International Comfort Products TCA448AKA1 Limit Switch
A normal limit switch contains a sensor in the heat exchanger that decides when the air is warmed to a point so that it may be pushed through the ducts and out the vents. Limit switches are built because if the warmed air is too cool then the house will never get warm enough.
