Case Explanation
Mist is discharged from the air
outlet of the indoor unit
- The cool air from the unit rapidly cools moisture in the air inside the
room, and it turns into mist.
Operation does not start
quickly.
- When ON/OFF button was
pressed soon after operation
was stopped.
- When the mode was
reselected.
- This is to protect the air conditioner. You should wait for about 3 minutes.
The indoor unit gives out odor. - This happens when smells of the room, furniture, or cigarettes are
absorbed into the unit and discharged with the airflow. (if this happens, we
recommend you to have the indoor unit washed by a technician. Consult
your authorized dealer where you bought the air conditioner.)
Water leak from the outdoor
unit.
- During COOL and DRY operation, pipe or pipe connecting sections are
cooled and this causes water to condense.
Cracking sound is heard. - This sound is generated by the expansion/contraction of the front panel,
etc. due to change in temperature.
"Burbling" sound is heard. - This sound is heard when the outside air is absorbed from the drain hose
by turning on the range hood or the ventilation fan, making water flowing
in the drain hose to spout out. This sound is also heard when the outside
air blows into the drain hose in case the outside wind is strong.
Mechanical sound is heard from
the indoor unit.
- This is the switching sound in turning on/off the fan or the compressor.
The sound of water flowing is
heard.
- This is the sound of refrigerant or condensed water flowing in the unit.
