International Comfort Products N8MPN125J22B1 Air Pressure Switch
The function of the air pressure switch is to sense whether the blower fan is doing what it is supposed to do. A good number of pressure switches today may have a reset feature that is manual, which makes you reset it by hand before you can continue using the system. This is one of the key hardware devices made to keep you from harm.
Warning Signs that the Pressure Switch is Already Failing
- The blower fan refuses to run.
- The proper temperature indoors is rarely fully attained.
- Incorrect electrical voltage being used by the switch.
