Mitsubishi MSZ-FA25VA Air Pressure Switch
The primary function of this type of switch is to sense if the blower is doing what it is supposed to do. This switch is part of the safety system that is in place to keep you safe from any injuries. The majority of pressure switches may have a manual reset, which makes you reset it by hand before you can continue using the system.
Signs that the System Pressure Switch is Failing
- The blower can not run.
- Bad electrical voltage reading from the switch.
- Your system doesn't get to the correct temp according to the settings on the thermostat.
