OEM Lennox Stainless Steel Inshot Burner — 75W41

The genuine OEM Lennox 75W41 stainless steel inshot burner (Lennox reference R39271B002) delivers the fuel-air mixture into the heat exchanger tube of your Lennox gas furnace and shapes the flame for clean, complete combustion. The stainless steel construction resists heat, corrosion, and scaling, providing consistent ignition and long service life across countless heating cycles.

When an inshot burner becomes clogged, corroded, or misaligned, you may experience delayed or rough ignition, flame rollout, a yellow or lazy flame instead of a crisp blue one, popping and rumbling on startup, or repeated ignition-failure lockouts. Debris and rust on the burner ports disrupt the flame and can compromise both efficiency and safety, making replacement worthwhile at the first sign of trouble.

Selecting the OEM Lennox 75W41 burner ensures the exact port pattern, orifice alignment, and stainless material Lennox designed for this furnace, so the flame lands correctly in the heat exchanger and the gas valve and ignition controls operate as intended. Generic burners often flame differently, leading to poor efficiency, sooting, or nuisance faults. This factory part restores precise, safe combustion and protects your Lennox equipment.
