Troubleshooting
The followings are not malfunction
Water flowing sound is heard.
Cracking sound is heard.
It smells.
During operation, white fog comes out of
indoor unit.
It is switched into the FAN mode during
cooling.
The air conditioner can not be restarted soon
after it stops.
Air does not blow or the fan speed can not be
changed during dehumidifying
During operation, operation mode has changed
over automatically.
Water or steam generates from the outdoor
unit during heating.
When the air conditioner is started, when the compressor starts or stops during
operation or when the air conditioner is stopped, it sometimes sounds "shuru
shuru" or "gobo gobo". It is the flowing sound of the refrigerant, and it is not a
trouble.
This is caused by heat expansion or contraction of plastics.
Air which blows out from the indoor unit sometimes smells. The smell results
from residents of tobacco smoke or cosmetics stuck inside of unit.
When the air conditioner is used at restaurant etc. where dense edible oil fume
is always exists, white fog sometimes blows out of air outlet during operation.
In this case consult sales dealer for cleaning the heat exchanger.
To prevent frost from being accumulated on the indoor unit heat exchanger, it
is sometimes automatically switched to the FAN mode but it will soon return
to the cooling mode.
Even if the operation switch is turned on, cooling, dehumidifying or heating is
not operable for three minutes after the conditioner is stopped. Because the
protecting circuit is activated.
(During this time air conditioner operates in fan mode.)
When it is excessively cooled during dehumidifying, the blower automatically
repeats reducing and lowering the fan speed.
Unit does
not start
Isn't the AUTO mode selected?
In the case of AUTO mode, operation mode is changed automatically from
cooling to heating or vise-versa according to the room temperature.
This results when frost accumulated on the outdoor unit is removed (during
defrosting operation).
