In This HVACR Training Video, We Diagnose a Gas Furnace Pressure Switch by Reading the Voltage Across the Switch and the Negative Water Column Pressure to see if the Pressure Switch is Open or Closed and Why the Error Code Exists. We use a Digital Multimeter and a Digital Dual Water Column Manometer for Troubleshooting. Supervision is needed by a licensed HVACR Tech while doing this as Experience and Apprenticeship garners Wisdom and Safety.
