International Comfort Products GPFM36L100F Limit Switch
A normal limit switch has a sensor in the heating area that determines when the heated air is actually warm enough to activate the main blower. The main reason limit switches are made is due to the fact that if the air never warms up inside the exchanger the you will lose all the heat as the air flows through the ducts.
Signals to watch for in a failing limit type switch
- The system is beginning to runs uneven time after time
- Your International Comfort Products system will not even start nor will it stay running as it should
