Troubleshooting
CAUTIONS
If one of the following conditions occurs, switch o the power supply immediately and
contact your dealer for further assistance.
•The operation light continues to ash rapidly after the unit has been restarted.
•The remote control buttons do not work.
•The unit continually trips fuses or circuit breakers.
•A foreign object or water enters the air conditioner.
•Other abnormal situations.
Common Problems
The following symptoms are not a malfunction and in most situations will not require repairs.
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 o.
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 o the
compressor. The unit will resume operating when the temperature fluctuates
again.
The indoor unit
emits white mist In humid regions, a large temperature dierence 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.
Troubleshooting 5
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 dierent sounds based on its current operating mode.
Problem Possible Causes
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 furniture, cooking,
cigarettes, etc.) which will be emitted during operations.
The unit’s lters 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.
