What exactly does the refrigerator temperature control file 1234567 mean?

1 gear control temperature is about 9 degrees, and 7 gear control temperature is about 1 degree.

When the outdoor temperature is high in summer, it can be adjusted to 3-4, generally around 4℃-6℃.

In winter, the ambient temperature is low, which can be adjusted to 5-7, and the temperature is generally around 2℃-4℃.

In spring and autumn, the temperature can be adjusted to 2-3.

When the room temperature is lower than 10℃, the thermostat should be set to "6". Some refrigerators have zero gear, which means that the refrigeration can be turned off. You can also follow the instructions on the refrigerator.

Cause: The ambient temperature is high in summer (up to 30℃). If the freezing room temperature is at a high level (4, 5) and below-18℃, the temperature difference between inside and outside will be very large, and the temperature in the cabinet will be difficult to drop 1℃ every time. Moreover, the loss of cold air through the insulation layer of the box and the door seal will also be accelerated, resulting in long start-up time and short shutdown time, resulting in long-term high-temperature operation of the compressor.

At this time, if the refrigerator is shifted to the weak gear (gear 2 and gear 3), the start-up time of the refrigerator will be obviously shortened, the wear of the compressor will be reduced and the service life will be prolonged. So when the temperature is high in summer, adjust the temperature control to a weak level. When the ambient temperature is low in winter, if the thermostat is still set in a weak position and the temperature difference between inside and outside is small, the compressor will be difficult to start, and the refrigerator with single refrigeration system may be frozen in the freezing room.

Extended information:

The thermostat of the refrigerator automatically controls the start and stop of the refrigeration compressor within a certain temperature difference range according to the temperature requirements of the refrigerator, so as to keep the temperature in the refrigerator within a given value range.

For the indirect cooling refrigerator with forced convection cooling, in addition to the thermostat, there is also a temperature-sensitive damper (also called automatic damper thermostat), which realizes temperature control by automatically adjusting the amount of cold air entering the refrigerating room.

Different refrigerators have different thermostats. Some thermostats are marked with numbers to indicate the temperature.

There will be the words "no parking, no cold" on the sign. The refrigerator thermostat indicates that in this position, the compressor of the refrigerator will keep running and realize refrigeration. After refrigeration, the refrigerator thermostat should be adjusted to the original value immediately to avoid damaging the refrigerator. However, this setting is usually not used when setting the thermostat.

When the thermostat of the refrigerator is set to the 0 position, the refrigerator will stop working, which is mainly used for manual defrosting. After defrosting the refrigerator, the thermostat of the refrigerator will be adjusted to its original position, and the refrigerator can start working normally again.
