The operation light continues to flash rapidly after the unit has been restarted.

 

 

The remote-control buttons do not work.

 

 

The unit continually trips fuses or circuit breakers.

 

 

A foreign object or water enters the air conditioner.

 

 

Other abnormal situations.

 

 

 Common Problems 

 

 

The following symptoms are not a malfunction and in most situations, will not require repairs.

 

 

Problem 

Possible Causes

 

 

Unit does not 
turn on when 
pressing ON/ 
OFF button

 

The unit has a 3-minute protection feature that prevents the unit from 

overloading. The unit cannot be restarted within three minutes of being 

turned off.

 

Cooling and Heating Models: If the Operation light and PRE-DEF (Pre-heating/ 

Defrost) indicators are lit up, the outdoor temperature is too cold and the unit’s 

anti-cold wind is activated in order to defrost the unit.

 

In Cooling-only Models: If the “Fan Only” indicator is lit up; the outdoor 

temperature is too cold and the unit’s anti-freeze protection is activated in 

order to defrost the unit.

 

 

The unit changes 

from COOL mode 
to FAN mode

 

The unit changes its setting to prevent frost from forming on the unit. Once 

the temperature increases, the unit will start operating again.

 

The set temperature has been reached, at which point the unit turns ou the 

compressor. The unit will resume operating when the temperature fluctuates 

again.

 

The indoor unit 
emits white mist

 

In humid regions, a large temperature difference between the room’s air and 

the conditioned air can cause white mist.

 

Both the indoor 

and outdoor units 

emit white mist

 

 

When the unit restarts in HEAT mode after defrosting, white mist may be 

emitted due to moisture generated from the defrosting process.
