You You bought a new refrigerator or just defrosted the old one, plugged it in - and now you’re looking forward to when it finally reaches the desired temperature. But how long will it take? The answer is not as clear-cut as it might seem. The cooling time depends on the model of equipment, the conditions in the room, the load on the chambers, and even on how correctly you prepared the refrigerator for the first start.
In this article we will look at what factors influence the cooling rate, what standards are considered standard for different types of refrigerators (single-chamber, double-chamber, No Frost), and also what to do if the refrigerator does not get cold for too long. You will also learn how to speed up the process and avoid typical mistakes that many make when turning it on for the first time.
Standard standards for cooling a refrigerator after turning it on
The time required for the refrigerator to reach operating mode varies depending on its type and power. For most modern models, the average figures are as follows:
- 🔹 Single-chamber refrigerators (up to 150 l): 2–4 hours until +5°C is reached in the main chamber.
- 🔹 Two-chamber refrigerators (150–300 l): 4–8 hours to cool both chambers to the specified parameters.
- 🔹 Models with No Frost: up to 12 hours due to additional time for stabilization of the ventilation system.
- 🔹 Built-in and premium models (for example, Liebherr, Samsung Family Hub): up to 24 hours due to difficult climatic conditions systems.
It is important to understand that these figures are approximate. Actual time may vary by ±20% depending on external conditions. For example, if the room is +30°C, the refrigerator will take 30–50% longer than at +20°C. The same applies to load: an empty refrigerator will cool faster than a full one.
Factors influencing cooling time
The speed of cold accumulation depends not only on the model, but also on a number of external and internal factors. Let's consider the key ones:
- Room temperature. The hotter the room, the longer the refrigerator will have to operate at maximum power. The optimal range for rapid cooling is +18…+22°C.
- Volume and load of chambers. An empty refrigerator will cool in 2-3 hours, and a fully filled refrigerator will cool down in 10-12 hours. Products, especially warm ones, act as additional “heat accumulators.”
- Type of cooling system:
- 🔸 Drip system (most budget models) - cools longer due to passive thawing.
- 🔸 No Frost - takes time to start the fans and distribute the cold evenly.
- 🔸 Low Frost (y Bosch, Siemens) - occupies an intermediate position.
Critical moment: if the refrigerator does not cooled to +8°C in the main chamber in 24 hours, this is a reason to check its serviceability. In most cases, the delay is due to improper installation or external conditions, but sometimes technical faults are to blame (freon leakage, thermostat failure).
Step-by-step instructions: how to properly turn on the refrigerator for the first time
Many users are surprised why the new refrigerator does not cool for so long, not suspecting that they themselves have violated the rules of the first start-up. Follow these instructions to avoid mistakes:
Install the refrigerator on a flat surface (check with a level)|Rinse all shelves and containers with warm water and baking soda|Dry the internal surfaces (you can use a hair dryer at minimum power)|Connect to a separate outlet (without extension cords)|Set the thermostat to the middle position (usually “3” or “Eco”)|Close the door and do not open it it for 2-3 hours -->
After connecting to the network:
- Wait until the compressor starts working (you will hear a slight hum).
- Do not load food in the first 1-2 hours - let the refrigerator get cold when empty.
- After 4 hours, check the temperature in the main chamber. If it is above +10°C, increase the cooling power by 1-2 notches.
- Fill the freezer compartment only after it reaches -10°C (usually after 6-8 hours).
- 🚫 Turning on the refrigerator immediately after delivery (you need to wait 2–4 hours to stabilize the oil in the compressor).
- 🚫 Loading warm or hot products in the first hours of operation.
- 🚫 Frequently opening the door to check the temperature (this disrupts the mode).
- 🔹 Before defrosting, take out all the food and let it cool in a cool place (for example, in a bowl of cold water).
- 🔹 After washing, wipe the walls with a dry cloth - moisture slows down cooling.
- 🔹 Do not place the refrigerator close to the wall (the minimum clearance is 5 cm) for better ventilation.
- 🔧 The correct connection to the network (the automatic switch on the panel may have worked).
- 🔧 The position of the thermostat (it could have gone astray when washing).
- 🔧 Presence of ice on the evaporator (if defrosting was incomplete).
Mistakes that are often made:
⚠️ Attention: If the refrigerator was transported in a horizontal position (lying down), before turning it on it must be kept upright for at least 12 hours. Otherwise, oil from the compressor may enter the cooling circuit and cause a breakdown.
How long does it take for the refrigerator to cool after defrosting
After defrosting, the refrigerator gains cold faster than when first turned on, but it still takes time. Average indicators:
| Refrigerator type | Cooling time after defrosting | Notes |
|---|---|---|
| Single chamber (up to 150 l) | 1–2 hours | Provided that the door was not opened during defrosting. |
| Two-chamber (150–300 l) | 3–5 hours | The freezer compartment takes longer to cool than the main one. |
| No Frost | 4–6 hours | Fans require time to distribute the cold. |
| Side-by-Side | 6–8 hours | Due to the large volume and separate cooling systems. |
To speed up the process:
If after defrosting the refrigerator does not cool for more than 10 hours, check:
What to do if the refrigerator does not cool after defrosting?
If the refrigerator does not get cold for more than a day, unplug it for 10 minutes, then turn it on again. If this does not help, check:
1. Thermostat: turn the knob to maximum cooling. If the compressor does not start, the thermostat is faulty.
2. Compressor: touch it with your hand. If it is cold and does not vibrate, a breakdown is possible.
3. Freon leak: if the compressor works, but there is no cold, the circuit is probably damaged.
In these cases, a call is required masters.
How to speed up the cooling of a refrigerator: working methods
If you need the refrigerator to cool faster (for example, before loading a large amount of food), use these tips:
- Set the maximum cooling mode for the first 2-3 hours, then return to standard settings. In models Samsung and LG there is a mode for this
Power CoolorFast Freeze. - Use a fan. Point a countertop fan at the open refrigerator door for 10–15 minutes (no longer to avoid overloading the compressor).
- Place cold water bottles inside. 2-3 plastic bottles with ice water or frozen cold accumulators will speed up the process by 20-30%.
- Minimize the heat load:
- 🔸 Do not place the refrigerator next to the stove or radiator.
- 🔸 Do not load warm foods (even at room temperature).
- 🔸 Cover liquids with lids (evaporation increases humidity and slows down cooling).
What NOT to do:
- 🚫 Set the refrigerator to maximum mode for longer 4 hours - this overloads the compressor.
- 🚫 Use a hairdryer or heater to “help” - this can damage the seals.
- 🚫 Load the freezer with food if its temperature is above -5°C.
What to do if the refrigerator does not cool for too long
If more than 24 hours have passed and the refrigerator has not reached the desired temperature, follow the algorithm:
- Check the power supply:
- 🔌 Make sure that the plug is firmly inserted into the socket.
- 🔌 Try connecting another device to the same socket (for example, a lamp).
- 🔌 Check the circuit breaker on the electrical panel - the protective circuit may have tripped switch.
- Inspect the compressor:
- 🔧 It should vibrate slightly and be warm (but not hot!).
- 🔧 If the compressor does not start, the problem may be in the start relay or thermostat.
- Check the door seals:
- 🔍 Close the door and try to insert a sheet of paper between the seal and the body. If it passes easily, the seal is worn out.
- 🔍 Inspect the seal for cracks or deformations.
- 🌡️ Use a separate thermometer (not built-in!).
- 🌡️ If the main chamber is above +10°C after 12 hours, there is a malfunction.
Typical malfunctions and their symptoms:
| Problem | Symptoms | Solution |
|---|---|---|
| The thermostat is faulty | The compressor does not turn on or runs without stopping | Replacing the thermostat (cost - from 1,500 rubles) |
| Freon leakage | The compressor is running, but there is no cold; there are oil stains on the back wall | Search for leaks and refill (from RUB 3,000) |
| Clogged capillary tube | The refrigerator is slightly freezing, the compressor is hot | Cleaning or replacing the tube (from 2500 rubles) |
| Compressor malfunction | Loud humming, the compressor does not start | Repair or replacement (from 5000 rubles) |
⚠️ Attention: If the refrigerator is under warranty, do not try to repair it yourself! Any tampering with the design (for example, attempting to charge freon) will void the warranty. Contact the brand's service center.
Frequently asked questions about refrigerator cooling time
How long should a new refrigerator cool? No Frost?
Models with No Frost cool longer due to the need to start the fans and distribute the cold evenly. On average:
- 🔹 Main chamber: 6–8 hours up to +5°C.
- 🔹 Freezer: 10–12 hours up to –18°C.
If refrigerator Samsung or LG with the function Power Cool, the time can be reduced by 20–30%.
Why is the refrigerator humming but not cooling?
This is a typical sign of one of the problems:
- Freon leak (the compressor is working “idle”)
- Clog in the capillary tube (refrigerant does not circulate).
- Thermostat malfunction (the compressor does not receive a signal to turn off).
Solution: turn off the refrigerator for 1 hour, then turn it on again. If the problem persists, call a specialist.
Is it possible to turn on the refrigerator immediately after transportation?
No! After transportation (especially in a horizontal position), you must wait:
- 🔹 2–4 hours if the refrigerator was transported vertically.
- 🔹 12–24 hours if it was lying on its side (oil from the compressor could get into the circuit).
Ignoring this rule may lead to breakdown compressor.
How to understand that the refrigerator has finally cooled down?
Signs that the refrigerator has reached operating mode:
- 🔹 The compressor begins to work in cycles (turns on and off every 10-20 minutes).
- 🔹 Light frost appears on the walls (in models without No Frost).
- 🔹 The temperature in the main chamber remains stably at +4...+6°C (check with a separate thermometer!).
Do not focus on the sound: modern inverter compressors work almost silently.
How long does it take for a refrigerator Atlant to cool after defrosting?
Refrigerators Atlant (especially models with a drip system) cool relatively quickly:
- 🔹 Single-chamber: 1.5–2 hours.
- 🔹 Double-chamber: 3-4 hours.
If the process is delayed, check:
- Door closure tightness (the seal could be deformed during defrosting).
- Thermostat position (should be on “2” or “3”).
