Problem Solution
The air conditioner
makes strange
noises.
• In certain conditions (especially, when the outdoor temperature is
lower than 20°C), a hissing, rumbling, or splashing sound may be
heard while the refrigerant is circulating through the air conditioner.
This is a normal operation.
• When you press the
(Power) button on the remote control, noise
may be heard from the drain pump inside the air conditioner. This
noise is a normal sound.
Unpleasant odours
permeate the
room.
• If the air conditioner is running in a smoky area or if there is a smell
entering from outside, ventilate the room properly.
• If both indoor temperature and indoor humidity are high, operate
the air conditioner in the Clean or Fan mode for 1 to 2 hours.
• If the air conditioner has not been operated for an extended period
of time, clean the indoor unit and then operate the air conditioner
in the Fan mode for 3 to 4 hours to dry the inside of the indoor unit
for removal of unpleasant odours.
• If the air filter blocked with dirt, clean the air filter.
Steam is produced
on the indoor unit.
• In winter, if the indoor humidity is high, steam may be produced
around the air outlet while the defrost function is running. This is a
normal operation.
The outdoor unit
fan continues to
operate when the
air conditioner is
turned off.
• When the air conditioner is turned off, the outdoor unit fan may
continue to operate to reduce noise of the refrigerant gas. This is a
normal operation.
Water drops
from the piping
connections of the
outdoor unit.
• Condensation may develop due to the difference in temperature.
This is a normal condition.
Steam is produced
on the outdoor
unit.
• In winter, when the air conditioner runs in the Heat mode, the frost
on the heat exchanger melts and steam may be produced. This is a
normal operation, neither product malfunction nor a fire.
