How Long Do Mini Fridges Last?

How long do mini fridges last

Mini refrigerators have a fairly long lifespan, its good operation time depends on many different factors. If you are curious how long mini fridges can last, this article will answer it for you. In addition, we will give you the factors that affect the life of your refrigerator and when you should replace it with a new fridge.

Refrigerator parts-Which is the most important?

Mini refrigerators are divided into two main parts: the refrigerator frame and the cooling system. These two parts are put together to give the mini fridge perfect structure and proper operation.

Refrigerator frame

Mini fridge frames are parts and details of the mini fridge in the normal state that we can easily see. Precisely, they are the frame, the door, and the compartments and shelves of the mini fridge. The refrigerator frame has the leading role of keeping the internal cooling environment sealed, preserving food, and protecting components and equipment in the refrigeration system.

Cooling system

The cooling system plays the most crucial role in the mini refrigerator structure. The refrigeration system includes components such as compressor, condenser, evaporator, expansion valve, refrigerant. As follows:


Usually, mini refrigerators will have 1 or 2 pistons. Its working mechanism is based on a conversion from rotary motion to reciprocating motion of the piston. The compressor’s job is to suck the liquid-vapor in the indoor unit, balance the appropriate pressure level or push the vapor through the condenser.


The condenser is responsible for exchanging heat between the condensing refrigerant and the cooling medium. The device helps to remove the temperature of the condensing medium from the outside environment. Because of this feature, it is often installed at the ejectors of the compressor and filter dryer before connecting to the capillary. The material used when designing the indoor unit is usually iron or copper for better heat conduction.


The evaporator helps heat exchange between the refrigerant and the medium cooled efficiently. It works according to the heat from the cold environment to supply the refrigerant. The evaporator is installed behind the capillary, throttle, or compressor.


The refrigerant pressure passing through the throttle valve will be adjusted to reduce the temperature to the appropriate level.


Refrigerant is a particular type of liquid solution used in refrigeration systems. It helps create cold temperatures and is very volatile at about minus 32 degrees Celsius.

Factors affecting the life and durability of the mini fridges

Condenser coils are dusty

When using a mini refrigerator, you need to remember to clean the condenser coils at least every six months periodically.

If not cleaned, these coils will quickly absorb dirt and accumulate more and more over time, making the refrigerator lose its cooling effect, which in the long run will cause the fridge to be damaged.

Therefore, you should clean it regularly using a duster and hose attachment on the vacuum cleaner to avoid unwanted situations.

The condenser coils are located under the refrigerator, behind the plate or tray. In some models of mini fridges, they may be found at the back of the appliance.

The fridge door seals are dirty or damaged

The seals on the refrigerator door are the part that keeps cold air from escaping. They also accumulate dirt and reduce their ability to perform their duties. Therefore, users need to pay attention to cleaning the mini fridge door seals with warm water or soap.

You regularly pay attention to whether your mini refrigerator door gasket is torn or broken or not to replace it in time. Alternatively, you can use vaseline to lubricate them, prevent tearing, and keep them elastic and flexible.

The vents are dirty

The vents inside the mini fridge have a role in helping circulate cold air evenly throughout the device. When using a mini refrigerator, these vents are prone to get stuck in food, liquid, or even dirt inside, affecting the ability to distribute cool air evenly inside the refrigerator.

You should regularly check these vents and use a warm wet cloth to wipe when detecting blockages to avoid prolonged problems leading to damage to the mini refrigerator.

The mini fridge is not leveled and doesn’t have enough space

Suppose the place where you place the refrigerator has an unstable surface. In that case, the internal components of the mini refrigerator are accessible to strain and damage, resulting in a shortened service life. Pay attention to adjusting the legs of the mini fridge until it is entirely flat.

Don’t forget to give your mini fridge enough space to avoid impacting the internal components. In particular, do not place heavy objects on top of the mini fridge.

If your fridge is always loud, it’s possible that motor is being overworked. The motor helps to regulate the internal temperature of the fridge. It can make noise when it’s running. But it’s not necessary to constantly run at full speed. When the refrigerator’s motor is running non-stop, it may be due to a layer of snow forming, so you will need to defrost by emptying the refrigerator and opening the door.

After fixing, if the motor does not stop running, the fridge should be checked as it may have problem.

Which will cost more, replacing or repairing?

You should compare the cost. After getting the information, you can make the right decision. Search for cost of repairing the old fridge and the cost of a new fridge which is trendy, meet your needs. If the cost of repairing is more than 50% of the cost of a new fridge, consider replacing the fridge.

Tips to increase the lifespan of a mini fridge

To use a fridge effectively as well as increase its lifespan and save electricity, you need to note the following things.

For a newly bought refrigerator

You should let it rest for 2 hours before plugging. Because the fridge has traveled a long distance, it is easy to cause an electric shock if you plug it in and use it right away. Also, limit moving the new refrigerator. The surface of the refrigerator must be firm and flat so that the refrigerator is stable during use.

Do not put food or anything in the fridge immediately. If the fridge is suddenly overloaded to cool a large amount of food, it can be damaged. And your food will be affected by smell from plastic inside the fridge.

Place the refrigerator in a well-ventilated place, away from heat sources

Make sure to put your refrigerator in a place which is away from heat sources, away from direct sunlight or next to other heat and light generating devices. The refrigerator placed in an area with high temperature cannot operate smoothly. At the same time, the motor has to work too hard to cool the inside, which greatly affects the life of the device.

Use a separate power supply for the refrigerator

The power source is an important factor that makes the fridge to operate efficiently and avoid damage due to unstable electricity. The correct use of the power source also helps to protect the electrical system, avoiding fire and explosion caused by electrical short.

Practice good habits

Regular cleaning

You should clean the refrigerator properly every week to remove the stains, potential bacteria inside and outside the fridge.

When cleaning, you should turn off the power and take out all the food. Then, use a soft cloth to gently wipe the inside of the refrigerator. Avoid using any sharp object to scrape, pry snow and dirt in the refrigerator so as not to damage the indoor unit.

Limit opening the refrigerator for too long

You may have a habit of opening the refrigerator, drinking water or enjoying food for e few minutes. However, this action will allow warm air from outside to enter the refrigerator, thereby affecting the cooling ability, the refrigerator has to work harder than usual to ensure the temperature at the right level.

Keep food sealed and covered in the refrigerator

Users often have the habit of keeping leftovers in the refrigerator. It seems simple, but if you don’t properly store it, your food is very easy to spoil. It also affects the lifespan of the fridge.

Although filling up with food will make the refrigerator work harder, the reverse is not necessarily true. The cold temperature in the refrigerator depends largely on the amount of food you store; cold foods will actually help each other keep cold better.

If you don’t have much food to store, add more water bottles to fill up the wasted space in the refrigerator.

To sum up

Mini fridges are becoming more and more useful. Although the average lifespan of a mini fridge is about 6-14 years, the way we use and store it will determine whether the refrigerator will last long or deteriorate quickly.
