Samsung Nou Frost two-chamber refrigerator malfunction

The South Korean brand Samsung is famous for producing high-quality and durable refrigeration units. This manufacturer was one of the first to introduce No Frost technology in its models, making them even more attractive to the consumer. But this technique also has a certain resource - usually after seven years of uninterrupted operation there are various breakdowns. Most often this is due to the refusal of periodic maintenance of equipment. The list of the most common faults in Samsung's two-chamber refrigerators "No Frost" is mainly related to various problems in the cooling system.

Features of such equipment

You can select the following faults in the temperature of the two-chamber refrigerator Samsung "No Frost":

• formation of an ice crust (the temperature is set incorrectly), which increases electricity consumption;
• full tray of water (due to the leak, the products will spoil quickly).

A distinctive feature of Samsung refrigerators is the constant temperature of each of the chambers (the difference will be within 0,3 degrees). Different parts of the device have different modes - they differ significantly and decrease from top to bottom..

1. In the main chamber, the temperature corresponds to three degrees of heat, change within plus or minus two degrees is allowed.
2. Now let's move on to the freezer - the temperature is already "prevailing" within 18 degrees of frost. To adjust (and adjustments are allowed), you need to study the instructions, attached to the model.

Auxiliary sensors

The user can independently regulate the temperature from the control panel - information on it is provided by sensors located inside the device. It is they who monitor the territory allotted to them in the unit. The sensors have the following parts of the device:

• common refrigerator;
• internal space in the evaporator;
• freezer compartment;
• control panel (to measure the environment).

The required temperature is set using the Cooling Power or Fridge keys (or mechanical handle, revolving). On the most control and visible to the user panel the data from sensors arrive through the control circuit. In most cases, models from this brand have 502AT controllers, which are universal.

Failure of any of the sensors of the device leads to malfunction of the entire Samsung refrigerator. It is best to entrust such repairs to the appropriate specialists.

Possible problems

The control panel will definitely show, the device has failed: the corresponding indicator will flash. This failure can be caused by one of the following.

1. The temperature rise is higher, than on 3 degrees. This often happens due to constantly opening the door in hot weather. The problem is solved simply: the refrigerator should be tightly closed and not opened approximately 2-3 years.
2. The temperature mode was not set - this shortcoming can be eliminated, following the instructions.
3. There is a separate indicator in the ice tray. He can signal, that the part is installed incorrectly - this point should be checked and misunderstandings resolved.
4. Sometimes when moving the door there is a fault in the contacts of the electronic panel. In this case, it's best to double-check the connection.

How to solve the problem of setting the temperature in the units from this manufacturer? The instructions for each model contain detailed information about it, how to do it right.

Hidden malfunctions of Samsung's two-chamber refrigerators

A faulty Samsung refrigerator may work, outwardly giving nothing "bad". However, over time, the problem will only get worse. That is why the user should pay attention to any signals, which are signs of more serious future problems. Consider the most common of them. In the first place - a defective relay in the evaporator.

The main feature is the ever-increasing frost in this part of the unit. As a result of such breakage the evaporator will be covered with a layer of snow literally for 2-3 days. The end result - the unit simply stops freezing due to the high temperature in the chambers. This is not surprising, after all, the compressor is no longer turned off by the thermostat.

What can be done in this case? The unit must be shown to specialists. But before that you will need to do the following.

1. The refrigerator is disconnected from the mains.
2. The device is released from the contents (products). You will also need to remove all drawers and shelves.
3. Next, open the door wide in the refrigerator and defrost all appliances 8-10 hours.

Recommendation from the service center, probably, will be revealed, control board replacement.

in addition, the refrigerator timer often breaks. Interesting, that here all the symptoms are similar to the case described above. Therefore, again, it is recommended to call a specialist, before repeating similar occasions with thermal relays.

Other possible breakdowns of the unit

Faults in refrigerators with two chambers can be different. Units are considered particularly vulnerable, having electric control (almost all of the modern models). The list of problems is typical:

• the appearance of increased knocking, noise or rattle;
• poor performance of the refrigerator (at excellent indicators of freezing);
• the opposite of the above result;
• accumulation of water in the refrigerator;
• delaying the start of the motor from the compressor;
• operation of the compressor without exception;
• electrical panel faults.

All these failures often come from complex electronic components and system parts (evaporator, thermostat, board details), so, their diagnosis and troubleshooting should be done so much at the appropriate professional level. There are also "diseases", which are most prone to two-chamber models of "Samsung". Mechanical damage to the device leads to this result:

• break in the electrical circuit Tena thawing;
• fluid leakage from the freon circuit.

Sometimes the user is to blame, which as a result of improper operation has created problems with clogging of the capillary pipeline or the filter of the dehumidifier.

Of the others, already rare breakdowns can be noted:

• break of a compressor winding (the engine jams and stops spinning);
• evaporator cooling fan defects (the unit stops making noise, and the temperature in the chambers rises).

The user is not recommended to try to deal with these failures, Moreover, if he does not know most of these terms. Such initiative may deprive the user of warranty service from the manufacturer.

However, there is that, what you can eliminate with your own hands is to adjust the doors and hinges from them, predominance of doors, power cord replacement, cleaning the drain from debris, replacement of automation components. It is allowed to make independent repairs here (if the user is confident). When it comes to replacing failed parts, then only a qualified specialist from an authorized service center will be able to offer original options..

Preventive measures to prevent breakdowns

Following simple guidelines will allow refrigerators with the "No Frost" system to last long and without failure..

1. Such units should not be defrosted by hand: here it is allowed to do auto defrost once a year to wash and clean the device and its parts.
2. The drip-type compartment is defrosted in only one chamber.
3. If it is necessary to clean the unit in the included condition, it is best to do this in hot weather, otherwise the overheated refrigerator will break.
4. Wash the device 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 should be removed immediately.
5. The back surface should also be cleaned of dust and dirt - they can get into other parts and components of the device..
6. Products are stored in boxes and packages.
7. Do not use the device outdoors and allow water to get under the water (example, rain).
8. The refrigerator should be kept away from direct sunlight and heat sources.

Samsung two-chamber refrigerators with the "No Frost" system are one of the most popular models among consumers. Reliable, economic and silent models have gained popularity due to their ability to set the desired temperature. Good care and timely maintenance of Samsung's two-chamber refrigerators will increase the service life of the devices and prevent malfunctions and breakdowns.
