International Comfort Products PGAA30C1K6 Air Pressure Switch
The job of the pressure switch is to see if the primary blower is running properly. This switch is one of the vitally important safety mechanisms designed to keep everyone in the house safe. Some pressure switches are programmed with a manual reset, by which you must manually reset it before you can continue using the system.
Signs that the Switch is Beginning to Go Bad
- The proper temperature is never achieved.
- HVAC system refuses to function properly.
- Bad volt running through the pressure switch.
