Troubleshooting
Do not repair the air conditioner yourself. Incorrect repairs may cause electric shock or fire, so please contact an
authorized service center for professional repair. You can save time and repair fees by going over the troubleshooting
tips below.
A creaking noise can be heard when the unit
starts or stops.
This is caused by the deformation of plastic due
to temperature changes.
Air conditioner does not operate at all.
• Has the power been turned off ?
• Is the leakage protection switch working?
• Is the voltage higher or lower?
• Is TIMER ON function activated?
• Is the wiring loose?
• Is the SET TEMP. suitable?
• Is the air inlet or outlet obstructed?
• Are the air filters dirty?
• Are the windows and doors closed?
• Is the indoor fan speed set at low speed?
• Is there any other heat source in your room?
• The remote control may occasionally stop
working when the air conditioner's functions
are changed too frequently. Remove the
power plug and insert it again to restart the
appliance.
• Is the remote control out of the range of the
indoor unit? Are there any obstructions
between the remote control and the signal
receptor?
• Replace the worn batteries in the remote
control if the voltage of the batteries is not
sufficient.
