International Comfort Products PGS048K120F Air Pressure Switch
The main job of the air pressure switch is to determine whether the main blower is running properly. A good number of pressure switches today are issued with a manual reset feature, which, of course, means that it would have to be reset by hand before the system will continue its normal operation. The air pressure switch is a very critical piece of the collection of safety devices in place to keep you safe from injury or explosions.

- Wrong voltage being used by the switch.
- HVAC system does not reach desired temperature when set by the thermostat.
