The situation when Indesit refrigerator ceases to perform its basic functions always takes us by surprise, because we are talking about food safety and food safety. If you notice that the chamber has become warmer than usual, the food is thawing, or the temperature difference has disappeared altogether, this is a signal that a failure has occurred in the system. The Italian brand is famous for its reliability, but even the highest quality units require attention and maintenance over time.
Before calling a technician or panicking, you should carry out the initial diagnostics yourself. Often the reason lies not in the breakdown of complex electronics, but in a banal violation of operating rules or reset settings. However, the problem cannot be ignored: if Indesit refrigerator it freezes poorly, this can lead to rapid deterioration of supplies and costly repairs of the compressor.
In this article we will analyze in detail the main reasons for decreased performance, from simple user errors to complex technical malfunctions. You will learn how to determine whether urgent defrosting is needed or whether it is time to look for a service center.
Primary diagnosis and external factors
First of all, it is necessary to exclude external factors, which often simulate a serious breakdown. If Indesit refrigerator suddenly it starts to freeze poorly, check whether its location or operating conditions have changed. The unit should not be placed close to a wall, near a radiator, or in direct sunlight. The disruption of heat exchange leads to the fact that the condenser does not have time to cool down, and the system is overloaded.
Carefully inspect the back wall of the device. If you see a frozen “coat” or, conversely, a complete absence of frost where it should be, this is an important diagnostic sign. Also check the tightness of the door: if the seal is dirty or deformed, warm air constantly enters the chamber.
- 🌡️ Check the temperature regime: the regulator may have been accidentally moved to minimum.
- 🚪 Inspect the rubber seal around the perimeter of the door for cracks and dirt.
- 🔌 Make sure that the power cord is tightly seated in the outlet and the voltage in the network is stable.
It is important to understand that refrigerator compartment the freezer compartment can behave differently with different types of breakdowns. If one compartment is cold and the other is warm, this narrows the scope of troubleshooting. In models with a No Frost system, the lack of cold is often associated with a malfunction of the fan or defrost heater.
Problems with the thermostat and sensors
One of the most common reasons why Indesit refrigerator does not reach the desired temperature is failure thermostat. This element is responsible for turning the compressor on and off depending on the temperature inside the chambers. If the sensor “lies” or is jammed, the compressor may simply not start or, conversely, work without stopping, but not cool.
Modern electronically controlled models use air sensors instead of a mechanical thermostat. Their readings may be distorted due to oxidation of contacts or software failure. If you hear that the motor is humming, but there is no cold, or there is deathly silence, although the food has already flowed, the problem is most likely in the control circuit.
⚠️ Attention: Replacing the thermostat yourself requires skills in working with electricians. Incorrect connection may lead to a short circuit or failure of the new sensor.
To check the mechanical thermostat, it can be temporarily closed by removing it from the circuit. If after this manipulation compressor it starts and gets cold, it means the part requires replacement. In electronic models, diagnostics are carried out with a multimeter by measuring the resistance of the sensor at different temperatures.
Symptoms of a faulty thermostat
The refrigerator turns on rarely and for a short time; It's too warm inside, even though the engine is running; The motor does not turn on at all, although there is voltage in the network; There is no frost on the back wall or it is uneven.
Faults of the compressor and start relay
The heart of any refrigerator is the compressor. If Indesit refrigerator stops freezing and you hear a characteristic click, followed by a hum, and then silence - this is a classic sign of starting problems. Most often, the starting relay is to blame, which provides an impulse to start the engine.
The relay is an inexpensive part that is relatively easy to replace yourself. However, if after replacing the relay the situation does not change, or the compressor hums but does not start, the problem may be more serious. An interturn short circuit of the motor windings or mechanical wear is possible. In such cases motor-compressor requires professional repair or replacement.
- 🔨 Knocking or vibration during startup indicates mechanical problems inside the compressor.
- 🔥 Strong heating of the motor housing (more than 90 degrees) - a sign of overload or short circuit.
- ⚡ Lack of response to connection to the network may indicate a burnt out winding.
It is worth noting that in two-compressor models Indesit failure of one of the motors will lead to a lack of cold in only one chamber. If there is only one compressor, and the cold has disappeared everywhere, then the diagnostics focuses on it and the refrigerant circulation system.
☑️ Compressor diagnostics
Freon leakage and clogged capillary system
The most unpleasant and costly reason why Indesit refrigerator it freezes poorly is a refrigerant (freon) leak or capillary tube clogged. Freon is a working fluid that, circulating through the system, takes away heat. If its amount in the circuit decreases, the cooling efficiency drops until it disappears completely.
Leaks often occur in places where tubes are soldered, in the foamed part of the body (evaporator) or in the door perimeter heating circuit. Signs of a leak are the absence of the characteristic gurgling of liquid during operation, as well as the absence of frost on the evaporator or its presence only at the beginning of the circuit. A clogged capillary tube is manifested by similar symptoms: the compressor works, but there is no gas circulation.
| Symptom | Probable cause | Necessary actions |
|---|---|---|
| The refrigerator hums, but does not freeze | Freon leak | Searching for leaks, evacuation, refilling |
| The engine runs without stopping | Lack of refrigerant | Pressure diagnostics, refilling |
| Frost only at the entrance to the evaporator | Clogged capillary tube | Purge the system or replace the filter |
| Bloating of the rear wall inside | Corrosion of the evaporator | Replacing an evaporator or installing an external one |
⚠️ Attention: Working with refrigerant requires a license and special equipment. Trying to refill with freon on your own is dangerous to health and can lead to an explosion or fire.
To eliminate these malfunctions, you need to call a technician. He will perform nitrogen pressure testing, find the leak, seal it, replace the filter drier and fill the system with the exact amount freonspecified in the model passport.
Failures in the No Frost system
Owners of models with system No Frost often encounter a situation where the refrigerator is humming, the light is on, but there is no cold. In such units, cooling occurs due to the circulation of cold air, which is forced by a fan through an evaporator hidden behind the rear panel. If this cycle is broken, the cold does not enter the chamber.
A common cause is ice freezing on the evaporator due to a malfunction of the defrost system. The defrost heating element, timer or defrost sensor may fail, causing ice to block the fan from operating. The air stops circulating and the temperature in the chamber rises. This can be seen visually if you remove the back plastic panel in the freezer (after defrosting the unit).
- 💨 The fan does not spin: check it for jamming with ice or a broken winding.
- ❄️ Ice coat on the evaporator: defrost heating element is faulty or sensor.
- 🌀 Noisy air flow: a foreign object may have gotten into the air ducts.
When professional repairs are required
Independent repair is possible only if the thermostat, start relay or seal is replaced. However, if Indesit refrigerator stopped freezing due to problems with the tightness of the circuit or electronics, intervention by a specialist is inevitable. Modern units are equipped with complex control boards, the diagnosis of which requires an oscilloscope and knowledge of circuit design.
You should not delay contacting service if you notice that food is deteriorating faster than usual. Long-term operation of the compressor without switching off (in an attempt to catch up with the temperature when freon leaks) leads to its overheating and expensive replacement. The earlier the problem is identified, the cheaper the restoration will be.
ℹ️ Information: The cost of repair may vary depending on the region, refrigerator model and price of components. Always request a preliminary estimate and a guarantee for the work performed.
To summarize, we can say that there are many reasons why the equipment stopped cooling. From simple defrosting to complex circuit repairs. The main thing is to act consistently, checking simple options before diagnosing complex breakdowns.
Frequently asked questions (FAQ)
Why does the Indesit refrigerator work, but does not freeze after defrosting?
If after defrosting the cold does not appear within 2-4 hours, there may be a failure in the electronics or damage compressor during a power surge. An ice plug could also form in the capillary system if defrosting was carried out mechanically (with a knife).
Is it possible to operate a refrigerator if it does not freeze well?
Short-term - yes, but it is dangerous for the food. Long-term operation in this mode is detrimental to the compressor, which wears out. It is better to temporarily move the products to another place and do diagnostics.
How much does it cost to replace a compressor with Indesit?
The price consists of the cost of a new motor and the work of a technician. On average, this is one of the most expensive procedures in repairing household appliances. The exact amount can only be determined after diagnosing a specific model.
What to do if it is warm in the refrigerator compartment and cold in the freezer?
This may indicate a malfunction of the damper that regulates the flow of cold air (in models with one compressor), or problems with the fan. It is also worth checking whether the air supply channel is not clogged with food.
How often do you need to defrost an Indesit refrigerator?
Models with manual defrosting require disconnecting from the network 1-2 times a year. No Frost and Full No Frost systems do not need defrosting, but preventive washing once a year will not hurt them to maintain hygiene.
