In the article you will learn about typical malfunctions of the Nou Frost refrigerator. How to deal with the fact that it does not turn off, does not cool or accumulates ice? To find out the cause of the problem, you need to understand the principle of Nou Frost.
How the No Frost System Works
The evaporator in the technique is located behind the rear or side wall. Two-compartment refrigerators can be equipped with two fans, one in each section. These fans drive cold air through the chambers.
After the motor-compressor stops, defrost starts. Moisture drains into the drain hole and is discharged from the system. The following advantages of Nou Frost can be noted:
- uniform cooling of products in the compartment;
- slight temperature difference between the shelves;
- minimum level of care - the system rarely needs defrosting;
- lack of snow in the freezer;
- superfast freezing.
There are also disadvantages:
- due to the operation of the fans, the noise level increases;
- lower loading due to design;
- consumption of more electricity;
- high cost (compared to drip type refrigerators).
What doesn't work in the No Frost refrigerator
What to do if the No Frost refrigerator is constantly working and does not turn off? Understand the reasons for this behavior.
The refrigerator does not turn off
The motor must be switched off periodically. Continuous operation of the compressor leads to wear of its components. Therefore, the first thing to check:
- The door of the camera. Is it tightly closed? Maybe something is bothering her or the seal needs to be replaced. Problems with closing the door are solved immediately, otherwise warm air will constantly enter the compartment. Because of which the motor does not turn off.
- Installed Modes. If you set the super-freezing mode on the electromechanical control, it will not turn off until you turn the knob.
- The presence of ventilation. If the room is stuffy, or the refrigerator stands close to the wall, the battery, the compressor will constantly pump cold.
You checked everything and even replaced the seal, but the motor continues to work? Perhaps a breakdown occurred:
- 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 the wrong signals, so the cooling in the cameras does not turn off.
- The control module burned out. The reason is a faulty board or its elements - you cannot trust it with the operation of the equipment, you need to carry out diagnostics and replacement.
- Problems with the evaporator. Probably, a capillary tube clogged. It is necessary to call a master who will inspect and eliminate the blockage.
- The system has a freon gas leak. He is responsible for cooling, so the refrigerator tries to compensate for the loss of refrigerant by constant operation.
- Problems with a compressor that cannot create normal pressure for cooling.
If you notice a similar problem, contact a service center. No need to wait until the equipment finally fails. Similar malfunctions occur with Nou Frost Stinol, Atlant, Virpul, Daewoo refrigerators and others.
Fan does not work in Nou Frost refrigerator
A fan is an essential element in the system. Without it, cold air will not be able to enter the compartment and cool the food. There are two problems with the fan: either it does not work, or it constantly works. Let's consider both signs in more detail.
The fan has stopped working
Most often this happens when the blades of the part freeze. Open the chamber door and look - if the blades are overgrown with a layer of ice and snow, you need to urgently defrost the refrigerator. It is possible that the refrigerant escaped or the drainage hole clogged where the thawed water flows.
Defrosting must be performed for at least 10 hours, preferably a day.
If even after defrosting the fan does not start working, check its motor for serviceability. When burning, the part must be completely changed.
The fan is constantly running.
When the blades rotate without stopping, the cause may be in the evaporator, which is overgrown with ice. Air begins to circulate poorly, so the fan works to lower the temperature in the chamber.
Similar signs may indicate a malfunction of the compressor, control module, temperature sensor. If the latter malfunctions, the board receives incorrect information about the temperature in the chamber, therefore it makes the motor work without stopping. In such cases, a complete diagnosis of the refrigerator is needed.
Faults Nou Frost Samsung Refrigerator
Appliances from the manufacturer Samsung are always equipped with the latest developments, modern electronic control. Refrigeration equipment (CW) with the No Frost system is no exception. What kind of breakdowns can be found in the Samsung dual-compartment refrigerator? Let's consider in more detail.
Since the temperature in each compartment is almost the same (a slight difference of 0.3 degrees), the user should pay attention to:
- the appearance of an ice crust on the walls;
- flow under the refrigerator, water in the pan;
- temperature increase in the chamber - maybe you too often opened the compartment door, or it is not tightly closed.
If a display is installed on the panel, it displays breakdowns with icons or error codes. So you can find out that there are problems with the door contacts. When rearranging or moving the door, the connections could be broken. You may have set the wrong temperature. It’s easy to fix the problem by adjusting the readings.
When the refrigerator is broken, you can notice the corresponding signs:
- Snow layer in the evaporator area - relay malfunction. The evaporator will soon grow snow, the refrigerator will fail. It is better to call the wizard to replace the part. To speed up repairs, defrost the compartment for 10 hours.
- If the timer breaks down, the signs are exactly the same as in the previous case.
Typical malfunctions of Samsung Nou Frost refrigerators:
- noisy work XO, extraneous sounds;
- one of the cameras does not work well;
- non-stop compressor operation;
- inoperative display;
- refrigerant leak due to mechanical damage.
Electronic control allows the user to practically not interfere with the settings of the refrigerator. However, electronics is its weak point. Be careful when operating.
Faults Nou Frost Indesit
Indesit refrigerators are also equipped with modern technologies, while the cost of the equipment compares favorably with other models. What to do in case of a malfunction of a two-chamber refrigerator and what breakdowns are most often found, read below.
Most often, a freezer compartment does not work in Indesit. In this case, a snow coat is formed on the walls. What happened:
- Did you notice that the engine is constantly running, but the temperature is increased in the compartment? There may be several reasons.
A broken thermostat no longer communicates with the module, so the module does not turn off cooling. Check and replace the thermostat.
A damaged wall or clogged capillary will cause freon to leak. It is necessary to check and eliminate the cause of the leak.
Sealing the door seal also contributes to non-stop operation. - The refrigerator only works for a few seconds or does not turn on at all. Several options are possible: the start relay, the electronic module or its wiring is broken.
- Failure of the temperature sensor or clogging of its tube is also accompanied by a buildup of snow.
You may encounter such problems:
- Problems with the fan. In addition to external signs, an error code may appear on the display. By the code you will understand exactly where to look for damage. Most often, there are problems with the wiring between the board and the fan. The contacts are dialed with a multimeter, after which the faulty elements change.
- Faulty heater defrost. In this case, the code F07 can be displayed on the display, which means the need to check the connections and the heater itself.
There are also problems with the motor-compressor. In this case, a replacement is recommended.
Faults Nou Frost LG
If the LV double-chamber refrigerator does not work, an urgent need to be rectified, otherwise food spoilage cannot be avoided. Immediately check the connection of the equipment to the network: maybe the plug is loose or the integrity of the wire is broken. Also inspect the XO case: maybe it is located with an inclination forward and the door is slightly ajar. Then you need to install the equipment according to the level.
How to identify other breakdowns:
- Compressor wear. At the same time, clicks are heard, although the engine does not start. This starting relay tries to turn on the motor, but to no avail. A complete compressor replacement is needed.
- Malfunction of the air sensor or thermostat, depending on the type of control. The engine is silent, but the light in the compartment is working. This means that the module does not receive a signal about the temperature in the chamber; therefore, it does not include cooling.
- If the LG No Frost refrigerator does not work at all, does not show “signs of life,” then diagnostics of the electronic module is needed.
Over time, users complain that the equipment is working loudly. The most harmless reasons that are easy to fix are improper installation, crowded with branch products. What should be done:
- set the pots in the compartment away from each other;
- move the refrigerator away from the wall and furniture.
Follow the instructions for installation.
Faults Nou Frost "Bosch"
Bosch refrigeration equipment stands out for its reliability and quality. In the event of a breakdown of the two-chamber refrigerator, you need to contact the master or try to figure out the problem yourself.
Common breakdowns:
- The refrigerator does not work or does not turn off. The reasons for this behavior are described above.
- Condensation is collected in the compartment. This happens when the door is not properly closed: warm air enters the chilled chamber, forming condensate, which turns into ice.
- Failure in the Nou Frost system. Products do not cool properly.
- One of the cameras does not work or weakly freezes.
Watch the video on the topic:
It will require repair of equipment, replacement of damaged parts. Often, such malfunctions occur in a double-chamber refrigerator “Electrolux” with “Know Frost”. Sometimes the system does not work in Siemens refrigerators. Therefore, all the breakdowns described in the article can occur in the technique of any brand.
