Lennox 28M97 Flame Sensor this 1-inch nominal copper elbowThe Lennox 28M97 Flame Sensor is a vital OEM replacement part engineered for precise flame rectification in gas fired furnaces. This furnace flame sensor facilitates a safe ignition sequence by detecting the presence of a burner flame through ionization. If the control board loses the microamp signal, it immediately terminates the gas flow to prevent hazardous accumulation. This sensor is the factory identical component to 28M9701 and serves as a
