Mitsubishi PKA-A12HAL Air Pressure Switch
The reason for the existence of the switch is to sense whether the primary air circulator is doing what it is supposed to do. This is just one of many devices that are created to keep you safe. A good number of pressure switches today are issued with a manual reset feature, by which you must manually reset it before the entire HVAC system will continue operating again.
Symptoms that your System Pressure Switch is Already Failing
- The furnace will not run.
- The expected temperature is almost never achieved.
- Wrong volt range being read from the pressure switch.
