Refrigerator is now the necessary furniture for every family to add to our food. At the same time, some food reserves are the preferred place. However, when households use refrigerators, there are often severe problems and malfunctions, which may be due to overloading or long hours of use, coupled with inadequate maintenance, often such problems arise in refrigerators, which need to be resolved in a timely manner where the failure is known. Now, the editor shows you a few common refrigerator failures and how they are handled。
Common failure management methods for refrigerators
I. Refrigeration
The temperature in the refrigerator is high, and there are two scenarios: first, the fluorine leaks in the refrigeration system, i. E., there is no refrigerant. Although the refrigerator has been operating, the temperature in the container cannot decrease, and after a long period of time, the food in the container will break down, so it will have to be repaired in a timely manner. As long as it is not a new refrigerator, the situation is very slow, with the first half of the freezer having frost, the other half having no frost, the thicker side of the frost, and the longer-term absence of frost in the freezer, at which point only water balls may appear and the temperature in the box is higher. Such refrigerators are generally difficult to repair because of the difficulty of finding leaks, so they cannot be repaired for longer periods of time, when they can be handled through oxygen welds if found outside。
The second reason for the high temperature is the evaporation unit, the internal frost, which is mainly a wind freezer, which has only one evaporation unit, which, when the evaporation unit is unable to melt, can jam the windway, the amount of cold cannot go out, and so the refrigerator cannot cool. The reason for this is that there's a problem with the frosting system, it could be that the frosting timer has a malfunction, or the heat pipe has been burned。
2. Compressors cannot initiate treatment
(1) if the refrigerator has a power source, we can open the cooling room door, if the internal lamp is lighted, indicating that the refrigerator has electricity, if not, we can check the total power supply for electricity, then check the refrigerator fuse (not all refrigerators) and finally check if there are any problems with the thermostats。
(2) the compressor's failure to burn allows for the examination of whether the electrical wire has been burned and, finally, of the starter's condition, sometimes overheating, which takes some time before the compressor's temperature is reduced。
(3). The thermostat cannot be reset and is indissociable from the point of contact by burning together
Ii. Vibration by condensers
1. Reason analysis:
In the course of the use of refrigerators, there are times when the condensers can be heard dithering or cracking, which is often on the shutters, so that the condensers squeeze the cooling tube on the window pane to form a whole, but in the production process, or for other reasons, often result in solid variations in the combination of the cooling tube and the radiator, which, in the operation of the compressor, results in discomfort, which causes the cooling tube to break and the cooling tube to leak, because of variations in temperature inside and outside the condensor tube and the difference in the heat-inflation coefficients between the cooling tube and the radiator, which creates a flattering sound, which temporarily does not affect the use of the freezer, but which causes a long-term noise, which causes the cooling tube to break and causes the refrigerant to leak。
Method of exclusion:
Stop the compressor, and then drop 502 glues in the cooling tube and the distillation tablet, and then start the compressor after a day, and there's no sound。
This is illustrated by the frequent failure and handling of refrigerators. The main ones are refrigerators that are not cool and condensers that vibrate. These are problems that are common to most users, and it is not necessarily the same reason that we need to analyze the malfunctions and then treat the symptoms so that the problem can be solved. The above, the method of exclusion described by the author is more detailed, and consumers can analyze the problem in case of conflict in their refrigerators, based on the method presented by the writer。
