Troubleshooting Guide
4.2
1. The Foremost Inspecting Items
⑴The input voltage must be within +10% tolerance of the rated Voltage. If it
is not the case, the air-conditioner will probably not work normally.
⑵Check the connecting cord between indoor unit and outdoor unit to see if
it is properly connected. The connecting must be done according to the
wiring diagram, please also notice that even different models may have the
connecting cord of the same specification.
Please check if the marks at the connecting terminal and the marks on the
cord can match, otherwise, the air-conditioner will not work normally.
⑶If the following phenomena are found, the problem is not from the
air-conditioner itself.
11

5
The compressor works
discontinuously at cooling and
dehumidifying mode, and the indoor
fan motor slows down.
The compressor stops internally or the fan
motor slows down to prevent the indoor heat
exchanger from being frozen.
NO. Problems Causes
1The motor is heard operating but the
air-conditioner dose not work when
the indoor unit is powered on
Since the air-conditioner is powered on, it
will come to working condition as long as you
press the ON/OFF button of the remote
control and the Signal is well received.
2
The compressor stops running but
the indoor fan motor keeps working
when it is at cooling mode with the
indoor temperature higher than set
temperature.
If you turn off the air-conditioner and restart it
immediately, it will return to normal in 3
minutes, after that, the air-conditioner will
automatically adjust the indoor fan speed to
what you set.
3The compressor works
discontinuously at dehumidifying
mode.
The air-conditioner will automatically control
the working of the compressor according to
the inside temperature
4The air-conditioner does not work
while the LED display is on.
The TIMER is set with the air-conditioner; it
will be in hold on condition. If the TIMER
setting is cancelled, the air-conditioner will
return to normal working condition

3. The Indoor Fan Motor Does Not Work
⑴Items
a) Check if the indoor fan motor is connected correctly to the connector (CN8)?
b) Check if the AC input voltage is correct?
c) Check if the IC of indoor fan motor is connected correctly to the connector
(CN2)?
d) Check if the capacity of indoor fan motor is connected correctly to the

5. The Step Motor Does Not Work
⑴Items
a) Check if the input voltage is correct?
b) Check if the step motor controlling the up-down movement firmly
connected to Cn2?
⑵Trouble shooting procedure
