The situation when the refrigerator Indesit after complete defrosting and restarting starts working without interruption, causing natural panic among owners. It seems that the equipment is out of order, the compressor is about to burn out, and the food is going to spoil. However, in most cases, a long operating time in the first hours after switching on is the normal operating mode of the system, and not a sign of a breakdown.
The fact is that heat exchange the inside of the chambers is disturbed due to the lack of cold, and the walls and shelves are at room temperature. The unit requires considerable time to cool the entire internal volume and freeze the food that you returned there. Only after reaching the specified temperature values thermostat or the electronic module will give a command to stop the engine.
It is important to understand the physics of the process: the compressor cannot instantly produce cold, it needs time to enter operating mode. If you have loaded the chambers with warm products, the operating time may increase significantly. Let's look in detail at how long this process takes and when to sound the alarm.
Normal operating time of the compressor after switching on
According to the technical characteristics of most models Indesit, the first cooling cycle after defrosting can last from 6 to 12 hours. This time is necessary to freeze out the heat accumulated by the housing and the contents of the chambers. During this period, the compressor works almost without interruption, and this is absolutely normal.
If the temperature in the refrigerator compartment is set at +4°C, and in the freezer -18°C, the system needs time to stabilize. This process takes especially long if you defrosted the unit for more than 24 hours or washed it with warm water. The walls could have warmed up, which increased the thermal load on the system.
In normal operation, when the refrigerator has already reached the temperature, it should turn off. The operating cycle of a working device is usually: 15-20 minutes of operation and 30-40 minutes of rest. However, immediately after switching on, there may be no rest period at all.
⚠️ Attention: If the refrigerator operates for more than 24 hours without a single break to stop the compressor, and the temperature inside the chambers does not drop to the set values, this indicates a malfunction or violation of operating rules.
You should not try to artificially speed up the process by setting the minimum possible values on the regulator. This will create excess load on refrigerant and the motor, but will not speed up the cooling of the products. Give the equipment time to reach the mode on its own.
Factors influencing the duration of the first cycle
Many variables influence how long it will work Indesit after defrosting. Not all of them are related to the technical condition of the device. Often the user himself increases the operating time by making errors when loading.
The key factor is the volume and temperature of the loaded products. If you put large amounts of room temperature food, or worse, warm food, into the chambers, the refrigerator will have to work harder. Thermal products will give off energy that the system must remove.
Load density is also important. An empty refrigerator cools down faster than a completely full one. The air circulates more freely and the cold is distributed more evenly. If the chambers are packed tightly, the time of the first cycle can be extended to the maximum.
- ❄️ Room temperature: If the room is hot (above +25°C), heat exchange with the environment is difficult, and the compressor will work longer.
- 🥩 Temperature of products: Loading warm or hot products significantly increases the operating time until the first shutdown.
- 🚪 Frequency of door openings: Constantly looking inside in the first hours disrupts the temperature regime and interferes with stabilization.
Another important aspect is the correct installation. If the refrigerator is located close to the wall or in a niche without gaps for ventilation, the heat from the condenser does not have time to dissipate. This leads to overheating of the system and increased operating time.
The influence of the type of cooling system No Frost and drip
Models Indesit can be equipped with different defrosting systems, and this directly affects the behavior of the compressor. In refrigerators with a No Frost system (or Low Frost), the process may take longer due to a more complex system of air ducts and evaporators hidden behind plastic panels.
In units with a drip system (Drop System), cooling occurs due to contact with the rear wall. It is important here that the products do not fit tightly to the back panel, otherwise the temperature sensor may incorrectly read the data, and the compressor will work longer than necessary.
In No Frost systems, the fan plays an important role. It should drive cold air through all channels. If, after defrosting, you did not allow the water to completely evaporate from the pan or drainage system, this may temporarily disrupt air circulation.
| System type | Features after defrosting | Average operating time before 1st shutdown |
|---|---|---|
| Drip (Static) | Cooling through the rear wall, condensation is possible | 6–10 hours |
| No Frost | Cold air circulation, dryness in the chambers | 8–14 hours |
| Combined | No Frost in the freezer, drip in the refrigerator compartment | 8–12 hours |
It is worth noting that in No Frost models, temperature sensors are often located in the evaporator area, and not in the main chamber. Therefore, even if the food compartment is already cold, the compressor can continue to work to cool the evaporator itself and start the defrost cycle in the future.
Rules for loading food after defrosting
One of the most common reasons why the refrigerator Indesit does not turn off is incorrect initial loading. Many users make the mistake of filling the chambers immediately after switching on, without waiting for the temperature to rise.
The heat contained in food is a powerful source of heating. One liter of water or meat at room temperature contains an enormous amount of thermal energy compared to the volume of air in the chamber. The compressor is forced to work hard to compensate for this heat influx.
☑️ Rules for loading the refrigerator
In addition, it is important to maintain tightness. If you often open the door in the first hours to check if it is “frosted,” you let in warm, moist air. This not only resets the cooling progress, but also contributes to the formation of a new ice crust on the evaporator.
It is recommended to use the "Super Freeze" mode (if your model has it, indicated by a snowflake or button Super Freeze) only for a short time (2-4 hours) to quickly gain cold, but do not leave it on constantly, as this blocks automatic shutdown.
When long operating time is a sign of breakdown
Despite the fact that long operating time after defrosting is the norm, there are signs that indicate a real malfunction. If more than a day has passed, and the refrigerator Indesit buzzes continuously and does not freeze (or freezes weakly), the problem lies in the equipment.
A common cause is freon leak. There is not enough refrigerant to create the required pressure, the compressor works constantly, trying to increase the temperature, but cannot do this. In such cases, the freezer may work, but the refrigerator compartment may not.
Another reason is a malfunction of the thermostat or temperature sensor. If the sensor is stuck or transmits incorrect data that the chamber is warm, the control module will keep the compressor on indefinitely. It is also possible for the sensor to freeze in No Frost systems.
⚠️ Attention: If the condenser (rear grille or side walls) remains cold or barely warm during long operation of the compressor, this is a sure sign of a refrigerant leak or a problem with the compressor.
Clogged capillary tube is another technical problem. The circulation of freon in the system is disrupted, the pressure rises, but there is no cold. In this case, a characteristic gurgling sound is often heard or, conversely, silence when the engine is running.
Hidden signs of malfunction
If you hear relay clicks when the engine is running, but it does not start or stalls immediately, there may be a problem with the start relay or the compressor itself. This requires calling a technician.
Diagnostics and actions if there is no shutdown
What to do if the refrigerator Indesit has been working for the second day? First of all, you need to carry out an initial diagnosis on your own to understand whether you need to call a specialist. Start by checking the temperature.
Use an external thermometer, placing it in a glass of water in the center of the refrigerator compartment. This will give an objective picture, since built-in sensors may show incorrect data. If within 24 hours the temperature has not dropped below +10°C in the refrigerator compartment, there is a problem.
Check the integrity of the door seals. If the rubber is dry or torn, the cold goes away and the compressor runs idle. A simple test with a piece of paper pressed against the door will help identify a loose seal around the perimeter.
- 🔍 Visual inspection: Check for oil stains under the refrigerator or on the back wall (a sign of leakage).
- 👂 Audio diagnostics: Listen to the sound of operation. A uniform hum is normal, intermittent, with a knock or whistle - a sign of a breakdown.
- 🌡️ Checking the heating: The capacitor must be warm or hot. If it is cold when the engine is running, there is no freon circulation.
If you find obvious signs of a malfunction, further operation may lead to combustion of the compressor. In case of doubt, it is better to contact a service center, especially if the equipment is under warranty.
How long exactly should the refrigerator wait after defrosting before turning it on?
The minimum idle time when turned off with the doors open is 8-10 hours for the ice to completely melt. Before connecting to the network after washing or transportation, it is recommended to let the equipment stand for 2-4 hours so that the oil in the compressor stabilizes and the moisture dries.
Is it possible to turn on the refrigerator immediately after defrosting without waiting?
It is absolutely not possible. Turning on the appliance with water or ice remaining in the drainage system may result in a short circuit. In addition, a sharp start of the compressor after idle time without equalizing the oil pressure can cause water hammer and breakdown of the unit.
Why does the Indesit refrigerator hum, but does not freeze after defrosting?
If the motor hums, but there is no cold, this indicates that the compressor is working, but freon is not circulating. Possible causes: gas leak, clogged capillary system or malfunction of the compressor itself (loss of performance). Repair is required.
Do I need to set the maximum cold immediately after switching on?
No, this is an error. Set the control to the middle position (usually 3 or 4 out of 7). The maximum mode will create extra load. It is better to let the system gain temperature in normal mode, and then, if necessary, adjust the settings.
