Main problems

To identify the root cause of the malfunction, you need to find out what parts the fan consists. Regardless of the type (floor or desktop), the device has exactly the same device. The difference is only in the length of the rack.

The problems of the fan are different, and each of them has its own reasons and signs.

The fan does not turn on

The device may not turn on, but in this case it is important to pay attention, the light bulb or not when trying to launch the device lights up. If the indicator shines, and the device does not turn on, then the block with the buttons that is located on the fan stance broke.

If the bulb does not turn on on the case, and the device does not make sounds, perhaps there is no voltage in the outlet, or the reason lies in the breakdown of the cord, fork. If it is impossible to launch a household appliance and the exclusion of the above reasons, the problem should be sought in the electric motor.

The blades rotate poorly

Blades can slowly rotate for several reasons. The main of them is the lack of lubricants in the sliding bearings. Sometimes the blades are deformed at high temperatures from the engine (when the device has been operating for too long, overheating occurs). In this case, the blades cling to a protective grid, so finding such a problem is simple and fast.

The fan does not turn to the sides

Most likely, his fasteners weakened, and you just need to tighten them. If the unit turns, but with a creak, that is, tight and with pauses, disassemble the fan housing and check the condition and adhesion of the gears in the gearbox. Make sure the switch moves freely up and down. It will be necessary to remove the shaft and the main gear in order to grease them. Collect everything lubricated back. With the wear of the gears, collect a fan without a gearbox. It will work in a static position. But it will be.

The cooler is buzzing and does not rotate

Many people mistakenly call the cooler a fan, but in reality it is a cooling device that may not have blades. The main purpose of the cooler is to remove the heated air from the fan. Sometimes he buzzes, but does not rotate. There are several reasons:

The fan makes noise and creaks

The case is the deformation of the propeller or the weakening of the sliding bearing fastener.

Remember, maybe you pulled it out in the sun and forgot it there or even dropped a lot and strongly. Disconnect the device from the network and begin to disassemble it. Inspect the protective grate for deformation. Perhaps the blades during rotation relate to its pressed parts. You can straighten all bends with your hands. Remove the propeller, inspect it and its blades. The topic is the same. Unlike the grille, straighten the polyurethane with your hands. We’ll have to change the propeller. If everything is exactly there, check the bearing fastener. Tighten all the bolts.

Despite some external differences in various models of fans, the principles of their device and repair are the same. Do not be sad if your fan breaks, do not rush to carry it to a landfill and look for a grandmother’s sink in the attic. Everything is not so difficult and most often corrective.

Other malfunctions

What else can happen to the floor and desktop fan:

  • Capacitor breakdown. In household fans, a dry type made of plastic is usually used, which is easily deformed due to overheating.
  • Electric engine malfunction. The main feature is that the device does not start or gives unnatural sounds.
  • Problems in the control unit. Most often the reason lies in worm gear and diffuser.
  • If there is a speed switch, then the fan may not work due to its malfunction. The reason is a break in windings.
  • Rarely failure of the fan is the rotor. This happens against the background of overheating of the motor.

Regardless of the cause of the malfunction of the floor and desktop fan, conduct an independent diagnosis, which will reveal the site and cause of the broken.

Do.It.Yourself floor and desktop fan repair

After detecting a problem with the fan, you can proceed directly to the repair. First prepare the necessary tools and materials depending on the type of malfunction. The first thing that is checked after the diagnosis of the cord, forks and sockets is the serviceability of the electric motor. Often the problem is the microcircuit, so first determine the level of flow rate on the fee and the output from the chip. In the absence of voltage, the problem lies in the breakdown of the microcircuit, which can be replaced.

See also  Electric convector dries the air or not

If the current goes to the microcircuit, and the floor or desktop fan does not turn on, you will have to disassemble the case and check whether the current comes inside. If not, the problem is the electric motor, so you have to give the motor for repair.

  • Disconnect the two wires connecting the electric power and the microcircuit;
  • Also do with 2 wires going from board to the motor;
  • Assume a new microcircuit.

There is an option in which the fan will work without a microcircuit, that is, directly, so the device will be included immediately after installing the cord in the outlet. To do this, do similar actions with wires, but instead of installing the microcircuit, they are connected to each other.

To understand how to make a fan repair yourself, you need to know the principle of operation of the device. Scheme:

  • Asynchronous type, installed on standard floor and desktop fans, has 8 launch and working windings;
  • To launch the phase is shifted by 90 degrees using the capacitor;
  • The launch is carried out after pressing the power button (first the red indicator turns on, after the electric motor begins to rotate);
  • The speed of the rotational moment is affected by a 3-speed switch that has mechanical locks of simultaneous speed switching.

Replacement of the rotor

The rotor is usually on the gasket under the lid or behind the shaft, so the engine is removed for its repair or replacement with screwdrivers. The first thing to do is to inspect the wiring that can be the cause of the malfunction. If there are no defects on it, you will have to change the rotor, since it is not possible to repair it yourself. Be sure to write down the number of the device and purchase exactly the same model.

  • Disconnect the wire leading to the rotor;
  • Unscrew the screws;
  • Remove the device;
  • Put a new rotor, tightly screwed to the base.

If the gasket is not deformed, it is pointless to replace it with a new option. Use the old element. Keep in mind that the rotor should not touch the electric motor.

How to fix a control unit?

The control unit breaks due to worm gear. This problem can be eliminated independently by following the instructions:

  • Remove the contact block (the motor does not need to be removed);
  • If there are gaskets for the managerial unit, remove them;
  • Twist the shaft with a screwdriver;
  • Remove the control unit;
  • Dismantle the lid behind, opening access to worm gear;
  • To check the performance, use the tester (without breakdown, the resistance parameters should not exceed 50 Ohms);
  • In case of violations, replace the old element with a new.

What to do if the flange broke?

In floor and desktop fans, plastic flanges are used, which are easily damaged, especially when the device falls. Therefore, replacement is required. How to do it:

  • Unscrew the rear cover near the motor or shaft depending on the model;
  • Remove the crank;
  • Disconnect the worm gear without removing the control unit;
  • Remove the switch;
  • Twist the screws from the flange and disconnect it;
  • In the reverse order, install the new flange.

If the model involves the location of the flange near the managerial unit, then first release the clamping bar, then twist the control unit, remove the gasket located near the rotor.

Fixing of the diffuser

Diffuser is in the control unit. The reason for its breakdown is to twist the regulator. Change it as follows:

  • Remove the top cover without touching the engine;
  • Disconnect the central flange;
  • Remove the control unit;
  • Remove the diffuser from the rear (Put the base with a screwdriver or knife);
  • Replace the new element.

It is problematic to buy a diffuser separately in stores, as it is equipped with a control unit, so in this case the entire block is most often changed.

Coler repair

If a part with a propeller and blades is broken, use the following tips:

  • With the usual deformation of the impeller against the background of overheating, it is necessary to extract the propeller, slightly warm the blades and leve so that they do not touch the protective grid of the fan.
  • If the blades are broken, you will have to buy a new propeller and install it yourself.
  • If a small part of the cooler is torn off, the fragments can be glued with reliable glue.

How to repair a capacitor?

The capacitor usually breaks due to unexpected voltage drops in the electric network. The part is located behind the central flange. The cause of the malfunction is the absence of a phase shift or a power to receive a winding. The main feature is no rotation. The capacitor malfunction is checked using a multimeter (measurement mode. Resistance).

Checking the fan electric motor

Let us consider in detail. How the fan motor is being checked. An example is an electric motor corresponding to the version of household desktop fans.

The photograph shows a small electric motor \ photo \ desktop fan. To state this topic more understandably, the clarification will be accompanied by personal photographs. For the diagnosis of the electric motor.

Diagnosis of electrical connections begins with a preliminary check directly by the device itself \ photo \.

Why is such a check is needed?. The verification is carried out to be convinced that the wires of the probe of the device do not have a gap. That is, in practice, such a malfunction of the device as a wire break in conjunction with the probe \ Metal pin in conjunction with the wire \ is often found.

With a break, \ for a certain section of the electrical circuit \ display of the device multimeter. Shows »Unit”. If the two probes of the device are closed together at the same time \ with the displayed range of the lowest resistance \, the device display will show the zero resistance value. For this example, this will mean that the device acting \ serviceable \.

The unit does not turn on

In this situation, there may be 2 options: a light bulb that means the readiness of the unit to work, can be caught or not. Depending on this, the algorithm for diagnosis of the breakdown will differ.

The bulb does not burn

If, after the device is turned on, the bulb located on its case does not light up in the outlet, and it does not start, then, first of all, it is necessary to check if there is a voltage in the outlet. It is done simply: take any electrical appliance and include in this outlet. If the device has earned, then you need to look for a malfunction in an electric fork and cord.

To check the fork, spin it and check the reliability of the connection of the wires to the terminals. To check the cable, it is necessary to disconnect it from the contact pad of the device and “call” the tester. If a cliff is detected in the cable veins, it should be replaced.

The bulb is on fire

The reason for this behavior of the unit, when the indicator bulb burns, but the fan does not work and no sounds can be heard, it can be caused by the blocking of the block with the buttons. To check the buttons, you need to disassemble the button unit located on the floor fan stance or stand near the desktop. But, before disassemble the device, make sure that it is turned off out of the outlet.

The work of buttons is very simple: there is a “vkl” and “off” position. Using the tester, check the “output” and “input” on each key.

If a faulty button is detected, it will not work to repair it. Therefore, the switch should be replaced or the connection is directly. This approach to solving the problem will help start the unit into work if you are far from the store, for example, in the country.

Faulty speed switches can also cause why the fan does not turn on. To check the regulator, you will need to put it in the maximum position and check the “entrance” and “output” using the same tester.

How to disassemble the fan. Instructions with the photo

How to get to the bushings without removing the engine? To get started, unscrew the central screw on the back wall of the protective casing.

Another self-tapping screw is hidden in the adjustment button for turning or stopping at the fan head.

After that, the back cover is easily removed from its place. What is under it? Here you can see the gearbox of the rotary mechanism that gives rotation to the whole head.

A special thrust is suitable for him from below.

The starting condenser of the engine is fixed on top.

By the way, keep in mind that in different models it may not be there. In this case, look for it near the speed buttons.

To access the engine bearing, you will need to remove the gearbox. It is attached on three screws, and properly propped up with a traction.

Twist the screws and disconnect the thrust. After that, the gearbox is removed from the shaft and you get access to the rear hub.

You don’t need to unwind anything else and disassemble. The rest will be made for you.

Put a narrow guide tube on the WD40 spray and several times pash in the gap between the shaft and the bearing.

After spraying WD40, turn the shaft with your hand in different directions and move it a little forward and forth.

Excess thickened lubricant, extraneous garbage and dust will gradually go outside. These excess dirt are easily removed with cotton sticks.

If you have a thick lubricant of the type of Cyatim or Litol, it is advisable to apply it to the gearbox worm. After these cleaning procedures, drip on the bearing on the outside a few drops of oil for sewing machines.

Just do not need to apply it through the chur a lot. Otherwise, it subsequently spreads in all places and dust sticks on it, turning back into dirt. As a result, you will again receive a wedge and a problem with fan rotation.

Near bushings in separate models put felt washers. They are impregnated with oil and when heated, the oil flows into the shaft, lubricating it.

PC FAN TEARDOWN

All in the reverse sequence. Traction. Three gearbox screws. External cover.

By the way, if through the chur tighten the central self.Tapping screw on the back cover, and this is exactly the screw, not the screw, it can pass through the plastic of the rotary gearbox and rest in the shaft.

You will again have problems with turnover and jamming. Sometimes the reason for the breakdown is banal and unpredictable.

I figured out the rear bearing, then go to the front of the fan. Here in the center there is a protective cap.

It turns off, attention. Clockwise, since the thread is left.

Throw it away and remove the propeller from the shaft. You get access to the front handle bearing.

The principle here is the same. First, squeeze out and soften the old grease and dirt with a vaeshka, and then apply a new one.

After that, put the propeller back and close the lid. After completing the repair, turn on the fan at high speeds, and letting it work for several minutes, switch to the speed that is required.

Detailed instructions for repairing the most common faults of the household fan, the best services and the approximate cost of work

In the summer, it is difficult to do without a regular fan. However, extracting the old device and winter leave, you can find that it does not function anymore. There may be various reasons for this. What to do in such a situation? Whether to attribute equipment in expensive repairs? Or try to independently analyze the device with the subsequent elimination of problems? In this article, we will pay special attention to the last option.

How to disassemble the device? Step-by-step instruction

Before proceeding with the performance of the detection of breakdown and its elimination, it is necessary to disassemble the household device. Take this stage very seriously. The fact is that an incorrect independent approach can aggravate the situation and then the device will be completely faulty.

In order to prevent such a development of events, we strongly recommend that you follow the above plan, and then the procedure will become easy and understandable.

  • First, prepare the necessary tools. These are pliers, screwdrivers of different sizes, unnecessary dense fabric. You will need a container with water. But place the fan itself directly next to you.
  • Now, using force, try to remove the protective net. If necessary, use additional tools. Set aside the grid. In front of you you will see three holes of a small diameter. These are latches.
  • Pay your attention to the plastic nut that is available in front of you. You need to unscrew it with a screwdriver. At the same time, you must be counterclockwise movements.
  • Unscrewing the nut, do not use strength, because a fragile plastic may simply not withstand.
  • Look at the engine axis. Be sure to remove the blades from her.
  • Disconnect the grate from the body.
  • Now unscrew absolutely all the screws that you see in front of you.
  • Remove the casing that was attached to the screws.
  • After removing the casing on the fan, only the gearbox and the engine itself remains.

Now that all the necessary phased actions are completed, you can congratulate you, and also, we suggest you go to the next important point.

Repair of the most common faults of household floor and desktop fans: step.By.Step instructions

In this part of the article, we will talk about the most common breakdowns, as well as ways to eliminate them at home.

The device does not turn on

Often, fan owners are faced with the fact that the device simply does not turn on. Some write off this to the fact that the device has not functioned for a long time, and someone sees this in the electric motor.

In order to find a problem and eliminate it, it is necessary to step as step by step by step.

  • First, check the fan cord, which will introduce directly to the electric outlet. To get to it, you need to disassemble the block, which is responsible for switching speeds. Remember that at the time of analysis, the device must be disconnected from the network.
  • Then you need to check the serviceability of the capacitor.
  • Get to all contact wires and various connections. Call them.
  • Next, lubricate all bearings.
  • Check the result by connecting the device to the outlet. If he starts to work, then you have eliminated the problem. Machine oil is ideal for lubrication. Drip a few drops of the products on the bearing under the slope so that the liquid is overlining inward.

Speed ​​switch does not work

Many fans are equipped with a speed switch. However, not all speed switches function as it should be for a long time. This happens as a result of the fact that there is a break in the stator windings. If the winding is torn, then the engine ceases to function. In order to check the integrity of the windings, you need to sharply begin to twist the blades on the direction of the clockwise.

Then abruptly remove your hand from the promoted fan. If after this the speed is sharply turned on, then your winding has burned down. You can purchase windings in any specialized store.

They must be installed in special holes, they are fixed with screws.

Remember that the resistance of your purchased goods should not be zero or very high. Also, we recommend that you do not forget that when installing windings, you must turn off the fan from an electric outlet.

The fan makes a loud noise, buzzes

Sometimes the fan sharply begins to make unpleasant sounds, buzzes and works loudly. This is not normal, because such a household device, as a rule, works quietly enough. It is likely that a loud noise is a harbinger of future problems that it is better to eliminate at the initial stage.

First you need to make sure that a foreign object did not get into the device case.

Also, it is likely that the accumulated dust and dirt scored the sinuses of the fan, as a result of which you can also hear unpleasant noises. In order to make sure of your rightness or vice versa, you need to disassemble the body of the device, as it was indicated in points above.

If necessary, clean the blades thoroughly, and the internal device from dust. However, do not use a large amount of water.

After the procedures done, collect the device back and include in the outlet.

Does not rotate around

The fan not only rotates the blades, but also turns in different directions to cover the largest area. However, sometimes this function loses itself, and the owners are faced with the fact that the fan has stopped performing this option. Most often, the cause of such a breakdown is a burnt stator winding.

Repair of a household fan on the example of Skarlet

If you have broken a household fan, do not rush to carry it for repairs and, moreover, throw it away. In some cases, malfunctions are so simple that they do not require special professional skills to eliminate them.

In such circumstances, the repair of the room fan with your own hands does not take much time, and the savings of funds are significant.

Calling the master at home now in some service services costs at least 300, not to mention work, replacement of details and the cost of the parts themselves in services.

The fan does not rotate. Check the presence of voltage in the outlet with a tester or multimeter. Or you can enable any proper household electrical appliance (iron, charger for a mobile phone and others) to diagnose outlet performance.

Having made sure the power in the outlet, unscrew the box cover with the switching buttons on the fan’s tripod.

Since the fan does not spin when the timer is turned on, and any of the speed buttons (0; 1; 2; 3), it is logical to assume that the voltage is not supplied to the switch or the electric motor is faulty.

See also  Replacing a dual -circuit boiler with a floor

In the box you will see a switch of rotation speeds of the electric motor and a mechanical timer (time relay). One power wire goes directly to the contact of the electric motor, the second through the timer and 4 buttons of the switch to various engine windings. First of all, it is necessary to check the reliability of the contacts of the switch and the integrity of the wires.

This can be done by a multimeter, checking the presence of voltage at the output of the timer. To do this, its switch must be in the “o” position. Then we turn on the speed buttons sequently, checking the voltage at the output of each button.

For safety reasons, it is recommended to check the integrity of the chain with a multimeter, in the dialing mode, without connecting the fan to the network.

In our case, testing shows that there is no circuit through the timer, so the indoor fan does not work due to the malfunction in the contact group of the timer.

Contacts are two copper plates, which are closed by the drive under the pressure of the rotating drive of the timer switch. When counting the set time, the drive enters into the slot on the disk blurring contacts. The absence of an electric circuit can be caused by wear of a drive mechanism that does not compress the plates or oxidized contacts enough.

Methods for eliminating a malfunction

The timer body is transparent, all mechanical gears, the drive and contact position is visible. The complexity of the independent repair of the timer is that it is not recommended to unscrew and open the lid.

The timer gear transmission mechanism has a cocked spring, the axes of the gears are pressed in the nests of the upper cover, which has stop elements. Opening the lid, you will free the spring, the gears will unwind and scatter in different directions. A similar repair of the room fan should be carried out with the skills of an hourly master.

Under domestic conditions, it is easier to carefully drill a hole Ø 5-8 mm above the contacts through which the plates can be bent or the contacts can be bent with tweezers.

The hole for the timer will not affect, then it can be sealed with transparent tape.

After the contact restoration, we turn on the fan and check the work in all modes, with a positive result, collect the structure in the original state.

If the drive mechanisms and the timer contacts cannot be repaired, it can be excluded from the circuit by connecting the wire directly to the input terminal on the “0” й ’button. This is where the fan repair is completed.

The engine from the floor fan. The floor fan does not turn on, what to do

In hot weather, the floor fan is an indispensable device that can create coolness, in the absence. The composition of any fan includes a large number of moving parts subject to wear.

The fan and electric motor are mounted at various ends of the same shaft. There is also a device that provides turns in different directions.

Periodically, various malfunctions arise, and then it is necessary to repair floor fans.

disassemble, desktop

All fans have a typical device, therefore, their malfunctions are also mainly the same.

Deformation of the fan blades

Occurs quite often, since the propeller itself is made of plastic. Blades can be deformed under the influence of high temperatures. As a result of deformation, the blades are touched by the protective net, and there is a characteristic unpleasant noise. Usually deformation is eliminated manually, otherwise, the blades and protection will very quickly become completely unusable.

Deformation of the protective fence

It usually appears as a result of the fall of the floor fan. The fence itself is made of relatively thin metal wire and includes two parts. The front and rear.

The front part is very easy to remove, but with the back you will have to tinker. The propeller is removed from the shaft of the electric motor, after which a large plastic nut is unscrewed and then the fence itself is removed.

After straightening, the protection is collected in the reverse order.

Turning to the sides ceases

The main reason for this may be a disconnected crank. It is necessary to disassemble the body of the device and tighten the mounting screws if they are weakened or unscrewed. In addition, interruptions may occur in turning mode.

To clarify the reason, the gear of the gear of the gearbox is checked, as well as the operation of the switch. If necessary, the gearbox is lubricated with a special lubricant. In the case of severe wear of the part, it is recommended to replace.

In the absence of parts for replacement, the fan can be used in normal mode, without turning on the turns.

The circuit breaker malfunction

Can cause interruptions in work. To check its condition, you need to extract the switch and determine the state of contacts. If necessary, contacts are cleaned with sandpaper.

The fan does not work at all

In this case, you should check the serviceability of the electric motor. If it turns out that the electric motor is defective, then the repair of floor fans, in this case, is economically impractical.

I will not dwell on mechanical malfunctions such as the repair of impeller, body, rotation mechanism, etc. P. To eliminate these breakdowns, it is simply necessary to restore a worn or broken part or replace with a new.

This article will consider issues on the repair of the electrical part of the fan, in which an electric motor with hum, unpleasant smells of the paired or seals are not turned on or works.

For consideration, a more complex model of flooring will be taken. Built-in exhaust fans are much easier, due to the lack of speed switching unit, so it is even easier to repair them.

But repairs, given the price of a simple model of an exhaust fan without bells and whistles, is inappropriate.

In order to find the cause of the fan malfunction, it will be necessary to disassemble it. It will be quite simple and fast to do it with your own hands.First, remove the protective grill, then the blades or impeller of the fan, which is fixed by the nut. Next, it is necessary to remove the second part of the protective lattice and unscrew the lid screws.

Search and elimination of malfunctions during the repair of a household fan

Before proceeding with your own hands, it is necessary to study the scheme of the device. As a rule, an asynchronous electric motor is placed in the floor fan, consisting of eight windings (working and starting). For a successful launch, a phase shift is required by 90 degrees. For these purposes, the capacitor is installed.

The device begins to work after pressing the turning button, after which the indication light lights up and the engine starts, the rotation speed depends on the switch of the windings, for which the switch 3 of the speeds with mechanical locking of the simultaneous turning on several buttons, in which short circuits may occur, is possible.

Before proceeding to check the electric motor:

  • Immediately you need to check the serviceability of the connection cord to the electrical outlet. To do this, you must first disassemble the switch block, and then, in compliance with electrical safety measures, check the presence of 220 volts on the contacts of the light bulb with a multimeter.
  • Check the serviceability of the capacitor according to this instruction.
  • Call integrity and check the reliability of all contacts of wires and connections in the circuit. Barling instructions.
  • If a rumble or noise is heard during the fan, then lubricate the plastic parts inside the gearbox with a lithol or solidol through the holes, which are specifically provided for in it.
  • Check the presence of 220 volts at the output from the switch button on.

Repair of the fan electric motor

Do.It.Yourself repair of the electric motor must start with the lubrication of bearings, very often after that the fan begins to work normally. The shaft of the motor rotates in plastic bushings.

For lubrication, machine oil is suitable- drop a couple of drops of oil of oil under the slope so that it will flow into the inside of the sleeve, and then unit the shaft back and back along the axis until it starts to lightly rotate easily.

disassemble, desktop

The probability of breaking the engine rotor is relatively small and in my practice of repairing household appliances has not yet been found, because the Roth (current) is induced in the rotor under the influence of stator windings.

Often in the electric motors of household fans there is a break in one of the stator windings. If at least one winding is cut off, then the engine will not work at all. To check, quite sharply twist the blades clockwise. Just immediately remove your hand from the blades so that you would not get an injury.
