Cause or check pointsPhenomenon
The system does not restartimmediately.
Noise is heard:
Smells are generated.
Mist or steam are blown out.
Does not work at all.Multiplecheck
NormalPerformanceinspection
Poor cooling
Before asking for service, check the following first.
When unit is stopped, it won't restartimmediately until 3 minutes have elapsedto protect the system.When the electric plug is pulled out andreinserted, the protection circuit will workfor 3 minutes to protect the air conditioner.
During unit operation or at stop, a swishingor gurgling noise may be heard. At first 2-3minutes after unit start, this noise is morenoticeable. (This noise is generated byrefrigerant flowing in the system.)During unit operation, a cracking noise maybe heard. This noise is generated by thecasing expanding or shrinking because oftemperature changes.Should there be a big noise from air flow inunit operation, air filter may be too dirty.
This is because the system circulates smellsfrom the interior air such as the smell offurniture, cigarettes.
During COOL or DRY operation, indoor unitmay blow out mist. This is due to the suddencooling of indoor air.
Is power plug inserted?Is there a power failure?Is fuse blown out?
