Why the Indesit refrigerator does not cool: a complete guide to faults

The situation when you open the door of your favorite refrigerator Indesitand warmth greets you inside can take you by surprise at any moment. Product spoilage occurs quickly, and you need to act decisively, but without panic. Often, owners immediately call service, although in half of the cases the problem can be diagnosed independently, saving time and money.

Refrigeration equipment of this brand is famous for its reliability, but even time-tested models Indesit C138G or more modern versions have failures. The lack of cold when the compressor is running in 80% of cases indicates a refrigerant leak or blockage of the capillary system, which requires the intervention of a wizard. However, before sounding the alarm, it is worth excluding trivial reasons related to operation.

In this article we will analyze all possible scenarios, from simple configuration errors to complex technical breakdowns. You will learn to understand the signals your unit gives and make informed decisions about further repairs. A careful study of the symptoms will help you more accurately describe the problem to a specialist or, perhaps, fix it yourself.

Checking the basic settings and operating conditions

Before looking for a breakdown inside the mechanism, make sure that the equipment is installed correctly and is configured correctly. Sometimes the reason is trivial: the refrigerator Indesit might simply overheat or the operating mode has gone wrong. Check whether the unit is standing close to a wall or radiator, as heat transfer disturbance often leads to a stop in cooling.

Pay attention to the position of the temperature regulator. On mechanically controlled models, the slider may have accidentally moved to the “0” or “Min” position. In electronic versions, check whether the mode Super Freeze or “Vacation” is activated, which can change the logic of the compressor.

⚠️ Attention: If you have just defrosted the refrigerator and turned it on, do not expect cold instantly. System units No Frost and drip models require from 2 to 12 hours to reach operating mode.

It is also worth checking the tightness of the seal to the body. If the rubber band is dirty or deformed, cold air will escape and the compressor will not be able to cope with the heat flow. Simple cleaning or replacing the seal often solves the problem.

Diagnostics of the operation of the compressor and start relay

The “heart” of the refrigerator is the motor-compressor. It is he who drives freon through the system. If you hear that the engine is humming, but there is no cold, or it turns on for a couple of seconds and clicks when it turns off, these are alarming symptoms. Start relay it could fail, preventing the engine from starting fully.

In some cases, the compressor works constantly, without turning off, trying to gain temperature. This may indicate that there is not enough cold due to a leak, or it does not give the command to stop. Long-term operation in this mode is dangerous due to overheating of the windings. thermostat malfunction, which does not give a stop command. Long-term operation in this mode is dangerous due to overheating of the windings.

If the compressor is silent and does not make any sounds, the problem may be in the electrical circuit. Check if there is voltage at the outlet, if the plug and wire are intact. The internal wiring of refrigerators Indesit is reliable, but power surges could damage the electronics or relays.

Problems with the refrigerant and capillary system

One ​​of the most common reasons why a two-chamber refrigerator does not cool Indesitis a freon leak. The refrigerant circulates in a closed circuit, and if a microcrack has formed somewhere (often in the foamed part of the housing or in the evaporator), the gas gradually evaporates. Without freon, heat is not removed.

The second option is clogged capillary tube. An ice or mud jam could form in the system, blocking the movement of matter. In this case, the compressor may hum, trying to push freon, but circulation does not occur. It is impossible to eliminate such malfunctions on your own.

Diagnosing a leak visually is difficult, since freon is odorless and colorless. However, if you see swelling of the back wall inside the chamber or oily spots under the refrigerator, these are sure signs of depressurization of the system.

Symptom Probable cause Necessary actions
The compressor runs constantly Freon leak Call a technician, search for leaks, refuel
The compressor clicks and stalls Faulty start relay Replace the relay (you can yourself)
It’s cold only at the back wall Clogged or poor circulation Purge the system, replace the filter drier
Noisy operation, vibration Wear compressor Motor diagnostics, possible replacement

Malfunctions of the defrost system (No Frost)

If you have a model with the system No Frostand it has stopped cooling, while a layer of ice or ice is visible on the back wall of the freezer “fur coat”, the problem lies in the defrost system. The evaporator is overgrown with ice, and air cannot circulate through it to the chambers.

Several elements are responsible for the defrosting process: Defrost heating element, a defrost sensor and a timer (or electronic module). If the heating element burns out, the ice does not melt. If the sensor is stuck, the control module “thinks” that defrosting is in progress and does not turn on the heating. As a result, the evaporator turns into an ice monolith.

You can check the heating element with a multimeter for resistance. If the chain rings, the element is intact. If not, replacement is required. It is also worth checking the drainage hole: if it is clogged with debris or ice, the water does not leave from melting, but freezes below, blocking the operation of the system.

☑️ Diagnostics of the No Frost system

Done: 0 / 4
⚠️ Attention: When defrosting the evaporator with a knife or sharp objects, damage the tubes. Use only a hair dryer or hot water. Damage to the evaporator in the No Frost system leads to expensive repairs.

Malfunctions of the thermostat and electronics

The thermostat (thermostat) is a sensor that tells the compressor when to turn on and when to turn off. If it is faulty, the refrigerator may not “know” that it is warm inside and not start the cooling cycle. In models with electronic control, the control module is responsible for this. Symptoms of thermostat failure: the compressor does not turn on at all, or it turns on rarely and works for a very short time. On electronic models, the display may show errors or flashing temperature indicators. Resetting the settings ( Indesit with electronic control is responsible for this control module.

Symptoms of a broken thermostat: the compressor does not turn on at all, or turns on rarely and works for a very short time. On electronic models, the display may show errors or flashing temperature indicators. Reset settings (Reset) sometimes helps if a software failure has occurred.

Replacing a mechanical thermostat is a relatively simple procedure. You need to remove the regulator handle, unscrew the nut and replace the sensor, observing the temperature regime of the new element. Electronic modules require professional re-soldering or board replacement.

How to check a thermostat with a multimeter?

Remove the thermostat and immerse its sensitive part (capillary) in cold water with ice. Call your contacts. If the resistance does not change or the circuit does not close/open when the temperature changes, the part is faulty.

When you need to call a professional technician

Despite the desire to save money, there are situations when self-repair of the refrigerator Indesit is dangerous or impractical. If the diagnosis indicates a freon leak, special equipment is required: a vacuum pump, a pressure gauge station, scales for precise filling and a set of soldering tools.

Also, you should not climb inside the foamed contour without experience. An attempt to find and solder a leak in the foamed part of the case often leads to the fact that the refrigerator completely stops working. Professionals use thermal imagers and leak detectors to pinpoint the location of damage.

If you do not have electrical skills and do not know how to use a multimeter, it is better not to take risks. Incorrect replacement of a compressor or heating element can lead to a short circuit or fire.

Frequently asked questions (FAQ)

Why the Indesit refrigerator works, but does not freeze top chamber?

This is a common problem for dual-chamber models. Most likely, the cold air supply channel from the freezer to the refrigerator compartment is clogged or the damper (if there is one) is faulty. Also, the reason may be freezing of the evaporator in the No Frost system.

How long should a new Indesit refrigerator cool down after transportation?

If the refrigerator was transported vertically, 2-3 hours is enough. If in a horizontal position, wait at least 12 hours for the oil to drain into the compressor. Loading with food is possible only after full operation (about a day).

Is it possible to replace the compressor on an Indesit refrigerator yourself?

Theoretically, it is possible if you have the skills to solder copper tubes and vacuum the system. However, without professional equipment it is difficult to achieve the required vacuum level, which will lead to rapid breakdown of the new compressor due to moisture in the system.

What to do if ice freezes on the back wall in the Indesit refrigerator?

A small layer of ice in the drip system is the norm; it should drain during defrosting. If there is a lot of ice (“a fur coat”), check the tightness of the door closure, the condition of the seal and the operation of the thermostat. The defrost cycle may be broken.
