Overview of malfunctions of the two-chamber refrigerator Samsung No Frost

The South Korean brand Samsung has become famous for the release of high-quality and durable refrigeration units. This manufacturer was one of the first to introduce No Frost technology into its models, making them even more attractive to consumers. But this technique also has a certain resource - usually after seven years of uninterrupted operation, various failures occur. Most often this happens due to the failure of periodic maintenance of equipment. The list of the most common malfunctions in two-chamber refrigerators Samsung Nou Frost is mainly associated with various problems in the cooling system.

Features of this technology

The following malfunctions can be identified in the temperature mode of the two-chamber refrigerator Samsung Nou Frost:

• the formation of ice crust (incorrectly set temperature), which increases the consumption of electricity;
• full pan of water (products will deteriorate quickly due to leakage).

A distinctive feature of Samsung refrigerators is to constant temperature each camera (the difference will be within 0.3 degrees). Different modes are set in different parts of the device - they differ significantly and decrease from top to bottom.

1. In the main chamber, the temperature indicator corresponds to three degrees of heat, a change within plus or minus two degrees is allowed.
2. Now let's move on to the freezer - here the temperature is already “reigning” within 18 degrees of frost. To adjust (and adjustment is allowed), it is necessary to study the instruction attached to the model.

Helpers Sensors

The user can independently regulate the temperature from the control panel - information on it is provided by sensors located inside the device. They follow the territory allocated to them in the aggregate. Sensors have the following device parts:

• common refrigerator;
• internal space in the evaporator;
• freezer chamber;
• control panel (for measuring the environment).

Installation required temperature by using the Cooling Power or Fridge keys (or a mechanical rotary knob). On the control panel itself and visible to the user, the data from the sensors is received through the control circuit. In most cases, the models from this brand are 502AT controllers, which are universal.

Failure of any of the sensors of the device leads to malfunction of the entire Samsung refrigerator. This repair is best to entrust the relevant specialists.

Possible problems

The control panel will surely show that the device has failed: the corresponding indicator will flash. However, one of the following causes may cause a problem.

1. The temperature rises by more than 3 degrees. Often this happens because constantly open door in hot weather. The problem is solved simply: the refrigerator should be tightly closed and not opened for about 2-3 hours.
2. The temperature mode was not set - this defect can be eliminated, guided by the instructions.
3. There is a separate indicator in the ice tray. It can signal that the part is installed incorrectly - this point should be checked and a misunderstanding corrected.
4. Sometimes when rearranging doors, there is a malfunction in electronic panel contacts. In this case it is better to check the connections once again.

How to solve the problem with setting the temperature in units from this manufacturer? In the instructions of each model is detailed information on how to do it.

Hidden faults two-chamber refrigerators Samsung

A defective Samsung refrigerator can work without seemingly giving out something amiss. However, over time, the problem will only worsen. That is why the user should pay attention to any signals that are signs of more serious future problems. Consider the most common among them. At the first place - defective relay in the evaporator.

The main feature is a constantly increasing frost in this part of the unit. As a result of such a breakdown, the evaporator will be covered with a layer of snow in literally 2-3 days. The final result - the unit simply stops freezing due to the increased temperature in the chambers.This is not surprising, because the compressor is no longer disconnected by the thermostat.

Frost on the back of the fridge

What can you do yourself in this case? The unit must be shown to experts. But before that it will be necessary to do the following.

1. The refrigerator is disconnected from the network.
2. The device is released from its contents (products). You will also need to pull out all the drawers and shelves.
3. Then it should be wide open in the refrigerator door and defrost all devices in 8-10 hours.

The recommendation from the service center is likely to be the replacement of the control board.

In addition, often breaks refrigerator timer. It is interesting that here all the symptoms are similar to the above case. Therefore, again, it is recommended to call a specialist before repeating actions similar to the case with a thermal relay.

Other possible unit breakdowns

Malfunctions in refrigerators with two chambers may be different. Aggregates are considered to be especially vulnerable. having electric control (almost all of the modern models). The list of problems is typical:

• the appearance of increased knocking, noise interference or rattling;
• poor operation of the refrigerator compartment (with excellent freezing performance);
• opposite to the above result;
• accumulation in the refrigerator water;
• tightening the start of the motor from the compressor;
• compressor operation without shutdown;
• malfunctions

All these failures most often come from complex electronic components and parts of the system (evaporator, thermostat, board parts), which means that their diagnosis and troubleshooting should be done so much at an appropriate professional level. There are also “diseases” to which Samsung’s two-chamber models are most often affected. Mechanical damage devices lead to this result:

• break in the electric circuit of the heater for defrosting;
• fluid leak from the freon circuit.

Sometimes it is the user who is to blame who, as a result of improper operation, created problems with clogging of the capillary line or filter of the dryer.

Of the others, already rarely occurring breakdowns you can note:

• breakage of the compressor winding (the engine is jammed and stops rotating);
• fan defects in the evaporator blowing (the unit stops making noise, and the temperature in the chambers rises).

The user is not recommended to try to understand the specified breakdowns on his own, especially if he does not know most of the specified terms.Such initiative can deprive the user of warranty service from the manufacturer.

However, there is something that can be eliminated with your own hands - it is the adjustment of the doors and hinges from them, reweighing the doors, replacing the power cord, cleaning the drain from blockages, replacing automation components. It is allowed to make an independent repair (if the user is confident in their abilities). If we are talking about replacing broken parts, then only original specialists from an authorized service center will be able to offer original options.

Preventive measures to prevent breakage

Compliance with simple recommendations will allow refrigerators with the “Nou Frost” system to serve for a long time and without fail.

1. You should not defrost such units manually: here it is allowed to do automatic defrosting once a year to wash and clean the device and its parts.
2. Department drip type defrosted in only one chamber.
3. If it was necessary to clean the unit when it is on, it is best to do it in case of not hot weather, otherwise the overheated refrigerator will break.
4. Wash the device should without the use of abrasive chemicals - Enough soda solution and water. After the procedure, the surface is wiped with a clean, damp cloth. All stains that appear should be removed immediately.
5. The back surface should also be cleaned from dust and dirt - they can enter into other parts and components of the device.
6. Products are stored in packages and packages.
7. Can not use the machine outdoor and allow it to fall under the stream of water (for example, rain).
8. The refrigerator must be kept away from direct sunlight and heat sources.

Samsung's two-compartment refrigerators with the Nou Frost system are among the most sought-after models among consumers. Reliable, economical and silent models have gained popularity due to their ability to independently set the required temperature. Good care and timely maintenance of Samsung's two-compartment refrigerators will increase the service life of the devices and prevent malfunctions and breakdowns.
