Carrier 58STA090 Air Pressure Switch
The job of an air pressure type switch is to sense if the air blower is actually running. This is one of the vitally important safety mechanisms designed to keep you from harm. The majority of pressure switches are issued with a manual reset feature, which, of course, means that it would have to be reset by hand or the entire system will not run.
Symptoms that your Air Pressure Switch will go Bad
- HVAC system will not function.
- Incorrect electrical voltage running through the switch.
- The right temperature indoors is hardly ever attained.
