Product Details

The Lennox 79J22 is a genuine OEM flame sensor designed for Lennox gas furnaces. This critical safety component detects the presence of flame during the heating cycle, allowing the furnace to operate safely and efficiently.

Key Features:

  • Genuine Lennox OEM replacement part
  • Ensures proper flame detection and safe furnace operation
  • Prevents gas valve from opening without proper ignition
  • Direct replacement for failed or corroded flame sensors
  • Easy installation with standard mounting bracket

The flame sensor works by detecting the electrical current generated when gas combustion occurs. Over time, flame sensors can become coated with carbon buildup or corrosion, preventing proper flame detection and causing the furnace to shut down prematurely. Regular replacement of this component helps maintain safe and reliable furnace operation.
