This is caused by a certain malfunction inside the refrigerator.

Causes and solutions:

1, the life of the refrigerator has reached the age of replacement: the voltage of the refrigerator in the normal situation, but the compressor can not run properly, there is noise and rotating sound. Once the compressor fails, the refrigerator will not cool.

Solution: at this time you need to ask a professional repairman to replace the compressor. If the fuse of the compressor is blown, first of all, the fuse should be replaced for the refrigerator, and then the compressor should be cooled down to avoid the second burnout. If the life of the refrigerator has reached the age of replacement, then get a new refrigerator.

2. Refrigerator refrigerant is insufficient: refrigerator refrigerant is insufficient, the most likely to happen is the refrigerator condensate tube failure leads to condensate leakage, and then affect the refrigerator cooling effect.

Solution: you need a professional repairman to come to your home to repair, and then repair the condenser tube, plus the right amount of refrigerant.

3. Refrigerator filter blockage: the role of the filter is to adsorb impurities, but a long time, there will be a large number of impurities on the filter, the refrigerator will run up the burden will be aggravated resulting in the inability to operate normally, so the refrigerator cooling effect is not good may be a blockage of the filter.

Solution: regular best every once in a while to clean the filter.

4. Refrigerator air outlet is blocked: refrigerator air outlet is blocked will lead to food can not keep fresh, so that the user produces a refrigerator does not cool the feeling.

Solution: check the refrigerator air vents on time, to ensure that the air vents are unobstructed, in order to improve the cooling effect of the refrigerator, to extend the service life of the refrigerator.

Rongsheng refrigerator temperature adjustment method:

1. Adjust the refrigerator thermostat knob: Due to the large temperature difference between summer and winter, in order to achieve power saving and ensure the quality of frozen food, it is necessary to adjust the refrigerator thermostat knob in the summer and winter.

2. Thermostat knob adjustment: Rongsheng refrigerator temperature control knob is generally 0, 1, 2, 3, 4, 5, 6, 7 when, the larger the number, the lower the temperature in the freezer. General spring and fall days only need to be put on the 3 gear. In order to achieve the purpose of food preservation and power saving, you can play to 1 or 2 gears in summer, and 4 or 5 gears in winter.

Expanded information:

Rongsheng refrigerator freezer room in the temperature is generally in the range of 4 to 8 degrees, to the winter, the room temperature is close to this temperature. The refrigerator compressor rarely starts if the thermostat knob is still at 3 or less. Although the temperature in the freezer can meet the requirements, but the freezer temperature can not reach minus 18 degrees, food is easy to deteriorate, serious food thawing and melting.

Summer with Rongsheng refrigerator temperature is relatively high, if the thermostat knob is still 3 or greater than 3, the refrigerator freezer in order to achieve the temperature requirements, the compressor starts frequently. Although the freezer temperature can reach minus 18 degrees, but it causes a waste of electricity, shortening the service life of the refrigerator. So correctly adjust the refrigerator thermostat knob both fresh, and save electricity.
