International Comfort Products HAC018AKA1 Limit Switch

A normal limit switch has a sensor located in the furnace that makes the determination if and when the air is warm enough for the air to begin normal home circulation. Limit switches exist due to the fact that if the air never warms up inside the exchanger then you will never get hot air through the ducts.
