Ice and snow is freezing up in the freezer
Experienced housewives remember the times when refrigerators were not equipped with a freezer and from time to time it was necessary to defrost the unit. This is a long, labor-intensive and not the most pleasant thing to do. So if you suddenly found that your refrigerator decided to go back to the old days and freezes “coat” in the freezer. you should not let the matter go on its own.
Having detected increased ice formation in the freezer, first of all check whether the freezer is closed tightly. Maybe you have “stuffed” it so badly that the door doesn’t fit properly, and warm air is getting into the chamber. Everything is fine? Then the next step is to check the settings. “Frost” in the freezer can form if:
- Your freezer is in super freezing mode. Some fridge models do not cut out automatically and you have to turn it off manually.
- The temperature is set too low. It could have been an accident. the thermostat was damaged or someone at home “helped”. Or you were afraid that it was too hot in the kitchen, so you took precautionary measures. Remember: the optimal temperature in the freezer is.19.17°C. Even if the room is hot, there is no need to choose a colder mode: an efficient fridge always keeps the set temperature regardless of the ambient temperature!
The modes are also all right, but there is snow and ice in the freezer? In this case, unfortunately, we have to speak about malfunction.
Causes of ice and snow freezing, not related to refrigerator malfunction
The cooling mode is chosen correctly, but the fridge and/or freezer compartment is still covered with ice? Unfortunately, we have to state the fact of malfunction.
Why in Samsung two-chamber No-frost fridge there is ice in the freezer
Sometimes people face a problem: bought Samsung fridge No Frost, in the freezing chamber forms ice. This can be a consequence of a technical failure or a violation of the rules of operation of the device. It is possible to restore the correct operation of the product after determining the cause of ice formation in the freezer. It is possible to do it yourself or invite a specialist. The choice depends on the results of the initial diagnostics of your Samsung refrigerator.
Why is ice forming in the freezer compartment?
A refrigerator that supports No Frost technology is one of the latest advances in home appliances. It is the fridge every housewife dreams of. No wonder. When defrosting the usual fridges you have to drag the whole piles of ice out of it, but No Frost fridges do not need to defrost at all as no ice forms inside the fridge. All the food stored there stays fresh. And there is no frosting either in the main compartment or in the freezer compartment.
But sometimes you can still see ice in your No Frost fridge. It is not always the first sign of breakage or failure. It is not uncommon for frost to form in the main compartment and freezer compartment as a result of improper adjustment of the operating mode. Many housewives mistakenly think that the stronger the “freezing” the fridge, the better. But this is far from being true. the wrong mode will harm not only the fridge, but also the food stored in it.
Why does the fridge freeze too much?
If in the fridge, that supports No Frost technology the imposing “snow-pack” grows, the human factor can be the cause. In other words, housewives are often the ones who shorten the life of their appliances. The main causes of ice formation in a No Frost refrigerator are:
The selected mode ” Super-freezing “. Many No Frost fridges support “SuperFrost” technology, which automatically re-starts 24 hours after the appliance is plugged in. This operation mode helps to preserve the freshness of a large amount of products. If the refrigerator is on “Super-freeze” mode, it is not surprising that ice forms in the main compartment and freezer compartment. In order to make the ice disappear, you simply need to turn off the “Super freeze” mode. 2. Incorrect installation of the fridge. The manufacturers of home appliances recommend to leave the free space between the fridge and the back wall at least 5 cm. Otherwise, there will be improper air exchange in the refrigerator. In other words, the heat will not be dissipated from the back wall of the fridge. Consequently, your refrigerator will not freeze and does not dissipate heat well. It can lead to the appearance of ice. 3. Improperly selected cooling mode. As mentioned above, many housewives mistakenly set the maximum freezing mode. As a result of this frost has formed in the lower part of the refrigerator. This is especially true if the room in which the refrigerator is installed maintains too high a temperature. Thus the heat exchange between condenser and ambient is more and more impaired. And when the “Super-freezing” mode is selected, the condenser is forced to work at full speed.
If all the settings of the refrigerator are correct, its installation is also carried out according to all the rules, but ice is still formed, it indicates a breakdown of the household appliance.
Why if your No Frost Fridge Freezer Breaks, it Can Be Frosted
In order to understand why the frost appears in your No Frost fridge you should clearly understand the principle of operation of this household appliance. On the rear wall of the freezing chamber of the refrigerator the evaporator is located. Adjacent to the condenser are special air ducts and an air blower. The fan helps to move the cold air from the air ducts to the fridge compartment.
Heater that regulates the refrigerator defrosting mode is located directly behind the evaporator. There is frosting on the evaporator as the temperature in the fridge compartment decreases. It has to be defrosted regularly as soon as the heater is switched on. The frost accumulates in the tray that was designed for this purpose. As a result of the correct and well-coordinated operation of the cooling system, the refrigerator keeps food fresh and no ice forms in it.
According to the experience of “Nadezhda” service center specialists, the lion’s share of No Frost fridge breakages is caused by defrost system failure. It is practically impossible to monitor the evaporator by yourself because it is hidden behind the special panel. That is why the first signs of defrosting failure are the reduction of temperature in the refrigerating chamber and formation of ice in the freezer.
It is possible to find out if the No Frost system of the refrigerator defrosts properly operates without involving specialists. As soon as ice has formed in the freezer compartment and it has become too “warm” in the refrigerator compartment, the following steps must be taken:
These measures most often restore the operation of the appliance. But if after 1-2 weeks frost has reappeared in the freezer, the repair or full replacement of the defrost system is most likely required. In this case, it is necessary to call for help as soon as possible to the specialists of the service center “Hope”. The long-lasting operation of No Frost refrigerator with a defrost system that is not working properly can cause more serious damage.
What else besides the defrost system can break in a No Frost refrigerator
Frost in your No Frost refrigerator can form not only as a result of defrost system malfunction. Sometimes masters can identify other breakdowns of household appliances. The most common of them are:
Clogged drain hole designed for water drainage. Drainage hole plays an important role in the operation of the freezer compartment. Drain hole is periodically clogged with dust and dirt, sometimes with food crumbs. As a result, the water does not circulate properly through the drain and accumulates at the bottom of the freezer compartment and then freezes.
In order to eliminate this fault, the blockage must be unblocked as quickly as possible. This can be done with a squirt of warm water. If this does not help, you need to defrost the fridge completely. If this fails, use improvised means (cables or ropes) to clear the blockage.
The temperature sensor is out of order. This device controls the cooling system. So if the sensor is broken, it must be completely replaced. Long-lasting fridge operation with defective temperature sensor leads to premature compressor shutdown. This causes the freezer to “overfreeze” and ice to form.
Fixed: Frost Buildup In The Freezer Causes
The tightness of the door with the main chamber of the refrigerator is disturbed. If the refrigerator door is not closed tightly, warm air enters the main chamber. Condensation and then ice form as a result. In this case it is necessary to replace the door seal with a new one as soon as possible. This will help to restore the tightness of the refrigerator compartment and freezer compartment and return the temperature inside the refrigerator to its previous level. Also if necessary, you should check the tightness of the main door to the refrigerator chamber and replace the hinges.
Refrigerant leakage. This defect is usually caused by the cooling circuit leakage. Consequently, it is impossible to reach the set temperature in the freezer compartment and the motor is forced to run continuously. As a result, the main working mechanism of the refrigerator practically does not shut down, overheats and also breaks down.
In order to eliminate this malfunction it is necessary to detect the leak as soon as possible and fix it. Then it is necessary to restore airless mode in the cooling system and refill the fridge with the refrigerant.
As soon as you notice ice in the freezer or the main compartment of the refrigerator, you should contact a qualified technician of the “Nadezhda” service center as soon as possible. We are ready to repair any No Frost refrigerator as soon as possible.
The most frequent reasons of ice formation
The principle of operation of units with a drip type of freezing provides for the appearance of a layer of ice on the back wall. In appliances with No Frost technology the evaporator is located outside, and the stream of cold air is distributed evenly with the help of a fan.
Cooling level of food storage compartment is controlled by air flow, which is shut off by a damper. There is a heating element behind the evaporator. As it cools, frost forms on the evaporator, which thaws when the heater is turned on.
Moisture escapes through a channel into the reservoir located on the compressor of the appliance. Cyclic process provides cooling without forming a layer of frost. The freezing of ice in the freezing chamber indicates violation of the rules of operation or damage to the construction.
Increased formation of ice in the freezer compartment indicates that the super freezing mode or low temperature setting has been activated. A small layer of frost is allowed to form while the appliance is in operation.
If there is ice appearing in the Samsung No Frost fridge in the freezer compartment, there are several reasons for this problem. Damaged or skewed rubber seal lets the heat out when the door is closed. Frost formation due to temperature difference.
There appears ice in the freezer if the drain hole is clogged. The problem occurs in Samsung two-compartment models. Ice formation is possible if the heating element is damaged.
Why does ice form in the freezer compartment of a No Frost fridge??
A fridge with a No Frost system is a welcome addition to any kitchen. After all, according to its manufacturers, in such equipment no ice is formed and there is no need for regular defrosting. But everything is not so simple and even in the equipment zero frost in the freezer ice is formed at the bottom. In this case, do not panic, models with this functionality, really do not form an icy coat, but provided the serviceability of the unit and the correct choice of mode of operation.
Probable breakdowns and what to do
Sometimes it happens that the parameters are set correctly, the operation conditions are not violated, but all the same the ice continues to freeze on the back wall of the fridge. This can be caused by a more serious problem with your appliances. Sometimes it is possible to eliminate the defects independently, but more often it is necessary to replace the worn out or broken parts. For this purpose it is better to invite a specialist.
Certain signs will tell you the specifics of a breakdown. If you understand what caused them, you can understand how you can fix them.
|Freon leakage||often than not, refrigerant leaks at joints. This can occur if the parts are corroded from old age or improper use. It causes the compartments to get warmer. Compressor runs continuously but cannot raise the temperature. Frost builds up unevenly, most often in the corners, a spot may form where the freon leaks. If refrigerator is defrosted, after turning on it stops working.||Find the place of leakage, seal it up. Charge the system with freon. If necessary replace damaged or corroded parts.|
|Wear of the seal on the refrigerator door||If the rubber seal is peeling, cracking, or losing its elasticity, it is not sealing the compartments. Causes the temperature to rise. Fridge motor is running with rare interruptions. Snow evenly freezes on the walls. Evaporator also freezes.||The sealant has to be replaced if it is worn out. Sometimes it is enough to clean it, glue it and grease it with silicone grease to make it resilient again.|
|Magnetic valve breakage||Normally, this valve alternately turns on cooling only the freezer compartment or both at the same time. If defective, both compartments are permanently cooled. Cold air goes up and the refrigerator compartment overfreezes. Freeze on drawers, shelves, foodstuffs freeze and ice forms on the walls. Freezer compartment gets warmer.||Only an expert can solve the problem. Do not turn off or defrost refrigerator until it arrives.|
|Capillary cooling system is clogged||Pipes through which freon circulates may be clogged. Most often by clots of oil. Uniform coolant circulation is impaired, so the compressor will run without interruption. There is a thick layer of ice on the rear wall. Compressor is very hot, also side walls outside are warm.||Clean capillary pipe, re-fill it with freon. The oil also needs to be checked and changed if necessary.|
|Sensor malfunction||This sensor is present in the models with electronic control system. It monitors the cooling degree. If it is defective, a signal is given to the control unit to lower the temperature. Motor starts to run without interruption. This causes ice to appear on the rear wall.||Defective sensor needs to be replaced.|
|Compressor malfunction||In case of mechanical damage, loosened fasteners or loss of tightness, the motor may run without shutting down. It makes an unusual noise. Temperature rises in the freezer and fridge compartment overfreezes, ice appears on the walls.||Professional repair is necessary or the compressor could burn out.|
|Insulation freezing due to excessive moisture||This occurs if the compartments are not properly sealed, the door is opened frequently, or the food is not stored properly. Compressor becomes warmer inside the refrigerator. Ice appears in one place.||Insulation needs to be replaced.|
|The thermostat is out of order||often the thermostat of the refrigerator breaks down after a voltage drop in the network. It must regulate the cooling temperature. Compressor barely shuts off when defective. In the cooling chamber, the temperature drops drastically. Food freezes and ice freezes on the rear wall of the refrigerator.||It is necessary to replace the thermostat|
|Refrigerator compressor overload||Improper operating conditions, overloaded compartments, or warm foods are placed inside the refrigerator, can cause the compressor to overheat. To maintain desired temperature, compressor fails to shut off. Heavy cooling causes the walls of the refrigerator to freeze.||We need to free the shelves, arrange the products so that they do not block the fan, not to overload the chambers.|
|Start relay breakdown||This part is responsible for activation and deactivation of compressor in time. If it is faulty, the engine does not start. Or it switches on and then shuts off right away. Because of it the ice is formed inside the refrigerating chamber.||It needs professional repair.|
The Reasons of Ice Frosting in the Fridge with the No Frost System
If in the refrigerator, which supports No Frost technology, the impressive “snow hat” grows, the human factor can be the culprit. In other words, housewives themselves most often shorten the life of their unit. The main causes of ice buildup in a No Frost refrigerator are:
- Selected “Super-freezing” mode. Many No Frost fridges support the SuperFrost technology that automatically activates after 24 hours of plugging in. This mode of operation helps to preserve the freshness of a large volume of products. If the fridge is in the “Super-freezing” mode, then it is not surprising that in the main compartment and in the freezing chamber the formation of ice. In order to make the ice disappear, one should simply turn off the “Super-freezing” mode.
- Improperly installed refrigerator. The manufacturers of home appliances recommend leaving no less than 5 cm space between the fridge and the rear wall. Otherwise, there will be improper air exchange in the refrigerator. In other words, the heat will not be dissipated from the rear wall of the refrigerator. Consequently, the refrigerator will freeze badly and dissipate heat badly. This and can lead to frosting.
- The wrong cooling mode. As mentioned above, many housewives mistakenly set the maximum freezing mode. As a result, ice will form in the lower part of the refrigerator. This is especially true when the room in which the refrigerator is installed maintains too high a temperature. Thus, the heat exchange between the condenser and the environment is made more and more difficult. And with the “Super-freezing” mode selected, the condenser is forced to work at full throttle.
- If all the settings of the refrigerator are correct, its installation is also carried out according to all the rules, but ice is still formed, it indicates a breakdown of the household appliance.
- Frost in a No Frost fridge can form not only as a result of a faulty defrost system. Sometimes masters can identify other breakdowns of household appliances. The most common ones are:
- Drainage hole intended for water drainage is clogged. The water drainage channel plays an important role in the operation of the freezer compartment. The drain hole is periodically clogged with dust and dirt, sometimes with crumbs from food. As a result, water does not circulate properly through the drain and collects at the bottom of the freezer, then it freezes. In order to eliminate this malfunction, it is necessary to remove the clog as soon as possible. This can be done using a syringe with warm water. If this does not help, you must defrost the fridge completely. If this does not help, you can use improvised means (cables or ropes) to clear the blockage.
- Temperature sensor malfunctions. This device regulates the operation of the cooling system. Therefore, if the sensor is broken, it must be completely replaced. Long-lasting fridge operation with a defective temperature sensor leads to premature compressor shutdown. This causes the freezer to “over-freeze” and ice to form.
- The tightness of the door to the main chamber of the fridge is disturbed. If refrigerator door does not close tightly, warm air enters the main chamber. Condensation and then ice is forming as a result. In this case it is necessary to replace the door seal with a new one as soon as possible. It helps to restore the air tightness of the fridge compartment and freezer compartment and return the temperature mode inside the fridge to the previous level. Also, if necessary, you should check the tightness of the main door to the refrigerator chamber and replace the hinges.
- The refrigerant leakage. Common this malfunction occurs as a result of a breach in the tightness of the cooling circuit. Consequently, it is impossible to reach the set temperature in the fridge compartment, the motor is forced to run continuously. As a result, the main working mechanism of the refrigerator practically does not switch off, overheats and also breaks down.
Samsung No Frost, how to remove the ice in the freezing chamber
Why does the ice accumulate at the bottom of the freezer in a Samsung No Frost refrigerator?
Let me start with the fact that nothing appears out of nowhere and nothing disappears. The ice at the bottom of the freezing chamber of the Samsung fridge No Frost appears because of the fact that the condensate that has melted simply has nowhere to go. In general the following happens, the drain line that goes from under the freezer evaporator to the container on the motor is clogged. Many people think that this channel is clogged, some muck, that is due to hit any garbage. Yes indeed in the freezer stored all sorts of herbs such as parsley, dill and the like, of course the leaves can get into the channel through which the condensate flows down, but from experience I can say that this is extremely rare. Believe me, the channel drain debris clogs condensate in 10% of 100 cases, in most cases the culprit for this behavior of the refrigerator is frosting the drain pipe. In the video below I have shown how to install the flexible additional defrosting fan. You should definitely watch this video, then we’ll deal with the cases and questions of consumers of this technique, relating to this ailment
Watch video why there is ice collecting on the bottom of the freezer in your No Frost fridge
Let’s go back to the video and look at some of the nuances involved in installing a flexible heater. This video was first posted on youtube and now it’s time to explain it on my website, this video was made by me personally, so I know very well what I’m talking about. To begin, let’s see how the additional defrost works and what it is for. From the video above, you must have known that the evaporator’s refrigerant’s suction pipe, runs very close to the water’s drain pipe, as a result the condensate drain pipe is slowly icing up. This is the main reason why ice appears in the freezer compartment. Next we will consider the question that most interests everyone, that is, we will talk about the parameters and where to connect the contacts of our additional heater
- The power of the heater → You can use from 30 to 80 watts. The most important thing here is that it does not melt the plastic, i.e. the drain pipe. Take the heater and connect it to electricity, if you can hold it in your hands when it’s on, it’s fine for defrosting
- The length of the flexible heating element → It depends entirely on the model of your refrigerator and the arrangement of the freezer compartment. If the chamber is at the top, its length will be noticeably longer, because the heating element must be stretched across the drain tube. In general, take some long single flexible wire and try to install it exactly the same way the additional defrost will stand. This way you get the exact length. You don’t need to buy it to the length, it is better to let it be half a meter longer, the extra can be stacked at the bottom of the freezer evaporator
- Where to connect → This fan must run in parallel with the main defrost. So you have to solder the ends of the additional defrost to the contacts of the main defrost
Well basically that’s all, as you see there is nothing complicated, you can buy the heater itself practically in any specialized store online, the main thing is to know which one to buy. When you buy the gasket, choose one that will fit into a hole with a diameter of no more than 1 centimeter. Next, I will answer some of the questions that come up in my workshop about this. I think thanks to my answers, you will be able to understand whether you need to perform this procedure
I have a Samsung refrigerator with the No Frost system, after I bought it, after about three years, started this shit. In general, water is constantly accumulated in the freezer compartment, or rather water appears at first and then freezes. We have to defrost the fridge every month, although we used to do it once every two years. In general, to keep the food from spoiling, we take out the bottom drawer and scoop the ice out of the bottom of the freezer. Called several foremen, they shrug their shoulders and each time change the defrost sensor and clean the water drain tube from the freezer evaporator. For a while this helps, but then we notice the appearance of ice again
If you have changed the sensor defrost, as well as cleaned the channel drain condensate and the result remains the same, you need to install an additional heater, how to do this you can see in the video above. Cleaning the channel and replacing the defrost sensor is unlikely to help you
Recently, my Samsung refrigerator began to malfunction, the problem is that the top of the refrigerator began to drip water. The freezer freezes fine, but at the bottom of the freezer, we recently saw ice. The thing is that we haven’t defrosted it for a long time, and closer to summer we decided that we needed to prepare the fridge for berry picking. Start pulling out the food and it is frozen to the bottom of the freezer. We defrosted the fridge for 3 days, then turned it on. After 3 weeks, again found ice at the bottom of the freezer, and in the refrigerator compartment, water started dripping from the top again. The master changed the sensor of defrost, as well as the clock mechanism, but it is still there. As before the water is dripping from the top of the fridge compartment and there is ice in the freezer
The classical case for the Samsung No Frost refrigerator with the top location of the freezing compartment. Try again to clean the water drain channel. It is quite possible that something is sitting there, it happens quite often in such refrigerators. If that doesn’t work, install a flexible fan, that is additional defrost. I don’t think it has anything to do with the defrost sensor or the timer, it’s probably just a frosty drain pipe or clogged debris
Once a month I cleaned the drain pipe in the freezer, now the situation has been aggravated by the fact that the coil of the main heater has failed, it does not call at all and frost is freezing on the evaporator. In the online stores such a fan is not sold separately, only as a complete unit with the radiator. I watched your video, I understood the principle of the system. I have this question, is it possible to use such flexible heater as the basic, that is to wrap it around the evaporator and stick it in the drainage pipe. It seems to me, what is the difference, what will heat this radiator
The difference is big. the main heating element is in the aluminum casing and is located on the evaporator and due to this heat exchange occurs, if you install a flexible heating element, this heat exchange will not occur and it is possible that in the future icing on the freezer. If you can not find the original, you can install a universal one. You can see it in the photo below
Photo of glass defrost heater for No Frost refrigerator
It is very important to make sure that it fits, and the rest, as you said, evaporator doesn’t care what heats it. Do not forget about the additional heater, it must also be installed. If your fridge was overfreezing in the drain channel, it will be repeated in the future, so it is better to be reinsured. When you buy a glass heating element, be sure to find out the dimensions and measure the length of the evaporator, because you will need to install it exactly under the evaporator
