The situation when the freezer in the refrigerator suddenly stops working Indesitcan take you by surprise, especially if large stocks of food are stored in it. Owners of equipment often face the fact that the temperature inside rises above normal, the ice melts, and food begins to spoil. This does not always mean that the unit has completely failed and requires an expensive replacement.
In most cases, the problem lies in specific components that can be diagnosed. Indicators of the control panel may flash, signaling a loss of cold, or the refrigerator may be quieter than usual. Understanding the operating principles of refrigerant and compressor will help you quickly determine the scale of the disaster.
In this article we will examine in detail, why Indesit it stopped freezing, what symptoms indicate a freon leak, and which indicate problems with the electronics. We will consider both simple operating errors and complex technical malfunctions that require the intervention of a technician.
Primary diagnostics: external signs and simple checks
Before calling a technician or disassembling the unit, it is necessary to conduct a visual inspection. Often the reason that freezer does not hold the cold is trivial. Make sure that the refrigerator is not placed close to the wall and that the ventilation gap is not blocked. Overheating condenser may cause the cooling system to stop.
Check the seal tightness doors. If the rubber seal is dirty, cracked, or simply does not fit tightly, warm air constantly enters the chamber. The compressor will work hard, trying to compensate for the heat flow, but will not reach the desired temperature.
Pay attention to the operation of the compressor. If it hums continuously, but there is no cold, or is completely silent, these are two different failure scenarios. In the first case, there may be a leak, in the second - problems with the starting relay or electronics.
Refrigerant leak: symptoms and finding the location of damage
One of the most common reasons why it does not freeze Indesitis a banal freon leak. The refrigerant circulates in a closed circuit, and if the seal is broken, the gas escapes and cooling stops. This often happens in models with a foamed evaporator, where corrosion can corrode the tubes from the inside.
You can determine a leak by characteristic signs. You may notice bulges or, conversely, dents on the back wall of the refrigerator. If you hear hissing during operation or see oily spots under the unit, this is a sure sign of depressurization of the system. Freon itself has no odor, but it circulates along with the compressor oil.
It is important to understand that it is impossible to refill the refrigerator yourself. Special equipment is required to evacuate the system and accurately dose the gas. Attempts to simply “add” freon without looking for a leak will lead to repeated breakdown in a short time.
⚠️ Attention: If you find traces of oil on the tubes or compressor housing, under no circumstances plug the refrigerator back into the network until the fault is eliminated. Operating a compressor without sufficient oil and refrigerant can cause it to seize up.
What types of freon are used in Indesit?
In modern Indesit models, the environmentally friendly refrigerant R600a (isobutane) is most often used. It is flammable, so system repair work requires special care and professionalism. Older models could be fueled with R134a. The exact type of gas is indicated on the nameplate, usually located inside the refrigerator compartment or on the back wall.
Faults of the compressor and start relay
The compressor is the heart of the refrigerator. If it fails, the refrigerant cannot circulate. However, often it is not the motor itself that is to blame, but start relay a device that helps the engine start. If the relay is burned out, the compressor will try to start, make a clicking sound and immediately stall.
Symptoms of a compressor malfunction include intense heating of the motor housing (it may be so hot that it is impossible to touch it) and the absence of vibration characteristic of a running unit. In some cases, the motor may hum, but not start the piston group.
Replacing the start relay is a procedure accessible to a home mechanic with basic skills. You need to remove the casing at the back, disconnect the wires and replace the part with a similar one. If the problem is in the compressor itself (an interturn short circuit or a wedge), it will need to be replaced, which is a complex and expensive procedure.
☑️ Diagnostics of the compressor unit
Problems with the No Frost defrost system
In models Indesit with the system No Frost a frequent cause of loss of cold is a malfunction of the defrost system. Ice builds up on the evaporator, blocks the air circulation channels, and cold stops flowing into the chamber. Outwardly, it may look like the refrigerator is working, but not freezing.
Key elements of the system that fail:
- ❄️ The defrost heating element —a heating element that melts the ice. If it burns out, the ice does not melt.
- ❄️ Defrost sensor is a thermistor that tells the control unit when the heating needs to be turned on. If it “lies”, defrosting will not start.
- ❄️ Defrost timer (or electronic module) - controls the operating cycles. A failure in its operation results in a constant cooling mode without pauses for defrosting.
You can diagnose the problem by manually defrosting the refrigerator for 24 hours. If after turning it on it works normally, but after 1-2 weeks the problem returns, then the defrost system is not functioning. In this case, replacement of faulty elements is required.
Failures in the operation of the electronic control module
Modern refrigerators Indesit are controlled electronically. Control module (board) receives signals from temperature sensors and controls operation of the compressor and fans. Voltage surges in the network, moisture or manufacturing defects can lead to the burning of board components.
Signs of electronics failure:
- 🔌 The indicators on the panel flash randomly or light up all at once.
- 🔌 The compressor does not respond to commands or turns on for a few seconds and turns off.
- 🔌 The temperature in the chambers does not correspond to the set values, although the system is working properly.
Repairing the module requires knowledge in radio engineering. It is often cheaper and more reliable to replace the entire board than to look for a burnt capacitor or relay. However, before replacing, be sure to check the power circuit and sensors, as they could cause the module to fail.
| Symptom | Probable cause | Difficulty of repair |
|---|---|---|
| Ice on the back wall, no cold | System malfunction No Frost | Medium |
| Compressor is silent, no light | Problem with wiring or socket | Low |
| Humming, clicking, does not start | Start relay or compressor | Medium/High |
| Works constantly, little cold | Freon leakage or wear compressor | High |
Replacing the seal and adjusting the doors
The tightness of the door is a critical parameter. If seal lost elasticity, becomes deformed or dirty, the tightness is broken. Warm air penetrates inside, moisture condenses and turns into an ice coat, blocking the operation of the unit.
You can check the seal using a sheet of paper. Clamp the sheet with the door around the perimeter. If it pulls out too easily without resistance, then the seal is broken in that area. Also inspect the rubber for cracks and tears.
Often the problem is solved by simply washing the seal with warm water and soap. If the rubber becomes hard, you can try warming it with a hairdryer or treating it with silicone grease. As a last resort, you will need to replace the seal with a new one, selecting it according to the model Indesit.
⚠️ Attention: When installing a new seal, do not stretch it too much. The corners of the profile may not straighten out immediately - you can carefully warm them with a hairdryer or use inserts (for example, rolled paper) in the corners until the rubber is completely straightened.
When you need to call a professional technician
There are a number of situations when self-repair is not only useless, but also dangerous. If you have diagnosed a freon leak, you will need to solder the tubes, evacuate the system and refill with gas. This is work for professionals with a license and equipment.
Also, a master is needed if:
- 🛠️ The compressor needs to be replaced (soldering and oil injection is required).
- 🛠️ The capillary system is clogged (requires purging with nitrogen under pressure).
- 🛠️ The electronic control module burned out, and simply replacing the fuses did not help.
Attempts to eliminate these faults using homemade methods often lead to the fact that the refrigerator has to be thrown away. Professional repairs will extend the life of your equipment Indesit for many years.
Why does the Indesit refrigerator freeze but does not turn off?
This is a classic sign of a freon leak or loss of compressor performance. The unit tries to reach the set temperature, but due to a lack of refrigerant or low pressure, it cannot do this. The thermostat constantly gives the command to work, and the motor works without rest.
Is it possible to use a refrigerator if it does not freeze?
For a short time - yes, if you defrost it for repair. Continued operation in this mode (especially with a freon leak) will lead to the compressor burning out. If the reason is a faulty thermostat, food may spoil due to defrosting or, conversely, freeze.
How long should the refrigerator cool down after defrosting?
After complete defrosting (minimum 24 hours), the refrigerator requires 2 to 6 hours to reach operating temperature. If after 6-8 hours of operation at maximum power the freezer does not start to freeze, then the problem is technical, and not in long-term defrosting.
What to do if ice freezes in the Indesit freezer on only one side?
This may indicate a local blockage in the circulation system or a malfunction of the fan (in No Frost systems), which Distributes cold air unevenly. It is also worth checking the tightness of the door on the side where there is less or more ice.
How often do you need to defrost a No Frost refrigerator?
The No Frost system does not require regular defrosting to remove ice, as it does it automatically. However, at least once a year, it is recommended to completely turn off the refrigerator, wash it and let it rest to remove odors and check the operation of the mechanisms.
