Excuse me, which position of the refrigerator is the coldest, 1 or 7?

Generally, the temperature control knob of refrigerator is 0-7. The higher the number of gears, the lower the temperature. The zero gear is the stop gear, and the highest gear is the forced cooling gear.

Gear adjustment of mechanical temperature control refrigerator

1, change gears 2-4 in summer.

The working principle of refrigerator is heat transfer between ambient temperature and indoor temperature. The greater the temperature difference, the longer the refrigerator runs and the more power it consumes. Therefore, the temperature should be slightly higher in summer, and the gear can be set at 2-4 to reduce the gap with the ambient temperature. This can not only ensure the temperature required for food preservation, but also reduce the working pressure of refrigerator, reduce the operating burden of compressor and save some electricity in hot summer.

2. Adjust to the fourth gear in the spring and autumn.

The temperature is moderate in spring and autumn. Similarly, the refrigerator can also be set at about 4 gears.

3. Gear setting in winter 4-6.

In winter, when the ambient temperature is lower than 10℃, the refrigerator will not start. At this time, it is necessary to turn on the low temperature compensation switch (this switch is only available in old refrigerators), and all new refrigerators are changed to magnetic control switches to automatically control the start and stop of low temperature compensation without manual adjustment. At the same time, the temperature control knob will be adjusted to 4-6 to ensure the normal operation of the refrigerator.
