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.
Troubleshooting
The unit changes from
COOL/HEAT mode to
FAN mode
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.

If ANY of the following conditions occurs, turn off your unit immediately!
•
The power cord is damaged or abnormally warm
•
You smell a burning odor
•
The unit emits loud or abnormal sounds
•
A power fuse blows or the circuit breaker frequently trips
