Carrier FB4CNF036 Limit Switch
A normal limit switch has a sensor in the heating area that determines when the air is warm enough for the air to begin normal home circulation. Limit switches are built 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.
