2)  Stoppage due to electric troubles
a)  Thermostat   is out of control
Analysis of Trouble
In case the thermostat does not work in its good order or its

temperature sensor has not been installed properly, frequent stoppage is
also likely to occur.

Remedy
Try to adjust the temperature sensor’s position until the compressor can

be started and stopped normally. If this cannot be achieved, and the
stoppage still occurs repeatedly, it is most likely that the mechanical parts
or contacts are out of order, disassemble the thermostat, make a thorough
checkup and repair it.

b)  Overload of electric motor
Analysis of Trouble
Probably, too many things have been put into the refrigerator, and

hence the thermal load exceeds its refrigerating capacity ; or in case the
power supply voltage drops considerably, the current flowing through the
motor will increase drastically making the thermal protector actuate and the
fuse blown , and hence the motor stops running. If the motor is still running
continuously in such a case , its windings will be burned out .

Remedy
Reduce the thermal load, pay attention to the variation in voltage of the

power supply.

c)  Abnormal thermal protection
Analysis of Trouble
The compressor current is within its normal range, but the thermal

protector actuates repeatedly.

Remedy
Replace the thermal protector with a new one.
3) Sudden stoppage due to other causes
Normal Stoppage
Start and stop of the compressor is generally controlled by a thermostat .

When the temperature in the refrigerator reaches its desired value, the
thermostat will shut down the compressor automatically. Never take this
normal operation as a trouble, care should be taken to differentiate it from
other real troubles in servicing.

D. Compressor won 't start
In case the compressor cannot be started, you must find out the origins

of this trouble through checkup step by step, because probably there are
many causes, including those electrical and mechanical.

1) Inspect the power supply to see whether it is connected to the
