Problem Solution
The air conditioner stops
working.
• Make sure the unit is receiving power.
• Check the circuit breaker. If it is flipped off, flip it on again and
restart the unit. If the problem persists, contact your service
provider.
• The Timed off function may have turned off the unit. Turn on the
unit again.
Cannot change the
temperature.
• Check if the unit is in Fan or Fast mode. If so, you cannot change
the set temperature; the unit automatically controls the set
temperature.
Improper airflow temperature.
• Check the set temperature. In Cool mode, cooling occurs only
when the set temperature is lower than the current temperature.
In Heat mode, heating occurs only when the set temperature is
higher than the current temperature.
• Use
the (Temperature) button
on the remote control to change
the set temperature.
• Check if the air filter is blocked with dirt or debris. If the air filter
is blocked, the cooling and heating performance may decrease.
Clean the air filter regularly (page 34).
• Check if the outdoor unit is covered or is installed near obstacles.
Remove the coverings and obstacles.
• Check if the Defrost function is on (page 21). During defrost,
the fan stops and warm air does not come out.
• Check if doors or windows are open. This may cause poor
circulation or performance. Close all doors and windows.
• Check if the pipe length between the units exceeds the maximum
pipe length (see “Typical installation” in the Installation manual). If
so, the cooling and heating performance may decrease.
Cannot change the airflow
direction.
• Check if the good'sleep function is on in Cool mode. If so, you
cannot control the airflow direction.
Cannot change the fan speed.
• Check if the unit is in Auto, Dry, or Fast mode or the good'sleep
function is on in Cool mode. In these conditions, you cannot
control the fan speed; the unit automatically controls the fan
speed.
If the air conditioner is not operating normally, refer to the troubleshooting guide below.

Problem Solution
The remote control does not
work.
• Replace the batteries in the remote control.
• Make sure the remote control can send an unobstructed signal to
the unit.
• Keep bright lights away from the unit. Light from fluorescent
bulbs or neon signs may interrupt the signal from the remote
control.
The Timed on/off function
does not work.
• Make sure to press the
(SET) button on the remote control
when setting the timer.
The indicator on the remote
control blinks continuously.
• Press the
(Power) button to turn off the unit, or disconnect
the power plug.
• If the indicator light on the remote control continues blinking,
contact your service provider.
Odors are coming from the
unit during regular operation.
• If the unit is operating in a smoky area, ventilate the room or
operate the unit in Fan mode for 3 to 4 hours. There are no
components in the unit that produce a strong odor.
• Check if the drain lines are clean. Clean them regularly.
The remote control display
shows an error message.
• If the indoor unit indicator blinks, write down the error code.
Contact your service provider and provide them with the error
code.
The unit is generating noise.
• It is normal for the unit to generate some noise while operating.
If the pipe length between the units is less than 3 m and no coil
was used (see “Typical installation” in the Installation manual),
additional noise may be transmitted from the outdoor unit to the
indoor unit via the piping.
Smoke is coming from the
outdoor unit.
• In winter, most likely this is steam coming from the outdoor heat
exchanger while the Defrost function is on.
Water drips from the pipe
connections on the outdoor
unit.
• Condensation may develop when the ambient temperature or
humidity changes significantly. This is normal.
Condensation forms on the
surface of the indoor unit.
• If the humidity is higher in the room in Cool mode, or the
difference between the desired temperature and indoor
temperature is great, condensation may form on the surface of
the indoor unit.
