Problem 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.
• Install a drain hose 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 odor.
Odors (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 center to clean your heat exchanger.
Problem Possible Cause & Solution
Trouble connecting
appliance and
smartphone to Wi-Fi
network
The password for the Wi-Fi network was entered incorrectly.
• Delete your home Wi-Fi network and begin the connection process again.
Mobile data for your smartphone is turned on.
• Turn off the Mobile data on your smartphone before connecting the appliance.
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 appliance and the router are too far apart.
• If the appliance is too far from the router, the signal may be weak and the connection may
not be configured correctly. Move the router closer to the appliance or purchase and
install a Wi-Fi repeater.
