Carrier 48XZ036090300 Air Pressure Switch
The main job of the pressure switch is to determine whether or not the primary blower is blowing air. Some particular air pressure switches are constructed with a manual reset, which means you have to physically reset it in order for the system to begin normal operations again. This pressure switch is one of the vitally important safety aspects of the whole safety system that is intended to keep you safe.
