TROUBLESHOOTING
Before calling your dealer, refer to the checklist
Problem?
• The unit does not operate
• The unit does not cool or heat effectively
•The unit does not receive remote control signals, or the remote control display is weak or
Problem?
• Air is not discharged immediately
• Operation stops suddenly
• Fog is blowing out from the unit
• There is a noise
• The outdoor unit gives off water and steam
Check
•Has a circuit breaker been tripped or a fuse blown?
•Is the power supply plug disconnected from the outlet?
•Is the Timer being used correctly?
•Has the temperature been set correctly?
•Are the air filters dirty?
•Are the air intake or outlet vents blocked?
•Are all the windows and doors closed?
∗Measure the temperature difference. Operation is normal if, 15 minutes after the start of operation, the temperature difference between the air intake and outlet vents is 8°C or above for cooling and 14°C or above for heating.
•Are the batteries weak?
•Have the batteries been inserted with the ε and ρ poles in the correct position?
Reason
•At Cooling • Soft Dry (auto Fan Speed)
Air will not be discharged for approximately 40 seconds. The unit is designed to prevent tobacco, cooking and body odors from being discharged together with the cool air.
•At Heating (POWER LED blinks)
This is to prevent cold air from blowing out. Please wait.
•At Cooling • Soft Dry (auto Fan Speed)
The indoor fan repeatedly stops for 80 seconds and operates for 20 seconds to check the indoor temperature. Whenever the temperature reaches the setting temperature, operation starts again.
•At Heating (POWER LED blinks)
When the outdoor temperature is low and humidity is high, frost accumulates on the outdoor unit. The POWER LED blinks when the unit is melting the frost. (Please wait as defrosting may take up to 10 minutes.)
•This occurs when the airflow from the air conditioner cools the room.
•A ‘passt’ sound is heard during defrosting or when the air conditioner operation has been stopped. This is caused by the refrigerant inside the air conditioner flowing in the opposite direction.
•The air conditioner will expand or contract due to changes in temperature, causing a cracking sound.
•The sound of water flowing is caused by the refrigerant flowing inside the unit.
•When defrosting, the frost melts and changes to water and steam.
■Call the Dealer Immediately
If the following conditions occur, turn off and unplug the main power supply, and then call the dealer immediately.
•Abnormal noise is heard during operation.
•Water or foreign material gets into the remote control by mistake.
•Water leak from the indoor unit.
•Switches or buttons do not operate properly.
•Circuit breaker trips or fuse blows frequently.
•Power supply cord and plug become unusually warm.
•A smell of burning is emitted.
■When the Timer LED at indoor unit blinks
The Timer LED blinks indicating abnormality.
Press the check button at remote control for 5 seconds, error code will be displayed.
