International Comfort Products C9MPT075F14A2 Limit Switch
Limit switches were created because if the air never warms up the you will lose heat in the ducts and the vents will just blow cool air. A normal limit switch is a type of sensor switch in the heating area that determines when the heated air is warm enough for the blower to be activated.
