for those serious cases. Refrigerators are generally of larger volume ,once troubles appear ,to send them to a service department is really a tough ℃ due to the heat produced when compressing refrigerant .Most of the heat radiates to the air through the compressor casing ,therefore ,its casing - Haier 102102429 | User Manual - Page 17
trouble indicating instrument mounted on the domestic refrigerator ,locations and natures of troubles should be determined according to their respective features ,therefore ,experience in servicing is very important to troubleshooting .Service of temperature drop inside freezer compartment .It is - Haier 102102429 | User Manual - Page 18

phenomena may occur simultaneously due to a certain trouble .With this method ,you can reject some suspicious troubles and finally make a correct judgment . 7 Analysis of Troubles and Troubleshooting A. Poor Refrigerating Effect The so-called "poor refrigerating effect " refers to the fact that the - Haier 102102429 | User Manual - Page 20
Maintenance Service and Trouble Shooting There are so many joints and sealed surfaces in a 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 - Haier 102102429 | User Manual - Page 21
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 . - Haier 102102429 | User Manual - Page 22
(or only a little frost ) appears on the evaporator ,and the refrigerator temperature does not drop down is called "no refrigerating". There are many causes for this trouble and it is relatively complicated , too . In servicing ,special attention to finding direct causes for this phenomenon .Three - Haier 102102429 | User Manual - Page 23

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 it is too hot, this is also helpful to the troubleshooting; secondly, measure the pressures at the high and low pressure - Haier 102102429 | User Manual - Page 25
Maintenance Service and Trouble Shooting The cause of sudden stop of a compressor during the system with a proper quantity of refrigerant. b) Air left in the system Analysis of Trouble The residual air in the system will circulate together with the refrigerant in the system. The major symptoms caused - Haier 102102429 | User Manual - Page 26
. 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 - Haier 102102429 | User Manual - Page 27
Maintenance Service and Trouble Shooting a) Check the input power circuit to see whether where motor not running or humming. 2) Check the circuit voltage to see whether it is normal. Analysis of trouble If the circuit voltage is obviously lower than its rated value, it will be difficult to start the - Haier 102102429 | User Manual - Page 28

If short circuit occurs or the resistance of situations: i) the refrigerator very low, this means that the control system is probably out of order; ii) the control system works normally, and there are troubles in the refrigerating system or other - Haier 102102429 | User Manual - Page 29
. If the evaporation temperature is too high, settle this problem with an appropriate quantity of refrigerant. 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 - Haier 102102429 | User Manual - Page 30
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 - Haier 102102429 | User Manual - Page 31
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 - Haier 102102429 | User Manual - Page 32
