Carrier 25HPA336A0030010 Air Pressure Switch
The actual job of the switch is to determine whether the blower fan is running properly. This pressure switch is just one of the many indispensable devices that are created to stop injuries or explosions. A lot of switches are programmed with a manual reset, which, of course, means that it would have to be reset by hand in order for the HVAC system to continue running.
Symptoms that your Air Pressure Switch will go Bad
- Inaccurate electrical voltage reading from the switch.
- Your furnace refuses operate at all.
- The proper temperature in the house is rarely fully achieved.
