International Comfort Products NTG3100KFA1 Limit Switch
The limit switch has a sensor in the heat exchanger that decides when the heated air is actually warm enough that it can be circulated throughout the house. One big reason why limit switches are designed that way is because if the air is not warm enough the you will lose heat in the ducts and the vents will just blow cool air.
Clues to watch for to know limit switch will have to be replaced
- System will not start or run well even though max temp has not been reached
- The whole system is beginning to act weird more often than not
