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

periods of non-use, which will be emitted when the appliance is turned on

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
