International Comfort Products PGS048L120F Air Pressure Switch
The job of an air pressure type switch is to determine whether or not the blower fan is running properly. A lot of switches are equipped with a manual reset feature, which means it would need to be reset in order for the system to begin normal operations again. This is one of many other facets of the HVAC safety checks that are dedicated to keep your family safe and sound.
What to Look for when your Air Pressure Switch is Starting to Fail
- The furnace or AC can not operate.
- Inaccurate voltage range reading from the switch.
- The right indoor temperature is almost never fully achieved.
