Freezers are an indispensable piece of household appliances. After long-term use, more or less problems will occur. If you have to call the master every time you have some minor problems, it will be a waste of money and also Toss people. Therefore, the editor will give you a detailed introduction to several common freezer problems and their maintenance.

　　 　　 Skills Collection

　　NO.1 Freezer "leakage"

Some refrigerators are prone to generate static electricity during long-term use, which requires users to use three-pin sockets. However, some three-pin sockets do not have a ground wire at all, so the generated static electricity cannot be discharged in time, resulting in "leakage ".

　　 Otherwise, if the electrical components of the refrigerator are damaged, the power cord is damaged, etc., the leakage can be solved after repairing.

　　 　　NO.2 Freezer defrost

　　Some refrigerators need to be defrosted, but manual defrosting of refrigerators is time-consuming and a waste of money. , And the defrosting effect is not satisfactory. Teach you a little trick, according to the size of the refrigerator freezer, cut a slightly thicker plastic film, and correctly paste it on the frosted wall of the freezer. You can paste it without any glue. When defrosting, first take out the food in the refrigerator compartment first, then peel off the plastic film and shake it, all the frost can fall off, then re-attach a film, put it in the food, and continue using it. Is it very convenient?

　　 　　NO.3 Compressor is noisy

　　 Carefully check whether the screws at the bottom of the compressor are stable, whether they fall off or become loose, whether there are anti-vibration rubber pads, whether the bottom plate screws are tightly installed, whether the freezer is placed smoothly, and whether the place where they are placed is firm. If there is still noise after eliminating these conditions, please carefully decide whether to replace the compressor.

　　NO.4 Freezer blocking ice

　　 When replenishing refrigerant, connect a large cubic freezer filter in series between the process port and the refrigerant cylinder connecting pipe valve. Used to filter out impurities and residual moisture in the refrigerant. It can prevent the occurrence of ice block. This filter can be reused after being dried at 75℃~100℃ or replaced with blue silica gel.

　　NO.5 The compressor has a "shaft holding" or "cylinder jam" failure

We usually check and repair refrigerators and air conditioners. Sometimes we find that the compressor cannot start normally after power-on. Listen carefully, you can hear the compressor humming. After a while, the thermal protector returns to its original state. The machine power supply, the failure will soon reappear.

　　* Percussion method: Use a wooden hammer to strike around the compressor, and then power on to start. If the axle holding is not serious, the compressor may resume work after such treatment.

*Immersion method: If the compressor of the refrigerator is stuck due to being left unused for a long time, it cannot be started, and cannot be resumed by the knock method. You can remove it from the refrigerator, block the three nozzles, and then It is left upside down for more than 24 hours, so that the machine parts are fully immersed in the lubricating oil, and then subjected to percussion treatment, the boat can return to normal.

　　*If it still doesn’t work, find a maintenance person

　　 In short, pay attention to one point. When repairing, try to choose when the weather is low and the temperature is low to minimize the damage to the freezer. After the repair is completed, test run for 1-2 hours before starting. A collection of maintenance tips, have you learned it?
