1、 Siemens refrigerator alarm reason:
1. Siemens refrigerator is started for the first time or after a long power failure.
2. The freezer door is opened for a long time.
3. Put a large amount of food in the freezer at one time.
4. When the refrigerator door is not closed properly or the user opens the door for a long time, an alarm will also be generated for the air-cooled refrigerator.
5. The thermostat of the refrigerator is not adjusted properly.
6. The program in the display board may be subject to external electromagnetic interference, so long as the alarm is not frequent, there should be no problem.
2、 Siemens refrigerator alarm solution:
1. Temperature controller of refrigerator for winter and summer regulation
Due to the large temperature difference between summer and winter, in order to save power and ensure the quality of food freezing, it is necessary to adjust the thermostat knob of the refrigerator in summer and winter.
2. Adjustment method of thermostat knob
The refrigerator temperature control knob generally has 0, 1, 2, 3, 4, 5, 6, 7. The higher the number, the lower the temperature in the freezer. In spring and autumn, we usually put it on level 3, depending on your requirements, whether the freezer can reach below - 18 degrees. In order to keep food fresh and save electricity, we can turn to 1st or 2nd gear in summer and 4th or 5th gear in winter. Some people may ask whether it is wrong to set the temperature low in winter (the value of the thermostat is large) and high in summer (the value of the thermostat is small). In fact, many people have the misconception that the refrigerator temperature can be set higher when the temperature is low in winter, and lower when the temperature is high in summer.
Precautions for using Siemens refrigerators:
1. The placement of the refrigerator shall be reasonable and convenient for cooling. It is also necessary to check the power supply of the family, whether it is grounded and whether it is a dedicated line.
2. Read the instructions carefully Before use, the user should read the attached product instructions carefully and check all parts of the refrigerator. Most household refrigerators use 220V, 50Hz single-phase AC power supply. During normal operation, the voltage fluctuation is allowed to be between 187-242V. If the fluctuation is large or high or low, it will affect the normal operation of the compressor, or even burn the compressor.
3. For electrical safety, the refrigerator should use a single-phase three hole socket with separate wiring. Pay attention to protecting the insulation layer of the power line, do not press the wire heavily, and do not change or lengthen the power line at will.
4. After the refrigerator is allowed to stand for 2 to 6 hours, it should be started again after the startup check is correct to avoid oil circuit failure (the refrigerator after handling). After connecting the power supply, carefully listen to whether the sound of the compressor during startup and operation is normal, whether there is the sound of pipeline bumping each other. If the noise is too loud, check whether the products are placed stably, whether each pipeline is in contact, and make corresponding adjustments. If there is a loud abnormal sound, the power supply should be cut off immediately and professional repair personnel should be contacted.
5. When the new machine is put into use, the load shall be reduced because the moving parts of the new machine have a running in process. After running for a period of time, add a lot more, which can extend the life of the refrigerator.
6. The first time the refrigerator is used for load reduction during the first operation, the stored food shall not be too much, and appropriate space shall be reserved to maintain the circulation of cold air and avoid the refrigerator working at full load for a long time as far as possible. Hot food should be cooled to room temperature before being put in, so as not to cause the refrigerator not to shut down for a long time. The food should be sealed with a fresh-keeping bag or paper or put into a sealed container to prevent the food from being damped, dehydrated and smelling. The food with water should be put in after removing the water, so as not to form too much frost due to the evaporation of a large amount of water. Note that liquid and glassware should not be placed in the freezer to prevent freezing crack and damage. Volatile and flammable chemicals and corrosive acid and alkali materials shall not be put in to avoid damaging the refrigerator.
