Silicon nitride ignitors are known for their durability and resistance to thermal shock compared to older silicon carbide designs. This ignitor serves as the ignition source in the burner assembly, generating the heat required to light the gas at startup. It is installed by licensed HVAC technicians during routine service or as a direct replacement for a failed ignitor in a gas furnace or similar heating appliance.\u003c\/p\u003e\u003cp\u003eThe 41-404n is suited for residential and light commercial gas heating applications where a hot surface ignitor is the specified ignition method. It is a common replacement component in gas furnace service work, addressing ignitor failure symptoms such as no-heat calls, failed ignition lockouts, and burner startup faults. Technicians should verify ignitor style, bracket configuration, and electrical connector type before installation to confirm fitment.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSilicon nitride construction offers improved resistance to thermal shock compared to silicon carbide ignitors\u003c\/li\u003e\n\u003cli\u003eDirect replacement style for gas furnace hot surface ignition systems\u003c\/li\u003e\n\u003cli\u003eDesigned for reliable performance in gas-fired heating equipment\u003c\/li\u003e\n\u003cli\u003eCompact ignitor element suited for standard burner compartment installation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement hot surface ignitor for residential and light commercial gas furnace applications requiring a silicon nitride ignitor element.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed HVAC technician in accordance with the appliance manufacturer instructions and applicable local codes. Always shut off gas supply and disconnect electrical power to the furnace before removing or installing the ignitor. Handle the silicon nitride element carefully to avoid contamination from skin oils, and avoid mechanical stress on the element during installation. Consult the furnace wiring diagram and ignitor bracket specifications before completing the replacement.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\u003cli\u003e\n\u003cstrong\u003eIgnitor Type\u003c\/strong\u003e: Silicon Nitride Hot Surface Ignitor\u003c\/li\u003e\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ROBERTSHAW\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 41-404n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ROBERTSHAW","offers":[{"title":"Default Title","offer_id":51467553308978,"sku":"41-404N","price":55.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/313945280.jpg?v=1783906719","url":"https:\/\/voomisupply.com\/products\/robertshaw-41-404n-silicon-nitride-hot-surface-ignitor","provider":"Voomi Supply","version":"1.0","type":"link"}
