Carrier 38CQ Limit Switch
The main reason limit switches are made is because if the air is too cool inside the furnace to begin with, the you will lose heat in the ducts and the vents will just blow cool air. The limit switch is a switch located in the furnace that determines when the air is actually warm enough for the blower to be activated.
