A normal limit switch is a type of sensor switch in the air handler that senses, or governs, if and when the air is warm enough for the blower to be activated. The main reason limit switches are made is because if the air never warms up the you will lose heat in the ducts and the vents will just blow cool air.
Main clues limit switch needs replacing ASAP
