Carrier 50ZP-048 Air Pressure Switch
The main function of an air pressure type switch is to see if the blower fan is running. Some different switches are issued with a manual reset feature, which means you have to physically reset it in order for the HVAC system to continue running. This switch is one of the vitally important safety devices that are created to keep you from harm.
Signs that the System Pressure Switch will Fail Soon
- Furnace can't run.
- System does not actually get to the right temp according to the settings on the thermostat.
- Bad volt being read from the pressure switch.
