The air conditioner
does not react after
it is powered ( after
the plug is inserted,

No power

Power plug is not well plugged in and poor con­nection

Fuse of controller burnt out

The transformer connection is loose or has bad
contact or the transformer has malfunction

Controller is broken

Measure insulation resistance to ground to see
if there is any leakage.

The circuit or the part of the air conditioner has
malfunction. They heat and break the insulation
and lead to short circuit or creepage. Measure
the insulation resistance or eliminate the malfunc­ tion one by one. If the breaker itself has

malfunction, then replace the breaker.

Check power supply circuit.

Check if the plug is properly plugged in and
make the loose contact firm.

Change controller fuse

Fasten the wiring; measure the output
voltage of the transformer, if it is
incorrect, change the transformer

Check remote controller

In cool, heat mode,the
outdoor
unit and compressor
will not run.

The remote controller

does not receive

signals (after it is

powered, the buzzer

will sound, unless it

has malfunction)

Power voltage is too low

creepage of parallel capacitor of relay loop,

relay is broken etc.)

Wire loose or wrong connection

Improper setting of temperature

Remote controller is short of power

Remote controller malfunction

Receiver loose or poor connection

Receiver is broken

Change batteries

First, press the manual switch button AUTO,
if there is no response,check based on the
above methods. If it runs normally after
pressing the button,check again whether the
installation position and the connection wire
of the reception head is correct. If it is
correct,then replace the receiver or the re-

mote controller.

to deal with the system.

Make sure that heat insulation for the thick and thin pipes
is good. Heat insulation must also be provided for the

Clean the dust accumulated on the surface of
the heat exchanger.

Properly install the rainproof plate or the sunproof plate. If the
maximum cool air still can not meet the requirement, it is sug­gested to replace the air conditioner.

Replace the capaci­tor

Replace the motor

Keep certain air tightness indoors, try not to use
electricalappliance with large quantity of heat

The fan does not
run when it is set
to supply air.

The indoor fan motor is burned or breaks
or has the heat protector malfunction.

The built-in heat protector of the motor
breaks frequently because the motor
is abnormal.

Wrong connection

Replace the fan motor or the defective part.

Replace the fan motor

Make the correction connection based on the

PG motor locked protection H6:

Probable reasons:

1. Air vents were blocked which may cause the fan speed is too slow;

2. Fan blade locked;

3. Motor locked;

4. Fan motor capacitor damaged;

5. Motor damaged (ordors, winding, open circuit or shortcircuit are not normal, when testing the winding, pls distinguish
whether the motor body cause temperature is too high so that bring on the thermal protector starts up)

6. IC board damaged (during normally running, there are voltage at both capacity input and output)

7. Mainboard damaged.

8. Motor thermal protection.

Disposal methods:

1. Remove the obstruction;

2. Reassembling;

3. Replace motor;

4. Replace capacitor;

5. Replace motor;

6. Replace circuit board;

7. Replace mainboard;

8.Under the normal circumstances, the motor will not act, but in other circumstances, such as evaporator is very dirty, to much dust
attached on the fan blade that will cause the motor overload running, so that during the operation, frequent thermal protection will
happen, so it is need to be cleaned or replaced.
