Mitsubishi MSZ-A24NA Air Pressure Switch
The function of the pressure switch is to see if the blower fan is doing what it is supposed to do. A good number of pressure switches today can have a manual reset, which, of course, means that it would have to be reset by hand in order for the HVAC system to continue running. This switch is a very critical piece of all the safety features in today's HVAC systems in place to keep you safe from potential hazards in the house.
What Signs are Present when your Air Pressure Switch is on its Last Leg
- The proper temperature in the house is almost never fully achieved.
- Incorrect volt range running through the switch.
- HVAC system is unable to function.
