Carrier FY4ANF048000 Air Pressure Switch
The main job of the air pressure switch is to see if the primary blower is on and running. Various air pressure switches may have a reset feature that is manual, which means it will have to be manually reset before the HVAC system will continue. This is part of a small, but important collection of mechanisms designed to stop injuries or explosions.
What Signs are Present when your Pressure Switch is Starting to Fail
- The proper temperature indoors is almost never attained.
- The furnace or AC is unable to function.
- Bad volt range being used by the switch.
