A475 Error Code: Flame Sensor Issue

  • The Lennox A475 error code signifies a problem with the flame sensor in your furnace. The flame sensor plays a crucial role in ensuring safe and efficient combustion within the furnace. When it malfunctions, it can lead to heating issues and potential safety concerns.

Why Does the Flame Sensor Matter?

  • The flame sensor is responsible for detecting the presence of a flame within the furnace. If it fails to sense the flame correctly, the furnace may not ignite or stay lit, leading to heating problems.

Common Causes of Flame Sensor Issues:

    1. Dirt and Soot Buildup: Over time, the flame sensor can accumulate dirt, soot, or debris, hindering its ability to detect the flame accurately.
    1. Sensor Misalignment: In some cases, the flame sensor may become misaligned, preventing it from properly sensing the flame.
    1. Sensor Wear and Tear: Like any component, the flame sensor can experience wear and tear, leading to reduced functionality.
