- Page 15 Maintenance Service and Trouble Shooting 5 Normal Phenomena—Not Troubles for Refrigerators In a domestic refrigerator, there is not only a complicated electric control system, but also a refrigerating system that is difficult to discern whether it is in a good working condition.
- Page 16 Maintenance Service and Trouble Shooting 6 Common Troubles in Refrigerators and Their Remedies Causes for troubles occurring in refrigerators are closely related to the quality of components and workmanship in assembling by manufacturers as whether refrigerators are properly used and maintained .The parameters generally used to express the working conditions of a refrigerator include the temperature inside the refrigerator ,operation rate ,electric power consumption ,noise level ,and other functional indexes .If any one of these parameters is beyond its permissible range ,this indicates that there is a fault or...
- Page 17 spring inside the compressor has broken . During the normal operation of compressor ,a slight and uniform hum sound due to undulation of electric current can be heard generally ,this is a normal phenomenon .However ,if it sounds like "tong ,tong ",i.e., an impact sound inside the compressor ,this means that a large quantity of wet vapour of refrigerant or refrigerating oil has come into the compressor cylinder ;if it sounds like "dang ,dang", a striking sound of metal parts inside the compressor ,this means that some moving parts have loosened...
- Page 18 make a hasty conclusion based on only one abnormal phenomenon .It is advisable to find out two or more abnormal phenomenon ,or conduct troubleshooting comprehensively with the aid of instruments or other ways ,because several kinds of troubles may share a common abnormal phenomenon ,and two or more abnormal phenomena may occur simultaneously due to a certain trouble .With this method ,you can reject some suspicious troubles and finally make a correct judgment .
- Page 19 b) In case excessive refrigerant has been charged, the liquid refrigerant that cannot evaporates in the evaporator will return to the compressor ,and thus a phenomenon of "liquid striking" will occur .The liquid refrigerant evaporates and effervesces as soon as it flows into the refrigerating oil at the bottom of compressor .If the condition is severe ,foams will fill all over inside the compressor housing and be sucked by the piston ,causing damage to the components of compressor .
- Page 20 Turn the refrigerator off ,and make preparations for defrosting ,open the refrigerator door to let the air come in ,or use a fan to speed up air flowing so as to shorten the time needed for defrosting .Never strike the frost layer with any iron tools or wood stick in order to avoid damage to the evaporator tubing .
- Page 21 quite a long time ,we find the leakage of refrigerant ,or in the course of its operation ,we have found that the refrigerator is gradually becoming not so cold and finally no refrigerating cab be achieved ; ii) fast leakage in that case ,all the refrigerant will escape swiftly due to abrupt rupture of system tubing .
- Page 22 dirt exhibits the same symptoms as that with ice, namely, higher gas suction pressure, lower temperature of discharged gas, and no gas flowing sound from the evaporator. The difference between the both is as follows: if the clogging is caused by dirt , tapping the suspicious clogged point (generally in the capillary or the connection joint of the filter) may cause the refrigerant to flow through partially, resulting in some corresponding change, whereas in that case if you heat it with a hot towel, no reaction will happen, no flowing...
- Page 23 1) Stoppage due to excessively high gas discharge pressure A) Too much refrigerant charged into the system Analysis of Trouble The phenomenon, such as loose frosting and poor refrigerating effect, may occur if excessive refrigerant has been charged into the system. Superfluous refrigerant will occupy a certain space of the evaporator, thus reduce its heat dissipating area, and the phenomenon of "liquid striking"...
- Page 24 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 .
- Page 25 Remedy Measure the voltage with a voltmeter, if it is really too low, give directions to the user for buying a stabilizer so as to step up the voltage, thus normal operation can be achieved. 3) Check the thermal relay to see whether its contacts are closed. Analysis of Trouble The contacts of thermal relay sometimes may be open due to the leakage of temperature sensing agent from the temperature sensor.
- Page 26 lubricant, clogging in the lubricant oil line, or intermittent lubricant oil supply. Dirt and other impurities in the lubricant oil will increase its viscosity 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.
- Page 27 4) No stoppage of compressor due to damaged heat-insulation layer inside case body and/or door seal Analysis of Trouble When the heat-insulation layer inside the case body deteriorates or the door seal is not closely touches the door frame, the temperature in the refrigerator will rise and makes the compressor running continuously.
- Page 28 If the leveling screws on refrigerator legs have not been adjusted properly ,vibration and noise will still occur even if the refrigerator has been placed on a level ground . 2) Abnormal noise from compressor Three suspended spring inside the compressor case are out of balance ,and strike against the case ,moreover ,the wear of compressor parts may cause noise sometimes .
