{"product_id":"oem-lennox-hot-surface-ignitor-80m29","title":"OEM Lennox Hot Surface Ignitor — 80M29","description":"\u003cp\u003eThe genuine OEM Lennox \u003cstrong\u003e80M29\u003c\/strong\u003e is a hot surface ignitor (HSI) that lights your furnace burners at the start of every heating cycle. When the control board calls for heat, current passes through the ignitor element and heats it to a glowing temperature hot enough to ignite the gas as the valve opens. It is a direct-fit replacement engineered to the exact resistance and mounting specification of your Lennox furnace.\u003c\/p\u003e\u003cp\u003eA failing hot surface ignitor is one of the most common causes of a no-heat furnace. Watch for an ignitor that no longer glows, visible cracks or hot spots on the element, a furnace that clicks but never lights, or repeated ignition lockouts after several failed attempts. Because the element is brittle, it can also fail from age, moisture, or vibration.\u003c\/p\u003e\u003cp\u003eThe OEM Lennox \u003cstrong\u003e80M29\u003c\/strong\u003e is matched to the correct voltage, resistance, and glow temperature your furnace's control sequence expects. Universal ignitors often need adapter brackets, run hotter or cooler than spec, and burn out prematurely. A genuine OEM ignitor drops in cleanly, ignites reliably on the first try, and preserves your Lennox warranty for a low-cost, high-impact repair.\u003c\/p\u003e","brand":"Lennox","offers":[{"title":"Default Title","offer_id":63081094513011,"sku":"LNX-80M29","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-80M29.jpg?v=1783762031","url":"https:\/\/nationalhvacparts.com\/products\/oem-lennox-hot-surface-ignitor-80m29","provider":"National HVAC Parts","version":"1.0","type":"link"}
