• Some functions may not be supported, depending on the model. Self-Diagnosis Function This appliance has a built-in self-diagnosis function. If an error occurs, the lamp of the indoor unit will flash in 2-second intervals. If this occurs, contact your local dealer or service centre. Operation Symptoms Possible Cause & SolutionThe appliance does not work normally.Burning smell and strange sounds are coming from the appliance.• Turn off the appliance, switch off or disconnect the power supply, and contact the service centre.Water leaks from the indoor unit even when the humidity level is low.• Turn off the appliance, switch off or disconnect the power supply, and contact the service centre.The power cable is damaged or it is generating excessive heat.• Turn off the appliance, switch off or disconnect the power supply, and contact the service centre.A switch, a circuit breaker (safety, ground) or a fuse is not operating properly.• Turn off the appliance, switch off or disconnect the power supply, and contact the service centre.The appliance generates an error code from its self-diagnosis.• Turn off the appliance, switch off or disconnect the power supply, and contact the service centre.The fan speed cannot be adjusted.The Jet mode or Auto Operation mode is selected.• In some operating modes, you cannot adjust the fan speed. Select an operating mode in which you can adjust the fan speed.The temperature cannot be adjusted.The Fan mode or Jet mode is selected.• In some operating modes, you cannot adjust the temperature. Select an operating mode in which you can adjust the temperature.43 TROUBLESHOOTING ENGLISH The appliance stops during operation. The appliance is suddenly turned off.

• The Off Timer function may have timed out, which turns the appliance off. Check the timer settings. A power failure has occurred during operation.

• Wait for the power to come back on. If you have the Auto Restart function enabled, your appliance will resume its last operation several minutes after power is restored. The appliance does not work. The appliance is unplugged.

• Check whether the power cord is plugged into the outlet or the power isolators are switched on. A fuse exploded or the power supply is blocked.

• Replace the fuse or check if the circuit breaker has tripped. A power failure has occurred.

• Turn off the appliance when a power failure occurs.

• When the power is restored, wait 3 minutes, and then turn on the appliance. The voltage is too high or too low.

• Check if the circuit breaker has tripped. The appliance was turned off automatically at a preset time.

• Turn the appliance on. The battery setting in the wireless remote control is incorrect.

• Make sure that the batteries are inserted correctly in your wireless remote control.

• If the batteries are placed correctly, but the appliance still does not operate, replace the batteries and try again. The appliance does not emit cool air. Air is not circulating properly.

• Make sure that there are no curtains, blinds, or pieces of furniture blocking the front of the appliance. The air filter is dirty.

• Clean the air filter once every 2 weeks.

• See “ Cleaning the Air Filter ” for more information. The room temperature is too high.

• In summer, cooling the indoor air fully may take some time. In this case, select the Jet mode to cool the indoor air quickly. Cold air is escaping from the room.

• Make sure that no cold air is escaping through the ventilation points in the room. Symptoms Possible Cause & Solution44 TROUBLESHOOTING Performance The appliance does not emit cool air. The target temperature is higher than the current temperature.

• Set the target temperature to a level lower than the current temperature. There is a heating source nearby.

• Avoid using heat generators like electric ovens or gas hobs while the air conditioner is in operation. Fan mode is selected.

• During Fan mode, air blows from the appliance without cooling or heating the indoor air.

• Switch the operating mode to cooling operation. Outside temperature is too high.

• The cooling effect may not be sufficient. Symptoms Possible Cause & Solution The indoor unit is still operating even when the appliance has been turned off. The Auto Clean function is being operated.

• Allow the Auto Clean function to continue since it reduces any remaining moisture inside the indoor unit. If you do not want this function, you can turn the indoor unit off. The air outlet on the indoor unit is discharging mist. The cooled air from the appliance makes mist.

• When the room temperature decreases, this phenomenon will disappear. Water leaks from the outdoor unit. In the heating operations, condensed water drops from the heat exchanger.

• This requires that a drain hose should be installed under the base pan. Contact the installer. There is noise or vibration. A clicking sound can be heard when the appliance starts or stops due to movement of the reversing valve. Creaking sound: The plastic parts of the indoor unit creak when they shrink or expand due to sudden temperature changes. Flowing or blowing sound: This is the flow of refrigerant through the appliance.

• Noise is normal during or after operation. It is not a sign of malfunction. The indoor unit gives off an odour. Odour (such as cigarette smoke) may be absorbed into the indoor unit and discharged with airflow.

• If the smell does not disappear, you need to wash the filter. If this does not work, contact the service centre to clean your heat exchanger. Symptoms Possible Cause & Solution45 TROUBLESHOOTING ENGLISH Wi-Fi The appliance does not emit warm air. When the Heating mode starts, the vane is almost closed, and no air comes out, even though the outdoor unit is operating.

• This is normal. Please wait until the appliance has generated enough warm air to blow through the indoor unit. The outdoor unit is in Defrosting mode, the vane is almost closed, and no air comes out, even though the outdoor unit is operating.

• In Heating mode, ice and frost is built up on the coils when the outside temperature falls. The Defrosting mode reduces a layer of frost on the coil, and it should finish in approximately 15 minutes. Outside temperature is too low.

• The heating effect may not be sufficient. Symptoms Possible Cause & Solution Your home appliance and smartphone are not connected to the Wi-Fi network. The password for the Wi-Fi that you are trying to connect to is incorrect.

• Find the Wi-Fi network connected to your smartphone and remove it, then register your appliance on LG ThinQ

Mobile data for your smartphone is turned on.

• Turn off the Mobile data of your smartphone and register the appliance using the Wi-Fi network. The wireless network name (SSID) is set incorrectly.

• The wireless network name (SSID) should be a combination of English letters and numbers. (Do not use special characters.) The router frequency is not 2.4 GHz.

• Only a 2.4 GHz router frequency is supported. Set the wireless router to 2.4 GHz and connect the appliance to the wireless router. To check the router frequency, check with your Internet service provider or the router manufacturer. The distance between the appliance and the router is too far.

• If the distance between the appliance and the router is too far, the signal may be weak and the connection may not be configured correctly. Move the location of the router so that it is closer to the appliance. Symptoms Possible Cause & SolutionMemoMemoРЪКОВОДСТВО ЗА ЕКСПЛОАТАЦИЯ
