How to repair a freezer

It is impossible to prepare for breakdowns of household appliances - it fails at the most inopportune moment. Especially discouraging the hostess that moment when the freezer is not working. After all, all the products stored in it, for example, meat, fish or ice cream, can deteriorate. Fortunately, repairing the freezer in many cases is possible to do it yourself with some knowledge and tools.

Major Freezer Malfunctions

The reason for the appearance of faults in the freezer can be both very simple and banal, and quite serious, which cannot be solved without the help of a specialist.From the owners of this home appliances, you can hear the following complaints:

• the freezer does not work;
• the freezer has stopped freezing;
• the freezer does not turn off;
• the device turns on and immediately turns off.

Let us consider in more detail each situation, and what to do.

Freezer not working

In the case when the unit for freezing does not turn on, you should not immediately draw hasty conclusions and think that it has broken. The first thing you should pay attention to the health of the plug, electrical cable and the outlet itself. It is possible that the wires from the terminals have been disconnected in the socket or plug, or there has been a break in the conductors of the cable, and this has caused the freezer to not work. Check out line voltageIf it is lowered, the device will not turn on.

Also, for example, in the freezer of the brand Stinol 106 is sometimes observed timer jammingwhen the “defrost” mode is set. In this case, the unit is not included. But if you turn the ratchet a few degrees, the device starts working. The defect with the timer is explained by the fact that the gears are jammed in the clockwork mechanism. In the Stinol 106 q model, this problem with the timer is also present.

In addition, the camera still may not work for the following reasons:

• the mechanism that controls the temperature regime has failed;
• compressor failed;
• connectors are oxidized.

Of all the above factors that can cause the freezer to fail to turn on, you can do just a repair of the socket, plug or power cord with your own hands.

To check the outlet, plug in any other electrical appliance. If he earned, then look for the reason in the plug. If the plug is OK, ring the cable with a tester. Also, if when the device is connected to the network, the light does not come on inside it, then this indicates cable damage. To check the mains voltage, use a multimeter. A voltage of 220 V is required to start the machine.

The freezer has stopped freezing

If you notice that the freezer does not freeze, and in it the temperature began to rise, should check the following:

• whether the door is firmly attached (a common reason for the unit to freeze badly);
• in what position is the thermostat;
• Is the defrost button on?

So, you checked all the points, but the result did not change,and the freezer still does not freeze. In this case, this fault may cause:

• blockage in the cooling system;
• refrigerant (freon) leakage;
• heater breakage (only in devices with the No Frost function, for example, in the Indesit Noo Frost freezer, Stinol 106 q or Indesit SFR 167 NF);
• breakdown of the thermostat or control unit.

The freezer does not turn off

If you suspect that the freezer is not turned off, it is recommended to watch the device for some time. Normally, it should work in the “one to two” mode, for example, 10 minutes running - resting for 20 minutes. Also, the time may increase if the capacity of the unit is half empty, or the temperature in the room is very high. But, when your observations confirmed that the device does not even think of turning off, or the camera turned off after a long period of time, pay attention to the following points.

1. The best option for the temperature inside the freezer tank is considered to be indicators from -18 to -19 ° C. When set to higher values, the unit will operate without interruption. Therefore, even if the room is hot, you should not expose the temperature too low on the thermostat.It will be easier for the device to maintain the microclimate in the chamber at a standard level than to achieve excessive figures. Also, make sure that refrigeration equipment does not stand close to heating appliances.
2. Possibly installed super freeze mode". Old models do not automatically turn off after turning on this mode. Self-shutdown is available only to modern units.
3. Worn seals on the door. Over time, during prolonged use of the freezer, the rubber seal on the door may crack, deform, delaminate or rub. As a result, the door does not fit snugly, the internal capacity of the apparatus is not sufficiently cooled, because of the constant leakage of cold, the compressor runs non-stop and wears out quickly. Atlas freezer will not leave you a chance to miss the wear of the gasket. If you see that the red light is on, it means that the temperature in the chamber rises (possibly due to the poor fit of the door). If the green light came on, then the temperature returned to normal. If a seal is worn out and the fact that the unit is not freezing hard, try to replace the rubber gasket as soon as possible.How to restore the seal on its own, this is explained video.

The unit turns on and immediately turns off

This behavior of the apparatus is often encountered when compressor breakdown. The motor turns on and immediately turns off, or when started, makes strange sounds. The compressor may fail due to the wear of components, for example, if the unit is operating at maximum cooling at high ambient temperatures. Unfortunately, the compressor can not be repaired. To repair the freezer, you need a complete replacement of the motor-compressor.

For example, replacing the last in the freezing equipment Indesit SFR 167 NF will cost you at least 2500 rubles.

Thus, even though the freezer does not differ in the complexity of the design, for carrying out a high-quality repair of the main components, special and expensive equipment (vacuum pump, gauge manifold, etc.) will be required. Therefore, trying to fix the freezer on its own in case of serious problems is not worth it. This fact is explained by the fact that because of ignorance of some nuances you can make it so that the repair of the unit after your intervention will cost you much more.

When to call the wizard

Without shutting down, the device can work even if there are malfunctions in its various modules.

1. Faulty control module. Due to this defect, there is no signal to shut off the compressor motor. You can fix the situation by replacing the card or by flashing it.
2. There is a blockage in the system. (usually due to thickened engine oil). If this is the case, the compressor is not capable of driving the refrigerant through the line. To eliminate the blockage will have to clean the system well, after which you need to refill with freon.
3. Evaporator sensor malfunction or thermostat broken. If these elements break down, the control unit does not receive a signal about the temperature reached in the chamber and therefore cannot turn off the compressor. If the thermostat breaks down, for example, in the Indesit SFR freezer, it will “freeze” very much, despite your attempts to set the desired temperature.
4. Refrigerant leaked. This is one of the reasons why the unit does not freeze, and this is often due to mechanical damage to the main pipes, for example, if you tried to knock off the ice, during defrosting, with something sharp.In case of freon leakage, cooling will stop, and the compressor will continue to work without stopping, since the temperature sensor will not provide information to the control board that the set temperature has been reached. All that you can do in this situation is to de-energize the equipment, free the capacity of the unit from the products and call the wizard.
