The actual job of the pressure switch is to sense if the primary blower is running. Various air pressure switches may have a manual reset, which means it would need to be reset before the entire HVAC system will continue operating again. This switch is just one of many safety creations designed to keep your family safe and sound.
Clues that your System Pressure Switch is Beginning to Go Bad
