Its stainless construction resists the high heat and corrosion inside the combustion chamber, distributing gas evenly across the burner ports for a clean, consistent blue flame. (Note: while this item may be listed under a capacitor category, the \u003cstrong\u003e18P46\u003c\/strong\u003e is a burner cap component.)\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCommon failure symptoms:\u003c\/strong\u003e A cracked, warped, or corroded burner cap can produce yellow or lazy flames, uneven heating, flame roll-out, sooting, delayed or noisy ignition, and nuisance flame-sensor lockouts. Because it sits in the hottest part of the furnace, the cap eventually degrades and needs replacement.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy OEM matters:\u003c\/strong\u003e Lennox sizes the \u003cstrong\u003e18P46\u003c\/strong\u003e to match the exact port pattern and gas rating of its burners, ensuring the correct air-to-fuel mixture and safe, efficient combustion. Aftermarket substitutes can alter flame shape and combustion quality, risking incomplete burning and elevated carbon monoxide. Choosing the OEM part protects performance, safety, and your equipment warranty.\u003c\/p\u003e","brand":"Lennox","offers":[{"title":"Default Title","offer_id":63081129869683,"sku":"LNX-18P46","price":18.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0984\/1190\/5395\/files\/nhvac-burner-ribbon-LNX-18P46.jpg?v=1783763666","url":"https:\/\/nationalhvacparts.com\/products\/oem-lennox-stainless-steel-burner-cap-18p46","provider":"National HVAC Parts","version":"1.0","type":"link"}
