Its insulation and connectors are rated for the heat and voltage found near the burner assembly, where ordinary wire would quickly degrade.\u003c\/p\u003e\u003cp\u003eWhen an ignition wire begins to fail, you may see intermittent or no ignition, repeated ignition-lockout error codes, delayed light-off with a small \"whoomp\" on start, or visible cracking and burn marks on the insulation. Loose or corroded terminals can create a weak spark that leaves the furnace unable to reliably light.\u003c\/p\u003e\u003cp\u003eUsing an OEM Lennox \u003cstrong\u003e25W57\u003c\/strong\u003e guarantees the correct length, terminal style, and high-temperature rating for a direct, no-splice fit in your Lennox furnace. Off-brand leads can arc, melt, or lose connection over time. Replacing with the factory part restores dependable ignition and protects the surrounding components from heat damage.\u003c\/p\u003e","brand":"Lennox","offers":[{"title":"Default Title","offer_id":63081134391667,"sku":"LNX-25W57","price":19.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0984\/1190\/5395\/files\/nhvac-igniter-silicon-carbide-LNX-25W57.jpg?v=1783762135","url":"https:\/\/nationalhvacparts.com\/products\/oem-lennox-ignition-wire-25w57","provider":"National HVAC Parts","version":"1.0","type":"link"}
