5.1 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 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.
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 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 & contraction of the unit’s plastic parts.
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.
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 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.
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
