The question of how exactly the refrigerator should be turned off Indesitoften arises not only when moving or general cleaning, but also at moments when the equipment begins to behave strangely. Many owners confuse a normal compressor shutdown with an emergency stop or a thermostat malfunction. Understanding the difference between normal operation and breakdown is the key to preserving products and extending the life of the unit.
Modern models, such as Indesit DS 320 or older versions with mechanical control, have their own characteristics of engine operation. Incorrect interpretation of sounds or pauses in operation can lead to inventory spoilage or, conversely, to ignoring a serious breakdown. In this article we will analyze the physics of the shutdown process, algorithms of actions during planned and emergency shutdowns, as well as typical mistakes that users make.
It is important to immediately note that cyclical operation is a normal phenomenon. However, the length of the cycles and the nature of the sounds when stopping can tell a lot about the condition of the refrigerant and compressor. If you notice that your Indesit turns off too often or, conversely, works without interruption, this is a signal for diagnosis. Let's look at what is considered normal and what requires the intervention of a specialist.
⚠️ Attention: If you smell burning, hear a loud crackling sound or see sparking in the compressor area, immediately unplug the cord from the outlet. Further operation in this mode may lead to a fire in the wiring.
Normal operating cycle and signs of service
A working refrigerator Indesit operates in a cyclic mode, which depends on the set temperature, the ambient temperature in the room and the amount of food inside the cameras. Normally, the compressor turns on, builds up pressure, cools the evaporator and turns off based on a signal from the thermostat. This process is absolutely silent when stopped, except for the possible quiet click of the relay.
The duration of operation and downtime varies. In summer, the unit can work longer, taking short breaks. In winter, when the apartment is cool, the idle cycles increase. Normal shutdown always happens smoothly: the motor quiets down and there is silence. If you hear gurgling or fluid pouring after stopping the engine, this is normal, this is how the refrigerant moves in the system.
Particular attention should be paid to models with the system No Frost. In them, the compressor shutdown may be accompanied by the sounds of fans or a defrost timer. Users often get scared, thinking that the equipment is broken when they hear clicking or buzzing noises even when the motor is turned off. In fact, this is the automatic defrosting of the evaporator.
- ✅ The compressor stops smoothly, without sharp blows or knocks.
- ✅ The pause between starts is from 10 to 40 minutes, depending on the load.
- ✅ There is no smell of burning or overheating insulation near the back wall.
- ✅ The temperature in the chambers is stable and corresponds to the set values.
⚠️ Attention: The design and operating algorithms may vary slightly depending on the year of manufacture and the specific series of the refrigerator. Check the information with the technical documentation of your model Indesit to clarify operating standards.
Planned shutdown: preparing for washing or moving
When it comes to how you should To turn off the refrigerator Indesit at the owner’s request, it is important to follow a strict sequence of actions. Simply unplugging the cord is a blunder that could result in oil getting into the refrigerant circuit or damage to the compressor the next time you start it up. The correct procedure begins long before the circuit physically breaks.
The first step is always defrosting. Even if you have a model with No Frost, before long-term downtime or transportation, you must completely defrost the unit. To do this, turn the thermostat control to position 0 or Off, remove all products and open the doors. Leave the equipment alone for at least 10-12 hours, preferably a day, so that all the ice turns into water and evaporates.
After defrosting and washing, if you are planning transportation, it is extremely important to follow the vertical position rule. The compressor is suspended on springs, and if it shakes, it can damage the tubes. If transportation is possible only lying down, then after installation in a new place do not turn it on the refrigerator is at least 4-6 hours (or better 24 hours) so that the oil flows back into the engine crankcase.
☑️ Checklist before turning off
If the refrigerator is simply put away for storage (for example, at the dacha in winter), leave the doors ajar. This will prevent mold and musty odors from forming inside the chambers. A hermetically sealed, empty refrigerator is an ideal environment for the growth of bacteria and fungi, the smell of which is then very difficult to remove.
Emergency shutdown: when the equipment is silent or buzzing
Situations when the refrigerator Indesit turns off by itself and does not turn on, or vice versa - buzzes without stopping, require immediate attention reactions. In the first case, we are dealing with a protection or breakdown, in the second, with a freon leak or a thermostat malfunction. Understanding the reasons will help you avoid costly repairs.
A common reason for silence is a tripped compressor thermal protection relay. If the motor overheats, the relay opens the circuit. After a while, when the temperature drops, it should click and try to start the engine again. If you hear a series of clicks, but there is no start, or the engine hums for a couple of seconds and stalls, the problem is more serious. This could be a jammed compressor or a failure of the start relay.
Another scenario: the refrigerator runs continuously without turning off. This often indicates that temperature sensor does not record the achievement of the desired degree. The cause may be a refrigerant (freon) leak. The compressor is trying to bring in the cold, but due to a lack of gas this is impossible. As a result, the motor wears out and can burn out if it is not turned off manually.
| Symptom | Probable cause | User actions |
|---|---|---|
| Silence, light yes | Malfunction of the thermostat or relay | Knock on the thermostat, call a technician |
| Buzzes for 5 seconds and clicks | The compressor is jammed or the starter is burned out | Disconnect from the network, do not turn on until repaired |
| Works without stopping | Freon leakage or wear of the seal | Check the tightness of the door |
| Frequent on/off | Incorrect installation or dirty condenser | Move away from the wall, clean the grille at the back |
Why can’t you turn the refrigerator on and off often?
Frequent switching cycles (less than 5-10 minutes of downtime) prevent oil from returning to the compressor crankcase and create water hammer This leads to rapid wear of the valves and piston group, which ultimately disables the expensive unit.
Typical errors in manual power control
Refrigerator owners Indesit often make mistakes when trying to “save” equipment or save energy. One of the most common is unplugging the refrigerator from the outlet immediately after it has turned itself off. You can't do this. The system maintains high pressure, and restarting should occur only after the pressure has been equalized, for which the automation is responsible.
Another mistake is the use of extension cords and low-quality surge protectors. A refrigerator is a powerful consumer with a large starting load. A cheap extension cord can cause a voltage drop, due to which the motor will not be able to start the first time, it will hum and get hot. Direct connection into a separate outlet is the only right solution.
Some users try to regulate the temperature by frequently switching the thermostat from minimum to maximum. In mechanical models, this leads to rapid wear of the regulator contacts. In electronic ones - to desynchronization of sensor readings. Set the mode 2-3 (or Eco) and do not touch it unless absolutely necessary.
- 🚫 Do not turn off the refrigerator from the network if there is food left inside (risk of defrosting and bacteria).
- 🚫 Do not use Euro-socket adapters without grounding.
- 🚫 Do not set the regulator to maximum in the heat (the compressor will not turn off and will burn).
- 🚫 Do not ignore the repeated clicks of the relay when trying to start.
⚠️ Attention: If you have turned off the refrigerator to defrost, never use a knife, hair dryer or hot water to speed it up thawing ice. Damage to the evaporator will lead to an immediate release of freon and expensive repairs, which are often not economically feasible.
Diagnostics of problems with the thermostat and relay
If your Indesit behaves inadequate, in 60% of cases the problem lies in the thermostat or start relay. The thermostat is the "brains" that decides when to turn off. If it is faulty, the contacts may oxidize and not open, or, conversely, not close. You can check the mechanical thermostat by closing its contacts directly: if the refrigerator is working, change the regulator.
Start relay - a small block on the side of the compressor. This is what makes the clicking noise when starting up. If the relay is faulty, the compressor will hum, trying to start, but there will not be enough inertia. Visually, there should be no cracks or traces of burning on the relay. When shaken, a working relay should not make any sounds (if it dangles inside, it is broken).
The electronic control board has its own “diseases”. Power surges in the network can damage the compressor control triac. In this case, the refrigerator may turn on and off randomly, or errors will appear on the display (if there is one). Independent repair of electronic modules without circuitry is not recommended - there is a high risk of permanently “killing” the board.
Rules for storing a switched off unit
If you decide not to use the refrigerator Indesit for a long time, for example, you leave it in an unheated house for the winter, you need to know a few nuances. Firstly, most modern refrigerants and oils are designed to operate at above-zero temperatures. In cold weather, the oil thickens, and starting the compressor without preheating is guaranteed to lead to its failure.
Secondly, humidity. In an unheated room, moisture may condense on the inner walls, which will lead to metal corrosion and damage to seals. Therefore, ideal storage conditions are a dry room with a temperature of +5 to +25 degrees Celsius. If this is not possible, dry the unit thoroughly and leave the doors open.
Transportation after storage also requires caution. Even if the refrigerator was standing upright, before turning it on after bringing it into a warm room, let it stand for 3-4 hours. This is necessary so that condensation on the electrical contacts (if it has formed) evaporates, and the temperature of all components becomes equal to room temperature.
Frequently asked questions (FAQ)
How long should the compressor cool down before turning it on again?
Optimal idle time before turning it on again switching on after a normal shutdown is 10-15 minutes. This time is necessary to equalize the pressure in the system and return the oil. If you unplugged the refrigerator from the outlet manually, wait at least 5-10 minutes before turning it back on.
Why does the Indesit refrigerator click loudly when turned off?
A loud click when turned off is usually produced by the thermostat, opening the contacts. The sound can also come from thermal expansion and contraction of plastic parts of the housing or evaporator tubes. If the click is accompanied by a hum and an attempt to start, the problem is in the start relay.
Is it possible to turn off the refrigerator at night to save money?
It is strictly not recommended. Frequent cycles of defrosting and freezing food spoil their structure and taste. In addition, constantly turning the compressor on and off reduces its service life. The energy consumption of a modern refrigerator class A+ or A++ is small, the savings will not justify the risk of breakdown.
What to do if the refrigerator has not turned off for a day?
First, check the tightness of the door and the integrity of the seal. Make sure you don't set it to Super Freeze. If technical reasons are excluded, and the engine continues to run, there is probably a freon leak or the thermostat is stuck. A call to a technician is required for diagnostics.
Is it dangerous if the refrigerator turns itself off and does not turn on again?
This could be a protective reaction to overheating or a power surge. Let the equipment stand turned off for 2-3 hours. If after plugging in the light comes on, but the motor is silent or hums and clicks, the start relay, thermostat or the compressor itself has broken down. Operation in this condition is impossible.
