Possible Causes
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.
In humid regions, a large temperature difference between the
room's air and the conditioned air can cause white mist.
When the unit restarts in HEAT mode after defrosting, white
mist may be emitted due to moisture generated from the
defrosting process.
Possible Causes
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.
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.
