    • M
      Mr. Christopher AndersenAug 2, 2025
      If your Hitachi Refrigerator is not getting cold enough, consider these solutions: * Ensure the refrigerator isn't exposed to sunlight or heat sources. * Select a colder setting by touching the “Refrigerator” button to normal or coldest. * Make sure there's enough space between food items for proper air circulation. * Ensure the refrigerator door is closed firmly. * Allow food to cool before placing it in the refrigerator. * Avoid opening and closing the door too frequently.

    Why does the control panel display keep changing on my Hitachi R-WB640VRU0?
    • K
      Katherine MorganAug 6, 2025
      If the control panel display of your Hitachi Refrigerator keeps changing, it probably means the refrigerator is running in store-display mode. To turn it off, power off the refrigerator and then power it on again. After that, the refrigerator should return to normal mode.

    • D
      Dr. Sean Juarez Jr.Aug 14, 2025

      The operation sound of your Hitachi Refrigerator may last long because the compressor operates in low-speed to conserve energy.

    Why does the operation sound sometimes become louder on my Hitachi R-WB640VRU0?
    • K
      Kenneth BakerAug 23, 2025
      The operation sound of your Hitachi Refrigerator sometimes becomes louder because the system changes the operating power of the refrigerator according to the temperature change.

    Why are there dews or water around the door or inside the Vacuum Compartment of my Hitachi Refrigerator?
    • S
      Stephanie GriffinAug 27, 2025
      If you notice dews or water around the door or inside the Vacuum Compartment of your Hitachi Refrigerator, a 'Whoosh...' sound during opening is normal. Check for items stored in the Packing or the inmost side of the Vacuum Compartment. If the sound or shaking occurs often, there may be something at the door, or the packing may be dirty. Moisture in food and air can also form dew inside the Vacuum Compartment as it is completely closed.
