International Comfort Products PGC060K100F Air Pressure Switch
The actual job of the pressure switch is to sense whether the primary blower is running. This is one of many other hardware devices made to keep you from harm. A good number of pressure switches today can have a manual reset, which, of course, means that it would have to be reset by hand before the HVAC system will continue.
Signals that the Air Pressure Switch has Failed
- The set indoor temperature is almost never achieved.
- Bad electrical voltage running through the switch.
- The furnace or AC can not run correctly.
