Carrier 48GX048090300 Air Pressure Switch
The main job of the air pressure switch is to determine whether the primary air circulator is doing what it is supposed to do. An air pressure switch is one of many other aspects of the whole safety system that is intended to keep you safe. A good number of pressure switches today are equipped with a manual reset feature, which means you have to physically reset it or the whole HVAC system will not continue operation.
