Troubleshooting

The following symptoms do not indicate malfunction.

Symptom

Cause

POWER indicator blinks before the unit is 

switched on.

• This is a preliminary step in preparation for the 

operation when the ON timer has been set.

• When ON Timer is set, the unit may start earlier (up 

to 30 minutes) before the actual set time in order to 

achieve the desired temperature on time.

TIMER indicator is always on.

• The timer setting repeats daily once set.

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 helps to remove the surrounding odour.

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 of temperature caused the expansion/

contraction of the unit.

Water fl owing sound during operation.

• Refrigerant fl ow inside the unit.

Mist emerges from indoor unit.

• Condensation effect due to cooling process.

Outdoor unit emits water/steam.

• Condensation or evaporation occurs on pipes.

Discoloration of some plastic parts.

• Discoloration is subject to material types used in plastic 

parts, accelerated when exposed to heat, sun light, UV 

light or environmental factor.

Check the following before calling for servicing.
