What to do if the refrigerator with No Frost does not freeze or is weakly cold?
Think like a male club copyright what to do if the refrigerator with No Frost does not freeze or is weakly cold?
Is it possible to independently repair the refrigerator No Frost? Of course, if there are at least a little knowledge of physics.
So, a few weeks ago, the great and reliable refrigerator Whirlpool ARC 8140 with the No Frost system began to freeze badly. The freezer camera stopped cold, yes, and at first there was a strange noise similar to the sound of a broken fan. Then the noise disappeared and it became clear that the great refrigerator Virpool does not freeze at all.
If you have the same problem, then do not write off the compressor to mourn or something else, most likely the reason why the refrigerator with the know does not freeze this:
The error of the amateur
Often we ourselves are the reason for the misunderstanding why the refrigerator does not turn off or often turns on and rarely turns off. We ourselves, not wanting it, we operate the unit incorrectly, making the simplest mistakes. For example:
- The free.cooling mode or Super Freeze mode is included in the freezer. Options for managing these modes. manual and/or automatic. The electronics should turn off the compressor after 8 hours, and manual control. it is manual: you can forget, and then the refrigerator will work until you yourself turn it off;
- Summer heat. no reason to set low temperatures in all cameras. The refrigerator is assembled like a sealed device, and constructively can withstand a large temperature difference. But the wider the temperature spread inside and outside, the less often the thermallane will turn off the load;
- Do not place too hot food in any department. Hot items will heat it, and the supercharger, respectively, will work even more intensively and less often disconnect.
- The standard temperature regime recommended by manufacturers in the main refrigerator should not exceed 4 ° C, in the freezer the temperature should be held about about about.18 ° C and below (-20 ° C-22 ° C). In summer, it is recommended to set the temperature at 2 ° C-5 ° C.
Examination of the seal
Sealing gasket in modern refrigerators is made of soft magnetic rubber so that the material fit tightly along the entire perimeter of the door. If the rubber of the gasket has cracked or broke, it will not work to repair it. you need to buy a new seal.
If there is a gap, the compressor can work constantly, but the cold will go through the gap, and there will be no fright of the unit at the proper level. Do not go to cheap offers, it is better to buy an original gasket that will definitely last much longer than a fake.
The increased and unnatural rigidity of the seal can come from old age or from contact with cleaning means. Replacement is not obligatory. you can try to return the plasticity with rubber homework. This can be faster and cheaper than contacting the service center. After dismantling the seal, do the following: warm the rubber with hot water for 15-30 minutes.
To remove the seal and not damage it, first find out how it is fixed. Often it is fixed on glue or special mounting foam, and then it can simply be torn without damage. The second case is the fastening of rivets or other types of metizes. The dismantling method should be selected on the spot. cut the rivets, cut them down with a chisel or cut off a corner grinder.
The cold disappeared in the refrigerator. Drip defrust system
In refrigerators with a crying system, this is mainly due to a leakage of freon or a clogged caplicity. Sometimes it happens that the thermostat works incorrectly, that is, the compressor is very rarely turned on, in cold.controlled colds, the role of the thermostat, the termistor, which changes its resistance, with an increase or lowering temperature, performs. To check the thermostat, you need to get to it and close the contacts that are suitable for it, if you see a green wire with a yellow strip or a yellow wire with a green strip, then remove it to the side, this is a ground wire, the remaining wires can be shifted, so It is checked by the thermallela not only in the crying system but also on the know.free. By jaming the contacts, we turn on the engine directly, that is, we check its performance, as well as draw conclusions on the thermostat, if the engine starts and began to work, then it means it whole, and the thermostat must be changed.
I draw your attention to the fact that in this way, we can start the operation of the engine and the refrigerator, no more than 2 hours, after this time, it is necessary to measure the temperature in the refrigerator, there should be about 5-6 degrees of heat, if there is no such temperature to be observed. then we must look for another reason, most likely related to leakage. In refrigerators with electronic administrations, it is often a breakdown of the heater and the thawing sensor and therefore a lot of questions are asked. I will try to answer one of them
I have a LG refrigerator, water flows down the back wall in the refrigerator, or rather drained. Now the refrigerator does not work, or rather, they work but only 6-8 hours, then it costs. I have to constantly turn it out of the outlet, and then turn it on, this process has already taken me out. The display shows a normal temperature, although the cold disappears almost to the end in the refrigerator chamber, in the freezer is held at the expense of products. What can be the reason and what to do
Such a malfunction can be eliminated only by the master that has certain skills. Most likely you have a refrigerator with a crying system thawing and with electronic control. In these colds, on a weeping evaporator, there is a touch sensor and a heating heater, on the “photo 1”, which is located at the very beginning of the article, you can see how to get to these details. Here you must understand that you have to cut off the corner grinder, the iron back wall of the refrigerator housing, then pick out the foam and only then, you can replace the thawing sensor or the heating heater. Check these spare parts, you can on the control unit, the wires from the heater and the sensor are suitable for it. The heating element is checked by ordinary phrase, and the sensor by change in resistance, at room temperature, the sensor resistance is 13 kOhm
How to check the fan and why there is no voltage on it
To begin with, let’s decide what is responsible for the fan operation on No Frost and how this part is included in general. The first thing you should understand for yourself is that 220 volts are submitted to this part and to check it, it is enough to submit 220 on it and see if the fan will work or not. If the launch does not occur, then it is necessary to check those nodes that guide this spare part. There are only 3 details in such units that are responsible for supplying voltage to this node
- The inclusion and shutdown button. It often happens that this button is burning out, especially for LG No Frost refrigerators, which have a timer and a thermostat, that is, with mechanical control. On refrigerators with electronic control, everything is a little different, I will talk about this in the next paragraph
- Relay on the control unit → This item more applies to LG No Frost, which have electronic control. In general, there are rumors on the control unit that leads the operation of the fan and the motor, they sometimes fail. In this case, the fan button is led by the fan and the relay on the control module. The button in such units is usually located between two cameras and it opens and closes with a magnet, which is located on the door of the refrigerator
- The temperature sensor of the evaporator → This item also more applies to electronic control. As long as there will be no signal on the brains from the touch sensor or the temperature sensor of the evaporator that the desired temperature for turning on the fan appeared on the walls of the freezer. the control unit will not give voltage to the windbreaks
Well, now let’s look at the questions that most often sound on my channel and concern the voltage, that is, why 220 volts do not enter the fan
I have an old LG Nou Frost, I worked faithfully for more than 10 years, and recently the fan has poorly turned on. It happens that it stops in the process of work, that is, the refrigerator works, the motor is buzzing, and the impeller does not spin. If you open the door to the refrigerator, and then close it → The fan turns on. What could be the reason
I have already called the reason above, most likely button for turning on light came out, you need to replace it. Please note that it is not simple, this button works in both directions, that is, it does not have two contacts, but four. One pair of contacts turns on the light and the other pair turns on the fan. When you close the door, the button switches the flow of current from the bulb to the fan
Please tell me how the fan should work, for some reason it is constantly noisy for me, even when the compressor does not work, sometimes it happens that it turns off, but this happens very rarely. Do he really have to constantly oil. I have a LG refrigerator with electronic control
The culprit of this behavior, there may be a relay on the control module, sometimes it stupids stupidly, the freezer temperature sensor could also cover, there is 50 to 50, either a sensor or a relay. On refrigerators with electronic control, the fan turns off a few seconds after the engine is turned off. The signal for disconnecting gives the temperature sensor of the evaporator, it must show the control module that the temperature of the freezer and in the freezer is about the same. After turning on the engine, the fan does not immediately start, again, it will begin to work only when the temperature sensor of the evaporator will show that the minimum value of the cold is reached on the freezer. In principle, I talked about all the most basic breakdowns associated with the operation of the fan, I think this will facilitate the task of repairing the refrigerator El Ji No Frost with your own hands, the main thing is to make the correct diagnosis of breakdown, if you find the reason to eliminate it even to a simple layman
LG refrigerator problems with the No Frost system
Consider typical malfunctions for Elji brand models. Decide which camera has stopped working in the refrigerator.
Noticed that the products began to deteriorate? It’s not about the expired shelf life, but in the work of the refrigerator. In addition, another camera works “for two”, experiencing increased load. Therefore, nodes and details wear out faster.
Perhaps it’s not a breakdown. Perform verification:
- Camera doors. How tightly it is closed. If the door is not closing poorly, look if something is in the way. Inspect the rubber seal. it must tightly fit the body. In case of damage or severe pollution of the seal, you need to replace.
- Fan in the department. Clushing cold fan is locked. His blades are overgrown with snow and ice. So, you need to urgently defrost the refrigerator. at least for a day.
The fan rotates normally, the door is closed, but there is no cold? There was probably a breakdown:
- If the compressor operates no more than 5 seconds, and an oily puddle has formed under the refrigerator. the case is in the motor. Need diagnostics to set the condition of the motor-compressor. Its repair or replacement is possible.
- When leaking gas-freon, there are also problems with cooling. The causes of leakage are different to determine them, it is necessary to distinguish between “symptoms” of a problem. For example, bloating of the wall indicates a leak in the inside of the refrigerator. Will have to disassemble and repair the evaporator. Rusty smudges in the freezer are indicated by leakage through a steel circuit. You will need the intervention of the master. With mechanical damage to the wall of the case (if you “help” the refrigerator to defrost) will also have to restore tightness.
That it does not work in the refrigerator No Frost
What to do if the refrigerator No Frost is constantly working and does not turn off? Sort out the reasons for this behavior.
The refrigerator does not turn off
Periodically the motor should turn off. The continuous operation of the compressor leads to the wear of its components. Therefore, the first thing you have to check:
- The door of the camera. Is it tightly closed? Maybe something interferes with her or the seal needs to be replaced. The problems with the closure of the door are solved immediately, otherwise warm air will constantly penetrate the department. Why the motor does not turn off.
- Established modes. If the supermechanical control regimen regime on electromechanical control, then it will not turn off until you turn the regulator.
- The presence of ventilation. If the room is stuffy, or the refrigerator stands close to the wall, the battery, the compressor will constantly escalate the cold.
You have checked everything and even replaced the seal, but the motor continues to work? Perhaps there was a breakdown:
- The temperature sensor gives incorrect readings to the module, or the thermostat has broken. These reasons lead to the fact that the electronic board receives irregular signals, so cooling in the cells does not turn off.
- The control module burned. The reason is the faulty board or its elements. it is impossible to trust it with the operation of the equipment, you need to diagnose and replace it.
- Problems with the evaporator. Probably, a blockage of the capillary tube occurred. It is necessary to call a master who will examine and eliminate the blockage.
- A gase-frane leak occurred in the system. He is responsible for cooling, so the refrigerator tries to compensate for the loss of the refrigerant by constant work.
- Problems with a compressor that cannot create normal pressure for cooling.
If you notice such a problem, contact the service center. No need to wait until the technique finally fails. Such malfunctions happen to the refrigerators of the NOU Frost “Stinol”, “Atlant”, “Virpul”, “Daewoo” and others.
LG single door inverter (Refrigerator) fridge not cooling problem
In the refrigerator know Frost, the fan does not work
The fan is a mandatory element in the system. Without it, cold air will not be able to get into the compartment and cool the products. Two problems happen to the fan: either it does not work, or it constantly works. Consider both signs in more detail.
The fan has stopped working
Most often this happens when the part of the part is freezed. Open the camera door and look. if the blades are overgrown with a layer of ice and snow, you need to urgently defrost the refrigerator. Perhaps there was a refrigerant’s exit or a drainage hole was clogged, where thawed water flows.
Defrosting needs to be performed for at least 10 hours, better. a day.
If even after defrosting the fan did not start working, check its motor for serviceability. When combustion, the part must be completely changed.
The fan is constantly working
When the blades rotate without stopping, the reason may be in the evaporator that is overgrown with ice. The air begins to circulate poorly, so the fan works to lower the temperature in the chamber.
Similar signs can indicate a breakdown of the compressor, control module, temperature sensor. In case of malfunction of the latter, the fee receives incorrect information about the temperature in the chamber, so it makes the engine work without stopping. In such cases, a complete diagnosis of the refrigerator is needed.
Why a lot of ice on the freezer evaporator LG Nou Frost
There may be several reasons for this ailment, but first of all you need to check the tennie, which is located on the freezer evaporator. You can check it using a multimeter and ordinary phon, the resistance of the heating element can be different and honestly, I almost never pay attention to it, it is important for me that the spiral is not in the cliff
Recently, my refrigerator LG No Frost (the freezer is at the top), stopped turning off. As it should, I dismantled the freezer and found a large cluster of ice, and Ten’s test showed its malfunction, he did not call. I work as an electrician and it seems to me that I can change it, but by walking on the Internet, I have never seen a rack anywhere for my model. I have such a question whether it is possible to replace any other heating water, because, as I understand it, the main thing is that it warms up the evaporator, that is, that the condensate flows into the channel for drainage of water
The main thing is that it is suitable for fasteners, that is, I sat in those nests where the old one stood. In power, they are almost all the same, I never pay attention to it. As for the wires, they can always be redone. In the video below, I explained in an accessible way how to replace the heating teti. True, the Samsung refrigerator was taken as an example, but this is not global, the heating element in such units changes the same way
Watch the video how to change the heating tick on the refrigerator know Frost
As you can see in the replacement of the heating element, although there are difficulties, but still you can do such a job with your own hands, it will come out much cheaper. The main thing here is to understand that only two wires are suitable for Ten himself, and the rest of the wiring goes to the fuse and to the control module. This video shows how I converted the wires, from one model to another
How to check the temperature sensors and tickles on the refrigerator LG know Frost
I already wrote above that there are two control systems in such units. On refrigerators with mechanical control, the thawing sensor performs the thermostat, and thermoresistors are installed on the refrigerators with electronic control or as thermistors are also called. The main property of the termistor, change your resistance when the temperature decreases or increased. I have chosen several questions thanks to which I will try to reveal this topic
LG DOUBLE DOOR FRIDGE COOLING PROBLEMS
Hello, a refrigerator does not work on my refrigerator, after opening the front cover in front of the evaporator, I found that the freezer is completely in the ice. I was recommended to replace the thawing sensor and check the heater. I checked the heater without difficulty, but with the sensor, I will not think a little. Where he is and how he looks, I found two sensors in one silicone packaging. I wanted to call them, but neither in Omma nor on megaoms they do not call. I have a refrigerator with electronic control, that is, I set the temperature with buttons
Photo of the LG No Frost refrigerator sensor
Yes, indeed, in one silicone package there are two sensors. One of them is a fuse, its resistance is almost zero, but the other (white), this is the thawing sensor, its resistance at room temperature is 13 kOhm
I ask for help in repairing the refrigerator LG No Frost. The very problem is that ice is constantly accumulating on the evaporator, I defrost every two to three weeks, depending on the time of year. Tenn checked, like a whole, in any case, the spiral itself is not in the cliff. I can’t check the touch sensor, or rather I don’t know its resistance, at room temperature it shows 6 kOhm, if it is heated, then the value remains the same. Is it right or not?
At room temperature, the resistance of the touch sensor should be about 13 kOhm, with an increase or decrease in temperature, the resistance should change. Judging by what you wrote, the sensor is not worthless
I was already tortured with my skiing, I constantly defrost. The refrigerator is old, the temperature is set by the thermostat, the whole problem is that a month after deep defrosting, the refrigerator chamber stops working again and not only the engine itself does not turn off on the refrigerator. In general, you have to defrost again for 2-3 days and only then does it start working normally
As I understand it, you have a LG refrigerator with a mechanical control system. To cope with your misfortune, it is advisable to change all the mechanics, that is, the sensor of the latch and the clock mechanism. Believe me, as an experienced master, replacing one of these details may not give the desired result. The fact is that each spare part has its own resource, in your case, they worked out this resource. Do not listen to those who will advise you to change everything separately, it is better to do everything at once and for sure. In the photo below, you can see a timer and a touch sensor

The refrigerator began to freely freeze. what to do. useful tips and life hacks
Over time, any, even the highest quality household appliances can fail. The refrigerator is no exception. And the breakdown can be different. In this article, we are talking about the one in which the device works, the compressor is buzzing, but the temperature in the chambers does not decrease. What to do in this case?
Noticing that the refrigerator is poorly freezing, it is necessary to conduct its initial diagnosis. She passes in three stages.
Connection to the network
First of all, you need to make sure that the device is connected to the network. It is better if the connection is direct, without the use of extension cords.
Closing the door
Then you should check whether the refrigerator is installed, whether the surface on which it stands. You also need to check whether the door is closely closed: are there any objects that prevent you from closing.
It is possible that the device stopped freezing simply because someone accidentally pressed the “defrosting” button. Therefore, in the initial diagnosis, you should make sure that the device works in normal mode.
If the diagnosis described above did not help determine what caused the refrigerator “refuses” to freeze products, then you should proceed to a more serious examination of the device. The high probability that the problem can be eliminated independently, without seeking help from professionals, still remains.
First you need to check the condition of the rubber seal on the door. If it has worn out, then the warm air from the room will penetrate into the chamber, as a result of which the temperature there will increase.
Important! When checking, you need to make sure that there are no cracks on the surface of the seal and that it did not disconnect from the door.
Sealing may also be disturbed due to skewing of the door or as a result of its deformation. Therefore, you need to make sure that everything is in order with the door.
The reason for the problem may also be failed thermostat. Therefore, when diagnosing your main kitchen device, it is necessary to check this element.
And the most likely reason for the poor operation of the refrigerator is a refrigerant leak. over, such a breakdown is also the most dangerous for health.
Important! The fact is that Freon. gas, which can harm the human body, acts as a refrigerator in the refrigerator. If a leak occurs, then its concentration in the kitchen, and in other rooms will increase. Therefore, in order not to risk health, you need to start repairs as soon as possible.
Overheating of the motor
Also, one of the most common reasons for the lack of high.quality frost is an overheating engine. In this case, the absence of cold in the chamber may also be accompanied. During overheating of the engine, thermal protection is turned on.
Having found the reason for the poor work of the refrigerator, you need to try to eliminate it. In some cases, this can be done independently. But with the most serious breakdowns, unfortunately, unfortunately, it will not work out without the help of the master.
If, with a thorough check of the refrigerator, it is found that it began to freely freeze due to the damaged door seal, then the latter will need to be replaced. You can replace it yourself, but the knowledgeable master will do much faster and better. This service, as a rule, is inexpensive. The main part of the money will have to be spent on the acquisition of the seal itself.
If the refrigerator door is deformed, as a result of which it stopped tightly fitting to the case, then its repair will be required. Its complexity depends on the degree of deformation. In some cases, you can do without the help of the master.
For example, when sagging the door, it will need to be adjusted with plastic washers. To do this, you have to first remove it. In this case, it will be easier to lay the washers and adjust the horizontal position. And if the door is poorly closed due to the fault of the landing hole, then you need to outweigh it to the other side.
The main purpose of the thermostat is to maintain a constant temperature in the chamber. In modern refrigerators, it is usually located above the door. If he caused the poor work of the refrigerator, then you need to correctly configure it or replace it.
To do it yourself, too, is not so easy. In this case, it will be necessary to dismantle the mode switch and eliminate the plastic structure that closes the relay.
The main signs of a malfunction of the thermostat are a long “resting” engine and a constantly glowing light bulb in the refrigerator compartment. For diagnosis, a multimeter and screwdriver are usually used.
If there is a suspicion that the cause of the poor operation of the refrigerator is a freon leak, then you should check the metal capacitor located at the rear of the device.
You just need to check its temperature. With a leak, the capacitor will be cold. If there is no leakage, it will be warm. Checking the temperature of the capacitor, you must be careful. Perhaps he will be very hot.
If it turns out that the refrigerator’s malfunction was a refrigerant leak, then refueling by Freon will solve the problem.
Overheating of the engine
To eliminate the malfunction with an overheated motor, you just need to turn off the device from the network and give it a little time to cool.
Then you can turn on the refrigerator again and check if it works normal this time. If everything is fine, then the problem can be considered solved.
And in order to reduce the likelihood of re.overheating of the engine, you need to provide the device with high.quality ventilation. After all, the walls located nearby can block the access of fresh air to the working motor.
To prevent problems with the work of the refrigerator, the following rules must be followed.
By turning off the device, you must first install the temperature controller on the mark “0”. And only then can you disconnect the plug from the network.
You can not turn on the refrigerator immediately after the cleaning carried out in it. You need to give him time to stand a little and dry. Only then can you be included in the outlet.
