Carrier 48XZ048130300 Limit Switch
The limit switch is a type of sensor switch in the heat exchanger that can determine when the heated air is warm enough so that it may be pushed through the ducts and out the vents. The reason limit switches exist is because if the air is too cool inside the furnace to begin with, then you will never get hot air through the ducts.
