Problem Possible Causes Corrective Action
The indoor unit is
still operating even
when the unit has
been turned off.
The Auto Clean function is
being operated.
• Allow the Auto Clean function to continue since
it removes any remaining moisture inside the
indoor unit. If you do not want this feature, you
can turn the unit off.
The air outlet on
the indoor unit is
discharging mist.
The cooled air from the air
conditioner 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 symptom requires installing a drain hose
under the base pan. Contact the installer.
There is noise or
vibration.
A clicking sound can be
heard when the unit 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 air conditioner.
• These are normal symptoms. The noise will
stop.
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.
The air conditioner
does not emit warm
air.
When Heating Mode starts, the
vane is almost closed, and no
air comes out, even though
the outdoor unit is operating.
• This symptom is normal. Please wait until the
unit has generated enough warm air to blow
through the indoor unit.
The outdoor unit is in
Defrosting Mode.
• In Heating Mode, ice/frost is built up on the
coils when the outside temperature falls.
This function removes 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.
