Even while everyone needs a refrigerator, not everyone has the space for a huge one. Mini-fridges are the most popular choice for apartments and small homes because of their compact size and portability.

These compact refrigerators can be used as both a refrigerator and a freezer because of their dual cooling and heating systems. It is therefore not unheard of for compact refrigerators to fail to cool. If you are also experiencing this issue, continue reading because we have provided comprehensive solutions.

How to Fix Mini Fridge Not Cooling?

1. Air Vents

Let us enlighten you on the inner workings of a fridge: cold air is blown in through vents. If the air vents are obstructed, cooling will be delayed or prevented entirely. There could be three main causes for air conditioners not to blow cold air.

Pet owners are fully aware of the fur their pets shed. Shut off the refrigerator and check for pet hair in the vents, if necessary. This is a sure bet in one of the most prevalent and overlooked killers. The return to proper operation of air vents is possible after removal of pet hair.

Another thing to think about is whether or not having pets will cause the air vents to become clogged with dust. No matter how meticulously you scrub the vents, the air conditioner will function normally once again after a good cleaning.

Finally, this is feasible if a bowl is placed over the openings leading to the inside. Explore the contents of the fridge and wipe down the interior of the walls. This allows for outside air to be drawn into the compartment through the open vents. It’s good practice to always unplug the refrigerator before giving it a thorough check.

2. Door Seal

To pry open your mini-fridge would need a lot of force, therefore the door seals perform most of the work. The result is that seals on doors are typically so effective at keeping them shut that they can’t be opened by themselves. The cold air inside a refrigerator can only stay there if the door is closed. Therefore, if the door seal is broken, the cool air will not be able to stay in the compartment, and the cooling system would fail.

Since this is the case, it is recommended that a professional replace the door seal. This is because if you choose to conduct the door seal installation yourself, you run the risk of doing a poor job. Investing in a high-quality door seal is crucial, as it plays a major role in both the durability and the protection of the door. Last but not least, the door seal for your refrigerator may only be obtained through the service center of the manufacturer.

3. Look At The Thermostat

If you have tried adjusting the door seal and air vents without results, it is probable that the thermostat is broken. The knob, often known as the thermostat, adjusts the heat or air conditioning in a building so that occupants can remain comfortable. A broken or defective thermostat can be the source of many thermostat-related problems. Keep in mind that such knobs can only be used to adjust the temperature in one way.

The thermostat will not respond to any amount of knob turning. Checking the thermostat for damage or cracks is the best approach to solve this issue. The needle-tip pliers in your toolkit can be used to manually adjust the thermostat if you detect any

The thermostat can be turned to achieve the desired temperature. When the cooling process has begun, it’s best to have a professional replace the knob so you don’t have to use the nose pliers again.

It’s important to remember the settings on the thermostat when thinking about how they might affect the cooling system. Many people do this without meaning to because they forget they turned off the thermostat. If the refrigerator’s control knob is not broken, turning it to a cooler setting will cause the temperature inside to drop.

4. Capacitor

Don’t freak out before we explain what’s wrong because some people call it a start relay. If the capacitor is broken, the compressor won’t turn on.

This means that if the compressor in your fridge doesn’t turn on, your food will spoil. Therefore, make sure everything makes sense (use a multimeter). If there is inconsistency between readings, the capacitor must be replaced. When you replace the capacitor in your mini-fridge, it will start cooling again and you won’t have to worry about the expense because of how cheap it is.

5. Overload Switch

Overload switches perform exactly what their name implies: they cut power and melt down when they get too hot. Compressor temperature plays a role here.

Therefore, this switch will disconnect the compressor if it ever gets too hot. However, a damaged switch will cut power even if the compressor is not overheated. So, if the overload switch isn’t working, make sure it has continuity by testing it and replacing it if necessary. Overload switches can be found at any hardware or electrical store with little effort.

6. Compressor

The lack of a compressor prevents the mini-air fridge’s vents from drawing in any outside air, rendering the appliance ineffective. If the refrigerator is still not cooling, the problem may lie with the compressor. Compressors are easily harmed by low-voltage electricity sources. Thus, consult an expert and arrange for the compressor to be changed. Also, the cooling system can be brought back up to par at cheap expense by replacing a compressor.

7. Power Source

Verify that the line cord is not damaged and that the power cord is plugged in securely. Check that the power switch and outlet are both on. This easy procedure is required for the mini-fridge to work. Unplugging an electrical appliance should only be done with dry hands to prevent accidental electrocution.

8. Thermostat

Just make sure to keep an eye on it and turn it down if it’s not cold enough. Put the lock on the door and wait a while. If it hasn’t started working again after a few hours, come back then. Don’t lose your calm and start pressing buttons; that will only slow things down.

9. Condenser coils

If your fridge isn’t cooling properly, it could be because the condenser coils in the back are dirty. Dust and other particles could build up. A buildup of dust and debris in the coil could be problematic. That is to say, you should aim to clean it at least once every six months.

10. Fans

You’ve done a great job of clearing out the vents. If you’ve exhausted all other options, try turning on the fan and making sure it’s moving enough air. It’s possible you’ll need to replace that part of the fridge, or at least have it professionally repaired. You need to correct this because the refrigerator isn’t cooling properly.

Keep In Mind!

Because it is smaller than a standard refrigerator, it will save at least 12 kilowatts of electricity every hour. However, because mini-fridges need to be on all the time, even the most efficient models still require a significant amount of power. Mini-fridges have several practical uses, including the storage of beverages and cosmetics. But keep in mind that it won’t keep things as cold as a conventional fridge would.

How to Take Care of a Mini Fridge

A mini fridge is useful outside the confines of a college dorm. Extra refrigerators are great for keeping drinks and snacks cold in the game room, in-law apartment, garage, or office. When it comes to keeping food and drinks cold and accessible when you need them, the secondary refrigerator is equally as important as the primary appliance.

  1. Keep your fridge away from windows and any other heat sources like radiators or stoves. If you want to keep your food and ice frozen, you shouldn’t leave your mini-fridge in a garage or unheated area below 60 degrees Fahrenheit because the compressor will run less often.
  2. Put the mini fridge on a level surface to prevent it from tipping over.
  3. If your fridge has a thermostat, turn it to the middle setting when you initially plug it in. Food won’t immediately freeze or thaw at a medium setting; this can be adjusted afterwards.
  4. Make some place in the compact refrigerator for perishables and other necessities. Cold air must continuously circulate through a refrigerator or freezer to preserve perishable items.
  5. Clean the car once a month by wiping it down with a baking soda solution. A mixture of 1 to 2 tablespoons of baking soda and 1 quart of warm water should do the trick. You should clean the shelves and the rest of the surfaces thoroughly. Carefully clean each shelf and the outside of the fridge as you empty it.
  6. Wipe down the outside of the fridge once a week using the cleaning solution specified by the manufacturer. Handprints and stains need to be cleaned up right away.
  7. Every month, you should unplug your refrigerator and clean the dust and debris from the coils and vents. To prevent allergens like dust, dander, and pet hair from reducing the fridge’s efficiency, use the hose attachment to vacuum its coils and air vents.
  8. If you’re leaving for a few weeks, it’s advisable to throw out any food that could go bad. If you are going to be away from home for an extended period of time or if you need to relocate the refrigerator, empty it completely of all food and liquids, clean the interior and outside, and turn off the power. Leave the refrigerator door propped open with a towel under it and inside for at least 24 hours to allow any excess moisture to drip out. Before you leave or relocate the refrigerator, please make sure the towels have been removed.


How do you fix a mini fridge that won’t get cold?

One should use a vacuum to clean the coils located either under or behind the fridge. Filthy coils are a common culprit of subpar cooling performance. Make that the condenser fan is not blocked and is turning freely by checking for debris. Unplug the refrigerator and pull it out of the wall.

Why is my refrigerator running but not cooling?

The failure of a refrigerator to cool is typically due to a problem with the evaporator coil. When evaporator coils freeze up, they stop doing their job. The ice that has accumulated on the coils must be defrosted.

Can a mini fridge be recharged?

However, it is important to remember that many coolants are being phased out of use due to their harmful effects on the environment. Adding refrigerant to your mini-fridge on your own is doable but not advised.

How do I know if my mini fridge is broken?

Wait a few of hours to see how things progress before you call. If your fridge’s compressor never turns back on after turning off and making the familiar humming and vibrating sounds, the problem could be a broken or disconnected thermostat.

Does unplugging a fridge reset it?

Detach the power cord from the wall outlet and pull the refrigerator out of the wall to turn off the electricity. After that, you might hear some whooshing or pounding. That is completely typical. To reset your refrigerator, you must unplug it from power for several minutes.

Why is my fridge warm?

Food in a refrigerator is chilled by air that has been cooled by an evaporator coil. When there are too many items in the fridge, the temperature rises. When your refrigerator is stuffed to the brim, it has a harder time keeping food at an appropriate temperature for storage.


The question, “how to fix a mini-fridge that won’t become cold?” has been resolved. A compact refrigerator is useful in many situations. Just like a regular-sized fridge, this one can break down and stop working. Maintaining a clean and well-inspected fridge is essential to preventing costly breakdowns that necessitate professional repair.
