The genuine OEM Lennox 14D60 heat exchanger assembly — also cross-referenced as 612998-11 and 610280-17 — is the primary heat-transfer and combustion-containment component in your Lennox gas furnace. It moves heat from the burners into your home's air supply while sealing off carbon monoxide and other combustion gases from the airstream. Manufactured to factory tolerances, it preserves proper burner alignment and rated furnace efficiency.

Common failure symptoms: Cracks, rust, or holes in the exchanger, a burner flame that flutters or rolls out when the blower engages, soot deposits, odd odors, or a carbon monoxide detector triggering during operation. Because a compromised heat exchanger can leak combustion gases into your living space, replacement should not be postponed.

Why OEM matters: The exact metallurgy and geometry of the 14D60 are what keep combustion safely separated and heat transfer efficient. Verify the cross-reference numbers 612998-11 and 610280-17 against your unit for a confident match. Genuine OEM parts protect your warranty, your equipment, and your family. In stock and ready to ship same day.
