International Comfort Products GNL100N16C3 Air Pressure Switch
The job of the air pressure switch is to sense if the blower fan is circulating the air as it should. This pressure switch is one of the critical mechanisms designed to stop injuries or explosions. A lot of switches are constructed with a manual reset, which means it would need to be reset or the whole HVAC system will not continue operation.
Symptoms that your Pressure Switch is Beginning to Go Bad
- Furnace will not operate.
- The proper temperature is almost never fully achieved.
- Incorrect volt being read.
