COMMON ISSUES
The following problems are not a malfunction and in most situations will not require repairs.
Issue 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.
The unit changes
from COOL/HEAT
mode to FAN
mode
The unit may change its setting to prevent frost
from forming on the unit. Once the temperature
increases, the unit will start operating in the
previously selected mode again.
The set temperature has been reached, at which
point the unit turns off the compressor. The unit will
continue 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 rushing air sound may occur when the louver
resets its position.
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
Low hissing sound during operation: This is normal
and is caused by refrigerant gas flowing through
both indoor and outdoor units.
Low hissing sound 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.
Squeaking sound: Normal expansion and contraction
of plastic and metal parts caused by temperature
changes during operation can cause squeaking
noises.
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 nonuse, 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 furniture, 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.
Operation
is erratic,
unpredictable, or
unit is
unresponsive
Interference from cell phone towers and remote
boosters may cause the unit to malfunction. In this
case, try the following:
• Disconnect the power, then reconnect.
• Press ON/OFF button on remote control to
restart operation.
SAFETY
PRECAUTIONS
If ANY of the following
conditions occurs, turn off
your unit immediately!
• You smell a burning odor
• The unit emits loud or
abnormal sounds
• A power fuse blows or the
circuit breaker frequently
trips
• Water or other objects fall
into or out of the unit
