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.

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 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.

Possible Issues

The following symptoms are not a malfunction and in most situations will not require repairs.
