Problem Possible Causes
Unit does not
turn on when
pressing ON/
OFF button
The unit has a 3-minute protection feature that prevents the unit from
overloading. The unit cannot be restarted within three minutes of being
turned off.
Cooling and Heating Models: If the Operation light and PRE-DEF (Pre-heating/
Defrost) indicators are lit up, the outdoor temperature is too cold and the unit’s
anti-cold wind is activated in order to defrost the unit.
In Cooling-only Models: If the “Fan Only” indicator is lit up, the outdoor
temperature is too cold and the unit’s anti-freeze protection is activated in
order to defrost the unit.
The unit changes
from COOL mode
to FAN mode
The unit changes its setting to prevent frost from forming on the unit. Once
the temperature increases, the unit will start operating again.
The set temperature has been reached, at which point the unit turns off the
compressor. The unit will resume operating when the temperature fluctuates
again.
The indoor unit
emits white mist
In humid regions, a large temperature difference between the room’s air and
the conditioned air can cause white mist.
Both the indoor
and outdoor units
emit white mist
When the unit restarts in HEAT mode after defrosting, white mist may be
emitted due to moisture generated from the defrosting process.
The indoor unit
makes noises
A squeaking sound is heard when the system is OFF or in COOL mode. The
noise is also heard when the drain pump (optional) is in operation.
A squeaking sound may occur after running the unit in HEAT mode due to
expansion and contraction of the unit’s plastic parts.
Both the indoor
unit and outdoor
unit make noises
A low hissing sound may occur during operation. This is normal and is caused
by refrigerant gas flowing through both the indoor and outdoor units.
A low hissing sound may be heard when the system starts, has just stopped
running or is defrosting. This noise is normal and is caused by the refrigerant
gas stopping or changing direction.
The outdoor unit
makes noises The unit will make different sounds based on its current operating mode.
Dust is emitted from
either the indoor or
outdoor unit
The unit may accumulate dust during extended periods of non-use, which
will be emitted when the unit is turned on. This can be mitigated by covering
the unit during long periods of inactivity.
The unit emits a
bad odor
The unit may absorb odors from the environment (such as furnitur
e, cooking,
cigarettes, etc.) which will be emitted during operations.
The unit’s filters have become moldy and should be cleaned.
The fan of the
outdoor unit
does not operate
During operation, the fan speed is controlled to optimize product operation.

Problem Possible Causes Solution
The unit
is not
working
Power failure Wait for the power to be restored
The power switch is offTurn on the power
The fuse is burned out Replace the fuse
Remote control batteries are dead Replace the remote control batteries
The unit’s 3-minute protection has
been activated Wait three minutes after restarting the unit
Poor cooling
performance
Temperature setting may be higher
than the ambient room temperature Lower the temperature setting
The heat exchanger on the indoor
or outdoor unit is dirty Clean the affected heat exchanger
The air filter is dirty Remove the filter and clean it according
to instructions
The air inlet or outlet of either unit
is blocked
Turn the unit off, remove the obstruction
and turn it back on
Doors and windows are open Make sure that all doors and windows are
closed while operating the unit
Excessive heat is generated by
sunlight
Close windows and curtains during
periods of high heat or bright sunshine
Low refrigerant due to leak or
long-term use Check for leaks, re-seal if necessary and
top off refrigerant
The unit
starts and
stops
frequently
There’s too much or too little
refrigerant in the system
Check for leaks and recharge the system
with refrigerant
There is air, incompressible gas or
foreign material in the refrigeration
system
Evacuate and recharge the system with
refrigerant
System circuit is blocked Determine which circuit is blocked and r
eplace
the malfunctioning piece of equipment
The compressor is broken Replace the compressor
Poor heating
performance
The outdoor temperature is lower
than 7°C/44.5°F
Check for leaks and recharge the system
with refrigerant
Cold air is entering through doors
and windows Make sure that all doors and windows are
closed during use
Low refrigerant due to leak or
long-term use
Check for leaks, re-seal if necessary and
top off refrigerant
