Symptoms Possible Causes & Solution
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.
