TROUBLESHOOTING
PROBLEM POSSIBLE CAUSE
The appliance does not
start when pressing on/
off button
• The appliance has a protection feature that prevents it from being turned
back on for 3 minutes after being turned off to avoid overloading
• Room temperature is lower than the set temperature. (Cooling mode)
• Room temperature is higher than the set temperature (Heat mode)
• Power failure
• A fuse is burned out
• Remote control batteries have burned out
The appliance changes
from cool or heat to fan
mode automatically
• The appliance may change mode to prevent frost from forming on the
internal coils
• The set temperature has been reached, at which point the compressor
is turned off. The appliance will continue operating when the room
temperature fl uctuates from the set temperature
The indoor or outdoor
appliance are emitting
white mist
• In humid regions, a large temperature difference between the room
temperature and the set temperature can cause white mist
• When the appliance restarts in HEAT mode after defrosting, white mist
may be emitted due to moisture generated from the defrosting process
The indoor or outdoor
appliance are making
noise
• A rushing air sound may occur when the louver resets its position
• A squeaking sound may occur after running the appliance in HEAT
mode due to the expansion and contraction of internal plastic parts
• A low hissing sound during operation is normal; this is caused by
refrigerant gas fl owing through the appliance
Dust is emitted from the
appliance
• The appliance may accumulate dust on the internal components during
long periods of non-use, which will be emitted when the appliance is
turned on
The appliance emits a bad
odor
• The appliance may absorb odors from the surrounding environment,
(cooking smells, animal smells, cigarette smells, etc.) which will be
emitted during operation
• The fi lter has become clogged and should be cleaned
The fan of the outdoor
appliance does not
operate
• During operation, the fan speed on the outdoor appliance is controlled
to optimize product effi ciency
Operation is erratic,
unpredictable, or
appliance is unresponsive
• Interference from cell phone towers and remote boosters may cause the
appliance to malfunction. To reset the appliance: disconnect the power
then reconnect and press the power button to restart operation
Poor cooling or heating
performance
• Temperature setting is higher or lower than the ambient room
temperature
• The outdoor temperature is extremely high or low
• The air fi lter is clogged
• The air inlet or outlet is blocked
• Doors and windows are open
• Low refrigerant due to leak or long-term use
• The heat exchanger is dirty
The appliance starts and
stops frequently
• There is too much or too little refrigerant in the system
• Incompressible gas or moisture has entered the system
• The voltage is too high or too low
• The compressor is malfunctioning
