Troubleshooting

■

These cases are not troubles.

• The following cases are not air conditioner troubles but have some reasons. You may just continue using it.

Indoor unit

Outdoor unit

The HEAT operation stops suddenly 

and a 

fl

 owing sound is heard.

•   The outdoor unit is taking away the frost.

The HEAT operation starts after the frost on the outdoor 
unit is removed. You should wait for about 4 to 12 minutes.

Operation does not start soon.

■

  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 

fl

 aps do not start swing 

immediately.

•   The air conditioner is adjusting the 

fl

 aps position. 

The 

fl

 aps will start moving soon.

A sound is heard.

■

  A sound like a 

fl

 ow of water

•   This sound is generated because the refrigerant in 

the air conditioner is 

fl

 owing.

•   This is a pumping sound of the water in the air 

conditioner and heard when the water is pumped out 
from the air conditioner in cooling or drying operation.

•   The refrigerant 

fl

 ows in the air conditioner even if the 

air conditioner is not working when the indoor units 
in other rooms are in operation.

■

  Blowing sound

•   This sound is generated when the 

fl

 ow of the 

refrigerant in the air conditioner is switched over.

■

  Ticking sound

•   This sound is generated when the size of the air conditioner 

slightly expands or shrinks as a result of temperature changes.

■

Whistling sound

•   This sound is generated when refrigerant 

fl

 ows 

during defrosting operation.

■

  Clicking sound during operation or idle time

•   This sound is generated when the refrigerant control 

valves or the electrical parts operate.

■

 Clopping  sound

•   This sound is heard from the inside of the air conditioner 

when the exhaust fan is activated while the room doors 
are closed. Open the window or turn off the exhaust fan.

The outdoor unit emits water or steam.

■

 In HEAT operation 

•   The frost on the outdoor unit melts into water or steam when the air conditioner is 

in defrost operation.

■

 In COOL or DRY operation 

•   Moisture in the air condenses into water on the cool surface of outdoor unit piping 

and drips.

The air conditioner stops generating 
air

fl

 ow during operation.

•   Once the set temperature is reached, the air

fl

 ow rate 

is reduced and operation stopped in order to avoid 
generating cool air

fl

 ow (during heating) or in order to 

keep the humidity from rising (during cooling). 
Operation will resume automatically when the indoor 
temperature rises or falls.
