Lennox Furnace Flame Sensors

Every Lennox gas furnace contains a flame sensor as an important safety component to the unit. The flame sensor works by sending a message to the main furnace control board telling it to keep the main burner on and the gas valve open.

We offer a wide selection of Lennox furnace flame sensors as a direct replacement to various gas furnace models.
