Payne PH3ZNA036000AA Air Pressure Switch
The main job of an air pressure type switch is to determine whether or not the primary blower is blowing air. This is one of many other devices that are created to keep your family safe and sound. Various air pressure switches are programmed with a manual reset, which makes you reset it by hand in order for the system to begin normal operations again.
What to Look for when the Switch is Going Bad
