International Comfort Products NDN6100GFA1 Air Pressure Switch
The job of the air pressure switch is to determine whether or not the blower fan is doing what it is supposed to do. An air pressure switch is one of many other hardware devices made to keep you safe. Some particular air pressure switches have a manual reset feature, which forces the system to be reset physically or the whole HVAC system will not continue operation.
Signs that the Switch is About to go Bad
- The furnace or AC will not run correctly.
- The desired indoor temperature is never achieved.
- Bad voltage running through the pressure switch.
