The limit switch has a sensor located in the furnace that makes the determination when the heated air is actually warm enough for the air to begin normal home circulation. Limit switches are crucial due to the fact that if the air never warms up inside the exchanger the you will lose heat in the ducts and the vents will just blow cool air.
Important clues of an unhealthy main limit switch
