Interior Controls with Digital 0-9 Settings Some Bottom Freezer Refrigerators have digital temperature controls located inside the fresh food compartment. These internal controls show temperature ranges with the numerical ranking of 1-9 with 9 being the coldest.
Setting the Temperature
The temperature selection on a Chest Freezer is made by setting the dial from ONE to SEVEN, with SEVEN being the coldest. The normal safe freezing level is obtained by setting the control on FOUR.
What number should your fridge be on? The fridge temperature control does not indicate a specific temperature in degrees but rather the cooling power of the appliance. Fridge temperature settings are generally numbered from 1 to 5, with 5 being the coldest.
Which is colder -15°c or -23°c in freezer? -23 °C is colder in a freezer than -15 °C. That is because with negative numbers, “higher” the number, lower the value.
The temperature of a freezer should be set at 0 degrees Fahrenheit so everything stays very cold. A freezer should be cold enough to keep food frozen and preserve it until they are ready to be cooked or reheated.
The recommended freezer temperature to keep food safe is at or below 0°F (-18°C), making higher temperatures less reliable for long-term freezer storage. However, freezer temperatures may need to be adjusted by a few degrees to account for factors like location, humidity or outside temperatures.
You can always err on the safe side and lower the temperature below 0°F—your freezer can never be too cold. “Most recommendations are for a range of temperatures but in reality, there is no temperature that is too low for freezers,” says Tetro. “Most freezers do have a lower limit of around -10°F (-23°C).”
Food between 0ºC and minus 24ºC
Many freezers permit adjusting temperatures down to -24ºC. That temperature can keep your food in good condition for a long time, but there is the risk that you are demanding too much of your appliance.
Yes, your freezer can be too cold. If this is the case, you may need to adjust the temperature to 0ºF (-18ºC) or shift frozen items around to help encourage proper airflow. Parts of your freezer may also have worn out over time, affecting your appliance's freezing capabilities.
Is 5 degrees OK for the freezer? Yes, 5 degrees Fahrenheit (-15 degrees Celsius) can be an appropriate temperature for a freezer. According to the United States Department of Agriculture (USDA), the ideal temperature for a freezer is 0 degrees Fahrenheit (-18 degrees Celsius) or below.
There should be an adjustable thermostat control somewhere. If it's a fridge/freezer, it's usually in the fridge. If it's a standalone freezer, it's usually outside the cooling area, maybe above the door. Turn the knob in the direction that increases cooling.
1 is the warmest and 7 is the coldest. It is recommended that unless you have some special (and rational) reason to mess with the setting, just leave them at the factory settings. All the settings do is divert resources away from either the freezer or the refrigerator.
Some fridges don't show the temperature but work on a setting that is listed from 1 to 5. The numbers on the fridge's temperature dial indicate the refrigerating power. Therefore, the higher the setting, the cooler the fridge will be. Choosing setting 5 will make your fridge the coldest.
To store frozen foods at best quality, keep the freezer set to maintain zero (0 °F or -17.8 °C).
For the fridge compartment, we recommend maintaining a temperature between 3°C to 5°C to slow bacterial growth and preserve perishable items effectively. Similarly, for the freezer compartment, it is best to set the temperature at -18°C or lower to freeze food solid and maintain its quality over longer periods.
The U.S. Food and Drug Administration (FDA) recommends that your refrigerator temperature should be at or below 40°F, and your freezer temperature at or below 0°F. However, the ideal refrigerator temperature is actually lower.
Turn knobs to lower numbers for warmer temperatures and to higher numbers for colder temperatures. The setting of 5 for both the fresh food and freezer section is the recommended setting for most environments.
The optimal temperature for freezer food storage is 0° F or below. If the temperature is any higher, then you may be experiencing freezer problems.
Your freezer will automatically maintain the temperature level you select. The temperature control dial has 7 settings, plus OFF. "1" is the warmest, "7" is the coldest, and turning the temperature dial to OFF shuts down the compressor.
Freezer frosting is the build-up of frost on the walls and shelves inside a freezer. This can happen when there are fluctuations in temperature or when too much moisture gets into the freezer. The frost can also be caused by air coming into the freezer, which brings humidity and causes it to freeze.
To keep your food fresh and safe, set your freezer to 0°F (-18°C) or lower.
The recommended freezer temperature is typically around 0 degrees Fahrenheit (-18 degrees Celsius). This temperature is cold enough to keep food frozen and prevent bacteria growth and spoilage, ensuring your frozen food stays safe and maintains its quality.
Be sure to check the electrical outlet, thermostat and airflow around vents. Cooling problems can also be caused by dust on condenser coils, faulty gaskets, clearance space around the refrigerator, a broken or stuck condenser fan or a faulty circuit board.
