- Page 14 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. Both the systems are related and affect each other.
- Page 15 . Three Essentials for Checkup 1) Look Check the tubing of refrigerating system for cracks and various welding points for leaks ;if leakage occurs ,an oil stain can be seen...
- Page 16 Maintenance Service and Trouble Shooting Hums from a fully enclosed aggregate unit is the sound caused by overload indicating that the motor cannot be started normally ,meanwhile ,a clattering sound can be heard from inside the start relay ,which is produced because the start contacts cannot be released normally .A whistling sound is caused by the high pressure gas flowing out of the crack of the pressure tube inside the compressor ,and clucks are the sound of striking after the...
- Page 17 Maintenance Service and Trouble Shooting ambient temperature ,this means that most meshes of its screen has been clogged ,resulting in an obstructed flowing of refrigerant ,thus causing a drop in temperature due to throttling . d) Feel the temperature of exhaust gas from the refrigerating system .the exhaust gas should be very hot and this is the normal working state .For those refrigerator with enclosed type of compressor refrigerating system, no frost or dew drop will from on the gas suction...
- Page 18 Maintenance Service and Trouble Shooting many joints and sealed surfaces in a There are so refrigerator ,accordingly ,quite a lot potential leak points do exist in the system .In troubleshooting ,pay attention to those parts that are liable to leak ,check main connection points for oil seepage and tubing for cracks .If there is no severer leak point ,charge the system with nitrogen and detect leak points with the commonly adopted method ,repair them ,evacuate ,charge the system with refrigerant ,and then turn on the...
- Page 19 Maintenance Service and Trouble Shooting Analysis of Trouble Low efficiency of a refrigerating compressor refers to the actual reduction of gas discharge capacity ,and hence the corresponding reduction of refrigerating capacity ,under the condition that the refrigerant in the system is unchanged .This phenomenon occurs mostly when the compressor has been used for quite a long time ,its moving parts have worn to a considerable degree ,fit clearance between various parts have increased and sealing property of its gas valve has deteriorated ,resulting...
- Page 20 Maintenance Service and Trouble Shooting refrigerating effect is due to the accumulation of refrigerating oil left in the evaporator tubing in case no other troubles have been found . To clear off refrigerating oil left in the evaporator ,dismantle the evaporator ,purge it thoroughly and then dry it .In case it is difficult to dismantle it ,charge refrigerant from the evaporator inlet to wash it several times ,then purge and dry it with nitrogen .
- Page 21 Maintenance Service and Trouble Shooting heard ,and no will gush out of the process tube if you cut it open after shutdown . Remedy Check the whole machine , particularly those locations which are liable to leak .After leak points have been found ,repair them or replace them with new parts according to specific circumstances ,then evacuate the system and finally charge refrigerant.
- Page 22 Maintenance Service and Trouble Shooting 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 sound can be heard, moreover, there is no periodic change.
- Page 23 Maintenance Service and Trouble Shooting The cause of sudden stop of a compressor during its running is mostly that the gas suction pressure and/or discharge pressure exceed their respective prescribed ranges, thus making a pressure-operated protective relay shut off the power to the compressor and stop it. In the following we discuss mainly the reasons for causing excessively high gas discharge pressure and low suction pressure.
- Page 24 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.
- Page 25 Maintenance Service and Trouble Shooting a) Check the input power circuit to see whether where is voltage of the power supply, namely, the circuit which is connected to the knife switch. This can be determined with an avometer or a test pencil. If a blown fuse is found, ascertain and remove its cause, then replace it with a new one of the same specifications.
- Page 26 Maintenance Service and Trouble Shooting 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.
- Page 27 Maintenance Service and Trouble Shooting 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".
- Page 28 Maintenance Service and Trouble Shooting dissipation make the compressor running without stop. F. Electric leakage of refrigerator 1) Slight electric leakage Electric insulation has deteriorated due to being affected with damp, thus resulting in slight electric leakage. 2) Serious electric leakage Refrigerator case has become live due to faults occurred in some electric devices or the erroneous wiring in installing power cord plug or outlet by the user.
- Page 29 Maintenance Service and Trouble Shooting 4) Inspection method To find the sources of noise, press the vibration spot with your hand while the refrigerator is in operation and listen attentively whether the vibration becomes weaker or vanishes. If the refrigerator has not been levelly placed ,put a level meter on its top table and adjust the leveling screws on its legs .In case noise occurs from the compressor ,strike different locations on the side surface of its case using a rubber hammer or...
