Equipment owners Indesit often face a situation where the unit continues to hum, the light inside is on, but the food in the main chamber or freezer begins to deteriorate. This is a classic symptom of a broken refrigeration cycle, which can be caused by either a simple electronic failure or a serious refrigerant leak. If you notice that the Indesit refrigerator does not freezethe first thing you need to do is to carry out an initial diagnosis without immediately resorting to calling a technician.
Modern models, such as Indesit DS 320 or older two-chamber systems, have their own design features. In some cases, the problem is solved by defrosting, in others, an expensive compressor needs to be replaced. A critical sign is swelling of the back wall inside the fridge compartment, which indicates failure of the No Frost system. Understanding the operating principle of your device will help save time and money.
Next we will analyze the main reasons for equipment failure from work, methods of self-troubleshooting and situations where professional intervention is indispensable. It is important to act consistently so as not to aggravate the situation.
Primary diagnostics: checking external factors
Before disassembling the unit or looking for faults in the electrical circuit, it is necessary to eliminate basic operating errors. Often users panic ahead of time, not that the equipment is simply overheated or is in the wrong place. Make sure temperature conditions is set correctly and the door fits snugly to the body.
Inspect the rubber seals for dirt or mechanical damage. If the rubber band Indesit lost elasticity or is deformed, cold air will evaporate, causing the compressor to wear out without achieving the desired result. Wipe the seal with a soft cloth and check the tightness.
It is also worth checking the location of the equipment. If refrigerator stands close to the wall or radiators, heat transfer is disrupted. For normal operation, air must circulate behind the rear grille.
- 🔌 Check that the plug is firmly inserted into the socket and that there is voltage in the network.
- 🌡️ Make sure that the temperature regulator is not set to the minimum value.
- 🚪 Inspect the door hinges to see if the door is skewed and whether it closes tightly.
- 💨 Move the equipment away from the wall at least 5-7 cm for ventilation.
If after checking all external factors the problem persists, move on to a more in-depth analysis of the internal systems.
⚠️ Attention: If you smell a strong burning smell or hear loud clicks immediately after turning on, immediately unplug the device. Further operation may lead to a fire.
Malfunctions of the defrost and evaporator system
One of the most common reasons why Indesit refrigerator stopped freezing is the failure of the automatic defrost system. In models with a system No Frost or Frost Free ice periodically forms on the evaporator, which must be melted by a special heating element. If this process is disrupted, the ice blocks the circulation of cold air.
As a result, the compressor works continuously, trying to lower the temperature, but the cold does not enter the chambers. This is often accompanied by complete or partial icing of the rear wall. To diagnose, you need to remove the back panel in the freezer and visually assess the amount of ice.
Several elements in the defrost system may fail: itself Defrost heating element, a defrost sensor or a timer (relay). In modern models Indesit an electronic control module is often responsible for this process. If the heating element burns out, the ice will not melt, and after some time the air channel will be completely blocked.
Restoring the functionality of the defrosting system requires testing the elements with a multimeter. This is a task for those who have basic skills in working with electrical appliances.
- ❄️ Ice completely blocks the ventilation hole between the chambers.
- 🔥 The defrost heating element may burn out due to a power surge or natural wear.
- 📉 Temperature sensor may have “stuck” and does not give a command to turn on the heating.
- 🔄 The fan may stop due to icing of the blades.
If you find a thick layer of ice on the evaporator, try to completely defrost the refrigerator (at least 24 hours with the doors open). If after switching on it works normally, but after a week the problem repeats, a malfunction in the defrosting system is confirmed.
⚠️ Attention: When defrosting, never use a hairdryer, hot water or sharp objects to chip ice. This may damage the evaporator tubes or the plastic case.
Problems with the compressor and start relay
The heart of any refrigerator is compressor. If this unit is faulty, there will be no cooling anywhere. In technology Indesit there are often situations when the engine hums, but does not start, or starts for a few seconds and immediately stalls with a characteristic click. These are classic signs of problems with the start relay or the motor itself.
The start relay is a small plastic block mounted on the side of the compressor. It supplies a starting impulse to the motor windings. Over time, the contacts inside the relay can become burnt or stuck, causing it to fail to start. Replacing this element is an inexpensive procedure and can often be solved with your own hands.
A more serious situation is an interturn short circuit in the compressor windings or its mechanical wear. If motor-compressor the shaft hums, but does not rotate, or its housing becomes red-hot, most likely the entire unit will need to be replaced. It is also worth checking the capacitor (if it is in the circuit), since its swelling can prevent normal starting.
Sequence of checking the relay:1. Disconnect the refrigerator from the network.
2. Remove the casing at the back of the unit.
3. Remove the plastic cover from the compressor.
4. Carefully remove the starting relay from the contacts.
5. Shake the relay - if you hear a knock inside, it is faulty.
The table below shows the main symptoms and their probable causes in the context of the compressor operation:
| Symptom | Probable cause | Complexity repair |
|---|---|---|
| Silence, no hum | No power, thermostat or module burned out | Low |
| Humming and clicking, starting | Faulty starter relay | Low |
| Strong humming, does not start | Compressor jammed or breakdown of windings | High |
| Works for 5 minutes, then turns off | Motor overheating or freon leak | Medium/High |
How to check the compressor with a multimeter?
To check, you need to remove the relay and measure the resistance between the contacts on the compressor. The normal resistance of the working winding is 10-20 Ohms, the starting winding is 20-50 Ohms. Between the housing and the contacts, the resistance must be infinite.
Freon leakage and blockage of the capillary system
If Indesit refrigerator works constantly, the compressor is hot, but there is no cold, and the inside is dry and clean (no ice), there is a high probability of a refrigerant leak. Freon is a substance that circulates through the system, picking up heat. Without a sufficient amount of gas, the cooling cycle is impossible.
Leaks often occur in places where tubes are soldered, in the foamed part of the housing (where the evaporator is located) or through corrosion of the condenser (grids at the back). Finding a leak on your own without special equipment (leak detector) is almost impossible. In addition, simply adding gas is not a solution, since it will escape again through the same hole.
Another common problem is clogged capillary tube. Oil circulates in the system, which over time can thicken or mix with breakdown products, forming a plug. The symptoms are similar to a leak: the compressor works, but there is no cold, and the condenser (rear grille) remains only partially cold or warm.
Repair in such cases requires calling a technician with a vacuum pump, a pressure gauge station and a supply of freon. The system must be vacuumed, leak repaired or purged, and only after that it is refilled with new gas.
- 🔍 Visually, the leak can be seen by oily spots on the tubes at the back.
- 🌡️ If there is a leak, the condenser often remains cold while the engine is running.
- 🔇 The compressor may work without interruption, trying to gain temperature.
- 🧊 A “fur coat” may appear in the freezer only at the entrance of the tubes, while the rest of the space is warm.
Failures in the operation of the electronic control module
Modern refrigerators Indesit equipped with sophisticated electronics. Control module (board) receives signals from temperature sensors and controls the operation of the compressor, fans and heating elements. If the board is "glitchy", it may not send a command to start cooling, even if all actuators are working properly.
A frequent cause of failures is power surges in the network. As a result, the tracks, relays or microcontroller on the board may burn out. Problems can also arise due to oxidation of contacts or moisture ingress. In some models Indesit there is a "disease" - the contacts on the connectors fall off due to vibration.
Diagnostics of the module requires special knowledge and equipment. However, sometimes a simple error reset (reboot) helps. To do this, you need to unplug the refrigerator for 15-20 minutes and then turn it on again. If the problem was a software failure, the system may work.
If after a reboot refrigerator behaves inappropriately again (indicators flash, the compressor does not turn on), most likely, repair or replacement of the control board will be required.
⚠️ Attention: The electronic module is sensitive to static electricity. Do not touch the board with bare hands without grounding, so as not to damage the microcircuits.
☑️ Electronics diagnostics
Mechanical damage and wear of seals
The reason for the lack of cold is not always in the electrics or freon. Sometimes a banal depressurization of the camera is to blame. If sealing rubber the doors Indesit are worn out, cracked or simply dirty, warm air constantly enters the chamber. The compressor does not have time to cool it, and the temperature inside rises.
You can check the tightness using a sheet of paper. Clamp the sheet with the door around the perimeter. If it pulls out easily and without resistance, there is no tight fit in this place. It is also worth inspecting the door itself for distortions. If the door is skewed, it will not close tightly even with a intact rubber band.
Mechanical damage can also occur inside: cracks in the plastic frame, broken guides that prevent the door from closing tightly. In two-chamber models, the condition of the air ducts is important. If the channel through which cold air flows from the freezer to the refrigerator compartment is clogged with food or ice, the upper compartment will be warm.
Regularly checking the condition of the seals and timely replacing or restoring them (for example, using a hair dryer to straighten them) will extend the life of your refrigerator.
- 🧹 Wash the seal regularly soap solution to remove grease and stickiness.
- 🔥 To restore the shape of the rubber band, you can gently warm it with a hairdryer.
- 🚪 Check whether food or dishes interfere with the door closing tightly.
- 📏 Measure the gaps between the door and the body - they should be uniform.
Frequently asked questions (FAQ)
Why does the Indesit refrigerator freeze only in the freezer and in the refrigerator compartment warm?
Most often this indicates a malfunction of the defrost system (the air supply channel is frozen) or a freon leak. It is also possible that the capillary is clogged or the air circulation fan is not working.
How long should a new Indesit refrigerator cool down after turning it on?
Usually, reaching operating temperature takes from 2 to 12 hours, depending on the model and load. If after 12 hours the temperature has not dropped to the set values, you should look for a malfunction.
Is it possible to replace the thermostat in an Indesit refrigerator yourself?
Yes, if you have the skills to work with a tool and a multimeter. The thermostat is a mechanical device, and its replacement does not require evacuation of the system, unlike repairing leaks.
What does the flashing alarm indicator on an Indesit refrigerator mean?
A flashing indicator (usually red) signals that the temperature in the chamber has risen above the permissible limit. This may be a consequence of a recent loading of warm products, prolonged defrosting, or a malfunction.
