4. Ўстаноўка і налада

WARNING: Installation of this inverter compressor requires specialized knowledge and tools. It must only be performed by certified technicians experienced with inverter refrigeration systems and R600a refrigerant. Improper installation can result in serious injury, property damage, or system failure.

4.1 Праверкі перад устаноўкай

1. Праверце сумяшчальнасць: Ensure the FLD165NBMA is the correct replacement part for your refrigerator model. Check the refrigerator's serial number and consult LG's service documentation if unsure.
2. Меры бяспекі: Disconnect the refrigerator from the power supply. Ensure proper ventilation in the work area.
3. Абыходжанне з холадагентам: R600a is a flammable refrigerant. All procedures involving refrigerant must be performed in a well-ventilated area, away from ignition sources, and by technicians certified in handling flammable refrigerants.

4.2 Installation Procedure (Technician Only)

The following steps are a general outline. Technicians must follow LG's specific service manual for the refrigerator model being serviced.

1. Аднаўленне холадагенту: Safely recover the existing R600a refrigerant from the system using appropriate recovery equipment.
2. Адлучэнне электрычных злучэнняў: Carefully disconnect all electrical wiring from the old compressor.
3. Зняць стары кампрэсар: Desolder or unbolt the old compressor from the refrigeration system.
4. Падрыхтоўка новага кампрэсара: Inspect the new FLD165NBMA compressor for any shipping damage.
5. Усталюйце новы кампрэсар: Solder or bolt the new compressor into place, ensuring proper alignment and secure connections.
6. Эвакуацыя: Evacuate the refrigeration system to remove all non-condensable gases and moisture.
7. Зарадка холадагенту: Charge the system with the precise amount of R600a refrigerant specified by the refrigerator manufacturer.

5. Прынцыпы працы

The LG FLD165NBMA is an inverter compressor, meaning its operating speed can vary to match the cooling demand of the refrigerator. This results in more stable temperatures, reduced energy consumption, and quieter operation compared to traditional fixed-speed compressors.

Once installed and the refrigeration system is properly charged, the compressor will automatically regulate its speed based on the refrigerator's internal temperature sensors and control board signals. There are no user-adjustable operating settings directly on the compressor itself.

6. Тэхнічнае абслугоўванне

As a sealed component of the refrigeration system, the LG FLD165NBMA compressor itself requires no routine user maintenance. However, general refrigerator maintenance contributes to its longevity:

• Трымайце кандэнсатарныя шпулькі ў чысціні: Regularly clean the condenser coils (usually located at the back or underneath the refrigerator) to ensure efficient heat dissipation. Dirty coils force the compressor to work harder.
• Забяспечце належную вентыляцыю: Maintain adequate space around the refrigerator for proper airflow.
• Ушчыльняльнікі дзвярэй манітора: Ensure refrigerator door seals are intact and sealing properly to prevent cold air loss, which can overwork the compressor.

Any internal system maintenance, such as refrigerant checks or repairs, must be performed by a qualified technician.

7. Выпраўленне непаладак

If your refrigerator is experiencing issues after compressor replacement, consider the following common troubleshooting points. Remember, all diagnostics and repairs should be conducted by a qualified technician.

7.1 Compressor Runs but Does Not Cool (No Compression)

If the compressor is running (you can hear or feel it vibrate) but the refrigerator is not cooling, this indicates a lack of compression or refrigerant circulation. Possible causes include:

• Insufficient Refrigerant Charge: The system may be undercharged or have a leak.
• Overcharge of Refrigerant: Too much refrigerant can also hinder proper operation.
• System Blockage: A blockage in the capillary tube or filter drier can prevent refrigerant flow.
• Faulty Compressor: Although new, a compressor can rarely be defective, failing to build pressure.
• Electronic Control Issue: The inverter board or main control board might not be sending correct signals to the compressor.

Action: A technician must check refrigerant pressures, inspect for leaks, and diagnose the electronic control system.

7.2 Compressor Does Not Start

• Няма харчавання: Check the refrigerator's power supply and circuit breaker.
• Faulty Control Board: The main control board or inverter board may be defective, failing to send a start signal.
• Праблемы з праводкай: Loose or incorrect electrical connections to the compressor.
• Overload Protector/Start Relay: While inverter compressors have integrated controls, issues with the power module can prevent starting.

Action: Verify power, then a technician should inspect wiring and test control boards.

7.3 Unusual Noises from Compressor

• Няшчыльнае мацаванне: The compressor might not be securely mounted, causing vibrations.
• Internal Mechanical Failure: Rare for a new unit, but possible.

Action: A technician should inspect mounting and diagnose internal compressor health.
