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, fluorescent 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 filter may be dirty.
Remove any source of odours in the vicinity of both the indoor
or outdoor units. Check and clean the dust filter 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 flowing 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 flowing liquid. No action is required.
