Search fan in the refrigerator Pozis is a standard procedure when there is extraneous noise or a complete lack of cooling in the chambers. The owner of household appliances often encounters a humming, creaking or crackling sound produced by the evaporator blower motor. Understanding the exact location of this unit is critical for correct diagnosis of the malfunction and subsequent repair.
In most modern models Pozisequipped with the system No Frost, the blower element is hidden behind decorative panels. You won't be able to get to it without removing the back wall of the freezer. The design of refrigerators of this brand implies that air circulation is forced, which means that the serviceability of the fan directly affects the temperature in all compartments of the unit.
Before proceeding with disassembly, you must disconnect the device from the power supply. This is a basic safety rule and, if ignored, may result in electric shock or short circuit if the wiring is accidentally damaged. Next, you should determine what type of cooling system your model belongs to, since the location of the components may differ slightly.
Design features of the Pozis cooling system
Refrigerators Pozis, like most modern units, are divided into models with a drip defrosting system and a system No Frost. The cooling fan is present exclusively in the latter. If in your refrigerator there is an evaporator grille protruding on the back wall of the main chamber and there are no air channels, then it is pointless to look there supercharger it is not there by design.
In models Pozis series RDH, RSH or BIN with technology No Frost the fan is usually located in the freezer compartment. It is attached directly to the evaporator casing, which, in turn, is hidden behind a plastic panel on the rear wall of the chamber. The task of this mechanism is to drive cold air from the evaporator through the air ducts into the refrigerator compartment and back.
There are also models with a double circulation system, where two separate fans can be used: one for the freezer, the other for the refrigerator compartment. However, in classic two-chamber refrigerators Pozis most often one powerful motor is installed in the upper part of the freezer, distributing flows along both circuits.
⚠️ Attention: An attempt to start the refrigerator with the back panel of the freezer compartment removed can lead to frostbite on exposed skin and damage to plastic elements due to direct contact with the ice evaporator.
Correct operation heat removal systems depends not only on the serviceability of the motor itself, but also on the condition of its blades. Models Pozis often use a plastic impeller, which over time can become deformed from the cold or become covered with an ice crust if the defrosting system does not work correctly.
Exact location in the freezer
To find fanopen the freezer door. Visually you will only see shelves and drawers. The mechanism is hidden under the back wall. Depending on the series Pozis (for example, Shivaki or Pozis own production), access can be organized in different ways. Most often, you need to remove all the shelves and the top drawer.
The back panel is secured with plastic latches or screws. In some modifications Pozis the screws may be hidden under decorative plugs or located inside the drawer niche. After carefully dismantling the panel, you will have a view of the aluminum the evaporator and the electric motor mounted on it.
Itself motor usually located in the upper or central part of the evaporator. It can be closed with an additional plastic box or casing that directs the air flow. Fastening is carried out either directly to the radiator tubes, or to a special mounting frame.
- 🔍 Top location: Found in high models Pozis, where the fan is installed at the very top of the evaporator niche.
- 🛠️ Central mount: Characteristic of classic two-chamber refrigerators, where the motor is located in the center of the radiator.
- ❄️ Protective cover: Often the engine is covered with white or transparent plastic, which must be removed to access the impeller.
When inspecting, pay attention to the condition of the wiring. Cables going to motorshould not have any creases or traces of melting. In models Pozis the wiring often runs in close proximity to the defrost heating element, which, if the thermostat malfunctions, can lead to damage to the insulation.
Algorithm for accessing the fan
Process of gaining access to supercharger requires a sequence of actions. First, all food, shelves and containers are removed from the freezer. Then the plastic back panel is removed. If it is frozen, you cannot use force - you need to wait for defrost or carefully warm the edges with a hairdryer at the minimum temperature.
After removing the panel, access to evaporatoris gained. The fan can be mounted with 2-4 screws or held on with plastic clips. Models Pozis typically use Phillips screws. Before unscrewing, it is recommended to photograph the wiring diagram.
To remove the mechanism itself, it is often necessary to disconnect the power connector. It can be located directly next to the motor or placed on the body of the refrigerator. Be careful: plastic becomes brittle in the cold, and careless movement can break connector latches.
☑️ Disassembly procedure
If the fan is jammed with ice, do not try to forcefully rotate it. This may damage the bushings or bearing. It is better to defrost the unit naturally. In some cases, a complete replacement of the assembly is required if the bearings have exhausted their service life.

On the evaporator tubes
| Element | Location in Pozis | Function | Malfunction symptom |
|---|---|---|---|
| Evaporator fan | Freezer compartment, behind the back wall | Cold air circulation | Noise, lack of cold |
| Evaporator | Behind the rear panel of the freezer | Air flow cooling | Ice, lack of cold |
| Heating element defrosting | Ice melting | Increasing "coat" of ice | |
| Defrost sensor | Defrosting temperature control | Frequent activation of heating elements or their absence |
Diagnostics of fan malfunctions
The main sign of breakdown fan in the refrigerator Pozis is the appearance of extraneous sound. This may be a hum, crackling, grinding or periodic clicking. If the sound changes when the door is opened, this often indicates that the problem is in the blower motor, since in many models it should turn off when the door is opened.
The second important symptom is insufficient cooling. If the compressor runs continuously and the temperature in the chambers does not drop to the set values, the fan may not be spinning and not moving cool air. You can check this by listening to the operation of the unit: if there is no hum from the blower motor, but the compressor is humming, there is a malfunction.
The third sign is the formation of an ice plug in the air ducts. If circulation is disrupted, moisture is not removed from the system and freezes in the channels, blocking the access of cold to the refrigerator compartment. This often happens when the fan impeller becomes covered with ice and stops rotating at the required speed.
⚠️ Attention: Operating the refrigerator Pozis with a non-working fan leads to overheating of the compressor. Long-term operation in this mode can damage the main unit, the repair of which costs much more than replacing the fan.
For accurate diagnostics, you can apply voltage to the motor contacts (observing polarity and voltage, usually 220V or 12-24V depending on the model). If, when power is applied, the shaft does not rotate or rotates with difficulty and noise, it requires replacement of the unit..
Can the fan be lubricated?
Theoretically, the plain bearing can be lubricated, but in practice, in refrigerator conditions, the lubricant quickly thickens or freezes. The effect will be temporary (from a week to a month), after which the noise will return with renewed vigor. A complete replacement is recommended.
Replacement and maintenance of the blower motor
If diagnostics confirm a malfunction, you need to purchase a new one fan. For refrigerators Pozis universal models or original spare parts with markings EBM, DC or analogues are often suitable. It is important that the geometric dimensions, voltage and direction of rotation of the blades match.
The replacement process begins with dismantling the old engine. Disconnect the connector, unscrew the mounting screws and remove the assembly. When installing a new fan, make sure that the blades do not touch the walls of the casing. The gap should be minimal, but without contact, otherwise a whistling sound will appear whistling sound.
During assembly, it is important to lay the wires correctly. They must not touch moving parts or heating elements. Models Pozis often use special plastic clips to fix the harnesses that need to be returned to their place.
- 🧹 Cleaning: Before installing a new fan, clean the evaporator niche from dirt and ice residues.
- 🔧 Fixture: Use only standard screws or their exact analogues, so as not to damage the threads in plastic.
- 🔌 Contact: Check the reliability of the connector connection - oxidation of the contacts can cause malfunctions.
After replacement, reassemble the refrigerator in the reverse order. Plug in the unit and check operation No Frost systems. After 15-20 minutes of operation, a steady flow of cold air should appear from the channels of the refrigeration chamber.
Frequently asked questions and answers
Why does the fan in the Pozis refrigerator only work when the door is closed?
This is the normal operating mode for most models with the system No Frost. The design provides for the opening of the fan power circuit when the door is opened, so that cold air is not blown into the room, as well as for the safety of the user. If the fan continues to work when the door is open, the door limit switch may be faulty.
Is it possible to temporarily remove the fan and use the refrigerator?
Theoretically, the refrigerator will cool, but only in the freezer and very inefficiently. The cold will stop flowing into the refrigerator compartment, food will begin to deteriorate, and the compressor will work without interruption, trying to gain temperature. This will lead to its rapid wear and increased energy consumption.
How to distinguish fan noise from compressor noise?
Noise compressor is a low-frequency hum or rumble that is felt by the vibration of the case. Noise fan is a high-frequency whistle, crackling or hum, reminiscent of the operation of a computer cooler. Sound localization also helps: the compressor is located at the bottom at the back, and the fan is inside the freezer.
Is it necessary to lubricate the old fan instead of replacing it?
Lubricating the bearings in the refrigerator fan Pozis is a temporary and often ineffective measure. The specific nature of operation at low temperatures requires special frost-resistant lubricants. Regular oil will freeze and the noise will return. Considering the affordable cost of a new motor, replacement is a more rational solution.
