International Comfort Products C8DNL100F14A1 Limit Switch
The limit switch is a type of sensor switch located in the furnace that decides if and when the air is warm enough to activate the main blower. The reason limit switches exist is because if the air is not warm enough then you will never get hot air through the ducts.
Major signs to watch for in a bad limit type switch
- The whole system is beginning to stop suddenly more than once
- Your International Comfort Products system refuses to start or continue to run for any significant length if time
