Why the freezer is hot, what to do
You feel that the walls of the freezer are hot? It is possible as long as the compressor continues to work. But, when the engine is resting, the walls should cool down. If this does not happen, you need to look for the reasons why the freezer is heating.
The original design of the refrigerator was to have the freezer compartment on top. Modern models have one on the bottom. This is a more rational approach because the compressor first blows the cold into the freezer and then into the refrigerator.
Since its task is to cool the food, it seems that the walls should also be cold. But that’s not true. To better understand why they heat up, you need to understand the general principle of operation.
Thanks to the compressor, the refrigerant circulates through the system, absorbs the heat and thereby cools the chambers. The accumulated heat is led out through the grill, which used to be located on the rear wall.
Now these tubes are located inside the cabinet, on the sides and on the top. So don’t be surprised if it gets hot between the fridge and the freezer.

If the walls warm only slightly and cool down during the “rest” of the motor, then you don’t have to worry. The manual specifies the temperature class of the appliance: at what temperature it should be operated.
But if the chamber heats up constantly and the temperature is clearly above the norm. this indicates a malfunction.
Trivial reasons you didn’t know about
Sometimes too much heat on the side walls doesn’t mean it’s broken. There are some simple causes that can be identified and quickly corrected (if necessary). And also to avoid heating of the refrigerator sides in future.
The warmer it is in the room where your refrigerator is, the more difficult it is to keep the chambers cold. The speed and frequency at which the compressor turns on depends on the temperature difference between the inside of the compressor and the outside.
The more often and faster the compressor runs, the more the heat exchanger heats up. It transmits heat to the walls, heating them. Accordingly, if it is hot in the kitchen, the walls will heat up more. Also, if the outside temperature is high, they are less likely to cool.
If you come back from the store and start putting food in the refrigerator, the temperature in the chambers will rise significantly. The compressor will have to operate at an increased capacity. As in the previous case, this will lead to more heat on the heat exchanger radiator and the walls, respectively.
You categorically should not fill the fridge in such a way.
Hot in the chamber
Some people have a habit of putting hot food in the refrigerator. This will have regrettable consequences. A pot of hot soup greatly increases the temperature inside the chamber. The appliance has to work at an increased load.
As a result, overheating of the heat exchanger and side walls. Yes and other negative consequences can be. We talked more about them in the publication: Why you should not put hot food in the fridge.
Many models have a super-freezing function. It can also be labeled as:
When the function is activated, it cools the food in the freezer or refrigerator at a high rate. This increases the power consumption of the refrigerator, the intensity of its work. Due to this the side walls start to heat up strongly.
If the function has no automatic shutdown, and you forgot to turn it off, then you understand why the refrigerator has hot sides. When this function is activated, check if it is working. If the mode does not turn off automatically, it’s time to find a refrigeration repairman.
The compressor gets hot
If the compressor is always very hot, it may be caused by overloading. It is necessary to free them from the products a little, otherwise there is a risk that the device will finally break down. It is also often associated with the fact that in the chambers often put warm food, which is strictly forbidden: because of this, condensation forms inside. In addition, the doors should not be left open for a long time. Other causes could be a refrigerant leak, a malfunctioning heat exchanger or wear and tear on the electric motor due to the “age” of the unit.
The partition should warm up a little. this is important, because the temperature in different chambers is different. But because of the failure of the heater, it often becomes very hot, which is not the norm.
Such a problem also arises because the rubber bands on the doors of the two-chamber refrigerator do not fit tightly enough.
The cause of strong heating of the sides and back of the refrigerator may be its improper location. According to technical standards, the distance from them to the walls of the room and furniture should be at least 10 cm. If the device is built in, then to the upper shelf should be more than 20 cm. Although for some models there may be other requirements.

If the gaps are smaller. there will be problems with air circulation. It will stagnate, so the heat exchangers can’t give off heat quickly. Freon will heat up, transferring heat energy to the walls.
Another side effect of improperly installed refrigerators is rapid compressor wear and tear. To maintain a normal temperature in the chambers, it will start to run at a higher speed, turning on more often. This will lead to a reduction in its service life and failure.
High motor temperature
To get your freezer up to 20°C, the motor has to compress freon at high pressure. The compressed gas gives up some of its heat to the compressor and the rest stays in the condenser. The motor gets heat from the electricity flowing through its windings. A temperature of 50-60 °C should not be a concern, and the maximum limit can be as high as 90 °C. The older the compressor, the hotter it gets, and this must be taken into consideration.
Important! Never check the temperature of the motor with your hand. there is a risk of burns.
When the motor heats up to the point that the protective relay is triggered, then you can not exclude the intercircuit closure and even damage to the winding of the motor. in this case you will need to replace the node. But before ordering a new compressor, call in an experienced technician to diagnose the equipment. Good luck!
When it is necessary to call the master
The third block of causes of overheating is associated with the breakage of one or another part of the appliance.
- Door sealing rubber strips are worn out and letting the air in. Their replacement is required.
- There is a refrigerant leak. It is necessary to find the damaged area, seal it and recharge the system with freon.
- The temperature sensor of one of the chambers that registers the temperature and either starts or stops the compressor is broken and needs to be replaced.
If there is nothing wrong with the walls, but the refrigerator compressor is very hot. most likely it is a short circuit or severe wear and tear, due to which it can not work properly. Usually it is necessary to replace the broken compressor.
Under no circumstances should you try to repair these faults yourself. Contact an authorized Midea service center. A specialist will figure out why the wall of the refrigerator is heating up, and will repair the device quickly and qualitatively. But the attempts to cope with their own forces are fraught with even more serious damage and a sharp increase in the cost of repair.
Why the walls of the refrigerator or the grill are heated. possible causes of the hot compressor and ways to fix the breakdowns
It is difficult to imagine a household without such a useful and necessary device, as a refrigerator. Minor downtime, even for a few hours, can cause food to spoil.

That’s why people often listen to the work of equipment, check its condition and at the slightest malfunction try to identify the cause and try to prevent a more complicated breakdown. Today we will talk about such a widespread problem, as the refrigerator is heating up.
Is this normal?? When to look for faults and what to do first? First of all do not panic, it is necessary to determine what exactly in your refrigerator is heating, in what part. A lot depends on it.
Why is the refrigerator (grill) warm in the back? When you need a handyman?
The back wall is always warm, due to the way the refrigerator works. But if the grill is not just hot, but hot (t over 45 ° C), it is a cause for concern.
You must check the grille for dirt. Dust and cinders hamper the heat emission that in its turn reduces the fridge efficiency. You should clean it. To do this, you must unplug the appliance, move it away from the wall and vacuum the grill or remove deposits with a brush. At that be careful not to damage the fragile tubes of condenser.
If that didn’t help, you should check the condition of the temperature sensor. It may be that it is set to its maximum position, resulting in an increased load. As a result of the increased heat output, the temperature of the grill is naturally higher.
Ambient temperature should not be discounted. In hot summer at 30 °C and above, heat transfer becomes difficult, putting a heavy load on the compressor.
If all of the above situations do not help to fix the problem, you need to call a master for a complete diagnosis.
The refrigerator heats but does not freeze
The motor heats up in both the defective and malfunctioning refrigerators. You don’t have to sound the alarm as long as the chambers are at the right temperature. If the products disappear or, on the contrary, are overfrozen, or gauges beep, alarm indicators work. it is worth to pay attention and listen to the work of the refrigerator.
If the engine warms up but does not freeze, there may be several reasons:
- Refrigerant leakage;
- The capillary system or the filter-dryer is clogged;
- broken temperature sensor;
- Disruption of heat output from the walls in rooms with high humidity and temperature.
If the circuit starts to bleed gas, the compressor runs continuously compressing air without interruption. Naturally, in this situation the answer to a question, why the refrigerator compressor warms up very strongly, is obvious. The motor is so hot that you can burn yourself if you touch it and it is giving its heat into the room. The evaporator becomes warm.
Here is the answer to the question: why the refrigerator does not freeze, but with its work it can replace the full-fledged radiator of heating. Of course this is a joke. To use the refrigerator in such capacity would be strange, to say the least. If one needs heating of a premise, it is possible to consider a variant with the conditioner working in a cooling and heating mode as an alternative.
If the engine fails to start. the compressor is the cause. Most likely, there was an interwinding short circuit or a short circuit. As a result, the engine is warm, but will not start. You can hear the clicks of the starting protection relay. In fact, in this state, the fridge does not work at all. The unit will need to be replaced, which, however, is associated with serious monetary costs.
If there is a clog in the capillary tube, the freezer will be warm. Sign of breakage. only the first knee of the condenser grid is hot, and the rest of the assembly is cold.
Failure of electronics or breakage of temperature sensor can stop compressor from starting. In both cases, the assembly will not receive a start command:
- Broken ECU does not give the control signal;
- Broken temperature sensor incorrectly tells ECU that temperature in chambers is normal, accordingly ECU does not give a signal.
Causes that are not breakdowns, but lead to an increase in the temperature in the chambers:
- There is a lot of food loaded into the fridge at once.
- There are pans with hot liquids in the chambers.
- The refrigerator has not been defrosted for a long time.
- Refrigerator doors open too often.
No need to put hot foods in the refrigerator
Certainly it is not allowed to do everything that is listed above, if the purpose is to prolong service life of the refrigerator.
Causes listed in the first list are not critical and can be easily eliminated. If the refrigerator stands near the heating appliances, you can find a new place for it and the problem will be eliminated. But it is not possible to correct technical breakages independently. the qualified expert is necessary here. In most cases, such a malfunction as constantly hot sides of the refrigerator are eliminated by the technician on the spot. But before his coming you should prepare the unit for repair. take out all the products, disconnect from the power supply, let it defrost with the doors open, and then thoroughly wash it from the inside. You should also ensure that the repairman has unobstructed access to the refrigerator from all sides, including the back wall.
Important: if you have found the instructions on the Internet to repair your refrigerator model, do not try to translate the theory into practice on your own! Without the proper experience and knowledge, you risk your health.
