Carrier 48GX Air Pressure Switch
The job of an air pressure type switch is to sense if the primary blower is running properly. This pressure switch is one of the key mechanisms designed to keep you from harm. The majority of pressure switches have a manual reset feature, which means it would need to be reset in order for the HVAC system to continue running.
Common Indications of a Failed Pressure Switch
- Inaccurate volt range running through the pressure switch.
- The furnace will not operate.
- Your system doesn't achieve the desired indoor temperature.
