Review LENNOX Flame Sensor Baso

The Lennox LE39F95 Flame Sensor, model number BASO Y75AH-1C, is an essential component of Lennox gas furnaces, ensuring safe and efficient operation. This flame sensor is designed to detect the presence of a flame in the furnace and send a signal to the furnace control board to continue the heating process.

The flame sensor is made of a ceramic material with a sensing tip coated with a special material that glows red when a flame is present. When a flame is detected, the electrical resistance of the sensor decreases, allowing electricity to flow through the sensor and activate the furnace's igniter. If no flame is detected, the sensor's resistance increases, preventing the igniter from activating and keeping the furnace from producing heat.

This Lennox flame sensor is designed to last for several years with proper maintenance. However, it may wear out or fail due to natural wear and tear or other factors, such as exposure to moisture or contaminants. When this happens, the furnace may not ignite, or it may produce erratic heating patterns.

To replace the flame sensor, simply remove the old sensor from the furnace and install the new BASO Y75AH-1C in its place. The sensor is easy to install, with clear instructions provided in the product packaging. It's essential to follow the installation instructions carefully to ensure the new sensor is properly seated and making good contact with the furnace's electrical terminals.

The Lennox LE39F95 Flame Sensor, BASO Y75AH-1C, is a high-quality replacement part designed to meet the demanding requirements of Lennox gas furnaces. It's manufactured to exacting specifications to ensure reliable performance and long-lasting operation. With this sensor, you can trust that your Lennox furnace will continue to provide safe and efficient heating for your home.
