The genuine OEM Lennox 16M47 (factory reference LB-90359) is a burner cap used in Lennox furnace burner assemblies. The burner cap sits atop the burner and helps distribute gas and shape the flame across the burner ports, supporting even ignition and stable, uniform combustion. This small but important component contributes to clean burning and the reliable heat output your Lennox furnace was designed to deliver.
Common failure symptoms: A corroded, cracked, or misaligned burner cap can cause uneven or lifting flames, delayed ignition, combustion noise, soot, or inconsistent heating. Continuous exposure to combustion heat can degrade the cap over time, disrupting the flame pattern and burner performance.
Why OEM matters: Lennox produces the 16M47 to precise dimensions so it aligns correctly with the burner ports and maintains the intended flame geometry. Using the genuine OEM cap keeps combustion within factory specification, protecting both efficiency and safety. Non-OEM substitutes may fit poorly and disrupt the flame, leading to callbacks or unsafe operation. Restore proper burner performance with the authentic Lennox part.
