Troubleshooting
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 o.
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 o the
compressor. The unit will continue operating when the temperature
fluctuates again.
The indoor unit
emits white mist
In humid regions, a large temperature dierence 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 mode to
FAN mode
The indoor unit makes
noises 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.
SAFETY PRECAUTIONS
If any of the following conditions occurs, turn o 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
•Water or other objects fall into or out of the unit
DO NOT ATTEMPT TO FIX THESE YOURSELF! CONTACT AN AUTHORIZED
SERVICE PROVIDER IMMEDIATELY!
Cooling and Heating Models: If the Operation light and PRE-DEF (Pre-heating/
Defrost) indicators are lit up, or the Operation light is lit up and the LCD screen
display “dF”, the outdoor temperature is too cold and the unit’s anti-cold wind
is activated in order to defrost the unit.
A squeaking sound is heard when the system is OFF or in COOL mode. The
noise is also heard when the drain pump (optional) is in operation.
