Why the new refrigerator does not cool: a complete analysis of the reasons and solutions

You've just installed your shiny new refrigerator, loaded it with groceries, and a few hours later you discover that the compartments are still at room temperature. The situation is unpleasant, but don’t panic: in 80% of cases the problem is solved without calling a technician. In this article we will look at why a new refrigerator does not cool - from banal installation errors to hidden factory defects. all possible reasonswhy a new refrigerator does not cool - from trivial installation errors to hidden factory defects.

It is important to understand: modern refrigerators (especially models with inverter compressors) have complex electronics, which may behave in unobvious ways. For example, some No Frost and inverter compressors) have complex electronics that may behave in non-obvious ways. For example, some Samsung and LG work in a “gentle mode” for the first 24 hours, and Bosch and Beko may not turn on the cooling until the doors are closed tightly. We have collected unique data on the behavior of refrigerators from 10+ brandsso that you can accurately diagnose the problem.

Before calling the service center or returning the equipment to the store, go through our checklist. Perhaps the solution will only take 5 minutes!

1. Check the obvious: 5 errors when turning on for the first time

According to statistics from service centers, 3 out of 10 calls regarding a “non-working” new refrigerator are associated with banal omissions during installation. Here's what you need to check first:

• 🔌 Power: is the refrigerator connected to the outlet without adapters? Make sure that the plug fits tightly in the connector - some models (for example, Liebherr CNes 4865) do not turn on if the contact is unstable.
• ⚡ Voltage: there should be 220–240 Vin the socket. Use a tester or connect another device (such as a hair dryer) to check the voltage. Jumps to 190 V can block the start of the compressor.
• 🚪 Doors: Are they closed tightly? In models with electronically controlled (for example, Samsung RB37J5240SA), the sensor blocks cooling if the door is ajar more than 2 mm.
• ❄️ Mode: perhaps the “Demo mode” is activated (occurs at Indesit, Ariston). In this case, the indicators are on, but there is no cooling.
• ⏳ Time: some refrigerators (for example, Bosch KGN39VW25R) begin to actively cool only after 2–6 hours after the first turn on - this is normal!

If everything on the list is in order, but the refrigerator still does not freeze, proceed to the next section. If you find one of these problems, allow the equipment 12–24 hours to stabilize the temperature after eliminating the error.

2. Factory defects or transportation damage

Unfortunately, about 2–5% of new refrigerators have hidden defects that appear only after connection. Most often this is:

• 🔧 Damaged compressor: if you hear thud or rattlingwhen you turn it on, and after 5–10 minutes the refrigerator turns off - this is a sign of a jammed motor. Typical for models with linear compressors (for example, LG GA-B489YDQZ).
• 🧊 Refrigerant leak: if the circuit tubes are damaged during transportation, gas escapes and cooling stops. Symptom: the compressor runs without stopping, but the temperature does not drop.
• 🔌 Faulty board control: in refrigerators with electronic unit (for example, Samsung RL62AERBCSA) a microcircuit or relay may burn out. Symptom: the display blinks, displays an error (for example, E1 or F5), but the motor does not start.

How to check?

1. Listen to the sounds: a normal compressor makes uniform humming, without clicks or grinding.
2. Touch the condenser (grid on the back wall): if it cold through 30+ minutes work, this is a sign of freon leak.
3. Look at the display: errors E1, F2, H1 usually indicate problems with electronics.

What to do if the refrigerator has a manufacturing defect?

If a defect appears within 14 days from the date of purchase, you have the right to return or exchange the goods according to the law on the protection of consumer rights. After 14 days only warranty repairs. Important: do not open the seals and do not try to repair it yourself - this will void the warranty!

⚠️ Attention: If the refrigerator was purchased on a marketplace (for example, Wildberries or Ozon), the return conditions may vary, check the details in your order account - some sellers require video recording of the defect.

3. Incorrect installation: why the refrigerator “chokes”

Even a perfectly working refrigerator will not cool if the installation conditions are violated. errors critical errors, which allow 90% of users:

Models with No Frost system are especially sensitive to installation (for example, Atlant XM 6025-031). Their evaporator blower fan may be blocked due to overheating, and the refrigerator stops freezing, although the compressor is running.

4. Electronic failures: why the refrigerator froze

Modern refrigerators are essentially computers with a bunch of sensors. And, like any electronics, they can glitchThe display shows. error:

• 📛 The display shows an error:
  • E1, E2 — problems with temperature sensors (typical for Indesit, Ariston).
  • F3, F4 — malfunction of the defrosting system (No Frost).
  • H1 - compressor overheating (occurs when Samsung).
• ⏻ The refrigerator turns on and turns off immediately: power surge protection is triggered. Check the socket with a multimeter.
• 🔄 Cyclic on/off: there may be a firmware failure (relevant for models with Wi-Fi, for example, LG InstaView).

How to “reboot” the refrigerator:

1. Disconnect it from the network at 10–15 minutes (this will reset the cache of the electronic unit).
2. If there is a button Reset (for example, at Bosch Serie 6) - press it holding for 5 seconds.
3. For models with a display: hold Power Cool + Fridge on 8 seconds (instructions for Samsung RB).

5. Problems with the refrigerant: why the compressor works, but does not freeze

If the compressor hums, but the refrigerator does not cool, freon or its circulation system is to blame. Here are possible scenarios: refrigerant. data-i="197">over time (or due to defects), dirt accumulates in the system, which blocks the flow of freon. The compressor runs “idle”. (freon) or its circulation system. Here are possible scenarios:

• 🔄 Clogged capillary tube: Over time (or due to defects), dirt accumulates in the system, which blocks the flow of freon. The compressor runs idle.
• ❄️ Evaporator freezing: if the fan No Frost is broken, the evaporator is covered with ice, and the cold does not flow into the system. camera.
• 💨 Freon leak: if the tubes are damaged, gas comes out and the pressure in the system drops. The compressor may work, but there is no cooling.

How to diagnose:

1. Touch condenser (grid at the back): if it room temperature through 30+ minutes work, this is a leak or blockage.
2. Shine a flashlight into the freezer: if on the back wall thick layer of ice the sensor is broken. defrost heater or sensor.
3. Listen to fan: in models with No Frost it should turn on periodically. If there is silence, the fan does not work.

⚠️ Attention: If you suspect a freon leak, do not turn on the refrigerator repeat without diagnostics! Operating the compressor without refrigerant leads to its overheating and failure.

6. When to call the service: signs of serious damage

If you have tried everything from the previous sections, but the refrigerator still does not cool, it’s time to contact a specialist. Here are red flagsthat indicate a malfunction:

• 🔥 The compressor is heating up 80–90°C: this is a sign of an interturn short circuit or jamming. The motor needs to be replaced.
• ⚡ Sparks or smell. burning: the compressor winding or control board may have burned out. Immediately unplug the refrigerator!
• 💧 Puddles under the refrigerator: if it is not condensation from defrosting, but an oily liquid, freon or oil is leaking from the compressor.
• 📵 The display does not respond to buttons: the control unit has burned out (typical for Samsung i LG with touch panels).

The cost of repair depends on the breakdown:

7. How to speed up the cooling of a new refrigerator

If, after eliminating all the problems, the refrigerator still cools slowly, use these tips:

• ❄️ Activate the “Super Freeze” / “Power Cool” mode: for most models (Bosch, Samsung, LG) there is a forced cooling function. It is activated by a button on the panel or in the menu.
• 🧊 Do not load food tightly: leave gaps 2–3 cm between products for circulation. air.
• 🚪 Minimize opening doors: every time you open, the temperature in the chamber rises by 3–5°C, and the refrigerator needs time to recover.
• 🌡️ Set the optimal temperature: for the refrigerator compartment - +4°C, for the freezer - -18°C. Lower values increase the load on the compressor.

Average time to reach operating mode for new refrigerator:

• Regular models (for example, Atlant, Biryusa): 6–12 hours.
• No Frost (Samsung, LG): 12–24 hours (due to the defrosting cycle).
• Inverter compressors (Panasonic, Hitachi): 24–48 hours (smooth exit to mode).

Frequently asked questions about new refrigerators

❓ Why does a new refrigerator hum, but not is it freezing?

This is a typical symptom clogging of the capillary tube or thermostat malfunction. The compressor is working, but the freon is not circulating. Another possible reason is failure of the control board, which does not give a signal for cooling. Check whether the temperature indicator is on the display. If not, the problem is. electronics.

❓ How long should a new refrigerator come into operation?

Depends on the type models:

• Conventional refrigerators (drip system): 4–8 hours.
• No Frost: 12–24 hours (due to the defrosting cycle).
• Inverter: up to 48 hours (soft start).

If after 24 hours the temperature in the chambers has not dropped to +5°C —this is a reason to contact the service.

❓ Is it possible to turn on a new refrigerator immediately after delivery?

❌ No! After transportation (especially in a horizontal position), you need to wait:

• 2–4 hours — if the refrigerator was transported vertically.
• 6–12 hours —if transported lying down (oil from the compressor could get into the circuit).

Ignoring this rule can lead to water hammer of the compressor and its breakdown.

❓ What to do if the refrigerator does not cool, but the freezer is working?

This is a sign malfunctions. cold distribution systemsPossible reasons:

• Stuck switching valve (in models with one compressor, for example, Indesit BIAA 13).
• Clogged in capillary tube fridge compartment.
• Failure temperature sensor refrigeration compartment.

Solution: call a technician to diagnose circulation system freon.

❓ Why does the new refrigerator turn off 5 minutes after it is turned on?

It works thermal protection of the compressorReasons:

• Too high voltage in the network (more 250 V).
• Overheating motor due to poor ventilation (the gap to the wall is less 5 cm).
• Compressor jammed (needs replacement).

Try connecting the refrigerator through voltage stabilizer and ensure normal ventilation.
