International Comfort Products NTVM125KNA1 Limit Switch
Limit switches are built due to the fact that if the air inside the furnace is too cool the you will lose heat in the ducts and the vents will just blow cool air. A normal limit switch has a sensor in the heating area that senses, or governs, when the heated air is actually warm enough for the main blower to kick in and circulate the air.
Major indications of a poorly working limit type switch
- The system begins to act differently occasionally
- Your International Comfort Products system is unable to start or will not stay running like it ought to
