Carrier FV4CNF003 Air Pressure Switch
The job of the pressure switch is to see if the blower is blowing air. An air pressure switch is one of the vitally important safety devices designed to keep you safe. A good number of pressure switches today may have a manual reset, which means it will have to be manually reset before the HVAC system will continue.
Warning Signs that the Pressure Switch is Starting to Go Bad
- HVAC system will not run.
- The right temperature indoors is hardly ever fully attained.
- Bad electrical voltage running through the switch.
