Possible causes
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 defrost cycle is activated
in order to defrost the unit.
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.
In humid regions, a large temperature difference between the
room's air and the conditioned air can cause white mist.
When the unit restarts in HEAT mode after defrosting, white
mist may be emitted due to moisture generated from the
defrosting process.
A squeaking sound is heard when the system is OFF or in
COOL mode. The noise is also heard when the drain pump 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.
