Refrigerators Atlant with the system NoFrost are equipped with a fan that ensures uniform distribution of cold air throughout the chambers. However, when this unit breaks down, many users are faced with a problem: where exactly to look for the fan, how to check it, and can it be replaced independently? In this article we will analyze exact locations fans in models Atlant of different series, provide diagrams and photos, and also explain how to diagnose a malfunction without calling a technician.
It is important to understand that in refrigerators Atlant the fan can be located in different places depending on the type of cooling system. For example, in models with Full NoFrost (two-chamber) there are usually two fans installed - for the refrigerator and freezer compartments, and in Frost Free (combined) - only one. We will look at each case in detail so that you can quickly navigate.
If your refrigerator freezes worse, an uncharacteristic noise appears, or ice forms on the back wall - these are direct signs of problems with the fan. But before disassembling the equipment, let's figure out exactly where to look for it and how to diagnose it correctly.
Types of cooling systems in Atlant refrigerators and the location of fans
Refrigerators Atlant are produced with three main types of cooling systems, on which the number and location of fans depends:
- 🔹 Full NoFrost — two fans: one in the freezer (behind the rear panel), the second in the refrigerator (above the evaporator).
- 🔹 Frost Free — one fan in the freezer, the refrigerator is cooled by natural circulation.
- 🔹 Drip system — no fan (exception: some new ones models with a hybrid system).
To determine exactly which system is installed in your refrigerator, look at nameplate (metal plate) on the back or in the technical data sheet. Models with NoFrost usually have marking NF, FNF or TNF in the name. For example, Atlant XM 6025-031 NF is Full NoFrost.
If you are not sure about the type of system, pay attention to the presence of ventilation holes between the chambers. In models with Full NoFrost they are, and in Frost Free - only in the freezer.
Where is the fan in the Atlant refrigerator with Full NoFrost
In two-chamber models Atlant s Full NoFrost (for example, XM 6021-031, XM 6026-031) are installed two fans: one in the freezer, the second in refrigeration. Their location is standardized, so you can find them according to the following scheme:
- Freezer fan —located behind the rear plastic panel, next to the evaporator. To get to it, you need to remove the back wall of the freezer (it is secured with latches or screws).
- Refrigerator compartment fan —located in the upper part of the back wall, under the air duct. Often closed with a plastic cover with clips.
The photo below shows a typical view of the freezer (left) and refrigerator (right) fan in models Atlant:
Photo of fans in the Atlant refrigerator Full NoFrost
In the freezer, the fan is a plastic impeller on a motor mounted on a metal bracket. In the refrigerator compartment it is smaller in size and is often white or gray in color. Both fans are connected to the control board through connectors with 2-3 wires.
If you hear a hum, but the air is not circulating, the problem may be that the blades are frozen. In this case, do not rush to disassemble the refrigerator - try it first defrost it for 12-24 hours. If after defrosting the fan does not work, diagnostics will be required.
How to find the fan in the Atlant refrigerator with Frost Free
In models with the system Frost Free (for example, Atlant XM 4021-022, XM 4621-100) the fan is installed only in the freezer compartment. It is responsible for air circulation through the evaporator and further distribution of cold throughout both chambers through air ducts.
To get to the fan:
- Unplug the refrigerator.
- Remove all food from the freezer.
- Remove the back plastic panel (it is secured with 4-6 screws or latches).
- The fan will be located to the right or left of the evaporator (radiator with tubes).
Externally, it looks like a small electric motor with a plastic impeller with a diameter of 8–12 cm. Two wires (phase and zero) are suitable for it, sometimes a third (for the Hall sensor). If the fan does not rotate, but voltage is supplied to it, most likely the motor or bearing has failed.
| Refrigerator model | System type | Number of fans | Location |
|---|---|---|---|
| Atlant XM 6021-031 | Full NoFrost | 2 | Freezer (behind the panel), refrigerator compartment (top) |
| Atlant XM 4021-022 | Frost Free | 1 | Freezer (behind the evaporator) |
| Atlant XM 4421-089 | Frost Free | 1 | Freezer (to the right of the evaporator) |
| Atlant XM 6026-031 | Full NoFrost | 2 | Freezer (bottom fan), refrigerator compartment (under the air duct) |
If your model is not indicated in the table, focus on the type of system (Full NoFrost or Frost Free). In 90% of cases, the location of the fans is the same.
Symptoms of fan malfunction and diagnostic methods
A faulty fan manifests itself with several characteristic symptoms. If you notice at least one of them, it’s worth checking the operation of the unit:
- ❄️ Uneven cooling —it’s cold in the freezer, but it’s warm in the refrigerator compartment (or vice versa).
- 🔊 Extraordinary sounds —humming, grinding or crackling noise due to a bearing or ice on blades.
- 💨 Lack of air circulation —if you put your hand near the ventilation holes, there is no air flow.
- ⚡ The refrigerator turns on frequently —the compressor works non-stop, trying to compensate for the lack of cooling.
To diagnose, follow these steps:
Unplug the refrigerator and defrost it|Remove the back panel of the freezer/refrigerator|Check if the fan blades rotate freely (manually)|Connect the refrigerator and listen to see if the motor starts|Ring motor winding with a multimeter (resistance should be 200–500 Ohms) -->
If the fan does not rotate when power is applied, but the blades rotate freely by hand, the problem is electric motor. If the blades are jammed, bearing failure or freezing may occur. In both cases, replacement will be required.
⚠️ Attention: If you hear a crunch when manually rotating the blades or they rotate with difficulty, do not turn on the refrigerator - this may lead to burnout of the motor winding.
How to replace a fan in an Atlant refrigerator with your own hands
Replacing a fan is a task of medium complexity that requires accuracy and basic skills in working with tools. If you decide to do this yourself, follow the step-by-step instructions:
- Disconnect the refrigerator unplug and wait for complete defrosting (at least 12 hours).
- Remove the back panel chamber where the faulty fan is located. In the freezer it is usually fastened with screws, in the refrigerator compartment - with latches.
- Disconnect the power connector from the fan. Remember or photograph the location of the wires.
- Remove the mounting bracket (it can be screwed or secured with plastic clips).
- Install the new fan and connect it to the connector. Make sure that the blades rotate freely.
- Assemble the refrigerator in the reverse order and turn it on.
Original fans are suitable for replacement Atlant or analogues from manufacturers EBM-Papst, Sanyo Denki. The main thing is matching in size and voltage (usually 12 or 24 V). The average cost of a new fan is 1,500–3,000 rubles.
⚠️ Attention: When installing a new fan, do not mix up the polarity of the connection. If there are markings+i–on the connector, follow them. Otherwise, the motor may burn out when you turn it on for the first time.
After replacing, let the refrigerator run for 1-2 hours in an empty state to make sure the system is working properly. If the temperature in the chambers has returned to normal and extraneous sounds have disappeared, the repair was successful.
Common causes of fan failure and how to avoid them
Fans in refrigerators Atlant fail for several typical reasons. Knowing them, you can extend the service life of the unit:
- 🧊 Freezing of the blades - occurs due to a faulty defrost heater or sensor. Regular defrosting (once every 6 months) helps to avoid the problem.
- 🔋 Wear of bearings —over time, the lubricant dries out and the motor shaft begins to jam. Only replacement helps.
- ⚡ Power surges —lead to winding burnout. Use a voltage stabilizer for protection.
- 🛠️ Mechanical damage — if disassembled carelessly, the blades can break. Always turn off the power before work.
To minimize the risk of breakdown:
- Do not overload the freezer with products that block the ventilation holes.
- Regularly clean the back wall of the refrigerator from dust (it clogs the motor).
- Do not place the refrigerator close to the wall - there must be a distance of at least 5 cm for air circulation.
If your refrigerator Atlant was produced before 2018, please note that in older models the fans may have had less reliable bearings. In this case, it is recommended to purchase a spare unit in advance.
FAQ: Frequently asked questions about fans in Atlant refrigerators
Is it possible to operate the Atlant refrigerator without a fan?
No, this will lead to uneven cooling and increased load on the compressor. In models with NoFrost without a fan, the freezer will work, but the refrigerator will not. In the long run, this will damage the compressor.
How to check if the fan is working without disassembling the refrigerator?
Put your hand near the ventilation holes between the chambers or on the back wall. If there is no air flow and the refrigerator is humming, the fan is faulty. You can also put your ear to the back panel: a running fan makes a uniform noise.
How much does it cost to replace a fan at a service center?
The cost of replacing a fan at a service center varies from 3,000 to 6,000 rubles (including spare parts). If you buy the part yourself (1,500–3,000 rubles) and do the replacement yourself, you can save up to 50%.
Why does the fan in the Atlant refrigerator work constantly?
Continuous operation of the fan may be due to a malfunction of the temperature sensor, control board or freon leak. Normally, the fan should be turned off periodically along with the compressor.
Is it possible to lubricate the Atlant refrigerator fan if it squeaks?
Lubricating bearings is only possible in dismountable fan models (which is rare). In most cases, the motors are non-separable, and lubrication will not help - they will need to be replaced. An attempt to lubricate a non-separable bearing can lead to oil getting on the winding and a short circuit.
