Limit switches are crucial due to the fact that if the air inside the furnace is too cool the you will lose all the heat as the air flows through the ducts. A normal limit switch is a switch in the heat exchanger that senses, or governs, when the heated air is warmed to a point so that it may be pushed through the ducts and out the vents.
