The genuine OEM Lennox 80K09 ignitor electrode is responsible for lighting the burners at the start of every heating cycle. When the control board calls for heat, the ignitor heats up (or sparks) to ignite the gas as the valve opens. Because it endures intense thermal cycling with each run, the ignitor is one of the most common wear items in any Lennox furnace.
Common failure symptoms include:
- Furnace clicks and tries to start but never lights
- No visible glow or spark at the ignitor
- Cracked, blistered, or visibly broken igniter element
- Repeated ignition lockout after several failed attempts
Ignitors are fragile and degrade gradually, so a no-heat call during cold weather is often traced directly to a failed 80K09. Installing the correct OEM part restores dependable first-attempt ignition.
Why OEM matters: Lennox specifies precise ignitor resistance, mounting geometry, and positioning relative to the burner. A mismatched aftermarket ignitor can sit at the wrong distance from the flame, ignite late, or crack prematurely. The OEM 80K09 guarantees the correct fit, electrical rating, and flame alignment for consistent, safe lighting.
