Trouble shooting
Before asking for service, check the following first.
Cause or check pointsPhenomenon
The system does not restart
immediately.
When unit is stopped, it won't restart
immediately until 3 minutes have elasped
to protect the system.
When the electric plug is pulled out and
reinserted, the protection circuit will work
for 3 minutes to protect the air conditioner.
Normal
Performance
inspection
Noise is heard:
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
noticeable. (This noise is generated by
refrigerant flowing in the system.)
During unit operation, a cracking noise may
be heard. This noise is generated by the
casing expanding or shrinking because of
temperature changes.
Should there be a big noise from air flow in
unit operation, air filter may be too dirty.
Smells are generated.
This is because the system circulates smells
from the interior air such as the smell of
furniture, cigarettes.
Mist or steam are blown out.
During COOL or DRY operation, indoor unit
may blow out mist. This is due to the sudden
cooling of indoor air.
Multiple
check
Does not work at all.
Is power plug inserted?
Is there a power failure?
Is fuse blown out?
