Troubleshooting

The following symptoms do not indicate malfunction.

Symptom

Cause

POWER indicator blinks before the unit is 
switched on.

• This is the preliminary step to prepare for the TIMER 

operation after it has been set.
When Timer is set ON, the unit may start earlier up to 
(30 minutes) before the actual set time to achieve the 
desired temperature on time.

TIMER indicator is always ON.

• When Timer has been set, the Timer setting repeats 

daily.

Operation is delayed a few minutes after 
restarting.

• The delay is a protection to the unit’s compressor.

Indoor fan stops occasionally during automatic 
fan speed setting.

• This is to help remove the surrounding odour.

Air

fl

 ow continues even after operation has 

stopped.

• Extraction of remaining heat from the indoor unit

(maximum 30 seconds).

The room has a peculiar odour.

• This may be due to damp smell emitted by the wall, 

carpet, furniture or clothing.

Cracking sound during operation.

• Changes in temperature caused the unit to expand and 

contract.

Water 

fl

 owing sound during operation.

• Refrigerant 

fl

 ow inside the unit.

Mist emerges from indoor unit.

• During cooling operation, the discharged cold air may 

condense to water vapour.

Outdoor unit emits water or steam.

• During cooling operation, condensation occurs on 

cold pipes and the condensed water may drip from the 
outdoor unit.

Louder noise at outdoor unit during early 
operation of i AUTO-X.

• The compressor and fan rotate at higher speed to 

boost cooling performance during initial operation.

Discoloration of some plastic parts.

• Discoloration is subjected to the types of materials 

used in plastic parts. It is accelerated when exposed to 
heat, sun light, UV light or environmental factors.

After extended use, dust may cover the front 
panel, grilles and the wall surrounding the 
unit.

• The dust accumulation is due to the air puri

fi

 cation 

effect of negative ions from nanoe™-G. Remove the 
dust regularly with a clean dampened cloth. 

Soft buzzing sound from indoor unit during 
nanoe™ TECHNOLOGY operation.

• It is normal when the nanoe™X generator is working. 

If you are concerned about the sound, cancel the 
nanoe™ TECHNOLOGY operation.

Wireless LAN indicator is ON when the unit 
is OFF.

• The unit’s wireless LAN connection with the router has 

been activated.
