  • Page 17: Troubleshooting

    TROUBLESHOOTING 1. Analysis of Troubles and Troubleshooting A. Poor Refrigerating Effect The so-called “poor refrigerating effect “ refers to the fact that the refrigerator can operate and refrigerator normally, but the temperature in the refrigerator cannot drop to the prescribed value under the stipulated working conditions.
  • Page 18 Remedy According to the operating procedures, it is mandatory to turn the machine off, and several minutes later, open the refrigerant charging tube and let the refrigerant escape from it, replace the dry filter, recharge refrigerant after evacuating, and then seal the charging port. 3) There is air left in the refrigerating system Analysis of Trouble Residual air in the refrigerating system will reduce its refrigerating efficiency .The prominent...
  • Page 19 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 20 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. 2) Refrigerating system has been clogged a) Clogged with Ice Analysis of Trouble The dryness treatment for the major parts in the refrigerating system has been performed...
  • Page 21 Remedy Dismantle the system, remove the dry filter from it, purge the tubing with nitrogen, install a new filter, then evacuate it and finally charge it with refrigerant. C) Clogging in filter Analysis of Trouble Total clogging of a filter is rarely to occur. The paste-like matter formed from the substances filled into the system mostly causes this trouble or other dust after the refrigerator has been used for a longer time, or by the dirt accumulated gradually inside the filter.
  • Page 22 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 23 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.
  • Page 24 b) Check the compressor accessories, including its thermal protector and relay. In case the thermal protector is damaged, the compressor cannot be powered on. If the relay is out of order, the motor will not run and hum sound can be heard from it after the compressor is turned on, in that case, shut it down immediately, otherwise, the motor windings will be burned out in case this condition lasts longer.
  • Page 25 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 megametre can be used in this inspection, too. If the insulation resistance is lower than 2 M , this means that the insulation layer is already breakdown.
  • Page 26 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; ii) the control system works normally, and there are troubles in the refrigerating system or other parts.
  • Page 27 Analysis of Trouble When the heat-insulation layer inside the case body deteriorates or the door seal is not closely touches the doorframe, the temperature in the 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.
  • Page 28 power supply circuit have been inversely connected accordingly ,this makes the null line become a live wire . G. Stronger vibration and loader noise 1) Refrigerator placed improperly a) Uneven ground Uneven ground will cause the refrigerator to be placed unsteadily, causing stronger vibration and noise during its operation.
