Frequently Asked Questions (21)

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

    If your Fujitsu AUXG07KVLA air conditioner is not blowing cold air, it could be due to several issues related to the indoor unit, outdoor unit, surrounding environment, connections, or refrigeration cycle. To troubleshoot, check the following:

    • Indoor unit:
      • Verify if the indoor unit fan is running in HIGH mode.
      • Check if the air filter is dirty.
      • Determine if the heat exchanger is clogged.
      • Check if the energy save function is operated.
    • Outdoor unit:
      • Confirm if the outdoor unit is operating.
      • Check for any objects obstructing the air flow route.
      • Verify if the heat exchanger is clogged.
      • Check if the valve is open.
    • Site condition:
      • Assess if the capacity of the indoor unit is appropriate for the room size.
      • Check for open windows or direct sunlight affecting the unit.
    • Installation condition:
      • Inspect the connection pipe for specified length and diameter.
      • Check for any loose or removed communication lines.
    • Refrigeration cycle:
      • Check if the strainer is clogged.
      • Measure gas pressure and check for leakage.
      • Check if the Electronic Expansion Valve (EEV) is open or if there is a capillary tube defect.
      • Inspect the compressor and inverter compressor.

    For more information, see page 226 of the manual.

  • Why is my Fujitsu AUXG07KVLA air conditioner leaking water?

    Water leaking from your air conditioner can be due to several reasons, including erroneous installation or drain hose failure. To diagnose the issue, check the following:

    • Main unit stability: Ensure the main unit is installed in a stable condition and was not broken or deformed during transportation or maintenance.
    • Drain hose: Check if the drain hose connection is loose, if there is a trap in the drain hose, or if the drain hose is clogged.
    • Fan rotation: Verify if the fan is rotating.
    • Filter: Check if the filter is clogged.
    • Gas pressure: Check gas pressure and correct it if there is a gas leak.

    For more information, see page 229 of the manual.

  • Why won't my Fujitsu AUXG07KVLA air conditioner turn on?

    If your Fujitsu AUXG07KVLA air conditioner won't turn on, it could be due to power supply issues, external factors, or defective electrical components. To diagnose the problem, check the following:

    • Installation Condition:
      • Verify if the circuit breaker is on or off.
      • Check for any loose or removed connection cables.
    • External Causes (Voltage Drop or Noise):
      • Determine if there's a large load electric apparatus in the same circuit causing instant drops.
      • Check for a defective contact or leak current in the power supply circuit causing momentary power failure.
      • Identify if there's any equipment causing harmonic wave near the electric line (e.g., neon bulbs).
      • Ensure complete insulation of grounding.
    • Electrical Components:
      • Check the voltage of the power supply at the outdoor unit terminal.
      • Inspect the fuse in the filter PCB; if open, check wiring and replace.
      • Check the varistor in the filter PCB; if defective, replace it after ensuring normal power supply.

    If the power is on but the unit still doesn't operate, check for:

    • Incorrect wiring between the indoor unit and remote controller.
    • Open cable connection.
    • Whether the indoor unit, outdoor unit, and remote controller are suitable model numbers for connection.

    For more information, see pages 222 and 224 of the manual.

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

    If your Fujitsu AUXG07KVLA air conditioner is not responding to the remote, consider the following troubleshooting steps:

    • Wiring and Model Compatibility:
      • Check for incorrect wiring between the indoor unit and remote controller.
      • Ensure the indoor unit, outdoor unit, and remote controller are suitable model numbers for connection.
      • Verify there is no open cable connection.
    • Remote Controller Custom Code:
      • The air conditioner's custom code is set to 'A' prior to shipment. If a custom code other than 'A' is set on the indoor unit, the remote control must be set accordingly to the indoor unit setting. If you don't know the setting, try each custom code (A, B, C, D) until the remote operates the unit.
      • If no buttons are pressed on the remote within 30 seconds after the custom code is displayed, the system returns to the original clock display, and you may need to restart the setting process.

    For more information, see pages 224, 359 and 360 of the manual.

  • How do I fix a blinking light on my Fujitsu AUXG07KVLA air conditioner?

    Blinking lights on your Fujitsu AUXG07KVLA air conditioner indicate an error or malfunction. The specific meaning depends on the pattern of flashes from the Operation, Timer, and Economy indicators. You will need to identify the specific error code to troubleshoot the issue.

    For example:

    • If the Operation indicator flashes 9 times, the Timer indicator flashes 4 times, and the Economy indicator continuously flashes, this indicates an E: 94 Trip detection (Outdoor unit) error. This could be due to issues like a defective outdoor unit fan operation, foreign matter on the heat exchanger, excessive rise of ambient temperature, Main PCB failure, or inverter compressor failure. Troubleshooting steps include checking for obstructions in air passages, clogged heat exchange fins, and the outdoor unit fan motor.
    • If the Operation indicator flashes 10 times, the Timer indicator flashes 1 time, and the Economy indicator continuously flashes, this indicates an E: A1 Discharge temperature error (Outdoor unit). This could be caused by a closed 3-way valve, defective electronic expansion valve (EEV) or capillary tube, clogged strainer, outdoor unit operation failure, discharge temperature thermistor failure, insufficient refrigerant, or Main PCB failure.

    It is recommended to consult the troubleshooting section of the manual for the specific flash pattern your unit is displaying, as many issues require a technical professional for resolution.
