Check point Indication Cause of trouble -- Does the compressor operate? -- Is the refrigerator installed a sufficient distance from any direct heat source? -- Is the condition of the condensors radiation satisfactory? -- Are there any hot foodstuffs in the refrigerator? -- Are there excessive storage foods in the refrigerator,causing interference with the circulation of cold air.
- Page 14 Maintenance Service and Trouble Shooting 3 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 Maintenance Service and Trouble Shooting 4 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...
- Page 16 Maintenance Service and Trouble Shooting a) Listen to the noises produced when the compressor is running 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 higher than the ambient temperature ;if you touch it with your hand ,you will have a sense of slight heat .In case dew condensation appears due to the fact that its temperature is obviously lower than the 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 .
- Page 18 Maintenance Service and Trouble Shooting make a note of from where it leaks ---welding points and parts .After having them repaired ,recharge refrigerant . There many joints sealed surfaces 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...
- Page 19 Maintenance Service and Trouble Shooting Remedy After shut down for several minutes ,open the tubing ,evacuate it and then recharge the system with refrigerant . 4) Low efficiency of compressor 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...
- Page 20 Maintenance Service and Trouble Shooting phenomenon and other several trouble are tends to be confused .Generally speaking ,you can make a judgment based on the frost formed on the evaporator .If the frost does not cover the evaporator , and moreover ,it is loosely formed ,you can make a judgment that the deterioration of refrigerating effect is due to the accumulation of refrigerating oil left in the evaporator tubing in case no other troubles have been found .
- Page 21 Maintenance Service and Trouble Shooting compressor can be started easily (if there is no damage to the compressor parts) and its operating current becomes low ,its gas suction pressure is high and discharge pressure is lower ,the gas discharge tube feels rather cold ,no sound of gas eruption from the liquid in the evaporator can be heard ,and no will gush out of the process tube if you cut it open after shutdown .
- Page 22 Maintenance Service and Trouble Shooting accumulates there, the whole filter screen may be blocked totally, making the refrigerant unable to go through. Clogging with 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,...
- Page 23 Maintenance Service and Trouble Shooting swing drastically and the discharge pressure is very high. In the both cases, stop the compressor at once, and if technique is available, open the cylinder cover and check up the valve block, repair it, or replace it with a new one, C.
- Page 24 Maintenance Service and Trouble Shooting then charge it with refrigerant. 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.
- Page 25 Maintenance Service and Trouble Shooting 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.
- Page 26 Maintenance Service and Trouble Shooting Analysis of Trouble When motor windings have been burned or short-circuited between turns, the fuse will be blown repeatedly, and the blowout occurs particularly at the instant when you close the knife switch. Remedy Check the terminals and the outer casing to see whether they are short-circuited, and measure the resistance of each phase with an avometer.
- Page 27 Maintenance Service and Trouble Shooting E. Compressor won’t stop Sometimes, the compressor will run continuously(for several hours or run without end), If the food placed in the refrigerator is not too much, there may be the following two situations: i) the refrigerator very low, this means that the control system is probably out of order;...
- Page 28 Maintenance Service and Trouble Shooting refrigerator will rise and makes the compressor running continuously. Remedy Check the heat-insulation layer for its damaged parts, repair it to improve its heat-insulation property. If the door has deformed or the door seal is not tightly sealed against the case body, repair them, respectively.
- Page 29 Maintenance Service and Trouble Shooting 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 .
