Scheme and device of the VAZ 2107 stove

Find the node itself

The stove drive on the VAZ-2114 is located in the same place as in previous models of this car - in the center of the front torpedo. It is protected by a plastic cover that prevents dust and dirt from entering.

The principle of operation of the unit is based on the supply of warm air to three directions: legs, interior and windshield. A breakdown of the stove fan entails the problem of warm air entering the passenger compartment, leaving it near the radiator. Thus, the efficiency of the entire system becomes zero.

It is very easy to diagnose a breakdown: by turning on the stove and operating the knob for switching heating modes, you need to make sure that there is a specific fan noise and warm air supply (with a heated motor). If the sound is not heard, the fan of the VAZ 2114 stove is broken (but subject to the presence of power supply to this unit).

What kind of wood is more suitable for firewood?

Different types of wood differ from each other in calorific value and combustion characteristics. In this regard, when choosing a fuel, you need to understand the performance characteristics of firewood.

  1. Pine has a high burning temperature. The reason for this is the high resin content. This rock assumes many voids where resinous deposits are present. Burning down, they produce micro-explosions, sparks and burnt pieces of wood scatter.
  2. Spruce in the firebox is less efficient than pine. It contains less resin. Chopping wood is easy, but when burning, the tree smolders and smokes. These conifers can only be drowned in extreme cases.
  3. Alder. The main feature is the ability to burn without forming soot. At the same time, during combustion, deposits in the chimney will be burned out. Such characteristics are inherent only in aspen.
  4. Poplar. It burns out quickly, not giving enough heat. It should not be used to heat a bath, but it is quite suitable for a home.
  5. Birch. It burns hotter than beech with acacia and oak. But there is also a drawback, moreover, a significant one. It is necessary that there is sufficient air flow into the combustion chamber. Otherwise, there will be no heat, but only tar and smoke on the walls of the chimney.
  6. Oak. Differs in high density ability to generate heat. In its characteristics, it is similar to ash, and also resembles beech. In chopping, oak firewood is quite heavy.
  7. Maple. Its wood burns quickly without forming coal, as a result, it becomes necessary to constantly add fuel. It looks like a stove with linden wood.
  8. Apple trees. Like other fruit breeds, it pricks well, emits enough heat when burning. Apple wood is also preferred because of the pleasant smell in the room.

Causes of malfunction

There are several factors that can cause a malfunction. For example, it may be a commonplace problem with the F7 fuse, which may blow. It is easy to diagnose such a problem - this fuse is responsible for lighting the glove compartment, cigarette lighter and heating the outside mirrors. If the indicated devices do not work, it is necessary to replace the fuse.

The problem may lie in the oxidation of the contacts of the mounting block. If there are visible signs of oxidation on the surfaces of parts, it is most likely that this is the reason for the failure.Oxidation traces of contacts are eliminated with simple alcohol, after which they must be thoroughly dried. If a similar problem has arisen, it is best to pay attention to the contacts of other power systems - perhaps there are also traces of oxidation there.

The ignition relay can also be the cause of the stove fan failure. The relay should be checked if, with a warm engine, the stove refuses to warm up the air and supply it to the passenger compartment.

A problem often occurs when the stove does not work at the first or second speed, but works well at the third. This is due to the problem of a special resistor that is responsible for controlling the power supply at the first two speeds. The third speed of rotation of the fan is a direct current supply to it, therefore, in such problems, an additional resistor should be checked.

Problems may lie in the very design of the stove motor. It is possible that somewhere the contact between the wires has disappeared or there is a sticking of the brush. This must be checked visually by opening the casing and carefully examining the assembly.

A broken switch is also a common cause of stove failure. Everything is simple here - it must be replaced with a new one. The switch problem can be easily identified by removing the plastic cover itself and trying to switch the mode directly.

Finally, the main factor in the malfunction is a broken fan. Here it is necessary to disassemble the entire unit and remove the failed part. This reason, if not the most frequent, is one of the main ones, in which a complete dismantling of the unit and its replacement is required.

Airlock

The problem is related to a defective expander cap and insufficient coolant level. Factors affect the cooling system, which accumulates excess air, creating an air lock. Due to insufficient circulation at low speeds, the stove blows cold. The air heats up when the speed is increased, and when stopped, it cools again. What to do? Eliminate the root cause: as in the case of a system depressurization, add antifreeze, replace the expansion tank cap, purge the system, blowing out excess air. The air can be removed by standing on an overpass so that the front wheels are higher than the rear wheels. Open the expander cover. At this moment, the air will come out accompanied by a characteristic sound ("gurgling"). The coolant will also go away, so it is important to top up it to the correct level. After this procedure, it is likely that after a while the airlock will form again. This is the fault of the burned-out cylinder head gasket. But in this case, the stove does not work well, not only at idle.

Replacing the fan of the VAZ 2114 stove

The fan is the main part of the stove, which most often fails. Replacing it is not very difficult, but you should adhere to certain rules. During the replacement process, you do not need special tools - you can get by with the simplest set of car repair kit.

  1. We de-energize the electrical circuit by disconnecting the negative terminal of the battery.
  2. Disconnect the positive power cable of the motor under the dashboard.
  3. In the engine compartment, unscrew the two bolts that hold the stove cover.
  4. Disconnect the "mass" - unscrew the wire fastening bolt.
  5. We unscrew the two bolts that attach the fan directly to the stove body.
  6. After that we dismantle the air duct grill.
  7. We take in our hands the motor of the VAZ 2114 stove and pushing towards ourselves, we disengage it.
  8. By turning the part 90 degrees, it can be easily removed from the casing.

The assembly of the assembly is carried out in a similar sequence, exactly the opposite.The procedure is not particularly difficult, but you should pay attention to the correct fixing of the power supply contacts so that you do not have to disassemble the unit again.

Many motorists were faced with the fact that the stove fan on the VAZ-2114 failed. But, not all of them know that it is easy enough to replace it with their own hands, and it is not necessary to pay a small amount to a car service. On average, the entire process will take up to half an hour and will save you significant money.

Stove design

The interior heater is made up of two plastic covers (left and right). They are connected with fixing brackets. A sealing strand is placed in the grooves of the structure. An electric fan is forcibly pumping air into the passenger compartment. It is secured with two screws on top of the stove. It is easily accessible from the side of the combustion engine.

The fan of the stove is driven by the impeller of the electric motor. The VAZ 2109 stove motor has two resistor spirals, which provide three options for rotation speed. The stove circuit includes an additional resistor to obtain the desired speed. The radiator consists of cooling fins, two rows of tubes and two plastic tanks.

The stove is controlled by three handles. A bracket is attached to the dashboard, on the axes of which these handles are installed. The stove control lever acts on the radiator valve lever and the damper drive lever. If the walker is taken to the right to the maximum, the damper and the tap are fully open - and the VAZ 2109 heater fan supplies air to the radiator, in which the heated antifreeze or antifreeze is driven. Accordingly, if the handle is in the middle position, the damper and valve open halfway - and the air becomes not so hot.

Moving the lever to the extreme left position, we get a completely closed valve and damper. The stove is blowing cold air.

The process of replacing a fan on a VAZ-2114

Heater fan

As already mentioned, the process of replacing the stove fan will take quite a bit of time and even a novice motorist can do it.

The unit itself is located in the engine compartment, behind the engine shield. From the ingress of dust and dirt, it is protected by a plastic casing, which performs its functions well, but not always.

Before proceeding directly to the replacement process, it is necessary to collect the toolkit. So, let's consider what is needed: a set of keys (where without it), a screwdriver with a Phillips tip and a new fan, as a part, are required.

Exact withdrawal algorithm

Now that the motorist is fully armed, you can consider the step-by-step instructions for replacing the stove fan:

Fan selection

Now that the process is clear and considered, it is necessary to consider which stove fan is suitable for the VAZ-2114. To do this, first refer to the spare parts catalog. In addition to the original spare part, a number of analogs were found that were recommended for installation.

Original spare part (article)

2108-8101078

- the original catalog number of the stove motor for the Lada family of cars 2108-21099, as well as 2113-2115. It is made at the AvtoVAZ plant and the average cost is 2,000 rubles.

Analogs

In addition to the original stove fan, there are several analogs on the market that are recommended for installation.

So, let's consider all the possible options:

Unfortunately, no other analogs have been found, but some motorists are modernizing this unit by means of alteration.

Complete assembly

Or they buy the whole spare part assembled, here are the articles:

conclusions

Replacing the stove fan with a VAZ-2114 is quite easy and simple. As practice shows, most motorists do just that, saving their time and money. But, if the process seemed very difficult, then it is recommended to contact the service, where they will do everything quickly and efficiently.

If you hear extraneous sounds during the operation of the car's heating system, then in the overwhelming majority of cases, the stove fan is to blame and needs to be changed.

In fact, replacing the VAZ 2114 stove fan is a rather trivial task that most car owners face several times during the operation of each individual car taken.

Recall that the previous article was about do it yourself.

At the same time, a beginner himself is unlikely to be able to quickly figure out how to correctly replace a broken part, therefore, we decided to publish this article so that it would be easier for all those who did not encounter a similar problem before to fix it and did not need to spend extra money on payment for the work of the master.

How can I identify the specific cause of a fan failure?

As mentioned above, replacing a fan with a "fourteenth" is a fairly simple task that any savvy car owner can handle. But before proceeding directly to the work, you should understand what is the reason for the malfunction of the heater fan. To do this, you must start the car and turn on the stove, switch the intensity of the heater and listen to how it works at the 1st, 2nd and 3rd speeds.

If you hear extraneous sounds, or vice versa, hear nothing, then the problem lies in the fan itself. If at the first two speeds there is no sound, and at the third it appears, then the problem lies either in the switches or in the resistor, which is responsible for the normal operation of the heater fan.

For what reasons can there be a malfunction in the operation of the stove motor?

If you have definitely determined that the stove fan is not working, then you need to think about the reasons why the start of the motor that spins it does not work. There are several typical reasons, which we will describe in more or less detail below:

1. Blown fuse. To begin with, you need to understand that the fuse marked F-7 is responsible for the operation of the stove motor. He is also responsible for headlight washers, heated mirrors, cigarette lighter and a number of other electrical devices in the car. If it really is the problem, they should stop working as well.

There is nothing difficult in replacing a fuse, only this, most likely, will have to be done regularly, since it does not burn out for a reason. Therefore, before replacing the fuse, you must "ring" the electrical circuit of the car and find the place where the short circuit occurs, which leads to the blown out of the fuse.

2. Poor contact in the mounting block. Everything is simple here, either the contact connection has worn out, which can be replaced, or the contact has simply oxidized, which is also easily corrected - just clean it with a file or sandpaper.

3. Sticking occurs in the ignition relay. To understand that it is the ignition relay that is to blame is quite obvious - the stove starts only after the car is warmed up.

4. The stove motor resistor has failed. If you find that the stove works only at third speed, then in the vast majority of cases the problem is in the resistor. The thing is that at the first two speeds, the current is supplied through this electrical element, but at the third speed, it is already supplied directly to the stove motor.

5. The speed switch of the car's stove has broken. Some inexperienced drivers think that if replacing the resistor does not help, with the problems from the previous point, then replacing the stove motor will help. This is a big mistake, because it has nothing to do with it. If you are faced with that rare case when the stove works only at 3rd speed, and replacing the resistor does nothing, then it's time to deal with the switch. You need to use a light bulb with two soldered wires to check whether the electrical circuit as a whole is intact, and whether the fuse responsible for the switch is not damaged.

6. The rarest reason why the stove fan does not work is a problem with the motor. Here you will have to check if it overheats, if its high-quality contact with the mass of the fan is sufficient, if there is no sticking in the brushes of the stove motor.

The procedure for replacing the fan of the heating system "fourteenth"

Replacing the fan of the VAZ 2114 stove is a simple procedure, which we have already mentioned more than once above, but it requires a certain sequence of actions, concentration and accuracy. To make it easier for you to understand how to replace the fan in your "fourteenth", we have broken down the procedure into simple steps, following which you can easily complete the replacement yourself.

Step 1:

Open the hood and unscrew all the bolts that secure the plastic trim and set it aside so that it does not get in the way

Step 2:

Remove the gum from the bonnet

Step 3:

Dismantle the protective cover of the stove motor motor

Step 4:

Remove the two mounting bolts that secure the stove motor to the sides

When a car's stove fails, the fan motor is often the cause. You can detect such a malfunction by the characteristic sounds that occur when you try to turn on the heater.

Check

To make sure that it is the motor that is the cause of the heating system malfunction, a simple but indicative procedure should be carried out:

  • Start the car;
  • Turn on the first, second and third speeds of the stove alternately;
  • In the absence of sounds demonstrating the start of the fan, the motor is out of order;
  • If the fan did not turn on at 1 and 2 speed modes, but started working at 3, then a switch or an additional resistor may be the cause of the problem.

Breakdown reasons

The motor may not work for several reasons. Each of them requires separate consideration. Therefore, we suggest that you familiarize yourself with the possible reasons for the fan failure in our table.

Cause It's important to know
Blown fuse The fuse F7 with a voltage of 30A is responsible for the stove. Replacing it is not difficult, but the main problem lies in the possible occurrence of a short circuit. This fuse is responsible for the lighting in the glove compartment, headlight washer, cigarette lighter, heated mirrors. In the event of a malfunction, all of these devices will stop working.
There is no contact in the mounting block This is a common problem in cars that results from oxidation of contacts or loss of bond strength.
The ignition relay sticks The heater turns on only after the vehicle has warmed up. Therefore, it is recommended to check the status of the ignition relay in the event of an inoperative fan. Replace relay if necessary
The stove turns on only at 3 speeds 1 and 2 speeds are switched on due to an additional resistor, and in mode 3, the current goes directly to the motor. In this situation, replace the additional resistor or check its contacts.
The stove switch is broken Here we are talking about problems with an electrical target or fuse. To check their condition, you can use the control lamp
Problems in the design of the motor If everything is fine with the switch and the current, but the fan does not respond, you should check the level of overheating of the motor, its contacts with ground or brushes for sticking

Depending on the trouble you are experiencing, you may need to replace the fan. Changing the motor is not difficult, although for this you need to have a certain skill or at least minimal experience in working with the electrical equipment of your car.

The first step when replacing the stove motor is to disconnect the battery.

Even at the stage of searching for a house, I set a goal for myself - to buy a house with a Russian stove.I read on the Internet a lot of conflicting reviews and opinions about the Russian stove, some books and articles. And the more information I learned, the stronger my desire was - to have a Russian stove in my house. First of all, there is a large number of dishes that can be cooked in a Russian oven. Also, an important role is played by the aesthetic pleasure of contemplating a live fire, unnecessarily becomes short, and sitting in a comfortable chair and sipping hot coffee, tea or, in case of severe frosts, warm mulled wine. Anyone, even the most advanced psychotherapist, will not give you that relaxation and vitality that the Russian stove gives you. Unless only a fireplace can compete in this regard, but even then, only if you have a supply of extra firewood.

“Don't you like cats? You just don't know how to cook them. "

Perhaps the same can be said about those who do not like the Russian oven. I admit that someone was simply unlucky and they initially got a structurally incorrectly folded stove. Hence the talk about smoke entering the dwelling, about low efficiency, cold floor and so on, so forth. But you must admit that a crooked stove-maker can do the same with a "Dutch", "Swedish" and even a stove-stove.

Having no prior experience of communicating with the Russian stove, I personally have to come to understand all the nuances of her soul, by trial and error, or simply by a scientific poke. I perfectly understand that for someone my discoveries are another invention of the bicycle, but I ask you not to judge strictly, until recently, a complete teapot in this matter.

So here are some of the discoveries that I managed to make:

First and foremost, besides the soul, the Russian stove also has character. Believe it or not, it is precisely the Russian character. About whom do they say that they harness for a long time, but go fast? The same thing fully applies to the Russian stove. It is not a heating device for summer residents who visit their home from time to time. It is difficult to get a quick return of heat from it, as, for example, from a "Swede", "Dutch" and even more so a potbelly stove. The Russian stove requires a special approach to itself, and it seems to me that this is why many folk signs related to weather forecasting have appeared. Today it is almost impossible to get a reliable forecast for the week, but it is quite possible for the next day. Based on the information received, it is necessary to regulate the laying of firewood, both by the number of logs, their caliber, and by types of wood. If a cold snap or strong wind is expected through the windows, I increase the number of logs and their size. I lay naturally birch trees, as the hottest ones.

I try to choose logs that are similar in thickness, degree of drying and less knotty. That would burn out at the same time and give a large amount of coal freed from carbon monoxide.

After closing the view, depending on the temperature in the room, I immediately close the damper in order to accumulate the received heat or leave the mouth open for some time so that the heat would dissipate around the room. Then I open it as needed, bringing the room temperature to a comfortable level. One flue of seven to nine birch logs of medium thickness is enough for a day to maintain the temperature in the room at least +20 degrees, with an outboard temperature up to -20.

All the more incomprehensible is the talk about the fact that in the room where there is a Russian stove, you need to wear felt boots and a T-shirt. Yes, during the heating of the stove, cold air is drawn into the room due to the draft in the chimney, and at this moment the temperature in the room even drops by 2-3 degrees, since air is drawn into the stove at the level of the hearth. But is air taken from somewhere else in furnaces with a grate and ash pan? There, in the same way, cold air is sucked from under the floor or through the available slots. After all, a vacuum is not created in the room with the "Swede" during its heating.

As soon as the view at the Russian stove closes, the temperature in the room immediately rises. Specially measured the temperature difference after the end of the heating at the level of 1.5 m. and on the floor. Each time I got a result of 2 degrees. If for someone this is a reason to put on boots, then what does the Russian stove have to do with it?

Since I have no experience in heating a "Swede", it is difficult for me to judge the difference in the gluttony of stoves of these designs. Compared with the "Dutch", the same amount of firewood is consumed per day. But other things being equal, the "Dutch" needs to be drowned twice a day, and the Russian is enough only once. A neighbor who drowns his potbelly stove also constantly recalls the gluttony of the Russian, but here's the firewood for a day, he carries for himself exactly the same amount as I do. At the same time, his chimney smokes three times a day, and mine only in the early morning.))) The same conclusion can be made by familiarizing yourself with the true, and not invented, efficiency of the Russian stove.

Tales about the low efficiency of the Russian stove

As proof of the groundlessness of rumors about low efficiency, I will quote from an article by A.E. Shkolnik, published in the journal "Science and Life" No. 1 1988.

“But nevertheless, despite the popularity of the Russian stove, it was believed that stoves that are fired with an open mouth have a small efficiency: 30 ... 35%. To find out the actual efficiency of the Russian stove, special tests were carried out. The results were stunning - even the traditional Russian stove showed an efficiency equal to 68%, that is, comparable to the efficiency of a modern solid fuel CHP. And in a Russian stove with a bottom heating, the fuel efficiency reaches 80%! "

Substitution

It is not difficult to change a failed unit. Follow certain rules and sequence of your actions in order to achieve the desired result.

  1. Disconnect the negative terminal from the battery.
  2. Raise the hood and, in the engine compartment, disconnect all mounting bolts that hold the plastic trim.
  3. For the time being, the cover can be removed to the side, so that it does not interfere with work.
  4. Remove the sealing gum, which also has its place in the engine compartment.
  5. Remove the protective cover of your heater motor. So you got to the object you were looking for and you can start replacing.
  6. There are two bolts on the sides of the motor that hold your fan in place.
  7. Now go to the salon, remove the panel from the driver's side. There is a positive plug, which must be disconnected.
  8. Next, look for the negative wire. It is held in place by one nut, which must be unscrewed.
  9. The disconnected wires are inserted into the hole in your car body, passing through the rubber band.
  10. Remove the damaged motor. To do this, you need to turn it and pull it out through the right side.

Follow the reverse assembly sequence carefully to avoid mistakes that could lead to even more serious problems.

As you can see, removing the device is not difficult. Having studied the state of the fan motor, we can conclude that it needs to be replaced. Sometimes car owners get by with a simple repair of brushes or replacing fuses.

Issue price

The price depends on whether you buy a motor complete with a housing or separately.

The motor itself will cost you about 500 rubles, and you will have to pay about 1000 rubles for the assembled device. Which option is preferable for you, decide for yourself.

Comfort in a modern car should be quiet. That is, all devices and devices that should work in silence should be silent, otherwise, as a result of the singing of the chorus from the air conditioner, heater, windshield wiper motor and washer, the sound background may not turn out to be the most conducive to travel. One of the soloists of this symphony may well be a stove fan, so we will consider some methods of dealing with it.

Stove fan price VAZ 2114

The heaters of VAZ front-wheel drive cars of the Samara family are arranged in the same way, and we will consider the VAZ 2114 as the quintessence of the development of stove heating of the interiors of Togliatti cars at the end of the twentieth century. A simple and fairly reliable Samar stove heats better than one might expect from it. And the repair and maintenance of the stove is inexpensive. The only thing that cannot be measured with money is the ergonomics of maintenance, dismantling and replacing the stove fan on a VAZ 2114. The fan is sold complete with an electric motor and a casing. And this is an ideal replacement option, although the price of the node quietly sneaks up to a thousand. A fan from Luzar costs about 900 rubles, and this is not the best fan manufacturer in the world.

And you will have to change the assembly, because the motor shaft and the turbine-fan itself are balanced and centered in the conditions of the assembly plant. This is where the main difference between a good fan and Luzarovsky lies. If the impeller is off-center, it will generate more noise than heat. In addition, it not only makes noise from constant vibration. Engine bushings fly from vibration, well, if they do not fly at all, then they serve much less than on a centered unit. Therefore, it is up to everyone to decide - the rumbling, grinding, squealing is more expensive and there is a high probability of being left without heating every minute, or spending 1,000 rubles on a normal fan.

Wiring diagram, resistors and fan relay

Changing the fan, in principle, is not difficult, but you will have to remember the service in the army and the vocabulary of the person on duty. We have posted the technical characteristics of the fan and its connection diagram on the page, if it somehow helps in dismantling. Just in case, if someone cannot find the original fan, then the engine must develop at least 4200 rpm with a current consumption of no more than 14 amperes.

Whistle and howl can be different at different engine operating modes. This is because the connection diagram assumes the presence of a resistor with a resistance of 0.23 and 0.65 ohms. One limits the current for low speed, and the other serves to obtain the second speed. But this is theory.

What kind of firewood is preferred?

It is best to take solid, hardwood firewood. When they burn, no resin is released, and the high combustion temperature is kept without problems. An additional plus is that soot remains to a minimum inside the chimney.

It is undesirable to heat the stove with garbage; it is also bad to use spruce and pine firewood. On the contrary, it is good to heat with sawdust. Briquettes are also used, they are made from peat or wood. The fuel should have a moisture content of about 20 percent. It is present if the wood is stored in a dry room for a year.

Where is it located and how to remove the stove fan

Practical exercises on dismantling a VAZ 2114 heater begin with determining the place of its deployment. If you go to the sound, then the heater together with the fan can be found under the windshield in the space under the hood. In general, the plant says that it is possible to dismantle the engine without removing the heater. For this, the following technique has been developed, which we are happy to share:

Further repairs and disassembly should be carried out only if there is no way to find a new engine assembled with a fan, and only if no one is going to remove the impeller from the shaft, otherwise, the entire unit will have to be thrown away, since the factory alignment will not be achieved under any circumstances. Checked.

How is it heated correctly?

To reduce the consumption of firewood and improve combustion, the stove-maker advised to do the following:

  1. Logs should be placed in the stove, which are about 5 cm shorter than the length of the firebox.If, when storing firewood, you make them approximately the same size, it will be much easier to heat.
  2. The logs are laid in such a way that there are air gaps.
  3. Although the stove can, in principle, be heated with raw wood, this is fraught with the release of tar with smoke and in considerable quantities. In this regard, it is better to deal with dry fuel (no more than 25 percent moisture).

And in conclusion - about how to start heating the stove.

Common Beliefs That Make Entrepreneurs Subordinates

Stop garbage

In some cases, it is possible to negotiate with the engine by lubricating the bushings with graphite grease. There is no guarantee that he will calm down, but you can try. Throw it away anyway. Fan noise, squeak and squeal can be attributed to more than just the engine itself. Often there is a banal clogging of the air duct and the ingress of debris into the fan. The meanness of the situation lies in the fact that it is almost impossible to check this without dismantling the fan.

And what do you want, you have to fight for warmth in the car. And if this warmth is also silent, there is no price for it. But nevertheless, it is better to try to prevent debris from entering the air duct, and then the VAZ 2114 will delight its owner with a warm and quiet interior. Good luck on the road!
