{"product_id":"oem-lennox-flame-sensor-lead-88a12","title":"OEM Lennox Flame Sensor Lead — 88A12","description":"\u003cp\u003eThe genuine OEM Lennox \u003cstrong\u003e88A12\u003c\/strong\u003e flame sensor lead is the high-temperature wire that carries the flame-rectification signal from the sensor rod back to your Lennox furnace control board. This tiny current tells the board that a flame is present, allowing the gas valve to stay open safely during a heating cycle.\u003c\/p\u003e\u003cp\u003eA damaged or degraded \u003cstrong\u003e88A12\u003c\/strong\u003e lead can cause intermittent flame loss, furnace lockouts after a few seconds of burner operation, short-cycling, and repeated no-heat calls. Because the signal is measured in microamps, even a frayed conductor, cracked insulation, or loose terminal can interrupt detection and shut the furnace down as a safety measure.\u003c\/p\u003e\u003cp\u003eOEM matters here because the \u003cstrong\u003e88A12\u003c\/strong\u003e uses the correct high-temperature insulation, gauge, and terminal fit for Lennox equipment. Generic wire can melt near the burner, create a poor connection, or introduce resistance that weakens the flame signal. This factory replacement lead ensures clean, reliable flame detection and safe furnace operation.\u003c\/p\u003e","brand":"Lennox","offers":[{"title":"Default Title","offer_id":63081092940147,"sku":"LNX-88A12","price":19.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0984\/1190\/5395\/files\/nhvac-flame-sensor-straight-LNX-88A12.jpg?v=1783760999","url":"https:\/\/nationalhvacparts.com\/products\/oem-lennox-flame-sensor-lead-88a12","provider":"National HVAC Parts","version":"1.0","type":"link"}
