International Comfort Products NTV6100KJA1 Limit Switch
A limit switch was crafted due to the fact that if the air never warms up inside the exchanger the you will lose heat in the ducts and the vents will just blow cool air. A normal limit switch contains a sensor in the heat exchanger that makes the determination when the heated air is warm enough that it can be circulated throughout the house.
What warnings are present when my main limit switch is in need of replacing?
- The heating and AC system will not initiate or continue to run longer than 30 seconds
- The system starts to act weird from time to time
