■ Troubleshooting
If your air conditioner does not work properly, first check the following points before requesting service. If it still does not work
properly, contact your dealer or a service center.
●
Indoor unit
Symptom
Noise
Sound like streaming water during
operation or after operation.
Cracking noise during operation or
when operation stops.
Odor
Discharged air is smelled during
operation.
Dewdrop
Dewdrop gets accumurated near air
discharge during operation.
Fog
Fog occurs during operation in
cooling mode.
(Places where large amounts of oil
mist exist at restaurants.)
Fan is rotating for a while even though operation
stops.
Wind-direction changes while operating.
Wind-direction setting cannot be made.
Wind-direction cannot be changed.
When wind-direction is changed, flap operates
several times and stops at designated position.
Dust
At the initial high-speed operation, the fan may
sometimes rotate faster (for 3 to 30 minutes) than
the setting speed.
●
Sound of refrigerant liquid flowing inside unit
●
Sound of drainage water through drain pipe
Cracking sound due to temperature changes of parts
Indoor odor components, cigarette odor and cosmetic odor accumurated
in the air conditioner and its air is discharged.
Unit inside is dusty. Consult your dealer.
Indoor moisture is cooled by cool wind and accumulated by dewdrop.
●
Cleaning is necessary because unit inside (heat exchanger) is dirty.
Consult your dealer as technical engineering is required.
●
During defrost operation
●
Fan rotating makes operation smoothly.
●
Fan may sometimes rotates because of drying heat exchanger due to
settings.
●
When air discharge temperature is low or during defrost operation,
horizontal wind flow is made automatically.
●
Flap position is occasionally set up individually.
When wind-direction is changed, flap operates after searching for
standard position.
Dust accumulation inside indoor unit is discharged.
This is for operation check in order to confirm whether the fan motor
rotation is within use range.
