Problem
The air-conditioner
stops during operation.
Indoor unit is still oper-
ating even when the
power has been
turned off.
The air outlet on the
indoor unit is discharg-
ing mist.
Water leaks from the
outdoor unit.
Operating noise or
vibration.
The indoor unit gives
out odor.
Possible causes
• The air conditioner is sud-
denly turn off.
• A power failure has
occurred during opera-
tion.
• Auto-Clean mode is being
operated.
• The cooled air from the
air conditioner makes
mist.
• In the heating operations,
condensed water drop
from the heat exchanger.
• Clicking sound
Clicking sound can be
heard either when the
unit starts or stops due to
movement of reversing
valve.
• Creaking sound
The plastic parts of the
indoor unit creak when
shrinking or expanding
due to sudden tempera-
ture changes.
• Flowing or Blowing sound
This is the flow of refrig-
erant through the air con-
ditioner.
• Odors (such as cigarette
smoke) may be absorbed
into the indoor unit and
discharged with airflow.
Corrective action
• The Timer Function may have timed out,
which turns the unit off. Check the timer
settings.
• Wait for the power to come back. If you
have the Auto Restart Function enabled,
your unit will resume its last operation
several minutes after the power is
restored.
• Allow the Auto-Clean to continue as it
removes any remaining moisture inside
the indoor unit. If you do not want this
feature to continue, you can turn the unit
off.
• When the room temperature decreases,
this phenomenon will disappear.
• This symptom need to install drain hose
under the base pan. Contact the installer.
• These are normal symptoms. The noise
will stop.
• If the smell does not disappear, you
need to wash the filter. If this does not
work, contact a qualified HVAC techni-
cian to clean your heat exchanger.
