Troubleshooting
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 outdoor 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
displayed.
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.
