International Comfort Products NDC7075BFA2 Limit Switch
The limit switch has a sensor in the heat exchanger that decides when the heated air is warm enough to activate the main blower. One big reason why limit switches are designed that way is because if the air never warms up then you will never get hot air through the ducts.
Symptoms of a deteriorating main limit switch
- The system starts to become unpredictable occasionally
- The heating and cooling system is unable to start or run well like it ought to
