Symptom Explanation & Check points
Sound
Cracking sound is heard. • This sound is generated by the expansion/
contraction of the panel, etc. due to change in
temperature.
“Burbling” sound is heard. • This sound is heard when the outside air is
absorbed from the drain hose by turning on the
range hood or the ventilation fan, making water
owing in the drain hose to spout out.
This sound is also heard when the outside air
blows into the drain hose in case the outside
wind is strong.
Mechanical sound is heard
from the indoor unit.
• This is the switching sound in turning on/o the
fan or the compressor.
The sound of water owing is
heard.
• This is the sound of refrigerant or condensed
water owing in the unit.
Hissing sound is sometimes
heard.
• This is the sound when the ow of refrigerant
inside the unit is switched.
The sound of motor and swirl-
ing sound is heard from the
indoor unit.
• This is the sound of water condensed during
cooling operation/dry operation being drained
from the indoor unit.
• Sound of water draining may also be heard from
indoor units which are not operating. (The sound

Heating operation stops and
the sound is heard.
• The outdoor unit is defrosting.
Heating operation starts after the frost on the

sound from the indoor unit. If information fails to
be received, 3 short beeps will be heard. Ensure
information is successfully received.

• When a power failure occurs and the main power
turns o, the indoor unit built-in clock will be
incorrect. As a result, the weekly timer may not
work normally.
Be sure to place the remote controller where
the signal can be received by the indoor unit.
