Carrier 50JX030300 Limit Switch

One big reason why limit switches are designed that way is due to the fact that if the air inside the furnace is too cool then you will never get hot air through the ducts. The limit switch has a sensor in the heat exchanger that determines when the heated air is warmed to a point that it can be circulated throughout the house.
