Carrier 48KLA Limit Switch
The limit switch is a type of sensor switch located in the furnace that can determine when the air is warm enough for the blower to be activated. One big reason why limit switches are designed that way is due to the fact that if the air never warms up inside the exchanger then you will never get hot air through the ducts.
