Troubleshooting
If the air conditioner operates abnormally, refer to the following chart to save time and unnecessary
expenses.
Problem
Solution
The air conditioner does not
work at all.
•
Check the power status, then operate the air conditioner again.
•
Switch on the circuit breaker, plug in the power cord, then operate the air conditioner
again.
•
Make sure that the isolator is turned on.
•
Check whether the Timed off function is running. Operate the air conditioner again by
pressing the Power button.
I cannot change the
temperature.
•
Check whether the Fan or Fast mode is running. In these modes, the air conditioner
controls the set temperature automatically, and you cannot change the set
temperature.
Cool or warm air does
not come out of the air
conditioner.
•
Check whether the set temperature is higher in the Cool mode or lower in the Heat
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
and heating performance may decrease. Remove dirt regularly.
•
Check whether the outdoor unit is covered or installed near obstacles. Remove the
coverings and obstacles.
•
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.
The remote control does not
work.
•
Replace the batteries in the remote control with new ones.
•
Make sure that nothing is blocking the remote control sensor.
•
Check whether there are strong lighting apparatus near the air conditioner. Strong light
which comes from fluorescent bulbs or neon signs may interrupt the electric waves.
The Timed on/off function
does not work.
•
Check whether you pressed the SET button on the remote control after setting the
time.
The indicator blinks
continuously.
•
Press the Power button to turn off the air conditioner or disconnect the power plug. If
the indicator is still blinking, contact the service centre.
Odours permeate in the room
during operation.
•
Check whether the air conditioner is running in a smoky area. Ventilate the room or
operate the air conditioner in the Fan mode for 3 to 4 hours. (There are no components
used in the air conditioner that emit a strong odour.)
•
Check whether the drains are clean. Clean them regularly.
