To keep food cold and fresh but not frozen, it should be set somewhere between 3-5°C (37-40°F). Some fridges have a temperature reading, but most have a numbered dial. This usually goes from 1 to 5, with 5 being the coldest.
Your refrigerator should be set at or below 40°F (4°C) to keep food safe and prevent bacterial growth. Ideally, the temperature for the refrigerator is around 37°F (3°C). For the freezer, the temperature should be 0°F (-18°C) or lower.
FDA Refrigerator Temperature Recommendation
Most people understand that your refrigerator should not be set at or below 32 degrees, as you don't want your food to freeze. The reason why we keep food cold is to minimize the opportunity for potentially dangerous bacteria to grow and infest your food.
On a refrigerator with settings numbered from 0 to 7, 7 is the coldest setting. Setting the dial to 7 will lower the temperature, making it colder, ideal for preserving food safely and extending its freshness, especially in warmer conditions or when the fridge is fully stocked.
Most experts recommend that the ideal temperature setting for a refrigerator is between 35-38°F (1.6-3.3°C). This temp ensures food safety by giving a 2-5 degree buffer in case the temperature gauge isn't wholly accurate.
The proper refrigerator temperature for fresh food. The ideal refrigerator temperature is about 37°F (3°C). However, a range of 33–40°F (0–4°C) is generally accepted as safe for most purposes.
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. Aim to stay between 35° and 38°F (or 1.7 to 3.3°C).
You should keep your fridge temperature set at 3°C/37.4F and your freezer set at -19°C/-2.2F (or -18°C/-0.4F, depending on your model) all year-round.
The ideal fridge temperature is between 0°C and 5°C.
However, the average temperature of fridges in the UK is 7°C!
To keep food cold and fresh but not frozen, it should be set somewhere between 3-5°C (37-40°F). Some fridges have a temperature reading, but most have a numbered dial. This usually goes from 1 to 5, with 5 being the coldest.
If your fridge is too cold, it may be that there is internal damage. A build-up of frost inside a fridge/freezer is caused by an interaction between warm and cold air. A crack in the door seals will also cause your appliance to overcompensate, producing more cold air to keep to fridge temperature stable.
The following is a timeline of low-temperature technology and cryogenic technology (refrigeration down to close to absolute zero, i.e. –273.15 °C, −459.67 °F or 0 K).
To reduce Salmonella growth, eggs gathered from laying hens should be refrigerated as soon as possible. After eggs are refrigerated, they need to stay that way. A cold egg left out at room temperature can sweat, facilitating the movement of bacteria into the egg.
Chilling foods to proper temperatures is one of the best ways to slow the growth of these bacteria. To ensure that your refrigerator is doing its job, it's important to keep its temperature at 40 °F or below; the freezer should be at 0 °F.
Based on these two factors here's the number your fridge should be set on: If you're always storing plenty of food you need the colder settings (3 to 4). If you're not storing as much choose between 2 and 3. If the temperature is very low, ice will form and it may prevent air circulation.
Fridge temperature settings are generally numbered from 1 to 5, with 5 being the coldest. A fully stocked fridge may need to be set to a higher setting (around 3 or 4), whereas one with more space is best suited to temperature setting 2 or 3.
The Food Standards Agency advises household fridges to be set at 5 degrees Celsius or below. This is because harmful bacteria grow best in what is known as the 'danger zone' between 8 degrees and 63 degrees. Fridge design has come a long way.
If your 20-year-old fridge has been running well, and only needs minor repairs once in a while, then it is worth keeping it, instead of replacing it. Though, if it ends up needing a major repair, then you should think about replacing the fridge.
These internal controls show temperature ranges with the numerical ranking of 1-9 with 9 being the coldest.
Keep your appliances at the proper temperatures.
Keep the refrigerator temperature at or below 40° F (4° C).
Typically, the back and bottom of the fridge is the coldest part. This is because cold air sinks down, and the back of the fridge is farthest from the door. It's different for fridges with ice-making compartments at the top, which make the top colder.
The recommended temperature for the refrigerator is 3°C (37.4°F), while for the freezer, it's -18°C (-0.4°F) in Celsius.
It makes sense to keep the fridge temperature at the recommended 4 °C and avoid cutting corners by storing food at a higher temperature. By storing at 7 °C, households will save on their energy bill but likely will throw away more food and have a higher risk of getting foodborne illnesses.
The biggest source of heat in a fridge is the warm air that rushes in every time you open the door. Cold air sinks, so it collects at the bottom and, in a fridge freezer, the bottom shelves will be coldest.
When working properly, the refrigerator temperature should be 40° F (4.4 °C) or below; the freezer, 0° F (-17.8 °C) or lower. After the power comes back on, if you're not sure a particular food is cold enough, take its temperature with a food thermometer.
