Haier CPN12XH9 Air Pressure Switch
The actual job of the pressure switch is to sense if the main blower is on and running. This switch is one of the key hardware devices made to keep you from harm. The majority of pressure switches are programmed with a manual reset, which means you have to physically reset it in order for the system to begin normal operations again.
Warning Signs that the System Pressure Switch will Fail Soon
