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.
Answer (not a malfunction)
■ This protects the air conditioner according to instruc-
tions from the microprocessor. Please wait.
■ This sound is generated by the expansion/contraction
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 opera-
tion 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 defrosting.
