Problem
The indoor unit is
still operating even
when the appliance
has been turned off.
The air outlet on the
indoor unit is
discharging mist.
Water leaks from the
outdoor unit.
There is noise or
vibration.
Crack sound is heard. This sound is generated by the expansion or constriction of the front panel, etc. due to
Outside temperature is too high.
• The cooling effect may not be sufficient.
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.
• 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.
When the appliance reaches the desired temperature, the airflow rate reduces in order
to avoid generating cool airflow during heating, or to minimize energy consumption
and indoor humidity change during cooling.
• This symptom is normal.
Condensation occurs when the airflow from the air conditioner cools the warm room
air.
• This symptom is normal.
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 cooled air from the appliance makes mist.
• When the room temperature decreases, this phenomenon will disappear.
In the heating operations, condensed water drops from the heat exchanger.
• Install a drain hose under the base pan. Contact the installer.
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.
• Noise is normal during or after operation. It is not a sign of malfunction.
Flowing sound: This is the flow of refrigerant through the appliance.
Blowing sound: This sound generates when compressed air is released into the
atmosphere.
This is the sound of the dehumidifying water being processed inside the air
conditioning unit.
• These are normal symptoms. The noise will stop.
changes of temperature.
• These are normal symptoms. The noise will stop.
