Carrier 38EZA042 Air Pressure Switch
The actual job of the pressure switch is to determine whether or not the main blower is blowing air. An air pressure switch is one of the vitally important safety mechanisms designed to keep you from harm. Some particular air pressure switches are programmed with a manual reset, which means it will have to be manually reset in order for the system to begin normal operations again.
Warning Signs that the Pressure Switch is Beginning to Go
- The proper temp is never achieved.
- Incorrect voltage range running through the switch.
- HVAC system refuses to operate properly.
