Small combined refrigerator repair knowledge and fault method

small combined refrigerator repair knowledge and fault method:
      "1, cold storage door not tightly closed, please adjust the spacing between the hinge and the lock and the door of the garage body.  
      "2, cold not cold or bad refrigeration effect. Check whether the dirty condenser of the refrigerator. Check whether library evaporator frost deposit too thick. Check whether the leakage of refrigerant (junction with soap and water, painted on the pipeline bubbles build instructions refrigerant leakage). And please professional personnel to supplement the refrigerant and treatment on leakage. Check the freezer door seal is intact and to exclude. Check whether the work of cold storage refrigeration machine. Computer controller to check the parameters of the cold storage settings are correct and re adjust. Controller checks whether failure and replacement of cold storage. Clearance check bank piled up goods whether sufficient and dredging of the.
      "3, refrigerating machine start frequent or long time does not start or start a long time does not stop or base temperature to stop. If there is dirt on A, check the condenser, the heat is not good will cause the condenser pressure is too high, in order to protect the compressor, the machine in the pressure under the control of stop, wait for good heat dissipation, press the reset button black pressure controller, machine can automatically restore operation. The parameters of B controller, the setting is wrong, you can re set. C, cooling is not good, please refer to the failure of 2. D, temperature control failure. E, electrical appliances.
      "4, closing after cold storage distribution box has no reaction, and three-phase electric normal. Please check the zero line, whether there is a 220V voltage. Cold storage parts (all valves, controller) has been set, the user need not adjust parts.
      "5, hangar lighting lamp does not light. Please check whether the switch failure, the bulb is damaged. When the examination to cut off power supply, installation should pay attention to the waterproof lamp shade.
      "in 6, when the ambient temperature is too high, running for a period of time after the temperature refrigerator, not to the setting value and the refrigerating machine downtime in advance. This is because the environmental temperature led to the condenser pressure is too high, in order to protect the compressor, the machine in the pressure under the control of stop, wait for good heat dissipation, press the reset button black pressure controller, automatic recovery machine can run. And check the water condenser is good heat dissipation. Can not be arbitrarily adjust the pressure controller set value, otherwise the pressure controller without protective effect of refrigeration machine.
      "7, check the power: no electricity or power distribution box is not displayed on the display screen. Special gate please check whether the failure of cold storage. If the refrigeration machine start frequent or long time does not start or start a long time does not stop or base temperature to stop.
      "in 8, when the machine is running there is abnormal noise, please stop check, whether it is caused by vibration or mechanical failure. Abnormal noise distribution box, this is the voice of the AC contactor, is due to the moving parts of contactor local is not flexible, please switch off then back press iron absorption can eliminate noise contactor. When the ambient temperature is too high, running for a period of time after the temperature refrigerator, not to the setting value and the refrigerating machine downtime in advance. This is because the environmental temperature led to the condenser pressure is too high, in order to protect the compressor, the machine in the pressure under the control of stop, wait for good heat dissipation, press the reset button black pressure controller, automatic recovery machine can run. And check the water condenser is good heat dissipation. Can not be arbitrarily adjust the pressure controller set value, otherwise the pressure controller without protective effect of refrigeration machine.
