Review LENNOX Pse-137/1250 Flame Sensor/electrode 3.01 Inch Genuine Oem

The Lennox PSE-137/1250 Flame Sensor/Electrode is a crucial component in the safe and efficient operation of your Lennox gas furnace. Designed to detect the presence of a flame, this sensor plays a vital role in the furnace's ignition sequence and safety system.

This flame sensor, specifically model number PSE-137, is a 3.01-inch long ceramic rod with a diameter of approximately 0.25 inches. It is coated with a sensitive material that changes its electrical conductivity when exposed to a flame. When the sensor is correctly positioned in the burner's flame, it completes an electrical circuit, signaling the furnace to continue its operation.

The PSE-137 flame sensor is compatible with Lennox furnaces that have a 1250-watt igniter, making it an essential replacement part for those specific models. The sensor's robust design ensures its durability, but, like any other component, it may eventually wear out or fail due to natural wear and tear or other factors.

When the flame sensor fails, it might cause the furnace to malfunction, resulting in issues like the furnace not igniting or not producing enough heat. Replacing the faulty sensor with a new one, such as the Lennox PSE-137/1250, can typically resolve these issues, ensuring your furnace operates safely and efficiently.

The PSE-137/1250 Flame Sensor/Electrode from Lennox is an essential investment for the continued performance of your gas furnace. By ensuring a reliable flame detection system, you'll not only maintain the comfort of your home but also help prolong the life of your furnace and save on costly repairs.
