Lennox WING Limit Switch
A normal limit switch has a sensor in the heat exchanger that can determine if and when the air is warmed to a point for the main blower to kick in and circulate the air. A limit switch was crafted because if the air never warms up the you will lose all the heat as the air flows through the ducts.
Easy warnings of a dying critical limit switch
