It moves heat from the combustion process into the circulating air stream while safely containing flue gases, and its stainless steel construction resists the corrosion and thermal fatigue that shorten the life of lesser materials.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCommon failure symptoms:\u003c\/strong\u003e Watch for cracks, rust, or scaling on the exchanger surface, soot buildup, flames that flicker or roll out of the burner box, unusual odors during operation, or a triggered carbon monoxide detector. Reduced heating output, frequent limit-switch shutdowns, and metallic popping sounds on ignition are also signs the exchanger has failed and needs replacement.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy OEM matters:\u003c\/strong\u003e Because a heat exchanger separates toxic combustion gases from the air your family breathes, precise fit and metallurgy are critical. The genuine Lennox \u003cstrong\u003e94M05\u003c\/strong\u003e is manufactured to the original stainless steel spec, weld quality, and dimensional tolerances your furnace requires for a safe, sealed installation. Choosing OEM preserves rated efficiency, proper airflow, and any remaining equipment warranty.\u003c\/p\u003e","brand":"Lennox","offers":[{"title":"Default Title","offer_id":63081076916595,"sku":"LNX-94M05","price":399.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-lennox-stainless-steel-heat-exchanger-94m05","provider":"National HVAC Parts","version":"1.0","type":"link"}
