the 7th gear is cold.

the coldest file of refrigerator 1-7 is file 7, which is also called quick freezing file, and is suitable for items that need to be frozen urgently. Try to reduce the time when the refrigerator works in the 7th gear. Being in the quick-freezing gear for a long time may cause damage to the refrigerator freezer, and the 7th gear has the lowest temperature and consumes the most electricity. The compressor always works without stopping. Generally, it is only used for quick freezing food for several hours, but not more than 4 hours.

for daily use, don't adjust the gear to the 7th gear. It's better to adjust the gear according to the seasonal ambient temperature. Adjust it to the smaller digital gear in summer, the middle gear in spring and autumn, and the larger digital gear in winter. Keep the freezing room at MINUS 18 degrees and the refrigerating room at 4-8 degrees.

the refrigerator gear should be adjusted according to the change of external temperature, and changing the gear control can effectively reduce power consumption. Many computers use computers for temperature control. The biggest feature of computer-controlled refrigerators is accurate temperature control without manual temperature compensation switch. That is, there is no need to regulate the temperature manually.

1. How to use the refrigerator thermostat. During the use of the refrigerator, its working time and power consumption are greatly affected by the ambient temperature, so it is necessary to choose different gears for use in different seasons. The refrigerator thermostat should be turned on at low gear in summer and at high gear in winter.

2. When the ambient temperature is high in summer, it should be used in weak gears 2 and 3, and when the ambient temperature is low in winter, it should be used in strong gears 4 and 5. Reason: In summer, the ambient temperature is high (up to 3℃), and if the temperature in the freezer is set in strong gears (4 and 5), it will be below -18℃, so the temperature difference between inside and outside is large.

furthermore, the loss of cold air through the insulation layer of the box and the door seal will also be accelerated, which will lead to a long start-up time and a short shutdown time, which will lead to a long-term operation of the compressor at high temperature, which will consume electricity and easily damage the compressor.

3. If you change to the weak gear (gear 2 and gear 3) at this time, the starting time of the refrigerator will be obviously shortened, and the wear of the compressor will be reduced and the service life will be prolonged. Therefore, when it is hot in summer, the temperature control will be adjusted to the weak gear.

4. When the ambient temperature is low in winter, if the thermostat is still set to the weak position, the temperature difference between inside and outside will be small, so it will be difficult for the compressor to start, and the refrigerator with single refrigeration system may also freeze in the freezing chamber.
