Stinol refrigerator repair: common problems and how to fix them

Typical breakdowns

One of the common problems with the Stinol refrigerator: its power does not turn on. Possible defects include:

1. plug or power cord failure;
2. the compressor winding is broken;
3. the thermostat or start relay does not work;
4. breakage of the timer in the defrost position.

There are times when the refrigerator freezes too much. This is due to:

1. quick freezing button sinking;
2. incorrect adjustment of the thermo knob.

Weak freezing occurs due to:

1. breakage of the temperature regulator;
2. loose fit of the filler and loss of its elasticity;
3. reduction in compressor performance;
4. violation of the integrity of the electrical circuit.

Also a common problem is freezer breakage, because there are times when the freezer refuses to freeze. The reason for this phenomenon is the leakage of freon gas or depressurization of the system. If you notice that heat is accumulating inside the freezer, then most likely there has been a breakdown in the No Frost system. Troubleshooting can only be done with the help of specialists from the service center.

If you notice that moisture accumulates at the bottom of the unit, then the output tube is to blame. Also, the problem may arise due to clogging of this tube with small particles.

The device of the compressor electrical system

The main element of the refrigerator is the heart. It is necessary to organize the circulation of the refrigerant, and in our case, freon, in accordance with the tubes. In addition to the unit itself, the system contains the following elements:

• starting relay;
• a cryostat responsible for a specific temperature level;
• protective relay to prevent motor overheating.

The motor includes a rotor and a starter.The design of the latter is one or two copper coils. Whereas the rotor is more like a chronic steel shaft working in tandem with the piston engine system.

When the unit is turned on, electromagnetic induction is formed in the coils, which serves as a source of torque. Further, the rotor begins to play up due to centrifugal force, and at the same time the piston moves.

In modern models, the engine is located inside the compressor, which minimizes the likelihood of spontaneous refrigerant leakage. Adjustment in its original form is subject to strong vibration. To reduce it, a special metal balabolka on springs is provided.

On new models, the latter are fixed inside the case, while on the old ones they are outside. The first option is more useful and allows you to dampen vibration much more efficiently. But in the event of a suspension breakdown, it is much more difficult to create repairs.

Refrigerator compressor Stinol

The motor will work until the necessary liquidus is established in the chambers, after which the thermostat is connected. It opens the contacts, and the current stops developing activity to the motor. The compressor also stops working. When the temperature rises, the thermostat contacts will still close and the cycle will continue.

In models of the mid-price and budget category, the thermostat often fails. The element has far from the most complex design and makes sense for a penny, so it is much more practical not to repair it, but to buy a zero one.

Weakly freezes refrigerator Stinol

The line of refrigerators Stinol is long. There are single-chamber, combined models, with manual and electronic control. There are single and double compressor cabinets.But most of the products consist of a bottom freezer and a top refrigerated cabinet. Both one and the other camera can not freeze. The reasons are different, but this brand is characterized by problems with the thermostat, automation or motor-compressor.

Long-term flawless operation of the Stinol refrigerator depends on many factors. If the old device has stopped freezing, the reasons are the reasons:

• There are leaks in the refrigeration circuit, the gas escapes, the remaining mass of refrigerant is not enough to provide cooling capacity.
• Obstruction of the capillary tube - it clogged with sediment from the interaction of oil with freon. Perhaps the filter drier is also clogged - the signs are the same.
• The equipment that controls the process has become unusable - sensors, relays, buttons, contacts.
• The compressor has lost performance due to seal failure, wear of rings, piston. The outlet gas pressure is insufficient, the product does not condense completely.
• The rubber seals were worn out, the door hinges sagged - the tightness of the circuit was broken.

Despite the cessation of production of Stinol refrigerators, there are spare parts for all brands of devices in service centers to replace a worn part 1: 1.

What to do if the single-compressor Stinol stopped turning off the motor?

In the event that the Stinol refrigeration equipment, equipped with one compressor, has a problem, as a result of which the motor simply stops turning off, the freezer compartment continues to function correctly, and summer has reigned in the refrigerator compartment or there is a thick snow cover on the rear panel, like this shown in the photo, the most likely reason for this is an insufficient amount of freon.As a rule, freon does not evaporate on its own, which means that there is a leak in the system that needs to be fixed.

In this situation, you must contact a specialized workshop or service center. Thanks to modern technology, leaks can be found and repaired quickly enough. For a good craftsman, this repair usually takes no more than an hour. When the tightness is restored, refrigerant is added to the system and the refrigerator continues to function normally.

What should I do if there is water under the vegetable drawers in the refrigerator compartment?

If at some point you notice that water began to accumulate in the refrigerator compartment of Stinol, under the boxes for fruits and vegetables, this clearly indicates that the drainage system is clogged and needs to be cleaned. In other words, excess moisture simply cannot seep through the "congestion".

To fix this problem, you can invite service center specialists, or clean the drainage system with your own hands. The only condition, in this case, is maximum accuracy. Otherwise, a thin tube can be damaged and then it will definitely not work without additional costs.

To avoid unpleasant consequences, experts recommend watching a special video, with which, it is likely that you will get answers to most of the questions that may arise.

freon leak

Symptoms: the compressor motor runs for too long, almost without pauses, a sharp increase in temperature in the chambers is possible.

One of the most common causes of problems in the operation of the refrigerator chamber is freon leakage: no refrigerant - no cooling.The standard reason is that in trying to speed up the defrost, you helped yourself with a sharp object, and overdid it. Of course, the natural wear of the evaporator tubes is not excluded, which is why cracks appear in them, especially in old refrigerators. It happens, by the way, the reverse situation - an excess of freon, but the consequences are the same. Call the master: he will close the holes and fill the refrigerator with freon to the norm.

The refrigerator does not turn off and constantly works

This is the most common cause of malfunctions in Stinol refrigerators.

If your single compressor appliance won't turn off, look for signs of a problem. You may notice that the freezer compartment freezes normally, and the upper refrigerator compartment does not work.

The cause of the breakdown may be a freon gas leak. This is the refrigerant that is responsible for cooling the air in the compartments. The leak may be in the steel circuit. To fix the problem, it is necessary to detect damage, fix it and refuel the system with freon.

But first of all, you should check:

1. Refrigerator door. How tightly is it closed? The reason for the loose fit could be the hinges, which sagged due to the heavy load of the door. After tightening the hinges, the door will close normally. It is worth checking the rubber seal - over time, the rubber wears out and becomes dirty. You can replace the seal with your own hands.
2. The set temperature in the chamber. If the control is electronic, the temperature is adjusted automatically, and if mechanical, then manually. Check if the thermostat is set to "Super Freeze" mode.
3. ventilation quality. With poor ventilation or installation near radiators, the refrigerator overheats.Trying to compensate for the increase in temperature, the motor runs without stopping.

If after checking everything turned out to be in order, the matter is broken. What happened:

1. The thermistor and thermostat are broken. In this case, the control module does not receive information about the temperature in the chamber, so the compressor does not turn off. The defective sensor must be replaced.
2. blockage of the capillary tube. Due to depressurization, a blood clot has formed in the tube, which prevents the refrigerant from circulating normally. It is advisable to call a specialist who will find the blockage and fix the problem.
3. Malfunction of the motor-compressor. With prolonged use, motor parts wear out, as a result, the compressor does not have enough power to pressurize the tube, so the set temperature is not reached. The motor needs to be replaced.

Don't expect a complete engine failure. Call a specialist for repair, because during continuous operation, the compressor is double loaded.

Why did the refrigerator stop cooling, and the freezer works and buzzes?

Try cleaning the seal area with soapy water. In no case do not use acidic or alkaline components for cleaning, as the rubber may lose its properties, and then in any case it will have to be removed and replaced with a new one. Do not use abrasive cleaners for cleaning. Normal soap solution will do. If this does not help, or the space behind the sealing rubber is clean enough, without visible crumbs and damage, while the rubber fits snugly, the door closes perfectly, you can turn the refrigerator around and assess the condition of the back wall.

Why the refrigerator stopped cooling, and the freezer works and buzzes:

• It is in the area of ​​​​the rear wall that there are often invisible damage that appeared after transportation, transportation of the device. Some of the tubes may be damaged, a slight dent has appeared.
• If you notice that after the delivery of a new device, there are some depressions and dents on the back wall, while the tubes are uneven, do not sign the document on the proper condition of the device and send it back.
• Even if the device is working, over time, specks and dust particles can accumulate in the deformed area, which will lead to blockage of the cooling system. Most likely, it is in this place that the tube will clog, the refrigerator will not perform its functions.

Refrigerator Features

The freezer compartment of the Stinol refrigerator is made of polystyrene. The space between the compartments is filled with polyurethane foam for thermal insulation. The capillary piping is used as a throttling device, which makes the refrigerator sensitive to changes in humidity and air pollution.

All Stinol refrigerators are divided into evaporative and compressor types. They work as follows: the device uses a substance called a refrigerant to cool it - a liquid that evaporates at room temperature.

The refrigerator can have either one or two compressors, depending on the model. The compressor is a steel coil, which is fixed with metal plates. The presence of several compressors allows you to separately adjust the operation of each compartment of the refrigerator.

Refrigerators have two types of evaporators:

1. static, located on the shelves;
2. system "NoFrost", which is located in a special compartment.

An important element for the stable operation of the refrigerator is the electrical system. It consists of the following elements:

1. a thermostat is needed to maintain a given temperature level;
2. thermal protection;
3. electric motor;
4. start relay.

This system has the following principle of operation:

• When voltage is applied, the current moves from the thermostat to the forced defrosting button, then to the thermal protection, then to the starting relay and from it flows to the motor winding. The current supplied to it gives a voltage higher than necessary, this is because the starting relay operates and closes the contacts only at this voltage level.
• After that, the relay transfers current to the starting winding, and the motor starts to rotate. The motor is running, the refrigerator starts to freeze. When the temperature reaches the set level, the thermostat turns on. It opens the contacts, cutting off the flow of current to the compressor, causing it to stop. Work resumes as soon as the temperature reaches the required level.
• In case the motor overheats, there is a thermal protection relay. When the temperature gets too high, a special part on the relay - a bimetallic plate - bends and opens the contacts, so that the cooled element then rises back and closes the contacts again.

Device diagram

Cooling in such devices is carried out in several ways:

• compression: the temperature is lowered due to the refrigerant (freon), which is capable of boiling when the pressure is lowered, taking heat from the environment; circulation occurs continuously: freon is compressed in the compressor, passes to the condenser for cooling, and then, after the pressure in the throttle is reduced, it is sent to the evaporator;
• adsorption: the circulation of the refrigerant is carried out under the influence of heat when heated by a heating element;
• thermoelectric: heat is taken from the cooled products due to the movement of electrons.

In domestic refrigerators, the most common is the first method, compression. Adsorption units are used less frequently. Thermoelectric cooling is mainly used in manufacturing equipment.

Let's consider the scheme of the device of a standard refrigerator. For separate control of the cooling of the freezer and refrigerator compartment in two-compartment units, a common compressor driven by a motor and a pair of evaporators are more often used. Cooling - in the condenser (serpentine), combined into a thermal circuit. To protect against contamination and remove moisture from freon, a zeolite cartridge (filter) is built in. The transition of freon into a gaseous state occurs in the evaporator.

Refrigerator won't turn on

If a The refrigerator does not work, there may be several reasons for this:

• The device is not connected to the network, the power cord is damaged, or the lights in the apartment are turned off.
• A refrigerant leak also causes the refrigerator to stop working. It is almost impossible to accurately determine the location of the breakdown without special equipment, but there is one visual sign - there was swelling of the insulation on the outside on the back.
• Another reason may be the failure of the compressor or the failure of the breaker relay. A characteristic sign of a broken relay is a sharp loud click that is heard after turning on the refrigerator, after which it turns off.

If the matter is a temporary lack of electricity in the apartment or a loose fit of the plug contacts in the socket, then these problems are easily eliminated on their own.

If this does not help and the Stinol refrigerator does not turn on, unplug it from the mains and call specialists. Refrigerator won't turn off

There are several situations when the Stinol refrigerator does not turn off and continues to work for a long time without rest. In most cases, this is not normal, because the operation of the motor is cyclical, which means that the unit is regularly turned off and on.

The most common reasons why the refrigerator does not turn off:

The mode "superfreeze" or "quick cooling of products" has been set.

In this case, the freezer or refrigerator compartment will operate continuously until it reaches the default temperature. In this mode, the compressor does not turn off and continues to pump cold up to 8 hours in a row.

Violation of the sealing of the seal or an open door.

The refrigerator will always strive to reach the required mode, but due to the presence of warm air, the compressor will work all the time. An indirect sign is frost around the perimeter of the door.

Failure in the control system or failure of the temperature sensor.

A special sensor inside the freezing chamber or refrigerator compartment determines the current temperature and, when the set value is reached, sends a signal to the control module, which instructs the motor to turn off.

The main reasons why the refrigerator cannot start

To begin with, it is important to understand that you should not try to fix the refrigerator yourself. The attempt is unlikely to succeed, and the consequences can only get worse.

The risk is not justified at all. The easiest way is to call a master who has the appropriate qualifications and will professionally cope with the task.

Only the master will be able to identify the breakdown and make a quality repair.

Of course, there are cases when the reason why the refrigerator does not turn on can be eliminated on your own. However, this is still a very rare exception to the rule. In order not to aggravate the situation, it is necessary to understand the main causes of the breakdown of the refrigerator.

When contacting a service center, you can count on a quality repair.

Experts identify several types of malfunctions in the operation of freezing equipment.

Refrigerator not freezing well or not freezing at all

There can be several reasons for such a breakdown:

• a skewed or loosely closing door;
• another possible reason is the deformation of the door seal (this is a common cause of breakage in old refrigerators; in this case, the seal must be replaced;
• problems in the operation of the thermostat (in this situation, it is necessary to adjust the thermostat);
• the performance of the compressor motor (in this case, it is necessary to fill the motor with freon, or a complete replacement of the motor).

Refrigerator gets very cold

In the event of such a breakdown, two reasons are common:

• accidentally pressing the button that is responsible for the freezing function (in this case, you can simply disable this function);
• refrigerant leak or clogged capillary tube (only a specialist can solve this problem).

If the refrigerator starts to work incorrectly, you must immediately call the master, do not wait until major repairs are required.

Refrigerator leak

• Most often, leakage occurs due to clogging of the drain pipe, it must be cleaned;
• another possible reason is a breakdown of the compressor or thermostat, these malfunctions lead to the accumulation of water inside the device.

Refrigerator randomly shuts off and won't turn back on

• It is possible that the power cord or electrical plug is faulty, but only if the light inside the refrigerator does not work;
• one of the elements is out of order.

Loud noise during operation

In case during Refrigerator operation makes various sounds, for example, humming, clicking, crackling, then the malfunction is most likely in the motor, more specifically, in the compressor suspension.

Before you start repairing the refrigerator, you need to make sure what exactly needs repair.

Problems with the No Frost system

One of the last Stinol refrigerators that came off the assembly line in Lipetsk were models with the No Frost automatic defrosting system. During operation, the main malfunctions appeared, which have the following symptoms:

The freezer hums.

Most likely there were problems with the defrosting system, and frost began to form on the back of the evaporator. The fan, which evenly distributes air inside the freezer, begins to rub against the snow coat, which causes extraneous sounds. Replacing the defrosting heating element solves this problem in most cases.

Inside the refrigerator is noisy, beats are heard.

In this case, the most likely cause is a fan failure.Constant rotation leads to natural wear of the bearing group, the first sign of which is beats and noises. It is recommended to replace the fan before it completely fails, otherwise there will be no uniform distribution of cold air inside the chambers, which can lead to electronic failure.

The most common malfunctions of Stinol refrigerators

What to do if the Stinol refrigerator breaks down? Do not rush to call specialists, because many malfunctions can be eliminated on their own, because they are caused by our carelessness or violation of operating conditions.

The most common signs of breakdown of two-chamber refrigerators Stinol include:

• Refrigerator does not turn on.
• The compressor is constantly running.
• Refrigerator does not freeze well.
• The light is not on or there are problems with the indication of the bulbs on the control panel.
• Problems with the No Frost system in the freezer.
• Water flows in three-chamber and two-chamber refrigerators with the “weeping wall” system.

There are a lot of reasons for the occurrence of certain malfunctions, so let's look at each option in more detail.

Device Features

The refrigerator device from this manufacturer differs depending on the model chosen:

1. Refrigerator Stinol 107. It is equipped with a freezer, which is located at the bottom of the refrigerator. Control system - electromechanical, with 1 compressor, 2 chambers and 2 doors. This model has the No Frost option (defrosting the freezer evaporator in automatic mode).
2. The scheme of the refrigerator Stinol 102 includes such elements as: supports, plinth, guides designed to drain excess liquid, control panel, lighting devices, compressor, suction and capillary pipes, evaporator, condenser, filter. The total volume of the refrigeration device is 320 liters, of which 200 liters is a cabinet, and 120 liters is a freezer.
3. Stinol 110. This is a two-chamber white refrigerator with 2 doors and 1 compressor. The class of electricity consumption is C. A drip system for defrosting the chamber is installed here, there is a super-freezing option. Inside there are 4 shelves and 2 opaque containers for storing fruits and vegetables. Dimensions - 0.6x0.6x1.85 m.
4. Stinol 103. This is a refrigerator with a total volume of 340 liters. The freezer is located in the lower part of the body, defrosting is manual (drip defrosting system). The inner part of the door has 3 shelves, and the main part includes 4 shelves and 2 containers made of transparent plastic.

Refrigerator won't turn on

If the Stinol refrigerator does not turn on, then the operability of the outlet and the integrity of the power cable and fuse are checked. If the power circuits are normal, then it is required to check the operation of the compressor motor. When the windings are connected directly, the motor should turn on. The appearance of a hum indicates a jamming of the bearings of the rotor or pump.

If the motor works during direct switching, then there is a failure in the control system or a breakdown of the temperature sensor. For example, in installations with 2 compressors, after 5-7 years of operation, fatigue failure of thermal regulators occurs. A broken thermostat does not allow you to turn on the cooling mode or the motor runs continuously, not responding to the position of the regulator knobs.To restore the functionality of the unit, it is necessary to replace the thermostat.

sealing seal or open door

A rubber edging is used to seal the internal compartments. If the insulation is poor, the temperature of the air in the chamber increases, which leads to an overload of the compressor. Additional causes of overheating are the overflow of the refrigerator compartment with food or the frequent unlocking of the doors. To eliminate the breakdown, it is required to check the condition of the rubber seal and remove foreign objects from under the edge. Additionally, you should wipe the case from traces of fat, which impairs sealing.

If the refrigerator compartment does not cool well, and the freezer works, then it is necessary to check the correct installation of the equipment. When the chassis is placed on an uneven floor, the door is warped or does not fit snugly into the opening. To eliminate the defect, it is required to adjust the position of the refrigerator by rotating the screw front supports. The case is installed with a tilt back, which ensures automatic closing of the door and keeping the shutters in the locked state.

Super Freeze or Fast Cooling

In part of the Stinol two-chamber refrigeration units, an accelerated cooling function is provided, which is launched by a separate key. When the mode is activated, the compressor drive is constantly working, which ensures a decrease in temperature in the refrigerator compartments. The mode is turned off by pressing the key or by a signal from the automatic timer.

Results

Stinol refrigerators are fairly durable equipment with a good margin of safety, however, they are also capable of failing after a few years of operation and not working as intended by the manufacturer. A typical breakdown of such equipment lies in the fact that one of the chambers, mainly the upper one, stops cooling. The problem can be for many reasons, but the most common of them is the failure of the thermostat and the leakage of refrigerant. If you have a spare serviceable part, the thermostat can be replaced with your own hands, but it is up to the refrigeration repairman to solve problems with the refrigerant and violations of the tightness of the pipeline.
