Lennox 14ACX-048 Limit Switch
A limit switch was crafted because if the air is not warm enough the you will lose heat in the ducts and the vents will just blow cool air. The limit switch is a type of sensor switch in the air handler that senses, or governs, if and when the air is warmed to a point for the blower to be activated.
