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.
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.
