troubleshooting
Before calling for service, check the following:
Problem
The system does
not restart imme-
diately.
Noise
Bad odor
Mist or steam are
blown out
In dry mode, fan
speed can't be
changed.
Possible cause and points to check
• After stopping the unit, it won't restart im-
mediately until 3 minutes have elapsed to
protect the system.
• When the electric plug is pulled out and rein-
serted, the protection circuit will work for 3
minutes to protect the air conditioner.
• During unit operation or at stop, a swishing
or gurgling noise may be heard. At first 2-3
minutes after unit start, this noise is more no-
ticeable. (This noise is generated by refriger-
ant flowing in the system.)
• During unit operation, a cracking noise may
be heard. This noise is generated by the case
expanding or shrinking because of tempera-
ture changes.
• Should there be a big noise from air flow in
unit operation, air filter may be too dirty.
• This is because the system circulates odors
from the interior air such as the odor of furni-
ture, paint, cigarettes.
• During COOL or DRY operation, indoor unit
may blow out mist. This is due to the sudden
cooling of indoor air.
• In DRY mode, when room temperature be-
comes lower than temperature setting +2 °C,
unit will run intermittently at LOW speed re-
gardless of FAN setting.
