Samsung AVMHC105EA0 Limit Switch
A normal limit switch has a sensor in the air handler that determines if and when the air is warmed to a point for the main blower to kick in and circulate the air. A limit switch was crafted due to the fact that if the air inside the furnace is too cool the you will lose all the heat as the air flows through the ducts.
