The situation when food turns to stone in the freezer compartment, but it’s warm in the refrigerator compartment is a classic breakdown scenario that owners face equipment Indesit, LG, Atlant and other brands. Such asymmetry of temperature conditions immediately indicates that the compressor is most likely alive, but the circulation of the refrigerant or the cold distribution system is disrupted. Instead of panicking, it is necessary to carry out an initial diagnosis to understand the scale of the disaster: whether you need to call a technician or the problem can be solved yourself.
In most cases, the cause lies in one of three systems: a refrigerant leak, a clogged capillary tube, or a malfunction of the defrost system (in No Frost models). Understanding the operating principle of your unit will help you find source of the faultfaster. If you notice that the back wall in the refrigerator compartment is warm or at room temperature, although it should be cold, this is a sure sign of a heat transfer problem. Next, we will analyze each scenario in detail so that you can accurately determine the breakdown.
It is important to understand that ignoring the problem in the early stages can lead to damage to products and more expensive repairs in the future. A compressor running idle or in emergency mode can overheat and burn out. Therefore, having discovered that the refrigerator has stopped cooling when the freezer is working, act consistently, excluding simple reasons such as incorrect temperature setting before disassembling the equipment.
Fault symptoms and primary diagnosis
The first step There should always be a visual and tactile check. Pay attention to the behavior of the compressor: whether it runs continuously or switches off at short intervals. If the motor hums constantly and gets very hot, but there is no cold in the main chamber, this may indicate freon leakage or thermostat malfunction. In normal mode, the compressor should turn on and off cyclically, maintaining the set parameters.
Check the temperature by touch. In a working refrigerator, the back wall of the main chamber should be uniformly cold, often with frost (in drip systems). If you see that:
- ❄️ The freezer is working perfectly, the food is frozen.
- 🌡️ In the refrigerator compartment the temperature is above +10°C, the food is spoiling.
- 🔇 The compressor works without interruption or, conversely, is silent.
- 💧 It’s dry inside, there is no condensation or, on the contrary, there is water.
These signs help with a high degree of probability to predict the type of breakdown. For example, if the compressor is hot but does not start, the thermal protection relay may have tripped. If it is cold and silent, the problem may be in the electronics or the start relay. In models with the system No Frost it is also worth checking whether air flows from the fan into the main chamber.
⚠️ Attention: If you smell burning or see sparking in the compressor area, immediately unplug the device. Further diagnostics without the skills of an electrician can be life-threatening.
A multimeter is often required for accurate diagnostics, but primary conclusions can be drawn without it. Remember that cooling uniformity is a key indicator of the health of the system. If there is cold only at the back wall or only at the top/bottom, this narrows the search to problems with air or refrigerant circulation.
Refrigerant leak: how to detect and what to do
The most common reason why freon stops doing its job - this is a violation of the tightness of the circuit. The refrigerant circulates through a closed system, and if a hole has formed somewhere (microcrack, corrosion), the gas escapes. As a result, the pressure in the system becomes insufficient for the freon to reach the evaporator of the refrigeration chamber, although in the freezer, where the circuit begins, cold is still generated.
A leak can occur in several places: in the foamed part of the housing (internal circuit), in the heat exchanger on the rear wall (if it is external) or in the places where the tubes are soldered. Often, owners themselves damage the circuit when trying to defrost the refrigerator with a knife or sharp object. In this case freon leak occurs instantly, and the system stops working completely or partially.
Signs of a leak include:
- 📉 Complete absence of cold in one of the chambers when the compressor is running.
- 🔥 Strong heating of the compressor due to idle operation.
- 🛢️ The appearance of oily spots near the refrigerator (freon carries away the oil).
- 🔇 Change in the sound of the motor (may become quieter or more intermittent).
It is difficult to find the leak on your own, since freon is colorless and odorless. Craftsmen use leak detectors or the nitrogen pressure test method. If a leak in the internal circuit (foamed part) is confirmed, repairs may not be economically feasible, since it requires opening the housing and installing an external evaporator.
Is it possible to fill a refrigerator with freon yourself?
Self-refueling is impossible without special equipment (vacuum pump, scales, pressure gauge station). In addition, you cannot simply “add” gas - the system is sealed. First you need to find and eliminate the leak, evacuate the system, and only then charge a strictly regulated amount of refrigerant. Violation of the technology will lead to breakdown of the compressor.
Clogged capillary tube: symptoms and solution
The capillary tube is a narrow channel through which liquid refrigerant is supplied to the evaporator. Its diameter is extremely small, so it is sensitive to contamination. If moisture gets into the system, it freezes in the form of an ice plug, blocking the flow of freon. Also, a blockage can form due to oil oxidation products or dirt remaining after poor-quality previous repairs.
When the capillary tube is clogged, an interesting picture is observed: the compressor works, trying to pump gas, but there is no circulation. The freezer can freeze due to residual cold or running on the last steam, but the refrigerator is completely warm. A characteristic sign is that the condenser grille (rear) only partially heats up or remains cold.
Main signs of a blockage:
- 🧊 The compressor works constantly, trying to gain temperature.
- 🌡️ The condenser (rear grille) is cold or warm only at the outlet of the compressor.
- 🔇 Periodic clicks or gurgling sounds in the tubes.
- ❄️ The evaporator in the freezer is covered with frost unevenly or only at the entrance.
To remove the blockage, the technician needs to depressurize the system, blow the tubes with nitrogen under high pressure and replace the filter drier. The filter drier must be replaced whenever the circuit is opened, as it absorbs moisture and dirt. An attempt to simply “blow out” the system without replacing the filter and vacuuming will lead to re-clogging in a short time.
Problems with the system defrosting in No Frost refrigerators
In units with a system No Frost cold is supplied to the main chamber by air. The fan drives cold air from the freezer through special channels. If you hear that the fan is running, but the air is not coming out or is barely warm, the problem may lie in the defrost system. A snow “coat” freezes on the evaporator in the freezer (often hidden behind a plastic panel) and blocks the air supply channels.
Causes for the formation of an ice plug in the channels:
- Malfunction Defrost heating element (heating element).
- Failure defrost timer or electronic control module.
- Failure defrost sensor (thermostat), which does not give a command to turn on the heating.
- The drainage hole is clogged, due to which the water does not drain and freezes.
As a result, the evaporator becomes overgrown with ice, the fan cannot blow air through this mass, and cold stops flowing into the refrigerator compartment. The freezer continues to freeze, since the evaporator is located there, but its efficiency also decreases over time. The compressor may work without stopping, trying to compensate for the lack of cold.
For diagnostics in models Indesit or Stinol often you have to remove the back panel of the freezer. If you see a block of ice on the evaporator, the defrost system is not working. Checking the heating element and sensors is carried out with a multimeter for an open circuit. Replacing these elements usually does not require complex equipment other than access to the components.
⚠️ Attention: When defrosting ice in the No Frost system, it is strictly forbidden to use a hot air dryer or sharp objects. The plastic of the air ducts is fragile and easily melts or cracks, which will lead to cold leakage into the housing.
Malfunctions of the compressor and start relay
Although the question is about the situation when the freezer is working, problems with the very “heart” of the refrigerator cannot be ruled out. If the compressor is faulty, it may not develop enough power to pump freon throughout the entire circuit, but create residual pressure in the first chamber (freezer). Most often, the culprit is turn-to-turn short circuit windings or wear of the valve group.
The starting relay also often fails. This is a small unit that fits onto the side of the compressor. If its contacts burn out or the coil burns out, the compressor either does not start at all, or it hums for several seconds and clicks, turning off. In some cases, the relay may “stick”, allowing the motor to work, but intermittently.
Symptoms of problems with the motor:
- 🔊 Loud hum, knocking or clanging during operation.
- ⚡ Frequent clicks (attempts to start) and shutdown.
- 🔥 The compressor becomes hot to the point where it is impossible to touch it.
- 📉 No cold even after long-term operation.
If the compressor requires replacement, this is a complex and expensive repair. It includes unsoldering the tubes, installing a new motor, replacing the filter drier, evacuation and refilling with freon. In older models, it is sometimes possible to replace only the starting relay, which is inexpensive and can be done quickly.
Comparative table of malfunctions
To make it easier for you to navigate the variety of symptoms, we have compiled a summary table. It will help you understand where to look first, based on the behavior of your refrigerator.
| Symptom | Probable cause | Difficulty of repair | Required equipment |
|---|---|---|---|
| The compressor is working constantly, no cold | Freon leak or capillary blockage | High | Vacuumator, freon, leak detector |
| The freezer is freezing, the refrigerator is warm, fan noise | Malfunction of the defrost system (No Frost) | Medium | Multimeter, set of screwdrivers |
| The compressor is hot, clicks and turns off | Faulty start relay or compressor | Medium/High | Multimeter, new relay |
| There is cold only at the back wall | Incorrect loading or damper malfunction | Low | No (manual adjustment) |
| There is water in the refrigerator compartment, ice in the freezer | Drain hole clogged | Low | Syringe, warm water, brush |
The table shows that problems are divided into those that can be solved independently (cleaning the drainage, checking settings) and those that require the intervention of a professional (working with freon, replacing the compressor). Diagnostics —this is 50% of the success of the repair, so do not skip the analysis stage symptoms.
What you can do yourself and what you can trust to a professional
If you find that the refrigerator is not freezing, do not rush to call service. There are a number of actions that you can and should do yourself. This will help save time and money if the problem is trivial. However, it is important to clearly understand the limits of your capabilities so as not to aggravate the situation.
On your own you can:
- 🧹 Completely defrost the refrigerator (at least 24 hours) to remove ice jams.
- 🔌 Check the integrity of the power cord and sockets.
- 🌡️ Make sure that the temperature regulator is not set to minimum.
- 🚪 Check the tightness of the door and the integrity of the seal.
☑️ Checklist before calling a technician
However, if we are talking about refilling with freon, replacing the compressor or complex electronics, it is better to contact specialists. These works require a license, special tools and knowledge. An attempt to do this with your own hands without experience often ends in the final breakdown of the unit.
⚠️ Attention: Prices for repairs and availability of spare parts may change. Before starting work, check the current prices at official service centers or with trusted private craftsmen, since the cost of a compressor can be up to 50% of the price of a new refrigerator.
Prevention and proper care of equipment
So that the situation when the freezer is working, but the refrigerator is notdoes not take you by surprise, it is important to observe operating rules. Regular defrosting (even for the No Frost system once every year and a half) extends the life of the compressor and maintains the efficiency of heat transfer. Do not put hot foods in the chamber and do not overload the refrigerator; leave room for air circulation.
Keep the condenser grill at the back clean. Dust and pet hair act as a heat insulator, causing the engine to wear out. Wipe the door seals and check them for elasticity. If the rubber becomes rough or cracked, the cold will escape and the compressor will break.
Following these simple rules will allow your equipment Bosch, Samsung or any other brand to serve for many years without expensive repairs. Remember that prevention is always cheaper than restoration.
Why did the refrigerator stop freezing after defrosting?
If after defrosting the cold did not appear, you may have damaged the system when chipping ice (pierced the tube), or moisture got into the system, causing a blockage. The defrost sensor could also have failed because it was “stuck” in the “defrost” position. Let the refrigerator stand off for a day, then turn it on. If there is no cold within 5-6 hours, a technician needs diagnostics.
Is it possible to operate a refrigerator if it does not freeze well?
For a short period of time, it is possible, but not recommended. Food in the refrigerator will begin to deteriorate, breeding bacteria. A compressor operating in emergency mode (without shutting down) may burn out in a few days or weeks. It is better to unload the products and start repairing.
How long should a new refrigerator reach its temperature?
After the first turn on or long-term transportation, the refrigerator requires from 2 to 12 hours to reach operating temperature. At this time, do not fill it completely with food and do not open the door frequently. If after 12 hours the freezer does not freeze, and there is heat in the main chamber, this is a defect or breakdown.
Does the temperature in the room affect the operation of the refrigerator?
Yes, it does. If the room is too cold (below +10°C), the oil in the compressor thickens and it may not start. If it is too hot (above +35°C), the refrigerator will work at its maximum capacity, which can lead to overheating and insufficient cooling of the main chamber.
