Frequently Asked Questions (27)

  • Why is my Fujitsu AUXG07KVLA air conditioner leaking water?

    Water leakage can occur due to several reasons:

    • Erroneous installation: This can happen if the main unit is not installed in a stable condition, or if it was broken or deformed during transportation or maintenance.
    • Drain hose failure: Check if the drain hose connection is loose, if there is a trap in the drain hose, or if the drain hose is clogged.
    • Clogged filter: If water is spitting out, the filter might be clogged.
    • Fan not rotating: Ensure the fan is rotating properly.

    For more information, see page 286 of the manual.

  • Why is my Fujitsu AUXG07KVLA air conditioner not blowing cold air?

    If your air conditioner is not blowing cold air, consider the following:

    • Indoor unit issues: Check if the indoor unit fan is running in HIGH mode, if the air filter is dirty, if the heat exchanger is clogged, or if the energy save function is operated.
    • Outdoor unit issues: Ensure the outdoor unit is operating, there are no objects obstructing the air flow route, the heat exchanger is not clogged, and the valve is open.
    • Installation and environment: Verify if the capacity of the indoor unit fits the room size, and check for open windows or direct sunlight. Also, inspect the connection pipe (length and diameter) and any loose or removed communication lines.
    • Refrigeration cycle issues: This could be due to a clogged strainer, refrigerant leakage, or a defective electronic expansion valve (EEV) or capillary tube. Issues with the compressor can also prevent cooling.

  • Why is my Fujitsu AUXG07KVLA air conditioner not responding to the remote?

    If your air conditioner is not responding to the remote control, consider the following:

    • Custom Code Mismatch: The remote controller's custom code must match the indoor unit's setting. If you don't know the correct code, you may need to try each of the custom codes (A, b, c, d) until the remote operates the air conditioner.
    • Wired Remote Connection Issues: For wired remote controllers, check for incorrect wiring between the indoor unit and remote controller, or if there is an open cable connection. Also, verify the voltage at CN14 (terminal 1-3) of the main PCB or communication PCB.
    • Function Setting Mode: The indoor unit will reject any operation commands from the remote controller when it is in the address setting mode.
