International Comfort Products NAC048GKA1 Air Pressure Switch
The main job of this type of switch is to sense if the blower is blowing air. Most air pressure switches are programmed with a manual reset, which, of course, means that it would have to be reset by hand before you can continue using the system. An air pressure switch is one of the vitally important safety devices designed to stop injuries or explosions.
Important Signs that the System Pressure Switch is Failing
- The set temperature seldom achieved.
- The furnace or AC will not run correctly.
- Incorrect voltage range running through the pressure switch.
