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 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.

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.
