8-3 Troubleshooting for Normal Malfunction
26 The Foremost Inspecting Items
①
The input voltage must be 10% tolerance of the rated Voltage. If it is not
the case, the air-conditioner will probably not work normally.
②
Check 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.
③
If the following phenomena are found, the problem is not from the air-conditioner
itself.
NO. Problems Causes
1
The motor is heard operating but
the air-conditioner does 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 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 motor speed to what you set.
3
The compressor works
discontinuously at dehumidifying
mode. The air-conditioner will automatically
control the working of the compressor
according to the inside temperature.
4
The air-conditioner does not work
while the LED display is on.
The TIMER is set with the A/C; it will
be in hold on condition. If the TIMER
setting is cancelled, the air-conditioner
will return to normal working condition.
5
The compressor works
discontinuously at cooling and
dehumidifying mode, and the
indoor motor slows down.
The compressor stops Indoor Unit or the
motor slows down to prevent the indoor
heat exchanger from being frozen.
