Mitsubishi MSZ-FD09NA Air Pressure Switch
The main job of the switch is to determine whether the primary blower is doing what it is supposed to do. A good number of pressure switches today can have a manual reset, which makes you reset it by hand before the system will continue its normal operation. An air pressure switch is just one of many device to keep you safe.
