Carrier 58DLX09010020 Air Pressure Switch
The function of an air pressure type switch is to figure out if the primary blower is running. This is one of the vitally important safety mechanisms designed to stop injuries or explosions. A good number of pressure switches today are programmed with a manual reset, which, of course, means that it would have to be reset by hand before the HVAC system will continue.
Clues that your System Pressure Switch is Starting to Go Bad
- The furnace or AC can not run correctly.
- The expected temperature in the house seldom fully achieved.
- Inaccurate volt range being read from the pressure switch.
