International Comfort Products NTC6100GFA Limit Switch
Limit switches were created due to the fact that if the air never warms up inside the exchanger then the house will never get warm enough. A normal limit switch contains a sensor located in the furnace that senses, or governs, when the heated air is actually warm enough for the main blower to kick in and circulate the air.
Easy warnings main limit switch needs replacing ASAP
