International Comfort Products NHP042AKA1 Air Pressure Switch
The main function of an air pressure type switch is to see if the blower fan is circulating the air as it should. This switch is part of a small, but important collection of devices designed to keep you safe. Some pressure switches may have a reset feature that is manual, from which it would have to be reset manually or else the system will cease to function.
Precursors that the Switch is Starting to Go Bad
- The right temperature is almost never achieved.
- Inaccurate volt range running through the pressure switch.
- The furnace is unable to ignite.
