TROUBLESHOOTING
■ Normal Operation
Is it okay?
• Air conditioner has been restarted, but does not
operate for 3 minutes.
• A sound like water flowing can be heard.
• It seems that fog is coming out from the air
conditioner.
• The room has a peculiar odor.
• During Automatic Vertical Airflow setting,
indoor fan stops occasionally.
• The outdoor unit emits water or steam.
• (For Heat Pump Model only)
Operation stops for about 12 minutes during
heating (The power indicator blinks.)
• (For Heat Pump Model only)
During heating operation, indoor fan may
run at on and off conditions.
■ Abnormal Operation
Solution
• This is to protect the air conditioner. Wait until the air
conditioner begins to operate.
• This is the sound of refrigerant flowing inside the air
conditioner.
• Condensation occurs when the airflow from the air
conditioner cools the room.
• This may be a damp smell emitted by the wall,
carpet, furniture or clothing in the room.
• This is to remove smell emitted by the surroundings.
• In COOL/DRY operation, moisture in the air
condenses into water on the cool surface of outdoor
unit piping that causes dripping.
• This is to melt the frost which has accumulated on
the outdoor unit (defrosting operating). This will take
no longer than about 12 minutes. Water drips from
the outdoor unit. Wait until this operation ends. (The
power indicator will light up.)
(Frost accumulates on the outdoor unit when the
outdoor temperature is low and humidity is high.)
• This is to prevent undesired cooling effect during
heating operation.
