International Comfort Products HHP224AKA1 Limit Switch
A normal limit switch is a switch in the heat exchanger that determines if and when the air is actually warm enough so that it may be pushed through the ducts and out the vents. One big reason why limit switches are designed that way is because if the air is not warm enough the you will lose all the heat as the air flows through the ducts.
