Lennox 40L81 Flame Sensor Kit: Essential for Optimal Combustion Efficiency The Lennox 40L81 Flame Sensor Kit is a crucial component for ensuring the safe and efficient operation of your Lennox gas furnace. This kit consists of a flame sensor and mounting hardware, designed to detect the presence of a flame in the combustion chamber. Ensuring Ignition and Flame Stability: The flame sensor plays a vital role in detecting the presence of flame during the ignition process.

This signal keeps the gas valve open, allowing fuel to flow and maintain a steady flame throughout the heating cycle. Safety Feature: In case the flame is extinguished accidentally, the flame sensor detects the absence of flame and sends a signal to the control board. This triggers the gas valve to close, preventing any further flow of gas and ensuring safety.
