There was also a problem, although it was not completely solved. The fuse burns constantly. It is non.standard and is decent.

Hello! The problem came out this morning. When the ignition is turned on, the radiator fan is triggered. It works even when I turn it down and take out the ignition keys! Until I disconnected the power, the chip to the fan. If I understand correctly, then the sensor of turning on the outline of the radiator is turned off?

Nissan777, if it twists with a shut.off ignition, then change the fan relay (the black box at the hydraulic power barrel) got the contacts and the relay was stuck in the relay.You can call it or disassemble it and everything will be visible.After that, everything should fall into place when the off. ignition, then, if you start and turn on the fans immediately (in this case, the conde button is off.), then look at the sensor (with an unspoken sensor, the check also lights up in prison).It’s easier to connect the computer and it will immediately be seen that the sensor shows and whether it is business.Well, then the last option to watch the wiring of the screws and call two fan relay control wires.

Preparatory measures for replacing the stove

Since all generations of Nissan Primera need to disassemble the front panel to get to the stove, it is worth considering the sequence of the procedure on a specific example.

The third generation will be taken as the basis, since it is the most relevant and common. There are no special differences in disassembling the early versions of Nissan Primera. The principle is the same everywhere. to remove everything that interferes with the extraction of the radiator of the stove, disconnect it, replace and collect the salon in the reverse order.

Prepare the necessary tool in advance, and also free at least 5-6 hours for work. In a hurry, it is strongly recommended to disassemble. You can make a number of errors.

The most difficult thing, according to the owners of Nissan Primera, is the extraction of the heater itself and installing the node in place. It is difficult to confuse something with the connectors, since there are only 2 identical connectors connected to servo drives. Plus do not forget about the sensor of the intensity of the sun, which is located on the windshield on the right. There is a round plug on the torpedo. Hinging it, you will see a sensor resembling a diode light bulb.

The set of tools is minimal. These are a few screwdrivers of curly and flat type of different sizes, as well as keys to 8, 10 and 13. Plus, take the pliers.

How to connect a fan in the bathroom to the switch. 3 errors and connection circuits.

Connection of the hood fan in the bathroom can be performed in several ways.

But the most correct thing is to do this through the light switch installed on the lighting in the bathroom, or through a separate keyword key.

The first options have a lot of inconvenience, at first not entirely noticeable.

For example, you mounted the hood on the door opening sensor. At the same time, it turns off the timer after 5 minutes. It would seem very convenient.

However, it is quite problematic to install such a sensor on the interior door. Not to mention other moments of operation. For example, what to do if you stayed in the toilet longer than the time spoke.

Open and close the door again? And if guests are in the kitchen?

In addition, the cable will have to lead under the tile, drill several extra holes, etc.P. Simple motion sensors are capricious to humidity and very quickly fail.

We will have to select expensive models with appropriate protection for IP humidity, according to the zones in the bathroom.

Someone considers the most convenient option to install the switch on the hood directly inside the bathroom. However, PUE prohibits it to do it.

Why is this so, relevant links and explanations of Rostekhnadzor specialists will be given at the end of the article.

Therefore, consider the most correct and reliable way. Connection from the lighting switch located on the outer side of the bathroom.

For installation, you will need very few materials:

Which one is better to choose, read in the article “The best cable for nym or vvang-ls”.

The body of most hoods is plastic, so such models do not need to be grounded. If you have ventilation with metal elements, then 41.5 mm2 2 residential cable will already be required here

The loads here are small, so these are controversial for many terminals, it will be quite appropriate here. No twists with subsequent welding, soldering or crimping do not need.

In our market, the most popular model Era is. We will consider it in more detail.

Other mechanisms and models with a timer from Vents, Ballu, Electrolux are connected in a similar way.

Here are the technical characteristics and detailed data on all popular models:

Electrolux EAFM-100TH ERA SB D100 Optima Vents 100 K Domovent 100 C Era D 100SC Ballu Green Energy Era D 100c et Vents 100 Quiet

Such fans with the timer have two operating modes:

Switching modes is carried out on the control board in the upper right corner.

There are similar jumpers from other manufacturers.

When working in the “toilet” mode, after turning on the light and feeding on the board, ventilation immediately begins to work. As soon as the light is turned off, the fan does not stop, but a certain time will continue to spin.

This time you set yourself, twisting the adjusting screw with a screwdriver.

How to organize cooling in a gaming computer correctly

The use of even the most effective coolers can be useless if the air ventilation system is poorly thought out in the computer case. Therefore, the correct installation of fans and components is a mandatory requirement for assembling the system unit. We explore this issue on the example of one productive gaming PC

This article is a continuation of a series of introductory materials on the assembly of system units. If you remember, last year the step.by.step instruction “How to assemble a computer” was released, which describes in detail all the main points for creating and checking the PC. However, as is often the case, the nuances play an important role in the assembly of the system unit. In particular, the proper installation of fans in the housing will increase the efficiency of all cooling systems, and also reduce the heating of the main components of the computer. It is this issue that is considered in the article further.

I warn you right away that the experiment was carried out on the basis of one typical assembly using the ATX motherboard and the MIDI-Tower form factor body. The option presented in the article is considered the most common, although we all know very well that computers are different, and therefore systems with the same performance level can be collected by dozens (if not hundreds) of different methods. That is why the above results are relevant exclusively for the configuration considered. Judge for yourself: computer buildings even within the framework of one form factor have different volume and number of seats for installing fans, and video cards even using the same GPU are collected on printed boards of different lengths and equipped with a different number of heat grips and fans. And yet certain conclusions are our small experiment to draw completely.

On the Internet you can find a large number of articles about the organization of cooling in the system unit, but many of them are written in those distant times when computers with the upper power of the power supply and a large number of baskets for 3.5- were considered standard (typical, classic, and so on) and 5.25-inch devices. Well, recently, standards have changed noticeably. This fact is clearly shown in the article “A computer that you could collect, but regretted money. the best buildings, PSU and cooling of 2017”. Trends, if I do not confuse anything, according to the transformation of standard Tower Corps, began to be traced back in 2014, but only now they have become a mass phenomenon.

An example of the assembly in Thermaltake Versa N27

So, a computer case with a landing place for installing a power supply in the upper part in 2018 can be safely called a curiosity. Typically, such devices are located in the price range up to 2,000. In most other PSU Tower Corps, it is attached from below, moreover, recently it has been hidden completely behind a decorative damper. There, under an impromptu curtain, sometimes placed a basket for hard drives. For example, in the last five reviews at the time of writing an article on our website, it was precisely such models that were considered.

In my opinion, first of all, corps manufacturers act in this way based on aesthetic considerations, because the use took the use of the power supply, unused wires and HDD, in the presence of a window on the side wall, makes the system more noticeably sympathetic. In addition, in a PC with such a case, you can safely install a non.dairy power supply, since the unequivocated cables will not affect the appearance. And the curtain clearly separates the power supply from the rest of the components, which, in turn, has a good effect on its cooling. As you can see, we observe continuous advantages.

An example of the assembly in the Thermaltake Core X31 case

The dimensions of the Tower Corps have recently changed, however, undoubtedly, the internal “perestroika” was provoked, among other things, the change in user priorities. People practically do not use optical drives, and therefore there is no need in the 5.25-inch compartments in the case. Compact solid-state drives are increasingly installed in system units-SSD form factor M.2 do not need any baskets at all. Given the great popularity of online services and cloud storage facilities, there is no need to install a large number of hard drives in PC, so one or two hard drive can be fixed on the barrier wall of the case. Finally, more and more iron manufacturers produce bright, spectacular components with backlighting. Such a trend may not like it, it can enrage and irritate, but more and more manufacturers of buildings produce more and more original colorful models with a window on the side wall.

All of the above-mentioned design features of the new “classics” allowed, firstly, to gently lay wires and loops, which contributes to better air circulation inside the housing and less dust accumulation. Secondly, the absence of baskets for 3.5- and 5.25-inch devices increases the free space inside the case. For the same reason, we can install a larger number of fans that will work more efficiently. Actually, this is exactly what is observed in modern devices, since even in the body of the Mini-Tower form factor that support the installation of only the Mini.itx-material boards can be fixed on the front panel of at least two 120 mm fans. The MIDI-Tower and Full-Tower houses allow you to install three, sometimes four fans on the front panel and the same amount on the upper wall.

How to make a fan yourself

How to make an old cooler fan. If there is an old system unit, you can take it from there. Borrow and switch there. Even in order to make a home-made fan, you will need any holder for batteries. There are many of them, you can take it from some broken toy or something else in the same spirit. Of course, the batteries themselves will be needed in the amount of several pieces. It remains to connect all these components together, and a simple fan will be ready. If you do not want to bother with the holder, then you can use it to serve power with a regular USB port. The stand can be made of anything. It all depends specifically on your own imagination and what you have at hand.

You can, for example, make a stand made of ordinary hard wire, fixed on something. It is not so important what materials will be used, but how sustainable the whole design will be.

Another option, how to make a fan can be useful for enthusiasts. Computer disks will be an excellent tool for manufacturing. What else will be required? A motor from a simple toy, a cork remaining from champagne, some improvised switch and several batteries. We take the disk, and then make as many incisions as the blades will be required. It is necessary to leave about a centimeter before the inner edge. Then turn each of the blades slightly at an angle. Bent much better if the disk is heated, for example, over gas. Then it will be necessary to insert a traffic jam into his center. If you make a small puncture in its center, for example, with an awl, then you can easily put on the entire structure on some kind of pin. It will be necessary to make a leg. absolutely any object in the form of a cylinder, which is able to accommodate batteries and wires, can act in its role.

It will also be necessary to arrange the basis for the entire unit. it can also be any, the main thing is that it can be stable and can keep the structure. It remains only to add several additional tips. when cutting out the blades, you need to ensure that each of them is about 45 degrees. ultimately about 8 parts will come out. The plug inserted into the center of the disk will need to be fixed with glue. In any case, the process should not cause you any difficulties.

If you thought about how to make a fan, now you probably understand that it is very simple. Each of the proposed models is extremely simple to manufacture, and you will not need much time to create it. No special things that are quite listed above are needed. Such fans are very convenient and differ in compactness. You can put it on your desktop. Or, if there is such a desire, take with you to the garage or to the cottage, where these devices will be cooling. It is difficult to argue with the fact that they have a tangible dignity-after all, these, by and large, are collected, very useful things from different trash.

Option #2. a product from a soft polymer

We will prepare in advance everything that we will need during the work:

• two bottles of lemonade “Sevenup”;
• electric motor 12 V DC;
• seven thick tubes for drinks;
• Sitter connector for power supply;
• the power supply itself;
• switch;
• scissors and household knife;
• marker;
• thermoclay pistol;
• Super glue;
• plastic screeds;
• Kusachki;
• soldering iron;
• insulating tape;
• CD disc.

So, there is another version of the construction of a home.made fan from a plastic bottle. Take a bottle of smaller capacity, for example, from under the lemonade “Sevenup”.

The algorithm of cutting the blades of the future propeller is the same as in the previous version. The plastic of this bottle is much softer, so you can give the desired slope to future blades without resorting to their heating.

The hole in the center of the traffic jam should be made using an awl or nail heated on this purpose for this purpose. The electric motor 12 V DC, on the shaft of which the propeller will be fixed, can be taken from old toys or a hairdryer unnecessary in the farm.

The lid on the shaft is performed using a thermoclay. We fasten the light propeller to the lid right away.

The most interesting thing is the construction of the stand. It turns out not only stable, but also attractive. To create it, you will need seven thick drinks for drinks. It is necessary to glue them with a superglue among themselves. It turns out a rather strong and pretty stand.

For the base, take the upper part of a larger plastic bottle than the one from which we made a propeller. Put the rack from the tubes into the neck of the workpiece, approximately to the middle of its length. We fix the rack in this position using a superglide applied to the neck of the workpiece.

Now you can install the engine on the rack, fixing it with a thermocle. The fact that the stand itself consists of hollow tubes helps to beautifully hide the wires. We just let them through the central tube. So the wires are inside the base of the device.

In order to additionally strengthen the structure, you should use plastic screeds that are glued with a heat mum to the rack on the sides of the motor so that the screed lock is tightened over the engine itself, ensuring its immobility. Extra fixing tip is removed with nippers.

In the plastic surface of the bottle, which serves the base of the structure, holes are cut out for the power connector and the circuit breaker. Make it better with a household knife.

Connect the power connector for the power supply and the switch. The wires should be soldered and isolated. The switch and the connector is fixed to the plastic heaters.

To weight the bases and make it more stable, we will build for it the bottom of the CD disk.

For this, the edges of the plastic blank are lubricated with heat mum and press the disk to it.

To make sure that you correctly understood the sequence of work performed, watch the video at the end of this article.

Nissan Primera stove malfunctions

Although Japanese cars are considered almost a model of reliability and longevity, they are also subject to wear and aging. The heater of the salon is no exception. It consists of several nodes: a radiator, an electric fence, a duct system and a control unit, and the most loaded part is a fan, whose task is to pump air into the salon (cold. in summer and hot. when it is cold). It is he who is subject to breakdowns to the greatest extent. And although the manifestations of the non.working stove as a whole are similar. cold in the cabin and permanently fogged glasses, different malfunctions can lead to such consequences, from a blown.out fuse to a breakdown of the Nissan Primera P12 stove itself.

How to find out that in the deterioration of the microclimate inside the car, the stove motor is guilty? Unlike other types of malfunctions associated with the absence of heat (output and building pumps, thermostat, stove radiator, the appearance of an air cork, antifreeze leakage) in this case, hot air will enter the salon, but in a limited amount or general. So the main symptoms of the motor of the motor are quite obvious:

• When the fan is turned on, nothing happens, while leaning the hand against the deflectors, powerfully feel the subtle movement of hot air;
• The fan works only at maximum speeds, that is, it does not respond to speed switching;
• When the electric engine is turned on, various sounds such as a rattle, creaks or squeal are heard, which can last a short time, eventually becoming longer and louder.

In the second case, we can confidently argue about the failure of the thermoresistor that protects the heater control unit from overheating.

In the absence of signs of the fan’s life, you should check the integrity of the fuse, then make sure that there are no problems with the power of the motor (connecting the power supply to the plus terminal directly from the battery). And only if everything is in order with this, you can sin on the electric motor itself.

Nissan Primera salon heater

So, if the stove fan does not start on your Nissan Primera, the reasons may be as follows:

In this case, it is recommended to dismantle a faulty motor and replace it with a new. But by virtue of the “biting” price for the original spare part (from 3 thousand), many car owners prefer either a replacement for a cheaper analogue, managing even to establish the products of the AvtoVAZ concern, which requires alterations, or perform an independent repair of the failed spare part.

Very often the appearance of unpleasant extraneous sounds that speak of wear of the sleeve, and then troubles with a motor breakdown, can be avoided by performing the appropriate restoration work. True, repair of the PRIMERA heater engine requires a fairly high qualification. Some motorists change the bushing bushes. as practice has shown, such a solution in most cases is ineffective.

In any case, regardless of whether you intend to repair the stove motor or change it to a new one, you will need to dismantle it. Let’s describe how it is done.

Heater motor

Stove control unit and damper drives

Nissan Primera has a fairly high.quality heating and air conditioning system. But a long term of operation, the human factor and even factory marriage can make their changes.

The stove may not work, since the control unit itself, located in the cabin, was out of order. There could arise problems with wiring, buttons and regulators would break. Sometimes it makes sense to disassemble the block and check if there are cliffs of cables or problems with the shift drive.

Turning the regulator or by pressing the button, the driver selects a blowing mode, that is, from where the air will blow. And if the drive, cable or wiring connecting control elements with performing mechanisms will fail, then the stove will not work.

It is worth recognizing that such a malfunction is rare. Therefore, not all owners of Nissan Primera are faced with her. But if, in diagnosis, all other potential and more likely causes were excluded, then it really makes sense to check the operability of the stove control unit, drives and damaste.

Also, rare breakdowns include violation of the tightness of the stove body. Due to this case, the air does not go outside, but circulates through the car of the car using air ducts. If the case turns out to be broken, the hot air will simply begin to go out and it will not be able to enter the salon. This usually happens after accidents, clashes, or from an accidental entry of the subject into the case. Although, given the location of the heater body in Nissan Primera, the last option is almost impossible.

Computer cooling errors

Often, newcomers during the assembly of PC make a number of errors when designing a cooling system. If it works incorrectly, it will be ineffective and meaningless in terms of spending money.

Therefore, the main rule of installation is to know where the cooler is blowing. The most common mistakes in computer cooling:

• You installed only the rear fan, which works on the “blossom”. Warm air, which when exit from the power supply is returned to the housing, and the components at the bottom will overheat.
• There is only one front cooler in the case, working for “blowing”. Reduced pressure leads to the formation of a large amount of dust. Heat discharge does not occur, the fans work at the maximum, the computer heats up and makes noise.
• The cooler, located behind, works for air blowing, and the front. to blow out. Warm air rises only up, and below it is cold. Incorrect circulation leads to overheating, and the effect will be like in the previous paragraph: a lot of noise, and the rapid wear of the components.
• Both coolers work for a blowing. Fans work for wear, quickly fail and pull the rest of the components. From this arrangement of fans, as we see, it is also to the point of zero.
• Both coolers blow air. This situation is the most dangerous for a computer or laptop! The pressure in the case is reduced, the air circulates poorly, all boards overheat and fail. Over time, the car can be thrown into the garbage.

As a result of the article I want to say that there are no fans in the housing. The larger there are, the lower the temperature inside the system unit. But each subsequent increases the noise in the room.
