Mitsubishi PLA-ABA Air Pressure Switch
The job of the switch is to sense whether the air blower is circulating the air as it should. Some different switches are programmed with a manual reset, which makes you reset it by hand or the whole HVAC system will not continue operation. An air pressure switch is one of many other aspects of the whole safety system that is intended to keep you from harm.

- Bad volt being read from the pressure switch.
- The furnace or AC is unable to operate.
