The limit switch has a sensor in the heating area that can determine when the heated air is warm enough that it can be circulated throughout the house. Limit switches are built because if the air is too cool inside the furnace to begin with, the you will lose heat in the ducts and the vents will just blow cool air.
Major symptoms of a bad critical limit switch
