and cause the shaft to be seized. Copper plating may also result in seizing of shaft.

b) Seizing of piston This is caused by too small fit clearance between the piston and 

cylinder or expansion due to heat. Judgement of seizing shaft and piston: After the 

refrigerator has been powered on, the compressor will not start and run, but a slight 

hum sound can be heard, and several seconds later, thermal protective relay will actuate 

and make the contacts open; this process will occur repeatedly, but the compressor 

cannot be started.

E. Compressor won›t stop Sometimes, the compressor will run continuously(for several 

hours or run without end), If the food placed in the refrigerator is not too much, there 

may be the following two situations: i) the refrigerator very low, this means that the 

control system is probably out of order; ii) the control system works normally, and there 

are troubles in the refrigerating system or other parts.

1) Temperature is set improperly

a) The temperature control knob is set to the «coldest» position. This position is to be 

used for fast freezing or continuous running, its temperature for power off is too low, 

therefore, the compressor won›t stop and the temperature in the refrigerator becomes 

lower and lower.

b) Inspection method: check the temperature control knob to see whether it is set in 

the position «coldest».

2)  Thermostat  is  malfunctioning  and  makes  the  compressor  running  continuously 

Analysis  of  Trouble  When  the  thermostat  doesn›t  work  normally,  it  will  make  the 

compressor run continuously, and hence very low temperature will be achieved in the 

refrigerator. The fault is generally due to the fact that the contacts of the thermostat 

cannot be released. Remedy Dismantle the thermostat and make a through checkup, if 

it is totally out of functioning, replace it with a new one.

3)  evaporation  temperature  is  too  high  in  refrigerating  system,  resulting  in  lower 

refrigerating capacity and hence continuous running of compressor Analysis of Trouble 

Leakage  of  refrigerant  and  clogging  in  a  refrigerating  system  will  directly  affect  its 

refrigerating capacity. Due to the reduction in its refrigerating capacity, the refrigerator 

temperature  cannot  reach  its  rated  value,  the  thermostat  won›t  work,  thus  the 

compressor runs continuously. When the evaporation temperature in the system is too 

high, the temperature sensing agent in the temperature sensor is also hotter, therefore, 

sensing agent from the temperature sensor. Remedy Remove the relay cover to check 

up its contacts, if they are open, this means that the original setting is not properly set 

or temperature sensing agent has leaked out of the temperature sensor. Try to turn the 

adjusting stem of this value in the direction of the lower temperature graduation, then 

check the contacts to see whether they are closed. If they are still not closed, dismantle 

the temperature sensing disc and then immerse it into warm water to see whether 

the contacts actuate, if not, it can be preliminarily determine that temperature sensing 

agent has leaked out, and it must be replaced with a new thermostat.

4) Motor troubles and other electric faults

a)  Motor  windings  have  been  burned  or  short-circuited  between  turns  Analysis  of 

Trouble When motor windings have been burned or short-circuited between turns, the 

fuse will be blown repeatedly, and the blowout occurs particularly at the instant when 

you close the knife switch. Remedy Check the terminals and the outer casing to see 

whether they are short-circuited, and measure the resistance of each phase with an 

avometer. If short circuit occurs or the resistance of a certain phase is low, this means 

that short circuit does exist in the windings and/or between turns, and insulation layers 

have been burned or deteriorated. A megameter can be used in this inspection, too. I 

f the insulation resistance is lower than 2 MW, this means that the insulation layer is 

already breakdown. If the motor has been burned, repair it or replaced it with a new 

one.

b) Fault of control relay Analysis of Trouble Overheat, burnout or wear of control relay 

contacts may occur generally. All these will cause poor contact in electricity. Remedy 

Dismantle it to repair, or replace it with a new one.

c) Poor electric contactor in thermostat Analysis of Trouble Burnout of contactor and 

leakage of temperature sensing agent may occur generally. Remedy Replace the old 

with a new one.

d) Check the terminals for loose connection and electric circuits for other abnormal 

phenomena.

5) Mechanical faults of compressor

a) Seizing of shaft This phenomenon is caused mostly by poor lubrication, such ad 

insufficient  quantity  of  lubricant,  clogging  in  the  lubricant  oil  line,  or  intermittent 

lubricant oil supply. Dirt and other impurities in the lubricant oil will increase its viscosity
