WHEN YOU THINK THAT TROUBLE HAS OCCURRED
Question
The air conditioner
cannot be operated
for about 3 minutes
when restarted.
Cracking sound is
heard.
The room smells
strange.
The fan stops during
the DRY operation.
The sound of water
flowing is heard.
The sound as burbling
is heard.
Answer (not a malfunction)
■
This protects the air conditioner according to in-
structions from the microprocessor. Please wait.
■
This sound is generated by the expansion/con-
traction of the front panel, etc. due to change in
temperature.
■
The air conditioner sucks in an odor adhering to
the wall, carpet, furniture, cloth, etc. and blows it
out with the air.
■
In DRY operation, the unit operates using the
same refrigerant circuit as in COOL operation.
DRY operation time has to be reduced in order to
lower humidity without much room temperature
decreasing. So the compressor sometimes stops,
and at the same time the indoor fan stops. This
prevents water condensed on the heat exchanger
from evaporating again.
■
This is the sound of refrigerant flowing inside the
air conditioner.
■
This is the sound of condensed water flowing in
the heat exchanger.
■
This is the sound of the heat exchanger defrost-
ing.
■
This sound is heard when the outside air is ab-
sorbed from the drain hose in turning on the
range hood or the ventilation fan and that makes
water flowing in the drain hose spout out.
This sound is also heard when the outside air
blows into the drain hose in case the outside wind
is strong.
■
When a ventilation fan or a gas cooker is used in
a room, the cooling load increases, resulting in
an insufficient cooling effect.
■
When the outside air temperature is high, the
cooling effect may not be sufficient.
■
When the air conditioner is operated in COOL or
DRY mode, if the operation continues with air
blowing down for 1 hour, the direction of the air
flow is automatically set to horizontal to prevent
condensed water from dropping.
■
During COOL and DRY operations, pipe or pipe
connecting sections are cooled and this causes
water to condense.
■
This is for the swing operation of the VERTICAL
VANE to be performed normally.
Question
Answer (not a malfunction)
The room cannot be
cooled sufficiently.
The air flow direc-
tion changes dur-
ing operation.
Water leak from the
outdoor unit.
The swing operation of
the VERTICAL VANE is
suspended for about
15 seconds, then re-
started.
