Carrier FB4CNF030 Air Pressure Switch
The main function of an air pressure type switch is to sense if the primary air circulator is circulating the air as it should. This pressure switch is one of the vitally important safety device to keep your family safe and sound. A good number of pressure switches today are designed with a reset that is manual instead of automatic, which makes you reset it by hand before the entire HVAC system will continue operating again.
Signs that your System Pressure Switch is Failing
- Your heating and cooling system will not run.
- Inaccurate voltage range being read from the pressure switch.
- The right temp is almost never reached.
