Common Issues
The following problems are not a malfunction and in most situations will not require repairs.

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 can be emitted during operation.
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.
