Silicon nitride ignitors are known for their durability and resistance to thermal shock compared to older silicon carbide designs. This ignitor generates the surface heat required to light the burner on direct-ignition furnaces and is a standard replacement component installed by licensed HVAC technicians during heating season service calls or system repairs.\u003c\/p\u003e\u003cp\u003eThe 07 68a842s1 is suited for residential gas furnace applications where a direct-spark or hot-surface ignition system is used. It fits into the burner assembly and is wired into the furnace control board circuit. This type of ignitor is commonly replaced during routine maintenance, after a no-heat call, or when diagnostic codes indicate an ignition failure. Installation is typically performed by a licensed HVAC technician.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSilicon nitride construction for improved thermal shock resistance over silicon carbide ignitors\u003c\/li\u003e\n\u003cli\u003eHot-surface ignition design for reliable direct ignition of gas burners\u003c\/li\u003e\n\u003cli\u003eOEM-style replacement for straightforward serviceability\u003c\/li\u003e\n\u003cli\u003eCompatible with standard low-voltage furnace control board ignitor 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 using direct hot-surface ignition systems.

Always shut off power to the furnace at the disconnect and close the manual gas shutoff valve before replacing the ignitor. Handle the silicon nitride ignitor carefully to avoid cracking the element, and avoid touching the ignitor surface with bare hands as skin oils can reduce service life. Verify correct fitment and secure all wire connections before restoring power and gas to the system.\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: WHITE-RODGERS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 07 68a842s1\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WHITE-RODGERS","offers":[{"title":"Default Title","offer_id":51162009862450,"sku":"07 68A842S1","price":49.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/306256299.jpg?v=1778888534","url":"https:\/\/voomisupply.com\/products\/white-rodgers-07-68a842s1-nitride-ignitor","provider":"Voomi Supply","version":"1.0","type":"link"}
