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.
