in the system, you have to open the tubing, re-evacuate it and then charge it with
refrigerant.
Stoppage due to electrical troubles
Thermostat is out of control due to electric troubles
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.
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.
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.
Sudden stoppage due to other causes.
Normal Stoppage
Thermostat generally controls start and stop of the compressor. 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 problem; care should be taken to
differentiate it from other real problems in servicing.
Compressor won 't start.
