Review CARRIER Lennox Furnace Flame Sensor

The Lennox PSE-L73 Carbon Monoxide and Flame Sensor is an essential safety component for your Lennox furnace model, ensuring the reliable and efficient operation of your heating system. This sensor is designed to detect the presence of both flames and carbon monoxide gas, providing an added layer of protection for your home.

The flame sensor is a critical component in the ignition sequence of your furnace. It monitors the presence of a flame in the combustion chamber during the ignition process. If a flame is not detected, the furnace will not continue to operate, preventing potential safety issues. This sensor is made of a robust and durable ceramic material, designed to withstand the high temperatures and harsh conditions of your furnace.

In addition to detecting flames, the PSE-L73 sensor also includes a carbon monoxide (CO) detection feature. Carbon monoxide is an odorless, colorless, and potentially deadly gas that can leak from faulty furnaces or other appliances. The sensor uses an electrochemical cell to continuously monitor CO levels in your home. If CO levels exceed safe limits, the sensor will trigger an alarm, alerting you to the potential danger.

The Lennox PSE-L73 Carbon Monoxide and Flame Sensor is designed for easy installation, making it a convenient addition to your existing Lennox furnace system. This sensor is compatible with select Lennox furnace models, and installation typically involves connecting the sensor wires to the corresponding terminals on your furnace control board.

The sensor housing is made of a high-quality, corrosion-resistant material, ensuring long-lasting performance and durability. The sensor is designed to be low maintenance, with a long lifespan and minimal required upkeep. However, it is essential to follow the manufacturer's recommended maintenance schedule to ensure optimal performance and safety.

In summary, the Lennox PSE-L73 Carbon Monoxide and Flame Sensor is an essential safety component for your Lennox furnace system. It provides reliable flame detection and carbon monoxide protection, ensuring the efficient and safe operation of your heating system. The sensor is easy to install and made of durable materials, making it a valuable investment for your home comfort and safety.
