The main reasons why the refrigerator works, but does not freeze

Quite often there are situations when the refrigerator works, but does not freeze. In this case, you should not rush to call the master, because perhaps the cause of failure is not as complicated as it may seem.

Today we will review the information on how to diagnose the refrigerator on our own, as well as consider the most common reasons why the refrigerator does not freeze, but the main compartment continues to work.

Instructions for self-diagnosis

Before proceeding with self-diagnostics of the refrigeration unit, you should make sure that it is connected to the network, that it is securely installed and that the doors are tightly closed. If all these conditions are met, then you can proceed to the diagnosis of the equipment, which involves the following actions:

1. Attention should be paid to the “Defrost” button, especially if it is located inside the refrigerator compartment. It often happens that the user himself accidentally presses a button, thereby activating the defrost function.
2. Pay attention to the seals on the doors of the refrigerator. It is not an exception that in the refrigerating chamber these elements simply broke or lost their former flexibility. They are subject to replacing. This is often found in units that have served for more than one year. At the same time, it is necessary to leave the door on the freezer compartment loosely closed, because in this compartment, most likely, there is a layer of ice that prevents the door from closing tightly, due to which the temperature in the main compartment slightly rises.
3. Often the unit does not cool due to a faulty sensor. This can be checked by changing temperature control.
4. You should bring your hand to the motor, which is located in the bottom niche of the equipment. If it is very hot, it is likely that the engine's thermal protection has been activated due to overheating of the refrigerator. It is necessary to disconnect the equipment and move it slightly away from the wall. If after a certain time, when the refrigerator has completely cooled,when turned on, everything began to work properly - the problem was only that the engine did not have time to cool down.
5. It is necessary to measure the voltage on the engine with a tester. If it is missing, then the problem was the failure of the thermostat of the refrigerator.

Thus, with self-diagnosis, it is possible to identify and eliminate common small faults, why the refrigerator works, but at the same time the freezer does not perform the tasks. However, if after these actions the refrigerator still does not freeze, the reasons may be more serious.

Possible malfunctions of the refrigerator

Along with minor possible reasons, you can also identify more complex equipment malfunctions.

If the engine for some time is working properly, while there are heard the sounds of the engine, but after it turns off and there is no cold, then the motor-compressor may not start up. Additionally, you can hear clicks after about 10 seconds. buzz of a motor-compressor - this is how the thermal protection located in the thermal relay is activated. And the motor is trying to make a restart after 3 minutes.

The reasons for this behavior may be several, namely:

• relay failure;
• a starting capacitor was broken;
• burned the motor.

What actions should be taken in such cases? The relay is fixed on the motor-compressor, so you need to inspect the relay and if periodic clicks are detected, it can be concluded that it is working properly. And with the "silence" of this part - you have to replace it.

The capacitor to start the motor can be checked with a tester. For this, it is first necessary to discharge it through resistance. When the capacitor is in good condition, the tester's shooter, installed on the resistance measurement in mOhm, must first drop sharply and then return to the initial position.

If the condenser was intact, but the refrigerator is still not freezing, you will most likely have to contact the workshop to replace the burned-out motor.

Quite often the reason for the failure of the freezer is freon leak from the system. This confirms the long-term operation of the engine and the presence of cold condensate on it. Freon may evaporate due to the formation of a microcrack in the evaporator.This happens often after tearing off any frozen product from the wall along with ice, as well as after strong vibration during prolonged operation of the unit. Another cause of freon leakage can be cracked tubes that go to the evaporator from the compressor, for example, as a result of moving equipment. It is difficult to determine the place of freon leakage on your own, as it is after soldering and gas injection.

If the equipment is not cold, the cause may be clogged capillaries supplying the refrigerant. In these situations, it is also necessary to seek help from a specialist, because without certain equipment, the system cannot be pushed through.

If you have experience with electrical appliances, you can try repair the refrigerator yourself.
