A noisy fan in the refrigerator Indesit is one of the most common problems faced by owners of equipment older than 5 years. Extraneous sounds, creaks or hums are not only annoying, but also indicate increased wear of parts. In 80% of cases, the reason lies in dry or contaminated bearing greasewhich can be restored independently without calling a technician.
Many users are afraid to disassemble the refrigerator for fear of damaging the cooling system or breaking the seal. However, fan lubrication is one of the simplest proceduresnot requiring special skills. The main thing is to choose the right lubricant, follow the sequence of actions and do not forget about safety precautions. In this article we will analyze the entire process in detail: from fault diagnosis to final assembly.

Signs that the fan needs lubrication
The first signal of problems with the fan is change in the nature of the noise. The new refrigerator Indesit operates almost silently, emitting only a slight whirring of the compressor. If squeaks, crackles or periodic hums appear over time, this is a reason to check the condition of the bearings.
Other symptoms indicating the need for lubrication:
- 🔊 Cyclic noise —the sound appears and disappears (especially noticeable when opening/closing the door).
- 🌀 Vibration of the body —the refrigerator slightly “shakes” during operation, although this has not been observed before.
- ❄️ Uneven cooling —in some areas the temperature is higher than normal (the fan unevenly distributes cold air).
- 🕒 Increasing operating time —the compressor turns on more often and cools longer.
It is important to distinguish fan problems from compressor malfunctions or freon leaks. If the refrigerator Indesit not only makes noise, but also poor freezingthe reason may be more serious. In this case, lubricating the fan will not help - comprehensive diagnostics will be required.
⚠️ Attention! If noise is accompanied burning smell or smokeimmediately unplug the refrigerator. This may indicate a short circuit in the fan motor or compressor winding.
Which lubricant to choose for a refrigerator fan
The wrong choice of lubricant is the main mistake of beginners. Regular machine oils or WD-40 not suitable for fan bearings: they dry out quickly, attract dust and can damage plastic parts. For refrigerators Indesit recommended:
| Lubricant type | Examples of brands | Pros | Cons |
|---|---|---|---|
| Silicone | Dow Corning Molykote 111, Klüber Isoflex Topas NB 52 | Does not dry out, is resistant to low temperatures, does not react with plastic | More expensive than mineral analogues |
| Lithium | Liqui Moly Lithoflux, Castrol LMX | Good adhesion, long service life | Can thicken at -20°C and below |
| Teflon | DuPont Krytox 240AC, Super Lube | High temperature resistance, does not attract dust | Difficult to find in regular stores |
| Specialized for refrigerators | Electrolube HTS, NyoGel 760G | Designed for low-temperature bearings | High price |
For most models Indesit (for example, C 132 G, TN 3301, BIAA 13) the optimal choice is silicone grease. It does not lose properties at temperatures from -40°C to +200°C and does not harm seals. A tube volume of 5–10 ml is enough to treat 2–3 bearings.
⚠️ Attention! Never useWD-40,solidolorgraphite grease. These compounds destroy the plastic fan bushings and cause it to jam.
Preparing the refrigerator for repair
Before disassembling, be sure to unplug the refrigerator and wait until it is completely defrosted (if the model is with No Frost). This will take 6–12 hours. Do not try to speed up the process with a hair dryer or hot water - a sudden temperature change can damage the seals.
Preparation checklist:
Remove all products and shelves|Unplug the refrigerator|Wait for complete defrosting (6+ hours)|Prepare tools (screwdrivers, pliers)|Wear gloves and safety glasses-->
Tools you will need:
- ⚒️ Phillips and flathead screwdrivers (for removing the back panel).
- 🔧 Pliers or pliers (for fixing fan during disassembly).
- 🧴 Syringe with a needle (for precise application of lubricant).
- 🧼 Cotton swabs and alcohol (for cleaning bearings).
- 📸 Phone or camera (to photograph the location of parts before disassembly).
If your refrigerator Indesit with a system No Frost, the fan is located behind the back wall of the freezer. In models with a drip system (Direct Cool), it can be located at the bottom of the rear panel. The exact location is indicated in the operating instructions.
Where to look for the instructions for the Indesit refrigerator?
If the paper instructions are lost, find the electronic version on the official Indesit website in the "Support" section. Enter your refrigerator model (located on a sticker inside the chamber or on the back wall) and download the PDF file. An alternative is a service ManualsLib, where manuals for equipment of different brands are collected.
Step-by-step instructions for lubricating the fan
Begin disassembling the refrigerator only after complete defrosting and drying of the internal surfaces. Follow the algorithm:
- Removing the back panel
Unscrew the screws securing the back cover (usually 4-6 pieces). In models Indesit No Frost the panel can be attached with latches - carefully pry it off with a flat screwdriver. Do not use excessive force to avoid breaking the plastic.
- Localization of the fan
The fan looks like a small plastic propeller on a shaft with an electric motor. In refrigerators Indesit it is most often black or gray. Before disassembling, take a photo of its position and wire connections.
- Cleaning the bearings
Remove the fan blades by pulling them towards you (sometimes you need to pry the latches with a screwdriver). The bearings are usually hidden under a plastic cover. Remove old grease with a cotton swab dipped in alcohol. Do not use acetone or gasoline - they corrode the plastic!
- Applying new grease
Fill the syringe with silicone grease and carefully inject 2-3 drops into each bearing. Rotate the fan shaft by hand to distribute the mixture. Remove excess lubricant with a napkin.
- Assembly and testing
Install the blades back, secure the fan and return the back panel to its place. Connect the refrigerator to the network and check the operation: the noise should disappear or decrease significantly.
Common mistakes and how to avoid them
Even with the apparent simplicity of the procedure, many make mistakes that lead to fan breakdown or deterioration in its performance. Here are the most common:
- 🛠️ Overuse of lubricant — excess composition leads to its squeezing onto the blades and dust adhesion. 2-3 drops per bearing is enough.
- 🔌 Incorrect assembly —if you reverse the polarity when connecting the wires, the fan will rotate in the opposite direction, which will disrupt air circulation.
- ❄️ Operation without defrosting —ice on the blades can damage them when rotating after switching on.
- 🧴 Use of unsuitable lubricant —for example,
Litol-24thickens at low temperatures and blocks the shaft.
Another typical problem is incomplete cleaning of bearings. If you leave old thickened grease inside, the new one will not be able to distribute evenly, and the effect will be temporary. Use alcohol or a special cleaner Kontakt 60 to remove residues.
⚠️ Attention! If after lubrication the fan begins to rotate jerkily or makes a metallic grinding noise, this is a sign bearing wear. In this case, the entire engine will need to be replaced.
Prevention: how to extend the life of the fan
Lubricant solves the problem here and now, but to avoid repeated malfunctions, follow simple maintenance rules:
- 🧊 Regular defrosting —even for models No Frost it is recommended to defrost the refrigerator 1-2 times a year. This prevents ice from accumulating on the blades.
- 🧹 Cleaning the back wall —dust and cobwebs on the engine impair heat dissipation. Remove dirt with a vacuum cleaner or soft brush.
- 🌡️ Temperature control —do not install the refrigerator near heat sources (radiators, stoves). Overheating shortens the life of the bearings.
- 🔄 Checking the seals — worn rubber gaskets on the door lead to icing of the fan.
For models Indesit with a system Total No Frost (for example, BIAA 24 or TIA 26), pay special attention to cleaning the drainage hole. A clogged drain leads to the accumulation of condensation and corrosion of metal parts of the fan.
When lubrication does not help: signs of serious damage
If after all the manipulations the fan continues to make noise or does not rotate at all, the problem may be deeper:
| Symptom | Possible reason | Solution |
|---|---|---|
| The fan does not rotate, but hums | Seized bearing or burnt motor winding | Replacing the fan motor |
| The blades rotate jerkily | Wear of the shaft bushings or damage to the winding | Diagnostics with a multimeter, replacement of parts |
| The noise increases over time | Deformation of the blades or imbalance | Replacing the propeller or the entire fan |
| The fan works, but the refrigerator does not cool | Faulty sensor or control board | Electronics diagnostics |
In models Indesit with electronic control (for example, EWT 27151), a fan malfunction may be accompanied by error code on the display. Look for decoding of the codes in the instructions or on the official website. For example, an error F04 often indicates problems with the fan motor.
⚠️ Attention! If you are not confident in your electronics diagnostic skills, do not take risks - contact a service center. A short circuit due to improper repairs can damage the control board.
FAQ: Answers to frequently asked questions
Is it possible to lubricate the fan without disassembling the refrigerator?
No, high-quality lubrication requires direct access to bearings. Through the technological holes (if any) you can only temporarily reduce the noise, but complete cleaning and lubrication will not be possible.
How often do you need to lubricate the fan in the Indesit refrigerator?
Under normal operating conditions - once every 3-5 years. If the refrigerator operates in conditions of high humidity or dust, the interval is reduced to 2 years.
What to do if, after lubrication, the fan begins to make more noise?
Probably, grease got on the blades or the bearings were not cleaned well enough. Disassemble the fan again, remove excess compound and check the balancing of the blades.
Can edible oil be used for lubrication?
Absolutely not! Edible oils quickly oxidize, thicken and attract dust. This will lead to jamming of the fan within a few months.
Where to buy an original fan for Indesit if you need to replace it?
Original spare parts are sold at branded Indesit service centers or at sites like eBay, AliExpress (search by the part code indicated on the fan sticker). An alternative is universal fans of a suitable size.
