Troubleshooting
Refer to the following chart if the air conditioner operates abnormally. This may save time and unnecessary expenses.
PROBLEM SOLUTION
The air conditioner does
not work at all.
• Check power status and then operate the air conditioner again.
• Plug in or switch on the circuit breaker and then operate the air conditioner again.
• Check if you have set the Off Timer. Operate the air conditioner again by pressing the
Power button.
The temperature
adjustment is not working.
• Check if you have selected Dry/Fan/Turbo/d'light Cool mode. In these modes, desired
temperature is set to auto and you cannot adjust the temperature.
Cool/Warm air does
not come out of the air
conditioner.
• Check if the set temperature is higher(during Cool mode)/lower(during Heat mode) than
the current temperature. Press the Temp hr. + or – button on the remote controller to
change the set temperature.
• Check if the Full HD filter is blocked by dirt. If there is a lot of dust on the Full HD filter,
cooling(heating) performance may decrease. Clean them frequently.
• Check if the outdoor unit is covered or installed near the obstacle. Take the cover off and
take the obstacle away.
• If you want to operate the air conditioner in the sunlight, cover the outdoor unit using
curtains or etc.
• Check if the air conditioner is operating in De-ice mode.
When the ice formed in winter or the outdoor temperature is too low, the air conditioner
operates in De-ice mode automatically. In De-ice mode, indoor fan stops and cool air does
not come out.
• If the doors or windows are open, it may cause bad cooling (heating) performance.
Close the doors and windows.
• Check if the air conditioner has just been turned on after stopping cooling or heating
operation. In this case, just a fan will run to protect the outdoor unit compressor.
• Check if the pipe length is too long. When the pipe length exceeds maximum allowable
pipe length, cooling (heating) performance may decrease.

mode. In these modes, and you cannot adjust the

• Check that there are strong lighting apparatus near the air conditioner. Strong light which
comes from fluorescent bulbs or neon signs may interrupt the electric waves.
