Carrier 50JS030300 Air Pressure Switch
The function of the switch is to figure out if the blower fan is blowing air. This pressure switch is one of the vitally important safety devices that are created to keep you from harm. A lot of switches are programmed with a manual reset, which, of course, means that it would have to be reset by hand before the system will continue its normal operation.
Signs to Look Out for when the Switch has Failed
- Wrong voltage range being read.
- HVAC system can not run correctly.
- Your system doesn't achieve the desired temperature as set by the thermostat.

If you are unsure about the installation of the air pressure switch by yourself then it is probably best to find a professional in your area to do the work for you.
