Troubleshooting
These cases are not troubles.
The following cases are not air conditioner troubles but have some reasons. You may just continue using it.
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
fl
ow out soon after
the start of HEAT 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 HEAT operation stops suddenly
and a
fl
owing sound is heard.
The system is taking away the frost on the outdoor unit.
•
You should wait for about 4 to 12 minutes.
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.
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.
Mist comes out of the indoor unit.
This happens when the air in the room is cooled into mist by the cold air
fl
ow
during cooling operation.
This is because the air in the room is cooled by the heat exchanger and
becomes mist during defrost 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 air
fl
ow.
(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.)
