TROUBLE SHOOTING

Trouble Shooting

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

These cases are not troubles.

Case

Explanation

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.

Hot air does not flow out soon 
after the start of heating 
operation.

• The air conditioner is warming up. You should wait for 1 to 4 

minutes.
(The system is designed to start discharging air only after it 
has reached a certain temperature.)

The heating operation stops 
suddenly and a flowing sound 
is heard.

• The system is taking away the frost on the outdoor unit.

You should wait for about 3 to 8 minutes.

The outdoor unit emits water or 
steam.

In HEAT mode
• The frost on the outdoor unit melts into water or steam 

when the air conditioner is in defrost operation.

In COOL or DRY mode
• Moisture in the air condenses into water on the cool 

surface of outdoor unit piping and drips.

Mist comes out of the indoor 
unit.

This happens when the air in the room is cooled into mist by 
the cold airflow during cooling operation.

The indoor unit gives out odour.

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 the service shop where you 
bought the air conditioner.)

The outdoor fan rotates while 
the air conditioner is not in 
operation.

After operation is stopped:
• The outdoor fan continues rotating for another 60 

seconds for system protection.

While the air conditioner is not in operation:
• When the outdoor temperature is very high, the out door 

fan starts rotating for system protection.

The operation stopped 
suddenly.
(OPERATION lamp is on.)

For system protection, the air conditioner may stop 
operating on a sudden large voltage fluctuation.
It automatically resumes operation in about 3 minutes.

No remote controller signals are dis-
played.
The remote controller sensitivity is low.
The display is low in contrast or 
blacked out.
The display runs out of control.

• The batteries are dying and the remote controller is malfunc-

tioning. Replace all the batteries with new size AAA alkaline 
batteries. For details, refer to “To set the batteries” of this 
manual. (page 7.)

 *  If the reset button is provided, press the reset button after the 

batteries are replaced.
