Friedrich VEA24K Limit Switch
The limit switch is a type of sensor switch located in the furnace that makes the determination when the heated air is actually warm enough for the main blower to kick in and circulate the air. A limit switch was crafted 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.
