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
HEAT operation stops suddenly
and a
fl
owing sound is heard.
The outdoor unit is defrosting.
•
HEAT operation starts after the frost on the outdoor unit
has been removed. This can take about 4 to 12 minutes.
Operation does not start soon.
When
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 swinging
immediately.
The air conditioner is adjusting the position of the
•
fl
aps. The
fl
aps will start moving soon.
Different sounds are heard.
A sound like
fl
owing 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 during COOL or DRY 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 cabinet and frame
•
of the air conditioner slightly expand or shrink 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 defrosting operation.
In COOL or DRY operation
Moisture in the air condenses into water on the cool surface of the outdoor unit
•
piping and drips.
The air conditioner stops generating
air
fl
ow during HEAT 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. Operation will resume
automatically when the indoor temperature falls.
