First, the common failure phenomenon of the refrigerator:
1. Leakage caused by refrigerant leakage, electrical (circuit, body) insulation damage, etc.
2. The cooling system is dirty and blocked, and the condenser is dusty.
3. The wire is disconnected, the fuse is blown, the overload protector contact is disconnected due to overheating or overcurrent, and the pressure relay contact is disconnected due to the abnormal pressure of the refrigerator refrigeration system.
4. Compressor motor windings, fan motor windings, solenoid valve coils, relay coils and contacts are burned.
5. The compressor is stuck, the moving parts are stuck, and so on.
6. The compressor valve is damaged, the piston is pulled, the fan blade is damaged, and various components are damaged.
How to check whether there is any failure in the freezer
Is the surface of the freezer too dirty? Has the freezer not been defrosted for a long time? Is the freezer not broken? Is the refrigerator's power supply undamaged, or is it turned off? Whether the temperature set by the switch is appropriate; whether there are obstacles in front of the freezer; the refrigeration capacity of the freezer is too small and needs to be checked by professionals;
Whether the refrigerator uses heating elements, such as heating equipment; whether strong sunlight enters and directly illuminates the surface of the refrigerator; whether certain substances are missing in the refrigerator; whether there are some unknown substances in the refrigerator.
Some phenomena in use seem to be problematic, but this is not a malfunction. Therefore, when the cooling effect is unsatisfactory, the above-mentioned reasons are excluded first.
Don't mistake the normal phenomenon as a malfunction, rush to ask the after-sales personnel to repair it, and spend some money; some phenomena are caused by improper operation, and the user should be able to adjust it by himself. Lack of refrigerant in refrigerators is common and control circuits do not work properly. The thermal protection function of the press does not work, the press is damaged, the external fan does not rotate, the external condenser is too dirty, and the pipeline is blocked.
