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.
