Moisture on air
outlet : If the unit operates
at high humidity for a long time, moisture will be generated on the air outlet
grill and then drip off.
Noise from
indoor unit: The noise emitted
when the fan or compressor relay is switching on or off./When the defrosting

Air Conditioner Name of Parts
Troubleshooting
The air conditioner is
not user serviceable.Incorrect repair may cause electric shock or fire so
please contact an authorized service center for professional repair. Following
checks prior to contact may save your time and money.
Phenomenon: The unit
does not operate
Troubleshooting: The
unit does not operate if it is turned on immediately after it is turned off.
This is to protect the unit. You should wait about 3 minutes.
Phenomenon: Odours are
emitted
Troubleshooting:
- Some
odours may be emitted from the indoor unit. This is the result of room
smells (such as furniture,tobacco,ect.) which have been taken into the air
conditioner.
- Consult authorized service center for cleaning
if the odours still exist.
Phenomenon: Water
flowing” noise
Troubleshooting: The
swishing noise like water flowing is the refrigerant flowing inside the unit.
Phenomenon: Mist is
emitted in COOL mode
Troubleshooting: During
cooling operation, a thin mist may be seen emitted from the indoor unit due to
high room temperature and humidity. After a period of time, the mist will
disappear with the decrease of room temperature and humidity.
Phenomenon: Cracking
noise
Troubleshooting: This
is the sound of friction caused by expansion and/or contraction of panel or
other parts due to the change of temperature
Phenomenon: The unit
can not be started up
Troubleshooting:
- Is the
power cut off?
- Is the
power plug loose? ( if applicable )
- Is the
circuit protection device tripped off?
- Is
voltage higher or lower? (Tested by professionals)
- Is the TIMER correctly used?
Phenomenon:
Cooling/Heating effect is poor
Troubleshooting:
- Is
temperature setting appropriate?
- Is the
inlet or outlet blocked?
- Is the
filter dirty?
- Is the
window or the door open?
- Is low
fan speed set?
- Are there heat sources in the room?
Phenomenon: Remote controller
is not available
Troubleshooting:
- Check
if there is magnetic or electrical interference near the unit that may
affecting operation of the controller. In this case, pull the plug out and
reinsert it.
- Is the remote controller within its operating
range or obstructed? Check the condition of the batteries and replace them
if necessary. Check if the remote controller is damaged.
Phenomenon: Water
leakage of indoor unit
Troubleshooting:
- The
humidity is high.
- Condensing
water overflows.
- Drain hose is loose.
Phenomenon: Water
leakage of outdoor unit
Troubleshooting:
- During
cooling operation, water condensate is generated around the pipes and
connection joints.
- During
defrosting operation,the thaw water flows out.
- During heating operation,the water on the heat
exchanger drips out
Phenomenon: Noise from
indoor unit.
Troubleshooting:
- The
noise emitted when the fan or compressor relay is switching on or off.
- When the defrosting operation is started or
stopped, there is a sound of refrigerant flowing in the reverse direction.
Phenomenon: Indoor unit
can not blow air
Troubleshooting:
- In HEAT
mode, when the temperature of indoor heat exchanger is very low, air flow
is stopped in order to prevent cold air. (Within 2 minutes)
- In HEAT
mode, when the outdoor temperature is low or humidity is high, frost will
be formed on the outdoor heat exchanger. The unit will defrost
automatically and indoor unit will stop blowing air for 3-12 minutes.
- During
defrosting operation, water or vapour may be emitted.
- In DRY mode, the indoor fan will stop blowing
air for 3-12 minutes in order to avoid condensing water being vaporised
again.
Phenomenon: Moisture on
air outlet
Troubleshooting: If the unit operates at high humidity
for a long time, moisture will be generated on the air outlet grill and then
drip off.
