International Comfort Products NHP218GKA1 Air Pressure Switch
The main job of the air pressure switch is to determine whether the blower fan is actually running. Some different switches are designed with a reset that is manual instead of automatic, which means it will have to be manually reset or the whole HVAC system will not continue operation. This is just one of the many indispensable devices that are created to keep you safe.
Signs that the Air Pressure Switch will go Bad
- Inaccurate voltage range being read from the pressure switch.
- Furnace is unable to run.
- The correct temp seldom fully achieved.
