International Comfort Products NHP018AKA1 Air Pressure Switch
The primary function of the pressure switch is to sense whether the air blower is on and running. This pressure switch is one of many other devices designed to keep everyone in the house safe. Some particular air pressure switches may have a reset feature that is manual, which forces the system to be reset physically before the system will continue its normal operation.
Signs to Look Out for when the Switch is Failing
- System does not actually get to the right temp.
- Inaccurate voltage reading from the switch.
- The blower fan will not operate properly.
