OEM Lennox Burner — 17J58 (T6-2110)

The genuine OEM Lennox 17J58 burner (Lennox reference T6-2110) mixes and delivers gas into the heat exchanger of your Lennox furnace, forming the shaped flame that generates the heat for your home. Manufactured to Lennox specifications, it provides consistent ignition and clean, efficient combustion cycle after cycle.

A burner that has become clogged, rusted, or distorted can cause noticeable performance problems: slow or rough ignition, a noisy startup with popping or rumbling, a yellow or flickering flame in place of a steady blue one, flame rollout, or repeated ignition-failure lockouts on the control board. These conditions reduce heating efficiency and can pose a safety concern, so prompt replacement is recommended.

Choosing the OEM Lennox 17J58 burner ensures the exact port pattern, dimensions, and orifice alignment your furnace was designed around, so the flame lands correctly in the heat exchanger and coordinates properly with the gas valve, igniter, and flame sensor. Generic replacements often differ in flame characteristics and can lead to sooting or nuisance faults. This factory part restores precise, safe, and efficient operation to your Lennox equipment.
