignitor glowing but the burner isn't lighting?
Ensure the ignitor is correctly positioned in the burner stream. If the hot surface ignitor serves as a flame sensor (flame rectification), check for proper grounding and a clean signal back to the control board.
