A normal limit switch has a sensor in the air handler that makes the determination if and when the air is warmed to a point for the blower to be activated. A limit switch was crafted because if the air is too cool inside the furnace to begin with, the you will lose all the heat as the air flows through the ducts.
Major clues main limit switch is going out
