When the control board calls for heat, the 19W61 heats up and ignites the gas as it flows across the burners. As one of the most frequently replaced furnace wear parts, a reliable OEM ignitor is essential for consistent, safe startups.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCommon failure symptoms include:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eFurnace blows cold air or produces no heat\u003c\/li\u003e\n\u003cli\u003eIgnitor does not glow when a heat cycle begins\u003c\/li\u003e\n\u003cli\u003eVisible cracks, chips, or a broken element\u003c\/li\u003e\n\u003cli\u003eRepeated ignition-failure lockouts and error codes\u003c\/li\u003e\n\u003cli\u003eClicking from the gas valve with no flame\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eWhy OEM matters:\u003c\/strong\u003e The 19W61 is manufactured to the precise resistance, voltage, and physical dimensions your Lennox furnace requires, ensuring the element reaches ignition temperature within the board's programmed timing window. Generic ignitors often mismatch these specs, causing delayed ignition, premature burnout, or nuisance lockouts. Handle the element only by its ceramic base — skin oils shorten its life. Confirm the part number matches your original before installing.\u003c\/p\u003e","brand":"Lennox","offers":[{"title":"Default Title","offer_id":63081113387379,"sku":"LNX-19W61","price":29.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0984\/1190\/5395\/files\/nhvac-igniter-silicon-nitride-LNX-19W61.jpg?v=1783762016","url":"https:\/\/nationalhvacparts.com\/products\/oem-lennox-hot-surface-ignitor-19w61","provider":"National HVAC Parts","version":"1.0","type":"link"}
