Troubleshooting Guide
Problem Possible cause and solution
The air conditioner
does not work at all.
Check and ensure there is no power failure or
blown fuse. Also check the timer and ensure the
unit is not set to start operating at a later time.
Poor cooling or
heating performance.
Check and ensure that the room temperature
setting is appropriate, that window(s) and door(s)
are closed and that the filters are clean.
Poor cooling
performance.
Check and ensure that no direct sunlight is
entering the room and that there are no heat
sources in the room. A large number of people
in the room may also affect the unit’s cooling
performance.
The unit cannot be
restarted just after
shutdown (running
indicator is illuminated).
After shutting down the unit, you will have to wait
for 3 minutes before it can be restarted. This is an
internal protection mechanism.
Air is not blown out at
the start of the heating
operation.
In order to prevent cold air being blown out in
Heating mode, airflow is prevented until the indoor
heat exchanger has warmed up the air sufficiently.
This may take 2 to 5 minutes.
In Heat mode, air is
not blown out for 6 to
12 minutes.
On very cold days with high humidity, the air
conditioner may perform an automatic defrosting
cycle during which water or steam may raise from
the outdoor unit. Please wait; heating operation
will start automatically after the defrosting cycle.
Air is not blown out in
Dry mode.
In Dry mode, the indoor fan is sometimes stopped
to save energy and prevent steam generation from
moisture evaporation.
Mist is blown out in
Cool mode.
This phenomenon sometimes occurs when the
temperature and humidity in the room are very
high. It will disappear as the temperature and
humidity in the room are lowered.
A cracking noise can
be heard.
This is caused by the refrigerant that is circulating
inside the unit. It is no cause for concern.
If you experience problems with your air conditioner, check for solutions in
the table below. If the problem cannot be solved by simple adjustments, call
the after sales support line, or contact a licensed air conditioner technician.
