You brought home a shiny new refrigerator, plugged it in, and it hummed. What's next? Should it work non-stop for the first 24 hours? Why does ice appear on the back wall, and why does the motor turn on and off? These questions plague everyone who encounters new technology. In this article, we will look at which ones signal a manufacturing defect or incorrect installation. which processes in a new refrigerator are the norm, and which ones indicate a manufacturing defect or incorrect installation.
Manufacturers rarely talk about the “hidden” nuances of the first week of operation. For example, that No Frost does not mean a complete absence of ice, and the inverter compressor does not have to operate silently. We have collected current data from service centers LG, Samsung, Atlant and Beko, as well as user reviews for 2023–2026, so that you can clearly distinguish between “grinding in” equipment and a real problem.
First hours of operation: what happens inside?
When you turn it on for the first time refrigerator, it starts self-testing and adaptation cycle. This process can take from 2 to 12 hours depending on the model and ambient temperature. Here's what happens at this stage:
- 🔧 The compressor runs without stopping - it pumps up the cold to quickly reach the set parameters. For models with Linear Cooling (for example, Samsung RB37A52N0SA) this may take up to 24 hours.
- ❄️ Condensation or light frost appears on the back wall - this is normal for systems Direct Cool (drip defrost). In models No Frost moisture should evaporate after 3-4 hours.
- 🔊 Clicks and air flows - the relays are activated, the fans are turned on (in No Frost), the refrigerant circulates. In LG DoorCooling+ you can even hear a slight “whistle” due to the uniform distribution of air.
If your refrigerator is equipped with a display (for example Bosch KAN92VI30R), an indicator may be displayed on it COOLING or INIT —this is not an error, but a signal about the initial setup. This process cannot be ignored: a power interruption in the first 6 hours can disrupt the calibration of temperature sensors.
The noise of a new refrigerator: when is this normal and when is it a defect?
Manufacturers indicate the noise level in the passport (usually 38–45 dB), but these numbers don’t say much. Let's figure out which sounds are acceptable and which require intervention:
| Type of noise | Cause | Normal or problem? |
|---|---|---|
| Low frequency hum | Compressor operation | Normal (if not constant) |
| Clicks when turning on/off | Activation of the starting relay | Normal |
| Gurgling or overflowing of liquid | Refrigerant circulation | Normal (especially in the first day) |
| Whistling or hissing | Fan operation (No Frost) or freon leak | Normal if for a short time. Constant whistling is a problem! |
| Rattling or vibration | Incorrect installation or loose compressor mounts | Problem (feet need to be aligned) |
Particular attention should be paid to inverter compressors (installed in LG InstaView, Samsung Family Hub). They operate almost silently, but can produce a high-frequency squeak (about 16 kHz), which some people hear as a “mosquito sound.” This is not a defect, but a design feature. If the sound is annoying, try moving the refrigerator away from the sleeping areas.
⚠️ Attention: If the refrigerator makes noises metal grinding or knock (as if something is beating inside), immediately unplug it! This could be a fan failure (No Frost) or a loose compressor. Further operation in this mode will lead to serious damage.
Temperature in the chambers: what values are correct?
Many people mistakenly believe that a new refrigerator should immediately reach the set temperature. In fact stabilization can take up to 3 days, especially if:
- 🏠 The room is hot (above 25°C).
- 🚪 The door is often opened (for example, when loading products).
- 🔄 Mode is on
Super CoolorFast Freeze.
Here are the optimal values for different zones (measure with a refrigerator thermometer, not a household thermometer!):
Install the thermometer in the center of the refrigerator compartment for 12 hours|
Check the freezer 24 hours after switching on|
Compare the readings with the model data sheet|
Adjust the settings if the difference is more than 2°C-->
| Zone | Recommended temperature | Permissible fluctuations |
|---|---|---|
| Refrigerator compartment (main compartment) | +3…+5°C | ±1°C |
| Fresh zone (0°C) | –1…+1°C | ±0.5°C |
| Freezer compartment | –18°C (standard) / –24°C (deep frozen) | ±2°C |
| Door shelves | +5...+8°C (warmest place!) | ±1.5°C |
If the temperature in the freezer does not drop below -12°C after 24 hours, check:
- The tightness of the door closure (perhaps the packaging is in the way or the seal is deformed).
- Operating mode (in some models Indesit the default is
Eco Mode, which saves energy, but freezes worse). - Location of products (not overload the chamber - leave gaps for air circulation!).
Condensation and ice: where should they be and where should they not be?
Even in refrigerators No Frost moisture may appear - this is not always a breakdown. Let's figure out where condensation is acceptable and where it requires intervention:
- ❄️ Ice on the back wall of the refrigerator compartment —the norm for models with drip defrosting (Atlant XM 4021-000, Biryusa 101). It should melt during automatic defrosting (every 6–12 hours).
- 💧 Water under fruit crates is a sign of a clogged drainage hole. Clean it with a cotton swab or a special brush (included with some models). data-i="153">Closing tightness of the door (the seal could have been deformed during transportation). Beko).
- 🧊 Ice in the freezer — if its layer exceeds 5 mm, check:
- The tightness of the door closure (the seal may have been deformed during transportation).
- Frequency of opening (warm air enters the chamber each time).
- Mode operation
Super Freeze(in Liebherr CNef 4815 it can work up to 72 hours straight!).
In models with Total No Frost (for example, Gorenje NRK6191MCB) ice should not accumulate at all. If you notice frost on the walls of the freezer after a week of operation, this is a reason to contact a service center - the defrost heater or temperature sensor may be faulty.
⚠️ Attention: If in the refrigerator with No Frost over the first 3 days, ice more than 3 mm thick was formed do not try to chip it off with a knife! This may damage the evaporator. Turn off the refrigerator for 12 hours to completely defrost, then turn it on again. If ice appears again, call a specialist.
Compressor operating cycle: how long should it work, how much should it rest?
One of the most frequently asked questions: “Why does a new refrigerator work? without stopping? The answer depends on the type of compressor and operating conditions.
For conventional (linear) compressors normal cycle:
- Operation: 10–20 minutes.
- Rest: 15–30 minutes.
On the first day, the ratio may shift towards longer work (up to 40 minutes in a row).
For inverter compressors (installed in LG GA-B489YDQZ, Panasonic NR-BN30A1):
- They work almost constantly, but at reduced power.
- Peak loads (loud noise) occur only when first turned on or after loading warm products.
- Average operating factor: 0.8–0.9 (that is, 80–90% of the time the compressor is active, but at 30–50% power).
If your refrigerator is operating more than 1 hour without stopping at normal room temperature, check:
Make sure the door is closed tightly (check the seal)|
Check if the mode is turned on Super Cool or Holiday|
Measure the temperature in the chambers (the sensor may be lying)|
Turn off the refrigerator for 1 hour, then turn it on again-->
Why inverter the compressor may not turn off at all?
Inverter models (for example, Hitachi R-VG460PUC6) are designed for continuous operation with smooth power adjustment. If the refrigerator is new, it can work without pauses for up to 3 days - this is normal! The main thing is that the temperature in the chambers corresponds to the set temperature. If after 72 hours the compressor still does not turn off, but in the freezer. –10°C instead of –18°C, this is a sign of a sensor malfunction or a freon leak.
Smells in a new refrigerator: plastic, chemicals, burning
The first days after purchase, the refrigerator may emit unpleasant odors. Let's figure out which of them are safe and which require action:
- 🧴 The smell of plastic or “new technology” - the norm for the first 3-5 days. Particularly strong in models with antibacterial coating (Sharp SJ-FX560V-SL). To remove it faster, wipe the internal surfaces with a solution of water and lemon juice (1:1).
- 🧪 Chemical smell (acetone, solvent) —may appear. due to residual technological lubricant on the parts. Ventilate the refrigerator for 12 hours with the door open. If the smell does not disappear, contact the store (this may be a faulty seal).
- 🔥 Smell of burning or melted plastic — dangerous signalimmediately unplug the refrigerator. data-i="199">Smell of burning or melted plastic
- Short circuit in the wiring.
- Overheating of the compressor (if the refrigerator is close to the wall).
- Ingress of a foreign object on the heating element (No Frost).
In models with a carbon filter (Midea MRF263SFMB1), a slight “charcoal” smell may be felt - this is normal and goes away after 2-3 days. If the smell is too strong, replace the filter (they are usually included).
⚠️ Attention: If a burning smell appears after 1-2 weeks of operation, this may be sign compressor overheating due to incorrect voltage in the network. Check the socket with a multimeter - the voltage should be 220-230 V with a deviation of no more than 5%.
Energy consumption: how much should “eat” a new refrigerator?
Manufacturers indicate annual electricity consumption (for example, 250–400 kWh/year), but in the first days consumption may be higher. Here's what you need to know:
- ⚡ In the first 24 hours, the refrigerator may consume 2–3 times more usually due to continuous operation. compressor.
- 📊 Average daily consumption after stabilization:
- Class
A+++: 0.5–0.8 kWh/day. - Class
A++: 0.8–1.2 kWh/day. - Class
A+and below: 1.2–1.8 kWh/day.
- Class
- 🔌 Consumption surges can be connected with:
- Activation of modes
Super CoolorFast Freeze. - Frequent opening of the door (each time the compressor is turned on for 5-10 minutes).
- High room temperature (above 25°C).
- Activation of modes
To check the actual consumption, use wattmeter (costs from 500 ₽). If the readings exceed the passport values by more than 30%, check:
- Temperature in the chambers (perhaps the compressor is running idle due to a faulty sensor).
- Door seals (if damaged, the refrigerator loses cold).
- Operating mode (in some models Haier is set by default
Party Mode, which increases consumption by 40%.
Checklist for the first week: what to check.
To make sure that the refrigerator is working correctly, follow these steps in the first 7 days:
Measure the temperature in the refrigerator and freezer compartments|
Listen to the compressor for extraneous noise|
Check the door seals (a sheet of paper should not fall out when the door is closed)|
Evaluate the level of condensation (there should not be any)| No Frost it shouldn't exist)|
Check the electricity consumption after a day of operation|
Make sure that the legs are adjusted (the refrigerator should not swing)-->
If everything is in order, we can assume that the refrigerator has passed the "break-in". If deviations are found, contact the service center during the warranty period (usually 1-2 years) data-i="249">during the warranty period incorrect installation, and not a manufacturing defect.
⚠️ Attention: Warranty service rules may vary depending on the manufacturer and region. For example, LG and Samsung require the preservation of packaging for warranty repairs in the first 14 days. Please check for details. documents or from the seller.
FAQ: Frequently asked questions about the new refrigerator
Why does the new refrigerator get very hot on the sides?
This is normal! Heat is dissipated through the condenser (grid on the back wall or on the sides in models). c Side-by-Side (for example Samsung RS62R5001M9) the side panels can heat up to 40-45°C. The main thing is that the refrigerator is not close to the furniture (a gap of at least 5 cm is needed).
Is it possible to turn on the refrigerator immediately after delivery in winter?
No If the refrigerator! transported at a temperature below +5°C, before turning it on it must stand in a warm room at least 6 hours (for models with a compressor) or 12 hours (for No Frostotherwise the oil in the compressor will thicken and it may fail.
Why does ice form in a refrigerator with No Frost?
The reasons may be different:
- 🚪 Frequent or long opening of the door.
- 🔧 Defrost heater malfunction (requires repair).
- 📦 Overload of the freezer (air circulation is disrupted).
- 🌡️ High humidity in the room (more than 70%).
Try defrost the refrigerator for 12 hours. If ice appears again, call a professional.
How to properly wash a new refrigerator before first use?
Use warm water with a mild detergent (for example, dishwashing liquid). Prohibited:
- Abrasive sponges (scratch the surface).
- Chlorine-containing products (destroy seals).
- Hot water (can deform the plastic).
After washing, wipe the surfaces dry and leave the door open for 1-2 hours for ventilation.
Is it necessary to defrost a new refrigerator with No Frost?
Technically, no, but it is recommended to do a general cleaning once a year.:
- Unplug the refrigerator.
- Remove all products and shelves.
- Rinse the internal surfaces with a solution of baking soda (1 tablespoon per 1 liter of water).
- Wipe the door seals with silicone grease (sold in hardware stores).
- Leave the door open for 3-4 hours for complete drying.
This will help avoid unpleasant odors and extend the life of the equipment.
