International Comfort Products PA5524AKA1 Air Pressure Switch
The primary function of this type of switch is to sense if the primary blower is on and running. An air pressure switch is one of the vitally important safety hardware devices made to keep you safe. The majority of pressure switches are programmed with a manual reset, which, of course, means that it would have to be reset by hand or the entire system will not run.
Signs that the System Pressure Switch is Starting to Go Bad
- Inaccurate volt range reading.
- The furnace can not operate.
- The correct temp is hardly ever achieved.
