Carrier 38ARS008 Air Pressure Switch
The actual job of this type of switch is to figure out if the blower is running properly. Various air pressure switches are programmed with a manual reset, which forces the system to be reset physically before the entire HVAC system will continue operating again. This pressure switch is one of many other safety creations designed to stop injuries or explosions.
Warning Signs that the Pressure Switch is About to go Bad
- The expected temperature in the house seldom reached.
- Bad voltage reading.
- The furnace is unable to operate.
