A Complete Refrigerator Temperature Guide For You!

A refrigerator is one of the most important appliances around the household. It helps you store food and milk for longer use, and the supply of cold water bottles from the refrigerator in the scorching doesn’t ever hurt.

However, if your refrigerator isn’t set on the right temperature, it can harm the food. A higher than needed temperature can make your food go bad and bacterial, and the lower temperature can cause some items to show frost on them, which mean they would require defrosting before you can use them.

In other words, the right temperature of your refrigerator can keep the food and drinks on the optimal condition. However, this right temperature depends on the type of food items stored in the refrigerator. Secondly, each partition in the refrigerator differs in temperature, which makes it easy to store different items requiring different temperatures in different sections of the refrigerator.

What is refrigerator temperature?

Starting from the basics, what exactly is a refrigerator temperature? Well, a refrigerator temperature is a way to keep your food stored in the refrigerator fresh and safe from bacteria.

Suppose if you put milk in the refrigerator and the temperature is not low enough to keep the milk cooled, the milk will go bad. Therefore, the right temperature is necessary to keep the food stored properly for long use.

What is the minimum temperature a refrigerator can provide?

Typically, refrigerators range from 1 to 7 degree celsius, which means the lowest your refrigerator can go to is 1 degree C.

Below 1 degree is a freezing temperature, and you don’t want your refrigerator to freeze your food.


What is the best temp for a refrigerator?

You just bought a new refrigerator and want to store a box of milk right away, what do you do? The temperature dial comes without any indication and the manual booklet rarely have any details about the temperature dial (also, it’s very verbose, who would read that, anyway?). It’s a mystery.

Well, let’s get this mystery solved right away.

Although your refrigerator can go as low as 1 degree C, the best temperature for your refrigerator, according to Food Developmental Authority, is 3 to 4 degree – with 4 degree C being the most ideal choice in most cases.

Below 1 degree is freezing temperature, and you have a freezer for that so you wouldn’t want your food stored in the refrigerator to get frozen. 4 degree C is a good temperature, ideally, to keep your food and drinks cold enough to prevent bacterial growth and not let the food freeze up.

On newer models of smart refrigerators, a screen or a smartphone app usually helps selecting a temperature directly instead of playing with the dial.

But if you have a traditional refrigerator and don’t know how temperature degrees are defined by the temperature dial, read the next answer.


Is it the higher or lower number in the refrigerator that makes it colder?

Every refrigerator has he same rules when it comes to temperature settings through a dial. The number on the dial, as opposed to the contrary misconception, don’t denote the degrees, they actually denote the refrigerant power. It means the the higher the number the set, the colder the refrigerator will be.

For instance, if your refrigerator has a dial ranging from 1 to 7, setting your refrigerator to 7 will keep it the coldest, and setting it to 1 will keep your refrigerator the warmest in comparison.


What are the highest temperature degrees in a mini refrigerator?

A compact or a mini refrigerator is used for temporary storage of food. Thus, the temperatures in such a refrigerator are different from a typical one.

In a mini refrigerator, the temperature ranges typically from 1.5 degree C to 5.5 degree C (35-42 degrees Fahrenheit).


Which side to turn for the mini refrigerator to become colder?

Mini refrigerators maintain temperature similarly to a full-sized refrigerator. The higher numbers in the dial keep the food colder and lowest numbers keep the warmer.

The placement of the compact refrigerator, the room temperature, and the heating appliances situated near the refrigerator can all affect how the temperatures are maintained in the refrigerator.

Make sure the outer environment is not heated enough to affect the performance of the mini refrigerator. And if the outer temperature is not controllable, make sure the dial is set to the higher numbers so your food remains cold and safe.


How to tell if my freezer is set to the correct temperature?

The freezer is used to actually freeze up your food and not just cool it. For example, water bottles should be in the refrigerator because you want your water cold and ice should be stored in the freezer because you actually want it frozen.

If your food and drinks aren’t freezing up properly on the initial setting, make sure to switch the dial to a lower temperature. Depending on the model and brand of the refrigerator, your dial can be located on the inner sides, on the ceiling of the freezer, on the door, or at the top center of a compartment.

On the other hand, some freezer dials actually show the temperature in fahrenheit or celsius (depending on the manufacturer) while some only have a temperature dial with usual numberings that represent the freezing power. A higher number will ensure proper freezing.

If a number you set isn’t resulting in frozen food, it might be because your freezer is very crowded and it needs a higher power to maintain the freezing temperature.


Why does my refrigerator have only one thermostat knob?

A lot manufacturers only place one thermostat or temperature knob in the refrigerators than separate ones for the refrigerator and the freezer. It is cheaper this way for a manufacturer and it’s also efficient.

A single thermostat is always placed in the refrigerator section and not the freezer section because refrigerator is where the temperature is most important. It does not matter much for the freezer as long as as food is being frozen.

The amount of coolness going around the whole machine is balanced by splitting the evaporator into two sections. The first and the bigger one controls the freezer section and the second one controls the refrigerator compartment. When the thermostat of the refrigerator compartment senses that it needs more cooling, it switches the compressor on and the cooling is fed to the refrigerator.


What is temperature of deep freezer?

A deep freezer is a just a freezer without a refrigerator with a lot of space and faster freezing processors. It also mechanically freezes the food harder than the usual refrigerator freezer.

Deep freezers keep the food frozen at -18 degree C or 0 degree F, which is general temperature of any freezer. However, deep freezing can expose the food from -30 degree C to -50 degree C. It helps the core of the product reach the freezing temperature of -18 degree C in about 45 minutes to an hour.

Deep freezers commonly provide lower temperatures than refrigerator freezers because it is generally used for preservation of food for a very long term usage.


Is 5C a good number to have my refrigerator set on?

Generally speaking, no. The temperature of 5 degree C can be too high for a common-use refrigerator. However, it really depends on the number of variables stored in a refrigerator.

Milk and other drinks are usually stored 3 to 4 degree C because most people like them just above the freezing point. On the other hand, vegetables and produce require cold and not frozen temperature. The best way to find out whether or not the right temperature is 5 degree C for you is to experience it for a day or two. A good rule of thumb states that the temperature should not be less than 3 to 4 degree C for a crowded refrigerator.


Does a refrigerator stay colder when it is full?

A refrigerator doesn’t work when it is overstuffed as it does when it’s spacey. Secondly, if the refrigerator is being opened too many times and for too long durations, it also affects how the food is stored. The performance decreases. But it does stay colder.

That being said, it wouldn’t work best with being totally empty either. When the food absorbs cold air, it helps cool the food next to it. So, if a refrigerator is almost empty, it is costing you money because the machine would have to work very hard to keep itself cold.

The best way is to fill the space that is provided, but don’t overstuff the refrigerator, and don’t open it too many times without reason.


Why is my refrigerator taking time to freeze?

Stored a packet of ice cream for your guests but it is not frozen properly when the guests arrived – now that’s a problem! Your freezer is taking its time to freeze up things. Why is it happening? There can be multiple reasons.

One, the refrigerant power is set too low. Set it down to lower temperatures, which means turn up the knob.

Two, you are storing your food wrong. If you want your food to freeze up in optimal duration, don’t stack the containers one above another, spread them horizontally. Once the food is frozen, you can stack them and make more space.

Food freezes at 0 degree celsius or lower. Freezers usually begin at -18 degree celsius. With the right methods of storage and the right temperature settings, it should not take more than 2 hours to freeze up your food completely with its container or thick packaging.

If your freezer is still not freezing the food, there might be a problem with the compressor or air vents in the freezer.

What does a refrigerator do if the air outside is below freezing?

Extreme temperatures can actually damage the refrigerator. The oil in the appliance would begin solidifying and would not let the machine perform properly.

If the air outside is below freezing temperature, suppose -40 C, and the refrigerator is set to a normal temperature, be it 4 C, the refrigerator will cool too quickly and compressor will turn off. However, refrigerator are designed to maintain the maximum temperature settings, not minimum, so if the temperatures are lower than freezing, it will also freeze the water in the compressor tray and the oil inside the refrigerator, and the machine will stop working. It is best to turn off the refrigerator in such lower temperatures.

The authorities do not recommend placing a refrigerator in a setting below 10 degree celsius.


Why is my new refrigerator not cooling?

Unwrapped your new refrigerator excitedly and it’s not cooling? That’s a bummer. There are some measures you can take to solve this problem.

First, make sure that you set up your refrigerator as instructed by the manual. Every model of every brand differentiates from one another, so your experience in using refrigerators might not come in handy if you are using a model that operates in an entirely different way temperature-wise.

Second, before you start storing food in, you must wait for at least 24 hours after placing a refrigerator into its spot and turning it on. It would let the refrigerator reach its functionality in order for it to operate properly. It would also let the appliance set its internal temperature. In a day, it will be ready too cool down the food and create first skin of ice.

If you did all this and still don’t know what’s wrong, you can contact the help support and ask for guidance. They might also send a technician who would look at the problem. Usually, refrigerators come with warranty and you would get a replacement if it was indeed a product fault and not yours. If it was your fault in the process and now the refrigerator is not working, you can contact a refrigerator repair service technician and get the problem out of the way.
