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. A normal limit switch is a type of sensor switch in the heat exchanger that can determine if and when the air is actually warm enough for the air to begin normal home circulation.
Symptoms limit switch has to be replaced
