{"product_id":"oem-lennox-heat-exchanger-assembly-47m52","title":"OEM Lennox Heat Exchanger Assembly — 47M52","description":"\u003cp\u003eThe genuine OEM Lennox \u003cstrong\u003e47M52\u003c\/strong\u003e heat exchanger assembly is the core combustion component of your Lennox gas furnace. It transfers heat from the burning fuel to the air circulating through your home while keeping combustion gases safely separated from the airstream. This factory assembly is engineered to the exact tolerances, alloy, and dimensions Lennox specifies, ensuring proper airflow, rated efficiency, and safe operation.\u003c\/p\u003e\u003cp\u003eA failing heat exchanger often reveals itself through cracks, rust or scaling, a flickering or rolling burner flame, soot buildup, or a persistent smell of combustion. In many cases a cracked heat exchanger will trip the furnace's safety limits and cause short-cycling. Because a compromised exchanger can allow carbon monoxide to leak into living spaces, prompt replacement is a critical safety matter — not just a comfort one.\u003c\/p\u003e\u003cp\u003eChoosing OEM matters: only the genuine Lennox \u003cstrong\u003e47M52\u003c\/strong\u003e is built to withstand the thermal stress cycles of your specific furnace model without warping or premature metal fatigue. Aftermarket substitutes can fit poorly, disrupt heat transfer, void your warranty, and shorten furnace life. Install the correct factory part and restore your Lennox system to safe, efficient performance.\u003c\/p\u003e","brand":"Lennox","offers":[{"title":"Default Title","offer_id":63081072394611,"sku":"LNX-47M52","price":399.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-lennox-heat-exchanger-assembly-47m52","provider":"National HVAC Parts","version":"1.0","type":"link"}
