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 odour.
• During Automatic Airflow setting, indoor fan
stops occasionally.
• The outdoor unit emits water or steam.
Abnormal Operation
Is it okay?
• The air conditioner does not operate.
• Air conditioner produces loud noise during
operation.
• The air conditioner does not cool effectively.
This is the answer
• 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.
Please check
• Has the circuit breaker been tripped?
• Is the timer being used correctly?
• Is the installation work slanted?
• Is the front grille closed properly?
• Has the temperature been set incorrectly?
• Are the filters dirty?
• Are the intake or outlet vents of the outdoor unit
obstructed?
• Are all windows and doors closed?
