Maintenance Service and Trouble Shooting

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 compressor circuit.

Analysis of Trouble

In case the compressor cannot be started, this will generally exhibit in the power supply circuit, for instance, power failure, poor contact of switch, and blown fuse. Make a comprehensive analysis of these phenomena, fine out its real cause and take correct measures to remove this trouble.
