It continuously reads safety inputs and thermostat demand to deliver correct, efficient, and protected operation.\u003c\/p\u003e\u003cp\u003eWhen a control board fails, symptoms range widely: no response to a thermostat call, blower or inducer that won't start or won't shut off, intermittent ignition, error codes flashed by the diagnostic LED, or a furnace that resets randomly. Burnt relays, scorched traces, blown fuses, or failed sensing circuits on the board are common indicators that replacement is needed.\u003c\/p\u003e\u003cp\u003eAn OEM Lennox \u003cstrong\u003e86G16\u003c\/strong\u003e ships with the exact firmware, relay ratings, timing parameters, and connector layout your furnace was designed around. Universal or aftermarket boards may lack model-specific logic and diagnostics, leading to improper sequencing, reduced efficiency, or voided warranty coverage. Install the factory-matched board to restore full, reliable control of your Lennox system.\u003c\/p\u003e","brand":"Lennox","offers":[{"title":"Default Title","offer_id":63081144516979,"sku":"LNX-86G16","price":129.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0984\/1190\/5395\/files\/nhvac-control-board-furnace-LNX-86G16.jpg?v=1783759981","url":"https:\/\/nationalhvacparts.com\/products\/oem-lennox-control-board-86g16","provider":"National HVAC Parts","version":"1.0","type":"link"}
