The situation when food is in the refrigerator Indesit stop freezing or cooling properly, is familiar to many owners of household appliances. Instead of hard briquettes, a soft porridge forms in the freezer, and the milk in the main compartment sours faster than expected. This is not just an inconvenience, it is a risk of spoilage of food supplies and loss of the family budget.
Before calling a specialist or thinking about buying a new unit, it is worth conducting a thorough diagnosis yourself. In most cases, the problem lies in improper operation, violation of loading rules, or incorrect settings of the thermostat. However, technical malfunctions that require the intervention of a specialist cannot be ruled out.
In this article we will examine in detail why the Indesit refrigerator does not freeze well what can be done at home. We will go from simple manipulations of the thermostat knob to complex checks of the refrigerant circulation system. Understanding the operating principles of your model will help you quickly return the unit to working order.
Checking and adjusting the thermostat settings
The most commonplace, but often ignored reason is incorrect temperature settings. If you have recently defrosted the unit or simply touched the handle, it may have moved to the minimum cold position. In models with mechanical control, this is a round regulator with numbers from 1 to 5 or 7.
It is important to understand that the number on the scale does not mean degrees Celsius. This is the conditional power of the compressor. The higher the number, the the motor works more intensely and the colder it is inside the chambers. If the handle is set to one, the unit may simply not cope with the load, especially in summer or when fully loaded.
For electronic models Indesit with a display (Push&Go or Smart series), the situation is similar, but control is carried out by buttons. Here it is important to check whether the “Eco” or “Vacation” mode is activated, which specifically maintain a higher temperature to save energy.
- 🌡️ Set the mechanical regulator to the average value (usually 3 or 4) and wait a few hours for stabilization.
- 🔢 For models with a display, set the temperature in the main chamber to +4...+5°C, and in freezer -18°C.
- 🔄 If, after turning the knob to maximum, the cold does not appear within 24 hours, the problem is not in the settings.
Do not immediately turn the knob to maximum. Operating the compressor at the limit of its capabilities unnecessarily will lead to its rapid wear and formation of an ice coat, which itself will become a barrier to cold.
⚠️ Attention: If you turn the regulator to maximum, and the compressor runs continuously without turning off, but the cold does not appear, this is a sure sign of a freon leak or a compressor malfunction. Further operation in this mode is dangerous due to overheating of the motor.
The influence of loading and air circulation on cooling
A refrigerator is not a warehouse, but a complex thermodynamic system. For effective operation, the air mass must circulate freely inside the chambers. If you tightly fill the shelves with products, especially at the back wall, air circulation the air circulation is broken.
In models Indesit with the No Frost or Low Frost system, cold air is supplied through special channels. If these holes are blocked by pots or bags, the temperature sensors will not receive correct readings. The compressor thinks that it is warm inside and works non-stop, but the actual cooling of the products does not occur due to the lack of convection.
The condition of the products you load is also critically important. Do not place hot or even warm food in the chamber. The evaporation of moisture from hot food sharply increases the humidity, which leads to freezing of the evaporator. The ice crust on the evaporator acts as a heat insulator, preventing cold from penetrating into the chamber.
Check that food is not sticking to each other or to the walls. If yes, then the air flow is blocked. Clear the ventilation holes, often located on the back panel or at the top of the chamber.
Diagnostics of sealing rubber and tightness
One of the common causes of loss of cold is depressurization of the chamber. Over time, the rubber seal on the door dries out, cracks, or simply becomes contaminated with grease. Warm air from the kitchen enters through microscopic cracks, causing the unit to wear out.
Carry out a visual inspection of the rubber around the entire perimeter. There should be no cracks, tears or sticky residue on it. If the rubber is just dirty, you can wash it with warm water and a mild detergent. If it becomes stiff, try gently warming it with a hairdryer to restore elasticity.
There is a simple leak test. Take a regular sheet of paper, clamp it with the refrigerator door and try to pull it out. If the sheet is easily removed without resistance in different places around the perimeter, it means the seal does not fit tightly.
| Symptom | Probable cause | Elimination method |
|---|---|---|
| Ice around the perimeter doors | Tightness failure | Replacing or restoring the seal |
| The compressor hums constantly | Inflow of warm air | Checking the door fit, adjusting the hinges |
| A sheet of paper falls out | Rubber wear | Replacing the sealing collar |
| The door is skewed | Loose hinges | Adjusting fasteners bolts |
If the seal is physically worn out, no temperature settings will help. Warm air will flow faster than the refrigerator can cool it. In this case, the cuff needs to be replaced.
☑️ Checking the tightness
Defrosting: when it's really needed
Even modern systems No Frost sometimes fail, and drip models require regular attention. If you haven't defrosted your refrigerator for a long time Indesit, a thick layer of ice may have formed on the evaporator. This ice blocks heat exchange.
In drip systems (“Weeping Wall”), water flows into a groove and evaporates. If the drainage hole is clogged with crumbs or ice, the water freezes, forming a snowdrift. This snowdrift blocks the access of cold to the products. Visually, this may look like ice on the back wall of the main chamber.
To completely defrost, you must unplug the unit for at least 10-12 hours. Simply turning it off for an hour is not enough - the ice inside the case needs time to completely melt. The doors must be open.
⚠️ Attention: It is strictly forbidden to chip off the ice with a knife, screwdriver or other sharp objects! You can break through the evaporator, and then a freon leak will become a fact. Repairs after such “intervention” will be very expensive.
After defrosting, wipe the chambers dry and turn on the refrigerator empty. Allow it to reach temperature for 2-3 hours before adding food. This will allow the system to stabilize.
Why did the cold become even less after defrosting?
If after a long defrosting (more than 24 hours) and subsequent switching on the cold does not appear, this indicates a technical malfunction, and not the need for defrosting. Most likely, the problem is in the compressor or refrigerant leak.
Technical malfunctions: freon leak and compressor
If all of the above methods did not help make the refrigerator colder, we are talking about a serious breakdown. Most often in units Indesit there is a refrigerant (freon) leak. This may occur due to corrosion of tubes or microcracks in the circuit.
If there is a leak, the compressor works constantly, trying to catch up with the temperature, but there is not enough refrigerant in the system, and there is no cold. A common symptom is a hot capacitor (grid at the back) only partially or only near the motor, and the rest is cold. Another problem is the failure of the start relay itself. The engine may hum, click, but not start, or start for a couple of seconds and stall. In this case, replacement of the unit is required.
Another problem is the failure of the compressor or start relay. The engine may hum, click, but not start, or start for a couple of seconds and stall. In this case, replacement of the unit is required.
Diagnostics of these problems requires special equipment: pressure gauges, leak detectors and a vacuum pump. It is impossible and dangerous to fill the system with freon on your own.
The influence of external factors and the location of the refrigerator
Sometimes the problem lies not inside, but outside. The location of the refrigerator Indesit plays a key role. If the unit is located close to the wall, in a niche or next to a radiator, stoves or oven, heat transfer is disrupted.
The condenser must be freely blown with air. The minimum distance from the back wall to the kitchen wall should be at least 5-7 centimeters. If space is limited, cooling efficiency drops and it becomes impossible to lower the temperature.
It is also worth considering the room temperature. If the kitchen is hot (above +30°C), the refrigerator may physically not be able to maintain the set parameters, working at the limit of its capabilities.
- ☀️ Do not install the refrigerator in direct sunlight.
- 🔥 Avoid proximity to heating devices (radiators, stoves).
- 💨 Ensure free air access to the rear radiator grille.
Check whether the sides of the case are getting hot. Slight heating of the sides is normal for modern models, where heat is dissipated through the walls. But if they get hot, it means the system is overloaded.
What to do if the refrigerator is in a cold room?
Most refrigerators Indesit are not designed to operate at temperatures below +10°C. Under such conditions, the oil in the compressor thickens, and the thermostat may not turn on the motor, since the room is already cold. Operation on an unheated balcony or in a garage in winter is prohibited by the instructions.
Is it possible to increase the cold with a fan?
Some users place a small USB fan inside the camera for circulation. This is risky due to humidity and condensation, which can cause a short circuit. It is better to establish natural convection with the correct loading.
Why is there cold in the freezer, but not in the refrigerator?
This is a classic sign of a “crying” evaporator or a clogged capillary. Cold is produced, but does not reach the main chamber. It is also possible for the air duct damper to stick in No Frost models.
How often should the seal be changed?
The service life of the seal is 5-7 years. If it has become hard, lost color or no longer holds the magnet, it needs to be changed, even if there are no visible breaks.
Does the amount of food affect the cooling rate?
Yes, a full refrigerator keeps the cold better, since the products work as cold accumulators. However, an empty refrigerator will gain temperature faster after opening the door, but it will also cool new products more slowly due to the large volume of air.
