Robertshaw 41-406 Hot Surface Ignitor

The Robertshaw 41-406 Hot Surface Ignitor (Manufacturer Model 271Y) is a professional-grade heating system component engineered for high-performance ignition across a wide range of HVAC applications, including furnaces, boilers, and unit heaters. This Norton hot surface ignitor is constructed from high-purity recrystallized silicon carbide (Crystar™), which provides the necessary thermal strength and stable electrical properties required for consistent service in demanding environments. Designed to reach effective ignition temperatures within a 17-second window, this 120V carbide ignitor ensures reliable combustion cycles. This unit features 18-gauge nickel chrome lead wires that are metalized in place for superior conductivity and structural integrity. The 10.5-inch leads are wrapped in high-temperature fiberglass insulation to prevent electrical failure or shorting under intense heat. The Style E ceramic block measures 1-7/8 inches wide, facilitating a standard fit for technicians replacing OEM 271Y furnace ignitors or cross-referencing with Norton 201Y and Honeywell Q4100C9050/U models.

• OEM Compatibility: Serves as a direct-fit replacement for multiple brands, including American Water Heater, Lochinvar, and Norton model 271Y.
• Durable Construction: High-purity silicon carbide material resists thermal shock and physical degradation common in high-cycle heating equipment.
• Industrial Lead Protection: Fiberglass-insulated 18-gauge nickel chrome wires provide maximum electrical protection in tight, high-heat furnace cabinets.
• Precision Timing: Engineered to achieve ignition temperature in 17 seconds, maintaining system efficiency and reducing unburned gas buildup.

Is the Robertshaw 41-406 compatible with 240V systems?
While some ignition modules are rated for 208/240V input, they typically step the voltage down. This ignitor is specifically designed to operate at 120V AC.

What is the correct lead wire length and connector type?
The 41-406 features 10-1/2 inch leads and is designed without a pre-installed terminal connector, allowing for versatile field termination depending on the specific equipment requirements.

Can I touch the silicon carbide element during installation?
No. Skin oils can create hot spots on the silicon carbide surface, leading to premature failure. Always handle the ignitor by the Style E ceramic block or use clean gloves.
