• 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.
• 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.)
• 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.
