SITUATION POSSIBLE CAUSES SOLUTIONS
The indoor unit does not 
appear to be operating.
There may have been a power outage. If there is a power outage and the electricity is not yet restored, 
wait for the power to be restored. When it is, the unit may need 
to be restarted.
The power cord plug may have become loose 
from the outlet.
Firmly push the plug into the power outlet.
A  circuit  breaker  may  have  been  tripped  or  a 
fuse may have blown.
Replace the fuse or reset the circuit breaker. Make sure that 
there are no other appliances on the same circuit.
There may be an active switch-on timer cur-
rently preventing operation.
If the timer setting was not intended, cancel it using the remote 
control, otherwise wait until the unit starts at the set time. 
The compressor 
does not appear to be 
operating.
The unit may have been immediately restarted 
after  having  being  shut  off,  or  the  operation 
mode may have been recently changed.
When changing operation modes or when immediately turning 
on the unit after having turned it off, a 3-minute protection delay 
is be triggered to protect the compressor. Wait until the delay 
has elapsed.
The indoor unit 
appears to be operating 
abnormally.
There may be interference in the room from a 
television, uorescent lamp, a wireless device, 
etc.
Disconnect and reconnect the power to the unit, then restart 
the appliance. 
The indoor unit emits 
undesirable odours.
Odours may be caught by the indoor or outdoor 
unit and blown into the room with the air, or the 
dust lters may be dirty.
Remove any source of odours in the vicinity of both the indoor 
or outdoor units. Check and clean the dust lters if necessary.
The indoor unit emits 
cracking sounds.
The indoor unit may have been recently turned 
on or off.
This is a normal phenomenon. The plastic components of the 
indoor unit  are  subject to thermal  expansion  and contraction 
caused by temperature changes. No action is required.
The indoor unit emits a 
sound of owing liquid.
The indoor unit may have been recently turned 
on or off.
This is a normal phenomenon. The refrigerant inside the indoor 
unit  is  moving  due  to  operation  starting  which  produces  the 
sound of owing liquid. No action is required.
The indoor unit emits a 
ne mist
The current ambient temperature and humidity 
levels in the room may be particularly high.
This is a normal phenomenon. Fog can appear when the cold, 
dry air blown by the indoor unit comes in contact with the warm, 
moist air near the air outlet. No action is required. The mist will 
disappear as the room gradually cools.
