Positioned precisely at the burner, the electrode arcs to ignite the gas as it flows, initiating warm-up on every call for heat. Correct electrode gap and placement are essential for consistent, on-demand ignition in your Lennox system.\u003c\/p\u003e\u003cp\u003eWhen this ignitor fails, the furnace will click or attempt to spark but fail to light, ignite inconsistently, or lock out after several failed tries — leaving you with no heat. Cracked ceramic insulators, an eroded electrode tip, or a widened spark gap are typical failure points after extended use.\u003c\/p\u003e\u003cp\u003eThe OEM Lennox \u003cstrong\u003e83L71\u003c\/strong\u003e assembly arrives with the exact electrode geometry, ceramic insulator, and mounting bracket specified for your unit, so it drops into place and sparks at the correct gap. Off-brand igniters often mis-position the spark or degrade quickly. Install the factory part for dependable ignition and long service life.\u003c\/p\u003e","brand":"Lennox","offers":[{"title":"Default Title","offer_id":63081134195059,"sku":"LNX-83L71","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-83L71.jpg?v=1783763637","url":"https:\/\/nationalhvacparts.com\/products\/oem-lennox-spark-electrode-ignitor-assembly-83l71","provider":"National HVAC Parts","version":"1.0","type":"link"}
