III. Troubleshooting

Types of pressure deviation

Possible causes

Method for troubleshooting

1.

The pressure at the high pressure side

remains unchanged or just slightly rises

(compared with the value when the

engine stalls); the pressure at the low

pressure side is within or under the

range as shown; the air conditioner is

under refrigeration.

2.

The pressure at the high pressure side is

normal; the pressure at the low pressure

side is within the range as shown; the

air conditioner is under refrigeration.

Lack of refrigerant or

the expansion valve

fails

Evacuate the refrigerant

● If the volume of the refrigerant is normal

1.

Replace the expansion valve

2.

Refill the refrigerant to the system

3.

Test the pressure again

● If the volume of the refrigerant is short

1.

Check if there is leaking, if there is

fix it

2.

Refill the refrigerant to the system

3.

Test the pressure again

The pressure at the high pressure side is

higher than the specified value; the pressure

at the low pressure side falls rapidly to within

or under the range as shown; the air

conditioner is under refrigeration.

The blockage or

throttling occur

somewhere in the

refrigerant pipelines

The expansion valve

fails

Touch the pipelines to feel the temperature

change

● If there exists temperature differences on

several parts of a certain component

1. Utilize the compressed air and nitrogen

gas to dredge the pipeline and replace the

expansion valve

2. Replace the parts blocked

● If no trouble found

1.

Dredge the pipelines with compressed

air and nitrogen

2. Test the pressure again

Initially, the pressures at the high and low

pressure sides are normal, but after a period

of time, the pressure at the high pressure side

is higher than the specified value and the

pressure at the low pressure side is within or

The expansion valve

fails

There exists vapor in

the refrigerant pipelines

Check for dirt or rust in the expansion valve

and replace it when necessary

● Dredge the pipelines with compressed

air and nitrogen

79

under the range as shown; the air conditioner

is under refrigeration.

The pressure at the high pressure side is

higher than the specified value or is too high;

the pressure at the low pressure side is too

high; the air conditioner is under

refrigeration; the compressor makes

exceptional sounds (especially when just

starts the engine).

The refrigerant in the

refrigerant pipelines is

excessive

The expansion valve

fails or the compressor

is disabled

Evacuate the refrigerant

● If the volume of the refrigerant is normal

1.

Replace the expansion valve

2.

Refill the refrigerant to the system

3.

Test the pressure again

● If the refrigerant is obviously excessive

1. Refill the coolant into the system

2．Test the pressure again

Note: If the system is still off normal after

retesting the pressure, install the expansion

valve replaced again and dredge the

pipelines with compressed air and nitrogen,

and then further replace the compressor and

the fluid reservoir and drying chamber.

When turning off the engine, the pressure at

the high pressure side slightly rises while the

pressure at the low pressure side slightly

falls;

the

air

conditioner

is

under

refrigeration.

The

compressor

is

disabled

Dredge the pipelines with compressed air

and nitrogen

Replace the compressor and the fluid

reservoir and drying chamber

High pressure side is correct, low pressure

side is too low, AC refrigerating correct,

sometimes the evaporator has ice(even the

refrigerant quantity is correct)

The expansion valve

fails or the compressor

is disabled

Replace the expansion valve

Note: If the system is still off normal after

retesting the pressure, install the expansion

valve replaced again and dredge the

pipelines with compressed air and nitrogen,

and then further replace the compressor and

the fluid reservoir and drying chamber.

1.

High/low pressure sides are correct, AC

refrigerating deficiency.

2. High/low pressure sides are correct, the

sound of compressor is abnormal (especially

when the engine is started), AC refrigerating

good

The transmission oil in

the air conditioner

pipelines is excessive

Evacuate the refrigerant

● Dredge the pipelines with compressed

air and nitrogen

Note: Adjust the volume of the lubricant

when replacing such component of the air

conditioner system as the compressor

The reservoir can not be used

• Perforated

• The sealed position is

damaged

• Thread of fasten part

is damaged, outside air

entering to system

Replace it
