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-

t ion one by one. I f the breaker i tself has

malfunction, then replace the breaker.

The transformer connection is loose or has bad

contact or the transformer has malfunction

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.

Heat insulation for the connection

pipes of the indoor unit and the out-

door unit is bad.

Make sure that heat insulation for the thick and thin pipes

is good. Heat insulation must also be provided for the

joint andthe exposed part of the copper pipe .

The installation position of the

outdoor unit is not appropriate.Good ventilation must be provided for the

installation position of the outdoor unit.

The outdoor temperature is too high. Properly install the rainproof plate or the sunproof plate. If the

maximum cool air still can not meet the requirement, it is sug-

gested to replace the air conditioner.

Keep certain air tightness indoors, try not to use

electricalappliance with large quantity of heat

The air tightness is not enough. People

come in and out too frequently. There

are heating devices indoors.

The indoor fan motor is burned or breaks

or has the heat protector malfunction.Replace the fan motor or the defective part.

The built-in heat protector of the motor

breaks frequently because the motor

is abnormal.

Replace the fan motor

Wrong connection Make the correction connection based on the

circuit drawing.

The fan does not

run when it is set

to supply air.

The fan capacitor has open circuit or is

damaged.Replace the fan capacitor of the same type

and same specification.

Replace the fan motorThe outdoor fan motor is damaged.

Wrong connection Make the correct connection based on the

circuit drawing

Replace the fan capacitor


The outdoor fan capacitor is damaged.

Malfunction of compressor

Breakage of running capacitor of

compressorReplace the capacitor

The voltage is too low or too high. Manostat is recommended.

Connect the circuit diagram correctlyWrong wire connection

The protector itself has malfunction.

Use the multimeter to check whether the con-

tact of the compressor is on when it is not

overheated. If it is not on, then replace the pro-

tector

The refrigerant is not enough or is too

much.Adjust the volume of the refrigerant

The capillary is blocked and the tem-

perature rises.Replace the capillary


Replace the protectorThe protector itself has malfunction.

The compressor does not run

smoothly or is stuck. The air dis-

charge valve is damaged

The compres-

sor is too hot

and leads to the

ac t ion o f the

protector.

The swing fan

does not run.

The torque of the swing motor is not

enough

Wrong connectionFirst, check whether the connection is

wrong. If no, replace the parts

The controller is damaged(IC2003 is

damaged, the swing relay can not

close, etc)

The compres-

sor is too hot

and leads to

the action of the

protector.
