Positioned precisely at the burner, the electrode arcs to ground to ignite the gas-air mixture at the start of each heating cycle. Correct gap and placement are essential for fast, dependable light-off.\u003c\/p\u003e\u003cp\u003eWhen a spark igniter degrades, you'll typically notice delayed ignition, repeated clicking without the burners catching, rough or noisy light-off, or complete ignition failure that locks out the furnace. Cracked ceramic insulators, an eroded electrode tip, or a shifted spark gap are the usual culprits.\u003c\/p\u003e\u003cp\u003eInstalling the OEM \u003cstrong\u003e43G62\u003c\/strong\u003e guarantees the exact electrode geometry, ceramic insulation, and spark gap your Lennox system was engineered for. Generic igniters often sit at the wrong angle or gap, causing weak sparks, delayed ignition that can produce a rollout, and premature failure. This factory-spec part restores crisp, reliable ignition and safe burner startup.\u003c\/p\u003e","brand":"Lennox","offers":[{"title":"Default Title","offer_id":63081088909683,"sku":"LNX-43G62","price":39.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0984\/1190\/5395\/files\/nhvac-igniter-silicon-carbide-LNX-43G62.jpg?v=1783763647","url":"https:\/\/nationalhvacparts.com\/products\/oem-lennox-spark-igniter-electrode-43g62","provider":"National HVAC Parts","version":"1.0","type":"link"}
