The genuine OEM Lennox 13B52 primary ignitor is the hot surface igniter that lights the main burners in your Lennox gas furnace. When the thermostat calls for heat, the control board energizes the 13B52, which glows to a high temperature and ignites the gas as the valve opens. It is one of the most frequently replaced wear components in modern furnaces and is essential to reliable, safe startup.

Common failure symptoms: A failed 13B52 ignitor most often results in no heat, with the furnace attempting to start and then locking out. You may notice the igniter never glowing, a cracked or broken element, or the system running the inducer and blower but never lighting the burners. Igniters are brittle and commonly fail from age, thermal cycling, or handling damage.

Why OEM matters: The OEM 13B52 is engineered to match the exact resistance, glow temperature, and mounting position your Lennox ignition control requires. Generic igniters can draw the wrong current, position poorly over the burner, or fail prematurely — the factory part ensures proper fit, correct light-off timing, and long, dependable service life for your Lennox equipment.
