The Lennox 14C41 (factory number 612997-12) is a genuine OEM noise reduction burner assembly built for Lennox gas furnaces. Engineered to produce a stable, well-shaped flame while suppressing the combustion roar of conventional burners, this assembly keeps your furnace operating quietly and efficiently. It mounts precisely within the burner box and aligns with the gas manifold and igniter to ensure clean, consistent light-off on every heating cycle.
Common failure symptoms: When this burner assembly wears or corrodes, you may hear loud roaring or rumbling at ignition, notice delayed or rough light-off, uneven or yellow-tipped flames, soot buildup, or short-cycling caused by poor flame sensing. A sudden increase in combustion noise is a classic sign the noise reduction burner needs replacement.
Why OEM matters: The Lennox 14C41 is manufactured to exact factory specifications, so flame geometry, gas metering, and noise-dampening baffles match your furnace's original engineering. Aftermarket burners can upset the air-fuel mixture, reintroduce noise, and void warranty coverage. Selecting the genuine 14C41 guarantees proper fit, rated efficiency, and safe, quiet combustion for your Lennox system.
