Silicon nitride ignitors are known for their durability and resistance to thermal shock compared to older silicon carbide designs. This ignitor generates the heat required to ignite the gas burner during each heating cycle. It is typically installed by a licensed HVAC technician as part of routine service or a no-heat diagnosis on a gas furnace.\u003c\/p\u003e\u003cp\u003eThis ignitor is suited for residential gas furnace applications where a hot surface ignition system is used in place of a standing pilot or spark ignition setup. It serves as a direct replacement component in systems that call for a silicon nitride ignitor. Consult the furnace manufacturer's documentation to confirm fitment before installation.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSilicon nitride construction offers improved thermal shock resistance compared to silicon carbide ignitors\u003c\/li\u003e\n\u003cli\u003eDesigned for hot surface ignition systems in gas-fired furnaces\u003c\/li\u003e\n\u003cli\u003eOEM-style replacement form factor for straightforward serviceability\u003c\/li\u003e\n\u003cli\u003eCompatible with standard low-voltage ignition control circuits\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement hot surface ignitor for residential gas furnaces equipped with silicon nitride ignition systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eHot surface ignitors are installed by licensed HVAC technicians. Always disconnect power and shut off the gas supply to the furnace before servicing the ignition system. Handle silicon nitride ignitors carefully to avoid contamination from skin oils, which can shorten service life. Verify the ignitor's electrical resistance and confirm proper seating in the burner assembly before restoring power.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eIgnitor Material\u003c\/strong\u003e: Silicon Nitride\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIgnitor Type\u003c\/strong\u003e: Hot Surface\u003c\/li\u003e\n\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: 41-407n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ROBERTSHAW","offers":[{"title":"Default Title","offer_id":51468626428210,"sku":"41-407N","price":50.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/313945472.jpg?v=1783919293","url":"https:\/\/voomisupply.com\/products\/robertshaw-41-407n-silicon-nitride-hot-surface-ignitor","provider":"Voomi Supply","version":"1.0","type":"link"}
