On a call for heat, this ignitor glows to a high temperature to light the burners in your Lennox gas furnace, making it one of the most critical components in the ignition sequence. It is a direct replacement for Robertshaw\/White-Rodgers 41-410.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCommon failure symptoms:\u003c\/strong\u003e the furnace clicks and attempts to fire but never ignites, the blower runs cold air, the ignitor no longer glows or glows unevenly, you see hairline cracks in the silicon carbide element, or the unit locks out after several failed ignition attempts.\u003c\/p\u003e\u003cp\u003eSilicon carbide ignitors are brittle and degrade with every heating cycle, so replacement is routine maintenance on aging systems. Choosing the OEM Lennox \u003cstrong\u003e87X84\u003c\/strong\u003e ensures the correct resistance, glow temperature, and connector fit for your specific furnace — generic ignitors often mismatch the control board's timing and shorten service life. Restore reliable, safe ignition with a factory-spec part.\u003c\/p\u003e","brand":"Lennox","offers":[{"title":"Default Title","offer_id":63081131999603,"sku":"LNX-87X84","price":29.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0984\/1190\/5395\/files\/nhvac-igniter-silicon-carbide-LNX-87X84.jpg?v=1783763525","url":"https:\/\/nationalhvacparts.com\/products\/oem-lennox-silicon-carbide-hot-surface-ignitor-4-5-molex-87x84","provider":"National HVAC Parts","version":"1.0","type":"link"}
