Belarusian brand refrigerators Atlant are famous for their reliability, but even the highest quality equipment requires attention over time. One of the common problems faced by owners of models with the system No Frostis fan failure. If you notice that ice has stopped forming in the freezer, and the temperature in the main compartment has risen above normal, most likely the circulation of cold air is disrupted.
Understanding what where is the fan located is in your refrigerator is the first and most important step towards self-diagnosis. Unlike older models with a drip system, here forced airflow is a critical element. Without a running motor, cold air cannot flow from the evaporator into the food storage chambers.
In this article we will analyze in detail the design of various modifications Atlantso that you can accurately determine the location of the unit. We will not use complex technical terms without explanation, but will provide clear instructions that will help you navigate the structure of your equipment.
⚠️ Attention: Before starting any work to find or replace parts, be sure to disconnect the refrigerator from the electrical network. Working with electrical appliances under voltage is deadly.
The principle of operation of the No Frost system in Atlant
To understand why a fan is needed and where to look for it, you need to briefly consider working principle defrosting systems. In models Atlantequipped with technology No Frost, cooling occurs not due to the contact of products with cold walls, but due to constant air circulation. The evaporator, which creates the cold, is usually hidden behind the back panel in the freezer or in a special compartment between the chambers.
It is fan (or a gear motor, or a turbine) that makes this air move. It takes the cooled masses from the evaporator and directs them through special channels into the freezing and refrigerating chambers. After the air gives off the cold to the products, it returns back to the evaporator for re-cooling. This cycle is repeated continuously as long as the refrigerator is turned on.
If the fan stops, the chain is broken. The evaporator continues to freeze, but the cold remains “locked” in the technical compartment. As a result, the freezer may only have a normal temperature at the back wall, while the refrigerator compartment becomes warm. Localizing the fault begins with understanding this pattern of air flow.
Typical fan locations
The location of the fan directly depends on the specific series and model of your refrigerator Atlant. Brand designers use several basic layout schemes, and knowing these nuances will save you time when searching. Most often, the motor is hidden in the upper part of the freezer or behind the back wall.
In most two-chamber models, the fan is installed in freezer compartment. It can be located:
- 🌀 Behind the top plastic cover of the freezer (in models with a top freezer).
- 🌀 In a niche behind the rear panel, next to the evaporator.
- 🌀 In a separate insulated box between the refrigerator and freezer chambers (in some two-compressor models).
- 🌀 In the lower part of the freezer, if we are talking about models with a lower freezer compartment (combines).
It is important to note that in some modifications not one, but two fans are used: one for the freezer, the second - for the refrigerator compartment. However, in classic Atlantakh more often there is a scheme with one powerful motor, which distributes air through a system of dampers and channels in both compartments.
| Refrigerator series | Fan location | Access |
|---|---|---|
| Atlant 450 series | Behind the rear panel of the freezer | Middle (you need to remove the shelves) |
| Atlant 600 series | At the top freezer | Simple (remove the lid) |
| Atlant 700 series | Behind the evaporator (in the niche) | Complicated (disassembling the case) |
| Atlant XM-4008 | Near the defrost heating element | Medium |
If you do not find the fan in the indicated locations, you should refer to the technical documentation of your specific model. Sometimes manufacturers make changes to the design, changing the location of the units without changing the series index.
Access to the fan in the freezer
The most common scenario for refrigerators Atlant is the location of the blower motor directly in the freezer. To get to it, you will need a minimum set of tools: a Phillips screwdriver, a flat-head screwdriver for prying up the plastic latches and, possibly, a knife to remove the ice crust.
The search and access process usually looks like this. First you need to completely release the freezer compartment from the products and remove all drawers and shelves. Then inspect the back wall. In most cases, it is a plastic panel secured with screws or plastic latches. After unscrewing the fasteners, carefully pull the panel towards you.
Behind this panel you will see an aluminum evaporator radiator and next to it - fan. It can be mounted on a bracket or inserted into rubber shock absorbers. In models with the No Frost system, the fan is often enclosed in a plastic casing that directs the air flow. If you see ice on the blades or in the motor itself, this is a sure sign of a malfunction of the defrost system, and not just the fan itself.
⚠️ Attention: Plastic becomes very brittle at low temperatures. Do not use excessive force when removing the panels to avoid breaking the mounting lugs. Allow the chamber to warm up a little if it is covered with ice.
In some cases, the fan may be hidden deeper, behind a layer of polyurethane foam or an additional heat-insulating screen. In such situations, it is recommended to act with extreme caution so as not to damage the freon pipelines.
Location features in two-compressor models
Two-compressor refrigerators Atlant have a more complex design, since each cooling circuit (for the refrigerator and freezer compartments) operates independently. This means that the fans, if provided for by the design, can also be separated or have a unique connection diagram.
In such units, the freezer fan is often located similarly to single-compressor models - at the top or behind the freezer. However, the refrigerator fan (if the model supports the mode No Frost
- ❄️ In the upper part of the refrigerator compartment, hidden by a decorative strip.
- ❄️ In a special channel between the chambers, access to which is only possible from the freezer side or by removing the back wall of the refrigerator.
- ❄️ Next to the lighting lamp (in rare older models with forced circulation).
If your refrigerator is marked Full No Frost, both compartments are served by a forced circulation system. In this case, the search for a fan in the refrigerator compartment becomes relevant. Most often, it is hidden behind the top. cover inside the chamber, where temperature sensors and an air flow control flap are also located.
Why is the fan humming?
Extraneous noise during fan operation is most often caused by ice freezing on the blades, which touches the housing, or wear of the sliding bearings of the motor itself.
Diagnostics fan malfunctions
Before proceeding with disassembly and replacement, you need to make sure that the problem lies in the fan. Sometimes the lack of cold is caused by a freon leak or a compressor malfunction, and the fan simply does not turn on due to a signal from the control board.
Perform initial diagnostics. Open the freezer door and press the light switch button (or door control button, if equipped). On some models, the fan should stop when the door is open. If it is silent even with the door closed, listen.
Main signs of a malfunction:
- 🔇 Complete absence of sound from the fan when the compressor is running.
- 🔊 Strong hum, crackling or grinding coming from the back of the chamber.
- 🌡️ The temperature in the chambers does not drop, although the compressor works continuously.
- ❄️ The presence of a “fur coat” or ice on the back wall of the freezer when the motor is running.
For an accurate check, you can apply voltage to the fan contacts directly (observing the polarity and voltage indicated on motor housing). If, when power is applied, the blades do not rotate or rotate with difficulty, the element requires replacement. It is also worth checking the integrity of the wiring going to the motor, since in conditions of vibration and cold the wires can break.
☑️ Fan diagnostics
Replacement and maintenance of the blower system
If Diagnostics confirmed that the fan is faulty and needs to be replaced. Refrigerators Atlant usually use standard motors, which can be found in spare parts stores by catalog number. Before purchasing a new part, be sure to remove the old one and compare the dimensions, type of fastening and connection connector.
The replacement process looks like this:
- Disconnect the refrigerator from the network.
- Remove the panel covering the fan.
- Disconnect the electrical connector.
- Remove the mounting screws or release the latches holding the motor.
- Install a new fan, connect the connector and reassemble the structure in the reverse order.
The important step is prevention. Often the fan stops working not because it has burned out, but because it is jammed with ice. This occurs due to a malfunction of the defrost system (the heating element, timer or defrost sensor has burned out). If you simply replace the fan, but do not eliminate the cause of the icing, the situation will repeat itself in a week. Therefore, when replacing the motor, always check the cleanliness of the drainage hole and the condition of the defrost heater.
⚠️ Attention: Do not use sharp metal objects (knives, screwdrivers) to chip ice around the fan. You can damage the aluminum evaporator tubes, which will lead to freon leakage and costly repairs.
After assembly, turn on the refrigerator and check its operation for several hours. Make sure that the cold air is evenly distributed throughout the chambers and that there is no extraneous noise.
Is it possible to temporarily operate a refrigerator without a fan?
Technically, the refrigerator will work, but the cooling efficiency will fall by 60-70%. Food in the freezer may begin to thaw, and the temperature in the refrigerator compartment will rise to critical levels. Long-term operation in this mode will lead to overload of the compressor.
What kind of lubricant should you lubricate the fan if it starts to make noise?
Usually such motors have sliding bushings. You can try dripping silicone oil or special grease for refrigerators into the shaft area. However, this is a temporary measure: if the bearing is worn out, only replacement will help.
Why does the fan turn on with a delay?
In some models Atlant a delay in turning on the fan after starting the compressor is programmed in the electronic control module. This is necessary so that the evaporator has time to cool before active airflow begins, which prevents warm, moist air from entering the cold radiator.
Where can I find the replacement part number?
The part number is usually stamped on the body of the fan itself or pasted on a label. You can also find the catalog number in the service documentation for your refrigerator model or use a search using the VIN code of the equipment in specialized stores.
Do you need to defrost the refrigerator before replacing?
Yes, complete defrosting (at least 10-12 hours) is required. This will remove ice plugs that could block the fan, and will protect you from accidental damage to fragile plastic elements during dismantling.
