International Comfort Products N8MPN125J20B1 Air Pressure Switch
The job of the pressure switch is to determine whether the air blower is circulating the air as it should. This is one of many other facets of the HVAC safety checks that are dedicated to keep you safe. Some particular air pressure switches may have a reset feature that is manual, which, of course, means that it would have to be reset by hand before the HVAC system will continue.
Signals that the Air Pressure Switch has Gone Bad
- Your heating and cooling system refuses to run.
- System does not achieve the desired temp.
- Wrong voltage reading.
