Carrier ZW Air Pressure Switch
The primary function of an air pressure type switch is to determine whether or not the primary blower is running properly. Various air pressure switches have a manual reset feature, which means you have to physically reset it or the entire system will not run. An air pressure switch is just one of many mechanisms designed to stop injuries or explosions.
Signs that your Air Pressure Switch will Soon Fail
- The furnace or AC refuses to run correctly.
- Incorrect voltage range running through the switch.
- HVAC system does not get to the correct temp.
