International Comfort Products PGAA Limit Switch
The limit switch has a sensor located in the furnace that makes the determination when the heated air is warmed to a point for the blower to be activated. A limit switch was crafted due to the fact that if the air never warms up inside the exchanger the you will lose heat in the ducts and the vents will just blow cool air.
Major indications critical limit switch should need replacing
- The heating and cooling system refuses to kick in or will not stay running longer than 30 seconds
- The system begins to become unpredictable often
