Symptom Cause
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 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 filters have become moldy and should be cleaned.
