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.
