Problem
Solution
Cool air does not
come out of the
air conditioner.
• Check whether the set temperature is
higher in the Cool mode than the current
temperature. Press the Temperature button
on the remote control to change the set
temperature.
• Check whether the air filter is blocked with
dirt. If the air filter is blocked, the cooling
performance may decrease. Remove dirt
regularly.
• Check whether the outdoor unit is covered
or installed near obstacles. Remove the
coverings and obstacles.
• Check whether doors or windows are open.
This may cause poor cooling performance.
Close the doors and windows.
• Check whether the air conditioner is turned
on immediately after the cooling 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 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.
