Carrier 58STA13510016 Air Pressure Switch
The function of this type of switch is to determine whether the blower fan is doing what it is supposed to do. This switch is one of the key safety creations designed to keep you from harm. A good number of pressure switches today are programmed with a manual reset, by which you must manually reset it or the entire system will not run.
Indications of a Declining Pressure Switch
- The furnace refuses ignite.
- Your system doesn't get to the correct temperature when set by the thermostat.
- Inaccurate volt range being used by the switch.
