Problem Solution
Cool or warm air
does not come
out of the air
conditioner.
• Check whether the air conditioner is running the
defrost function. When ice forms in winter or the
outdoor temperature is too low, the air conditioner
runs the defrost function automatically. While this
function is running, the indoor fan stops and warm
air does not come out.
• Check whether doors or windows are open. This
may cause poor cooling or heating performance.
Close the doors and windows.
• Check whether the air conditioner is turned on
immediately after the cooling or heating operation
stops. In this case, only the fan runs to protect the
outdoor unit compressor.
• Check whether the pipe length is too long. When
the pipe length exceeds the maximum pipe length,
the cooling and heating performance may decrease.
I cannot change
the air flow
direction.
• Check whether the good'sleep function is running.
While this function is running, you cannot control
the air flow direction. (But you can control the air
flow direction if this function is running in the Heat
mode.)
I cannot change
the fan speed.
• When the Auto, Dry, or Fast mode is running or
the good'sleep function is running in the Cool
mode, the air conditioner controls the fan speed
automatically and you cannot change the fan
speed.
