Buying new household appliances is always a joyful event, which, however, can be overshadowed by an unpleasant surprise. You brought the unit home, unpacked it, turned it on, but after a few hours you discover that it is still warm inside and the food is not cooling. The situation when the new refrigerator does not freezecauses panic and a lot of questions about defects or breakdowns.
Before getting upset and calling the service center, you need to carry out the initial diagnostics yourself. In most cases, the reason lies not in a technical malfunction of the compressor, but in violation of operating rules or operating features of the system No Frost and drip defrosting. Understanding the physical processes occurring inside the chamber will help you save time and nerves.
In this article we will analyze in detail all possible scenarios: from a banal error with transportation to complex defects in the refrigerant circulation system. You will learn how long you need to wait for the temperature to set, how to check the thermostat and why the position of the case affects cooling.
Violation of the rules of transportation and rest
One of the most common reasons why a newly purchased refrigerator has stopped freezing or has not started doing so at all is ignoring the rules of transportation. When transported horizontally, compressor oil may leak into the refrigerant circuit. If you turn on the equipment immediately after installation, the compressor will run “idle” or overload, trying to pump the hydraulic plug.
The settling time directly depends on the ambient temperature and the position in which the equipment was transported. In winter, especially in cold weather, the oil becomes thick and takes longer to drain back into the crankcase. Ignoring this step often results in the user seeing a running fan and a burning light bulb, but the refrigerator compartment is not cooling.
⚠️ Attention: If you turned on the refrigerator immediately after horizontal transportation, immediately unplug it. Allow the equipment to stand in an upright position for at least 12-24 hours before restarting.
It is also important to consider that even vertical transportation with strong shaking could cause oil displacement. Modern compressors are sensitive to the level of lubrication, and its lack in the working area leads to a lack of pressure in the system.
Insufficient time to set the temperature
Many users mistakenly believe that cooling should begin instantly after the thermostat clicks. In fact, a new refrigerator needs time to stabilize its operating processes and achieve the specified temperature conditions. This is especially true for models with a large volume of cameras or function Total No Frost.
The average first start time can range from 2 to 12 hours. During this period, the compressor works continuously, trying to cool the entire internal volume and chamber walls. If you loaded the refrigerator with food immediately after turning it on, the process will take even longer, since the heat capacity of the food is high.
It is important to distinguish between the operation of the compressor and the actual cooling. The engine may hum, giving the impression of active operation, but the refrigerant circulation has not yet reached its full potential. Do not open the doors during the first hours of operation, so as not to disturb the heat exchange.
Improper installation and ventilation
The operating efficiency of the refrigeration unit directly depends on the conditions of its installation. If the condenser (the black grill on the back or sides) is unable to release heat to the environment, the cooling system will no longer function correctly. The compressor will work non-stop, trying to compensate for overheating, but cold will not appear inside.
A common mistake is to install the refrigerator close to the wall or in a kitchen niche without maintaining any gaps. Instructions for any model Bosch, LG or Indesit requires free space for air circulation. Overheating of the compressor can lead to its automatic shutdown by the thermal relay.
The installation level is also critical. If the refrigerator is not level, the doors may not fit tightly, or the oil in the compressor may not be distributed evenly. Check the adjusting feet and use a building level for diagnosis.
| Parameter | Normal | Consequences of violation |
|---|---|---|
| Gap at the wall | Minimum 5-7 cm | Overheating of the condenser, cooling failure |
| Corruption of the housing | No more than 2 degrees | Loose fit of the door, loss of freon |
| Temperature in the room | From +10 to +32 °C | Thermostat malfunction, freezing or overheating |
Errors in setting the temperature mode
Modern refrigerators are equipped with complex electronic control systems, and the user can accidentally set the wrong parameters. If the refrigerator compartment is warm, check to see if the "Holiday" or "Eco" mode is activated, which are designed to save energy and can increase the temperature inside.
On models with electronic control thermostat may be knocked down during transportation or power surges. Try performing a factory reset. Sometimes it is enough to simply reset the temperature to a lower one and wait for the result.
Pay attention to the distribution of air flows. If you block the vents inside the chamber with food, cold air will not be able to circulate. In systems No Frost this leads to local overheating, although the evaporator can work properly.
Hidden settings in the menu
In some models (for example, Samsung or LG) there is a service menu or demonstration mode, which is activated by a combination of buttons. In this mode, the refrigerator lights up, but does not freeze. Check the instructions on how to exit demo mode (usually holding the Freeze and Cool buttons for a long time).
Problems with seals and tightness
Even a new refrigerator may have a manufacturing defect in the sealing rubber on the doors. If the door does not fit tightly, warm air from the room constantly enters. The compressor does not have time to compensate for the heat flow, and the temperature inside rises.
You can check the tightness with a simple test with a sheet of paper. Clamp the sheet between the door and the body around the perimeter. If the sheet is pulled out without resistance, then there is a gap in that place. Also visually inspect the rubber for folds, creases or dirt that could have gotten there during unpacking.
Often the problem is solved by simply adjusting the door hinges or cleaning the seal from factory grease. However, if the rubber is deformed, the part will need to be replaced under warranty.
⚠️ Attention: Do not use a hair dryer to “straighten” the seal on a new refrigerator. This can damage the structure of the rubber and deprive you of warranty service.
Technical malfunctions and manufacturing defects
If all of the above reasons are excluded, and the refrigerator still does not freeze, there is a high probability of a technical malfunction. Unfortunately, manufacturing defects occur even among famous brands. The main problems are related to refrigerant leakage or compressor malfunction.
Freon leakage often occurs in places where pipes are soldered or due to microcracks in the evaporator. The symptom may be a quiet hiss when turned on or, conversely, complete silence if the protection has been triggered. In this case, professional repairs are required, including finding leaks and refilling the system.
It is also possible that the compressor start relay or the motor itself may fail. If you hear a click, a hum lasts a few seconds, followed by silence and a second click, the compressor cannot start.
☑️ Diagnostics before calling a technician
When it is necessary to call a technician
Independent repair of complex refrigeration equipment is prohibited and dangerous. If you suspect a gas leak or electronic failure, you must contact an authorized service center. It is especially important to do this if the refrigerator is new and under warranty.
The technician will conduct diagnostics using pressure gauges and leak detectors. He will be able to determine exactly why the refrigerator has stopped freezingand will fix the problem using original spare parts. Attempts at independent intervention can lead to permanent damage to the unit.
Remember that keeping the receipt and warranty card is your right to free service. Do not hesitate to demand that defects be corrected if the equipment does not meet the stated characteristics.
How long does it take for a new refrigerator to reach temperature?
Usually the primary cooling process takes from 4 to 12 hours. The time depends on the volume of the chambers, the ambient temperature in the room and the load of products. Complete stabilization of the mode can take up to 24 hours.
Why is the refrigerator humming, but not freezing?
This may indicate that the fan in the No Frost system is working when the compressor is faulty, or that the compressor is working, but there is no freon in the system (leakage) or it is clogged. It is also possible for the piston group to jam.
Is it possible to turn on the refrigerator in cold weather?
It is strictly not recommended to turn on the refrigerator if it was brought in from the cold without first warming the room for 3-4 hours. Condensation on the control board and frozen oil in the compressor can damage the equipment.
What to do if it is warm in the refrigerator compartment and ice in the freezer?
This situation often occurs when the damper that regulates the supply of cold air is faulty, or when the air ducts are frozen. This may also be a sign of a freon leak when the compressor power is only enough for the freezer.
