Symptom
Cause
It is not a failure.
Outdoor
unit
• White, misty, cold air or water

• The fan of the outdoor unit is automatically stopped
and defrosting is performed.

leaking is heard.
• The solenoid valve works when defrosting starts or
stops.
• A noise is heard when the
power is turned on.
• The outdoor unit is preparing for running.
Indoor
unit
• Sometimes a swishing is
heard.
• When the unit starts running, during operation, or
immediately after the unit stops running, a sound
such as water
fl
owing may be heard, or the operation
sound may become louder for a couple of minutes
immediately after the unit starts running. This is the
sound of the refrigerant
fl
owing or the dehumidi
fi
er
draining.
• A clacking sound is heard.
• This is a sound generated when the heat exchanger
or other part expands and contracts slightly due to
temperature change.
• Discharged air smells unusual. • Various smells from the walls, carpet, clothes,
cigarette, cosmetics or other things adhere to the air
conditioner.
• The fan continues running
even after the unit operation is
stopped.
• The fan keeps running to self clean the heat
exchanger during drying.
• The unit does not run.
• Has a blackout occurred?
• Has the circuit breaker blown?
• Has the protective device been activated?
(The operation indicator and on the remote controller
are blinking.)
Check again.
The room does not cool down.
• Is the air intake or discharge of the outdoor unit
clogged?
• Is a door or window open?
• Is the air
fi
lter clogged with dust?
• Is the air volume set to “LOW”? or is the operation
mode set to “FAN”?
• Is the setup temperature appropriate?
If there is something unusual even after checking the above, stop running the unit, turn off the circuit
breaker, and inform the dealer where you purchased the product of the product number and symptom. Do
not attempt to repair the unit by yourself as doing so is dangerous. If the check indicator (e.g. , , )
is displayed on the remote controller LCD, inform the dealer of its content as well.
If any of the following occur, stop running the unit immediately, turn off the circuit breaker, and contact the
dealer where you purchased the product.
• The switch does not work properly.
• The circuit breaker often blows out.
• You unintentionally put a foreign object or water inside.
• The unit cannot be run even after the cause of the protective device activation is removed.
