How does the refrigerator work?

A refrigerator works using a compressor plugged into the wall socket and runs continuously like all refrigerators. An interposed temperature controller turns the motor on and off as needed. So the fridge cools whenever the engine is running.

Why does the refrigeration stop working?

Every refrigerator has a compressor supply with electricity. The temperature controller ensures that the compressor starts up when needed and moves the coolant: the inside of the refrigerator cools down.

If the cooling no longer works, one of these technical components is probably defective. In most cases, the thermostat detects and regulates the temperature prevailing in the refrigerator.

Refrigerator does not cool: Causes and Remedies.

If a refrigerator cools too much or too little, it may be due to the thermostat, and we may set the thermostat incorrectly. 

So put the temperature selector switch correctly by turning it. Then check the setting by placing a glass of water with a thermometer in the refrigerator for a few hours. The ideal temperature should be between 2 and 6°C. 

Sometimes only the thermostat can defect. The unit will not turn on when it needs to cool, even on the correct setup. If trying to fix the thermostat precisely does nothing, you should replace it.

Now let us look below at the causes and possible remedies.

1. The walls are getting covered with a thick layer of ice.

If the refrigerator’s interior walls cover thick ice, the unit will not cool well.

In this case, the ice layer has an insulating effect and prevents the device from working optimally. Solve this problem by defrosting the refrigerator regularly.

2. The condenser is clogged.

Possibly, the unit cannot cool appropriately because the condenser covers dust. The condenser is the grid-like structure on the back of the unit.

Due to dust accumulation, it cannot dissipate the heat adequately, so the compressor has to run longer than usual.

Therefore, check if the grille on the back is suitable and clean it regularly to maintain your refrigerator’s performance.

3. The fan is getting broken.

The condenser is equipped with a fan that promotes heat exchange in certain refrigerators, ensuring that heat is distributed more efficiently.

If the fan stops working or is covered with dust, for example, the refrigerator will not be able to cool properly. If you notice that the fan is defective, you must replace it.

4. The appliance no longer closes.

If the refrigerator no longer closes tightly, it can no longer cool sufficiently. Check if the door seal is cracked, deformed, or damaged.

If so, you will need to replace it or reinsert it properly. If the door seal is acceptable but still does not seal, the door itself may be defective.

Unfortunately, if it is bent and the air can get in, you will have to replace it. Finally, check to see if food is preventing the door from closing.

A thick layer of ice can also cause the door to stop closing. Therefore, do not forget to defrost your unit regularly.

5. The room temperature is too high.

If the room where the refrigerator is located is hot, the fridge cannot cool optimally. Therefore, check if the unit is next to a heat source, such as a radiator or an oven.

It is also possible that the sun is shining on the refrigerator from outside. In this case, move your unit to a place where external heat will not affect it.

6. The cooling circuit loses cooling liquid.

Without cooling fluid, the refrigerator cannot produce cold, and a leak in the system can cause the unit not to cool enough.

Such a problem can only be fixed by a professional. Therefore, contact a service technician who will find the leak, repair it, and refill the coolant.

FAQ Refrigerator Does Not Cool

What to do if the refrigerator does not cool properly?

If the refrigerator no longer cools sufficiently, you should remove the contents from storage so that the food does not suffer from the unaccustomed heat. Initially, cool boxes or bags are sufficient for this purpose.

How to notice that the refrigerator is broken?

Many devices strike meanwhile, however, already after five years. If a device is defective, a new purchase is worthwhile, and the investment is usually not much more expensive than a costly repair. The recommendation to replace the refrigerator after 10 to 15 years is mainly energy consumption.

How long does it take for a refrigerator to cool?

As mentioned initially, the time it takes for a refrigerator to be ready for use can vary. However, it can be narrowed down to 4 to 6 hours as a rule.

Why is my freezer no longer cooling correctly?

If your freezer doesn’t cool anymore, it could be because the device doesn’t detect the temperature accurately. A thermostat with a temperature sensor is responsible for this – just like a radiator, it may be incorrectly set or even defective.

Why does the refrigerator no longer work?

Your refrigerator’s plug is possibly not plugged in, or the socket is not getting supplied with power. Fill another device into the same outlet to check if it usually works. Also, check the power cord. If it is damaged, you will need to replace it.

What to do if the refrigerator is broken?

If the appliance is broken, many problems do not require you to call a repair service or buy a new one directly. In the refrigerator, you store a lot of food, which otherwise quickly goes wrong. If the device breaks, it must be rapidly repaired or replaced.

How long does a refrigerator take after it is turned on?

About 4 hours if it is a modern device. It takes about 4-6 hours, and if you move it, you must turn it on only after 9 hours; otherwise, it will break.

How long should I leave the refrigerator after delivery?

If you transported your refrigerator down, you should wait at least twelve hours before starting it again. For older refrigerators, even 24 hours is getting recommended.

Why is my new refrigerator humming?

Possible cause of humming: leaking refrigerator door. If the refrigerator no longer closes properly because, for example, the sealing rubber has become old and porous, heat will penetrate the refrigerator’s interior. Put a flashlight inside your refrigerator and close the door.

What level should you set the refrigerator?

The optimal refrigerator temperature is between 5 °C and 7 °C. Usually, this corresponds to level 1 or 2 on models with knobs to adjust the temperature. During the summer months, feel free to turn the dial to level 3 to 5 to counteract the heat from outside.


When the refrigerator no longer cools, we should take action quickly.

The first thing to do is determine the possible cause based on the signs. However, it is usually necessary to hire a specialist for the repair work.

Especially in the case of older refrigerators, you should consider whether purchasing a new device is not cheaper than repairing it.

In addition, the modern appliances of refrigeration technology are often much more energy efficient.
