In use, attention should be paid to the working status of each component of the refrigerator and the stability of the power supply. Whether the refrigeration, electrical, and wind systems are operating normally. 1. Stability of power consumption: The power supply of the refrigerator must use independent sockets. The current capacity of the socket and power cord must be the same as that of the refrigerator, and the socket must be reliably grounded. When the voltage is unstable, it is recommended to use a regulator with more than five times the voltage and power. Mainly observe the three parts of the refrigeration system, electrical system, and wind system to determine whether they are working properly.
1. Refrigeration system: observe whether there are cracks, breakages, frosts, and condensation on the refrigeration system pipelines; whether there is friction between the refrigeration pipelines, pipelines and the casing, especially the welding of the refrigeration pipelines, and whether there is any seepage at the joints leak. Where there is oil, or wipe the pipe with a clean soft cloth and soft paper. At the road welding and joints, observe whether there is oil pollution and judge whether there is leakage.
2. Electrical system: observe whether the electrical system fuse is blown, whether the wire insulation is intact, whether the circuit board is disconnected, whether the connection is loose, etc., especially whether the electrical connection is in good contact. The connecting screws and sockets are easily loosened, causing poor contact.
3. Air system: observe whether the air filter, heat exchanger coils, and fins have accumulated too much dust; whether the air inlet and outlet are open; whether the fan and fan blades are operating normally;
