The situation when the refrigerator Indesit stops freezing always takes you by surprise. You open the door, and there is warm air, food begins to spoil, and panic grips the household. This is a common problem faced by owners of equipment of different years of manufacture, from old models with a freezer at the bottom to modern two-chamber units.
Before calling a technician or looking for a new equipment, it is worth conducting an initial diagnosis. Often the reason lies in trivial things that can be eliminated on your own in a few minutes. However, if the problem is refrigerant leak or a compressor breakdown, you cannot do without professional intervention. Let's look at all possible scenarios.
It is important to understand that the algorithm of actions depends on exactly how the unit behaves. Is the light on? Is the engine humming? Is there frost on the back wall? Answers to these questions will help narrow down the troubleshooting and save time.
Quick check: do not rush to look for a breakdown
The first thing to do if your Indesit stopped cooling is to check the basic settings and operating conditions. Sometimes the problem is solved without a screwdriver and a pressure gauge. Make sure the appliance is level and the door closes tightly. If the seal is worn out or ice has frozen, the seal is broken and the cold goes away.
Pay attention to the operating mode. Perhaps you accidentally switched the refrigerator to Super Freeze or, conversely, set the minimum power. It is also worth checking that the ventilation holes inside the chamber are not clogged with food. Air circulation is a key factor for the correct operation of the system No Frost or drip defrosting.
⚠️ Attention: If you notice that the refrigerator runs continuously without turning off, but does not freeze, this is a signal of a serious problem with the circulation system or thermoregulation. Do not ignore this symptom.
☑️ Primary diagnosis
Here is a list of actions that need to be performed first:
- 🔌 Check whether the plug is plugged into the outlet and whether there is voltage in the network.
- ❄️ Make sure that the thermostat is not on minimum or in the "0" position.
- 🚪 Inspect the door seal for damage and dirt.
- 🧊 Check to see if an “ice coat” has formed on the evaporator.
Malfunctions of the thermostat and temperature sensors
One of the most common reasons why Indesit it does not freeze is the failure of the thermostat (thermostat). This element is responsible for turning the compressor on and off depending on the temperature inside the chamber. If it is “stuck” or its sensitive element has lost its seal, the compressor may simply not start.
In models with electronic control, air sensors are also responsible for temperature control. If one of them transmits incorrect data to the control module, the refrigerator may “think” that it is already cold inside and not turn on the cooling. Diagnostics of such elements requires a multimeter and knowledge of the circuit of your model. defrost sensors and air sensors. If one of them transmits incorrect data to the control module, the refrigerator may “think” that it is already cold inside and not turn on the cooling. Diagnostics of such elements requires a multimeter and knowledge of the circuit of your model.
How to check a thermostat with a multimeter?
To check a mechanical thermostat, remove it and immerse the capillary tube in cold water with ice. Ring the contacts: they should close. If there is no resistance, the part is faulty.
Symptoms of a broken thermostat or sensors:
- 🔇 The compressor is silent, although the chamber is warm.
- 🌡️ The temperature in the chamber does not correspond to the set value.
- 💡 The light is on, but the motor does not start even after defrosting.
Replacing the thermostat in mechanical models is a relatively simple procedure. However, in modern Indesit systems Full No Frost replacing the air sensor may require partial disassembly of the internal lining.
Problems with the compressor and start relay
The heart of any refrigerator is the compressor. If Indesit it hums, but does not freeze, or a click is heard and the motor immediately stops, the problem may be in the start-up relay. This device starts the motor and protects it from overloads. Relays often fail due to voltage surges or natural wear.
A more serious situation is turn-to-turn short circuit the compressor windings or its full wedge. In this case, the engine may hum, heat up, but not start. Sometimes replacing the relay helps, but if the problem is in the compressor itself, it will need to be replaced, which is an expensive repair.
| Symptom | Probable cause | Difficulty of repair |
|---|---|---|
| Silence, no hum | Thermostat or module is faulty | Low |
| Click and silence | Start relay burnt out | Low |
| Humming for 5-10 seconds and shutting down | Compressor wedge or breakdown of windings | High |
| Works constantly, does not freeze | Freon leak or blockage | Average |
Freon leakage and clogged capillary system
If the compressor is working properly, hums evenly, but there is no cold, most likely there is a failure in the refrigerant circulation system. Freon leakage is a common problem, especially in models where the evaporator is sealed into the housing (crying wall). Metal corrosion or mechanical damage when defrosting with a knife can lead to microcracks.
Another reason is clogged capillary tube. An ice or oil blockage may have formed in the system, which is preventing gas from circulating. Visually, this often manifests itself as follows: the compressor is hot, the condenser (grid at the back) is only partially warm or cold, and the refrigerator and freezer compartments are warm.
⚠️ Attention: Self-filling the refrigerator with freon is impossible without special equipment (vacuum pump, pressure gauge station). Trying to simply “add gas” without eliminating the leak and evacuating the system will only harm the compressor.
Signs of problems with the refrigerant:
- 📉 The condenser at the back is cold or warm only at the beginning.
- 🔊 The compressor works without interruptions.
- 💨 There is no frost in the freezer, the food is defrosting.
Faults in the No Frost system
In refrigerators Indesit s system No Frost an evaporator hidden behind a plastic panel in the freezer is responsible for cooling. The cold is pumped by a fan. If you hear that the motor is running, but the cold does not enter the chambers, the fan may be broken or the air exhaust duct is frozen.
A common problem is failure of Defrost heating element or the defrost timer. If the heating element does not turn on, the evaporator becomes covered with ice, the fan stops spinning (it gets jammed with ice), and air circulation stops. As a result, the chambers are warm, and behind the wall there is a block of ice.
Sequence of checking the No Frost system:1. Defrost the refrigerator for at least 24 hours.
2. Check the resistance of the defrost heating element (should be within normal limits).
3. Ring the defrost sensor.
4. Check the operation of the fan.
To diagnose these elements, it is often necessary to remove the back panel in the freezer. Be careful with plastic latches, they are fragile in the cold.
When you need to call a specialist
There are a number of situations when self-repair is not only useless, but also dangerous. If you find bulging in the case wall, traces of oil under the refrigerator, or smell burnt wiring, immediately unplug the appliance. Also, you should not try to solder the tubes yourself without experience and tools.
Professional diagnostics are necessary if you need to replace the compressor, search for micro-leakage of freon using a leak detector, or replace the filter-drier. These works require licensed materials and skills.
⚠️ Attention: Repair prices may vary depending on the region and model of the refrigerator. Before starting work, always check the final cost with the specialist, including the price of spare parts.
Frequently asked questions (FAQ)
Why does the Indesit refrigerator freeze only the upper chamber?
This is a classic sign of a freon leak or a blockage in the system. First of all, the gas leaves the freezer compartment (if it is at the bottom), and cooling remains only in the upper compartment. The problem may also be a malfunction of the damper that regulates the air flow between the chambers.
How long should defrosting last for testing?
For the ice in the system No Frost and the evaporator to completely melt, a minimum of 12-24 hours is required. A short shutdown for an hour will not work, since the ice in hard-to-reach places will not have time to melt.
Is it possible to operate a refrigerator if it does not freeze well?
Long-term operation in this mode is harmful for the compressor, as it wears out, trying to gain temperature. In addition, it is not safe for products where bacteria can grow. It is better to find and eliminate the cause.
Where is the serial number of the Indesit refrigerator?
Usually a sticker with technical data (PNC) and the serial number is located inside the refrigerator compartment on the side wall or on the base below. The type of refrigerant and the filling volume are also indicated there.
