TROUBLESHOOTING
Refer to the following chart if the air conditioner operates abnormally. This may save time and unnecessary
expenses.
PROBLEM SOLUTION
The air conditioner
does not start operating
immediately after it has
been restarted.
• Because of the protective mechanism, the appliance does not start
operating immediately to keep the unit from overloading. The air
conditioner will start in 3 minutes.
The air conditioner does
not work at all.
• Check that the power plug is properly connected. Insert the power plug
into the wall socket correctly.
• Check if the circuit breaker is switched off.
• Check if there is a power failure.
The cool air does not
come out of the air
conditioner.
• Check if the set temperature is higher than the current temperature. Turn
the Thermostat knob clockwise to change the set temperature.
• Check if the air filter is block by dirt. Clean the air filter every two weeks.
• Check if the air conditioner has just been turned on. If so, wait 3 minutes.
Odors permeate in the
room during operation.
• Check if the appliance is running in a smoky area or if there is a smell
entering from outside. Operate the air conditioner in Fan mode or open
the windows to air out the room.
The air conditioner
makes a bubbling sound.
• A bubbling sound may be heard when the refrigerant is circulating through
the compressor. Let the air conditioner operate in a selected mode.
The air conditioner
vibrates excessively
or makes a lot of noise
during operation.
• Check if there is a gap between the air conditioner and the wall. Insulate
the crack securely.
Water is dripping from
the air flow blades.
• Check if the air conditioner has been cooling for an extended period of
time with the air flow blades pointed downwards. Condensation may
generate due to the difference in temerpature. Push the vertical air flow
blade upward and run the appliance.
