Switching on a new or defrosted refrigerator Indesit is a critical stage on which the durability of the unit and the quality of food storage depend. Many owners make the mistake of believing that it is enough to simply plug the plug into the socket and immediately load the shelves, however correct startup requires compliance with a certain algorithm of actions. Ignoring basic rules can lead to increased wear on the compressor or incorrect distribution of refrigerant in the system.
The first thing you will notice after turning on the power is startup compressorwhich may be accompanied by a characteristic hum or gurgle. This is an absolutely normal physical process of freon circulation, which should not cause panic. It is important to understand that getting to operating temperature conditions takes time, and rushing to load products can ruin the equipment.
In this article we will analyze in detail all stages of the refrigerator Indesit in the first hours and days of operation. You will learn which sounds are a sign of serviceability, and when to sound the alarm, and also become familiar with the nuances of the operation of various cooling systems.
⚠️ Attention: If the refrigerator has just been delivered from the store in the winter, it should absolutely not be turned on immediately. Let the equipment stand in an upright position in a warm room for at least 3-4 hours to acclimatize and drain the oil into the compressor.
Initial start-up and entry into mode
Immediately after you have connected the unit to the power supply, electronic module or the mechanical thermostat gives the command to start the engine. In models Indesit with the system No Frost this process can be almost silent in the first seconds until the fan starts. The usual cooling cycle begins with intensive operation of the motor, which must bring the temperature in the chambers to the specified parameters.
The time required for complete cooling directly depends on the volume of the chambers, the ambient temperature in the room and the type of refrigerant. On average, a modern refrigerator comes into operation in 2–4 hours, but final stabilization can take up to a day. During this period, Indesit reaches the regime in 2–4 hours, but final stabilization can take up to a day. During this period compressor can work almost without stopping, which is a normal situation for the initial start-up.
It is not recommended to open the doors too often during the first hours of operation. Every time you open the door, warm, moist air comes in, forcing cooling system to work harder. This increases the time to reach the target temperature and energy consumption.
You should also take into account that during the first cycles of operation, stronger heating of the side walls of the case may be observed. This is due to the fact that condenserlocated inside the walls (in models with a foamed capacitor), actively gives off heat. If the sides are warm or even hot to the touch, this is a sign of proper operation of the heat exchanger, and not a defect.
Sound diagnostics: normal or malfunction
The acoustic background of a working refrigerator Indesit consists of several sources, and it is important to be able to distinguish between them. Uniform humming motor is the main sound that should be barely audible at a distance of 1-2 meters. Modern inverter models operate much quieter than classic ones, creating only light background noise.
However, in addition to humming, you can hear other sounds that often frighten inexperienced users. These include:
- 🔊 Gurgling and overflowing - the sound of movement refrigerant through the system tubes, especially noticeable immediately after the compressor stops.
- 🔊 Crackling and clicking sounds are the result of thermal expansion and compression of the plastic parts of the housing and evaporator when the temperature changes.
- 🔊 Hissing - can occur in systems No Frost during operation of dampers or defrosting.
- 🔊 Vibration - if it is transmitted to the floor, check the adjustment of the support legs.
Particular attention should be paid situations where sounds become loud, intermittent, or metallic. The knock of the piston on the cylinder walls, a loud clanging sound during startup or a prolonged whistle indicate mechanical malfunction. In such cases, it is better to stop operation and call a technician, since further work can lead to complete failure of the unit.
Why does the refrigerator click when turned off?
A click when the engine stops is the sound of the contacts of the starting relay or thermocouple opening. This is a normal process, indicating that the thermostat has recorded the desired temperature and turned off the power to the compressor.
It is important to note that the nature of the sounds may vary depending on the position of the unit. If the refrigerator is not level, the vibration from the operating motor amplified and transmitted to the body, creating a resonating hum. Checking the horizontal installation is the first step in diagnosing excessive noise.
Compressor operation and switching cycles
The heart of any refrigerator Indesit is the compressor, which provides circulation refrigerant. After switching on, it operates in a cyclic mode: a period of work is followed by a period of rest. The duration of these cycles depends on the settings of the thermostat, the amount of food and the temperature in the room.
In normal operation, after reaching the set temperature, compressor should turn off. Uptime and downtime have a roughly 1:2 or 1:3 ratio. That is, if the motor has been running for 10 minutes, it should rest for about 20–30 minutes. Continuous operation without interruptions is permissible only in Super Freeze or during initial loading, but not in normal mode.
Inverter models Indesit are characterized by a different operating logic. They rarely turn off completely, instead inverter motor simply reduce the speed to a minimum, maintaining the temperature. This avoids temperature changes and reduces energy consumption, but creates the feeling that the refrigerator is “always running.”
| Parameter | Normal value | Fault symptom |
|---|---|---|
| Motor operating time | 10–20 minutes | More than 40 minutes without stopping |
| Rest time | 20–40 minutes | Less 5 minutes or no rest |
| Case temperature | Warm (40–50°C) | Very hot or icy |
| Noise level | Up to 40 dB | Loud knocking, clanging, howling |
If you observe a situation when compressor turns on, works for a couple of seconds and turns off with a click, and then tries to start again after a short period of time - this is a so-called “soft start” with protection. This behavior indicates problems with the starting relay, motor windings or power surges in the network.
Features of No Frost and Static cooling systems
Refrigerators Indesit can be equipped with various cooling systems, each of which has its own operating features after switching on. In models with the No Frost system (or Full No Frost), you will hear the fan operating almost immediately after startup. It provides forced circulation of cold air through the chambers, which speeds up the cooling of products.
Main difference No Frost —no ice on the evaporator, which is hidden behind a plastic panel. Once every 8–12 hours (depending on the model), the automation turns on Defrost heating element. At this point, the compressor and fan stop and you may hear a quiet hissing or crackling noise. This melts the accumulated frost, and the water flows into the drainage pan.
☑️ Checking the No Frost system
In models with static system (drip defrosting) cooling occurs due to natural convection. Cold air sinks, so the temperature on different shelves may vary. There is no fan in the main chamber, which makes the unit quieter, but requires manual defrosting of the freezer (if it is not No Frost) and periodic removal of condensation.
It is important to understand the difference in the distribution of air flows. In Indesit s Multi Air Flow air is supplied through several holes, which ensures a more uniform temperature. If you notice that food is freezing in one part of the chamber and warming up in another, the ventilation holes may be closed or the damper is faulty.
Temperature readings and their stabilization
Temperature control is a key aspect of proper operation. After turning on, the refrigerator Indesit should gradually reduce the temperature in the refrigerator compartment to +2...+5°C, and in the freezer to -18°C and below. The process does not occur instantly, and the thermometer may show jumps in the first hours.
For accurate diagnosis, it is recommended to use an external thermometer placed in a glass of water in the center of the chamber. The built-in display (if equipped) may be inaccurate. Stable values should be established after 5–7 hours of operation in an empty refrigerator.
Factors influencing the speed and quality of cooling:
- ❄️ Load density - an empty refrigerator holds the temperature worse than a partially filled one.
- ❄️ Tightness of the seal - transmission warm air disrupts the operating mode thermostat.
- ❄️ Location - proximity to the battery or direct sunlight interferes with heat transfer.
- ❄️ Frequency of door openings - each opening lets in heat and moisture.
⚠️ Attention: Do not immediately set the thermostat to maximum cooling (usually number 5 or 7, or Min mode). This will force compressor to work at the limit, which can lead to overheating and failure at the first start. Start with average values.
If after 10–12 hours of operation the temperature in the chambers does not drop below +10°C, and the compressor operates continuously, this is a signal about system malfunctions. Possible reasons: freon leak, capillary tube clogged, or loss of compressor performance.
Common problems during first start-up
Even new equipment Indesit can exhibit strange behavior, which is often mistaken for breakdown. One of the common problems is the formation of condensation or even puddles under the refrigerator. In most cases, this is not a leak, but the result of high humidity in the room or a clogged drain hole, which is easy to clean.
Another common situation is that the refrigerator does not turn on at all. Before calling a technician, check that there is voltage in the outlet and that the power cord is intact. Sometimes the problem lies in surge protector or an extension cord that cannot withstand the starting current of the compressor. Connect the equipment directly to the outlet.
Also, users often encounter an unpleasant odor after switching on. If the refrigerator is new, it is the smell of plastic and packaging, which disappears in 2-3 days. If the smell is chemical or burning, immediately unplug the device. This may indicate defective wiring or insulation.
Recommendations for operation and care
In order for the refrigerator Indesit to serve for a long time and work efficiently, it is important not only to turn it on correctly, but also to ensure proper care Regular washing of the internal chambers, checking the cleanliness of the condenser grille at the back and monitoring the condition of the seals will prolong the life of the unit. Do not forget that ventilation there should be free space around the housing.
Do not place hot foods in the chamber. This creates an excess load on cooling system and leads to the formation of excess condensation and ice. Allow food to cool to room temperature before placing on shelves.
Periodically check that the refrigerator is not warped. Over time, the legs can become loose, causing vibration. Tighten the adjustment screws to ensure a stable position. Correct installation is the key to quiet operation and no problems with the compressor.
How often do you need to defrost No Frost?
The No Frost system does not require regular defrosting to remove ice, but hygienic washing and complete shutdown for drying are recommended 1-2 times per year.
How long does the Indesit refrigerator take to get cold after the first turn on?
Usually, it takes from 2 to 4 hours for the initial cooling of empty chambers. However, to completely stabilize the temperature and return to normal operation, it is recommended to wait 12–24 hours before fully loading with food.
Why does the Indesit refrigerator hum loudly after turning on?
The hum may be caused by improper installation (touching walls or furniture), uneven floors, or the operation of a particular compressor. If the sound is metallic or accompanied by a knocking sound, this is a sign of a malfunction.
Is it possible to immediately load food into a new refrigerator?
No, it is not possible. First, the refrigerator must run empty for several hours to reach operating temperature conditions. Loading warm food immediately after switching on will cause the compressor to overload.
What to do if the light does not light after switching on?
Check whether the lamp is burnt out and whether the door is tightly closed (in some models the light goes out when closed). If the lamp is new and the door is open but there is no light, the door switch or wiring may be faulty.
Is it normal for the sides of the refrigerator to be hot?
Yes, this is normal. In modern models, the condenser (heat exchanger) is often built into the side walls of the case. During operation, they heat up, releasing heat into the room. This is a sign that the cooling system is working properly.
