International Comfort Products PGAA24C1K1 Limit Switch
The main reason limit switches are made is due to the fact that if the air inside the furnace is too cool the you will lose all the heat as the air flows through the ducts. A normal limit switch has a sensor located in the furnace that can determine when the heated air is warmed to a point for the air to begin normal home circulation.
Symptoms limit switch should need replacing
- The heating and cooling system will not begin or run well like it should
- The International Comfort Products system is beginning to shut down unexpectedly often
