Troubleshooting
Refer to the following chart if the air conditioner operates abnormally. This may save time and unnecessary
expense.
Problem Solution
The air conditioner
does not operate
immediately after it
has been restarted.
• Because of the protective mechanism, the appliance does not start operating
immediately to keep the unit from overloading. The air conditioner will start in
3 minutes.
The air conditioner
does not operate at
all.
• Check whether the power is turned on, and then operate the air conditioner
again.
• Check whether the auxiliary power switch (MCCB, ELB) is turned on.
• If the auxiliary power switch (MCCB, ELB) is turned off, the air conditioner does
not work although you press the (Power) button.
• When you clean the air conditioner or do not use it for an extended period of
time, turn off the auxiliary power switch (MCCB, ELB).
• After the air conditioner is not used for an extended period of time, be sure
to turn on the auxiliary power switch (MCCB, ELB) 6 hours before starting
operation.
NOTE
• The auxiliary power switch (MCCB, ELB) is sold separately.
• Make sure that auxiliary power switch (MCCB, ELB) is installed in the
distribution box inside the building.
• If the air conditioner is turned off by the Timed off function, turn on the air
conditioner again by pressing the (Power) button.
The temperature
does not change.
• Check whether the Fan mode is running. In the Fan mode, the air conditioner
controls the set temperature automatically, and you cannot change the set
temperature.
Warm airdoes not
come out of the air
conditioner.
• Check whether the outdoor unit is designed for cooling only. In this case, warm
air does not come out although you select the Heat mode.
• Check whether the remote control is designed only for cooling only. Use a
remote control that supports both cooling and heating.

Problem Solution
The fan speed does
not change.
• Check whether the Auto or Dry mode is running. In these modes, the air
conditioner controls the fan speed automatically, and you cannot change the
fan speed.
The wireless remote
control does not
operate.
• Check whether the batteries are discharged. Replace the batteries with new ones.
• Make sure that nothing is blocking the remote control sensor.
• Check whether any strong lighting sources are near the air conditioner. Strong
light which comes from uorescent bulbs or neon signs may interfere with the
remote control.
The wired remote
control does not
operate.
• Check whether the indicator is displayed at the bottom right of the remote
control display. In this case, turn off both the air conditioner and the auxiliary
power switch, and then contact a service centre.
The air conditioner
is not turned on or
off immediately with
the wired remote
control.
• Check whether the wired remote control is set for group control. In this case,
the air conditioners connected to the wired remote control are turned on or off
sequentially. This operation takes up to 32 seconds.
The Timed on/off
function does not
operate.
• Check whether you pressed the (SET) button on the remote control after
setting the on/off time. Set the on/off time.
The indoor unit
display blinks
continuously.
• Turn on the air conditioner again by pressing the (Power) button.
• Turn off and then turn on the auxiliary power switch, and then turn on the
conditioner.
• If the indoor unit display is still blinking, contact a service centre.
I want to get cooler

The air is not cool or
warm enough.
• In the Cool mode, cool air does not come out if the set temperature is higher
than the current temperature.
–AR-EH0**, AR-EC0** remote control: Press the Temperature button
repeatedly until the set temperature (minimum: 64℉(18℃)) is set to lower
than the current temperature.
–AR-KH0** remote control: Press the Temperature button on the remote
control. Then rotate the Wheel until the set temperature
(minimum: 64℉(18℃)) is set to lower than the current temperature.
• In the Heat mode, warm air does not come out if the set temperature is lower
than the current temperature.
–AR-EH0**, AR-EC0** remote control: Press the Temperature button
repeatedly until the set temperature (maximum: 86℉(30℃)) is set to
higher than the current temperature.
–AR-KH0** remote control: Press the Temperature button on the remote
control. Then rotate the Wheel until the set temperature
(maximum: 86℉(30℃)) is set to higher than the current temperature.
• Both cooling and heating do not operate in the Fan mode. Select the Cool,
Heat, Auto, or Dry mode.
• Check whether the air lter is blocked with dirt. A dusty lter may decrease the
cooling and heating efciencies. Clean the air lter frequently.
• If a cover is on the outdoor unit or any obstacle is present near the outdoor
unit, remove them.
• Install the outdoor unit in a well-ventilated place. Avoiding places exposed to
direct sunlight or close to a heating appliance.
• Place a sunscreen over the outdoor unit to protect it from direct sunlight.
• If the indoor unit is installed in a place exposed to direct sunlight, pull the
curtains on the windows.
• Close the windows and doors to maximize the cooling and heating efciencies.
• If the Cool mode is stopped and then started immediately, cool air comes out
after about 3 minutes to protect the compressor of the outdoor unit.
• When the Heat mode is started, warm air does not come out immediately to
prevent cool air from coming out at the beginning.
• If the refrigerant pipe is too long, the cooling and heating efciencies may be
decreased. Avoid exceeding the maximum pipe length.

Problem Solution
The air conditioner
makes strange
noises.
• In certain conditions (especially, when the outdoor temperature is lower than
68℉(20℃)), 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 for1 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
