{"product_id":"oem-lennox-hot-surface-ignitor-56w61","title":"OEM Lennox Hot Surface Ignitor — 56W61","description":"\u003cp\u003eThe genuine OEM Lennox \u003cstrong\u003e56W61\u003c\/strong\u003e hot surface ignitor is the component that lights the burners in your Lennox gas furnace. When a heat call is received, the control board sends voltage to the ignitor, which glows red-hot and ignites the gas flowing across the burners. It is engineered to the exact resistance and heat profile Lennox control boards expect, ensuring consistent, on-demand ignition throughout the heating season.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCommon failure symptoms:\u003c\/strong\u003e A failed \u003cstrong\u003e56W61\u003c\/strong\u003e ignitor is one of the most frequent causes of no-heat calls. Watch for the furnace blower running without warm air, a system that locks out after several failed ignition attempts, or a visibly cracked, blistered, or non-glowing ignitor element. These silicon-carbide\/nitride elements are brittle and degrade with normal thermal cycling.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy OEM matters:\u003c\/strong\u003e Aftermarket universal ignitors often carry the wrong resistance or mounting geometry, leading to short cycling, delayed ignition, or premature burnout. The factory \u003cstrong\u003e56W61\u003c\/strong\u003e guarantees the correct fit, electrical characteristics, and safe flame timing for your specific Lennox furnace — protecting both the ignitor and the control board it connects to.\u003c\/p\u003e","brand":"Lennox","offers":[{"title":"Default Title","offer_id":63081102147955,"sku":"LNX-56W61","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-56W61.jpg?v=1783762026","url":"https:\/\/nationalhvacparts.com\/products\/oem-lennox-hot-surface-ignitor-56w61","provider":"National HVAC Parts","version":"1.0","type":"link"}
