    What to do if my VAT PLUTO has high discharge pressure?
    • J
      James ToddAug 25, 2025
      If your VAT Refrigerator is experiencing high discharge pressure (higher than 240 psi), ensure that the condenser fan is functioning and that the airflow is sufficient. Also, verify that the condenser coil is free from dirt and debris. Finally, check the high-pressure switch and its continuity to the controller.

    Why is the evaporator iced up in my VAT PLUTO Refrigerator?
    • D
      David DuranAug 25, 2025
      If your VAT Refrigerator's evaporator is iced up, it may be due to a needed defrost, a plugged drain, or insufficient airflow. Inspect the evaporator condensation drain to ensure it is not blocked by dirt or a kinked hose.
