Refer to the following chart if the air conditioner operates abnormally. This may save 

time and unnecessary expenses.

•  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.

•   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.

•   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.
