Floor fan does not spin but just buzzes

The blades of the cooler do not rotate properly

In the case where the fan does not pull and poor air flow, you will need to disassemble the housing, which houses the motor. Sometimes the fact that the propeller does not spin can indicate a lack of lubrication in the plain bearing installed in the electric motor.

Floor fan fix

To disassemble the fan, proceed as follows.

  • First you need to unscrew the protective grid (its front part) and remove it.
  • After the grid, disconnect the propeller. It can be screwed to the shaft of the motor with a nut with a left-hand thread. That is, to unscrew the nut, turn it clockwise, and to tighten it, turn it counterclockwise.
  • Remove the rear safety net by unscrewing another nut.
  • Unscrew all fasteners that hold the casing of the unit. Sometimes there is another bolt in the handle to adjust the rotation of the housing. If you do not unscrew it, you can not remove the cover of the motor.
  • Now with the motor open, it is necessary to drop some drops of machine oil (it is better to use hemp oil) on the hub (marked with a red arrow) and turn the shaft a few times in different directions so that the grease is absorbed inside.
  • After this procedure, a slight rotation of the shaft will resume. Reassemble the motor case in the reverse order.
  • Turn the unit on and check the airflow.

Repair of floor and table fans with your own hands

After detecting the problem with the fan, you can proceed directly to the repair. First prepare the necessary tools and materials depending on the type of fault. The first thing to check after diagnosing the cord, plug and socket is the serviceability of the electric motor. Often the problem is in the chip, so first determine the level of current flow to the board and the output from the chip. If there is no voltage, the problem is in the breakage of a microcircuit which can be replaced.

If the chip is energized, but the floor fan or table fan does not turn on, you will have to take apart the case and check whether the current flows inside. If not, the problem is in the motor, so you have to give the motor for repair.

  • disconnect the two wires connecting the electric plug and the circuit board;
  • Do the same with the 2 wires from the board to the motor;
  • connect a new microcircuit.

To understand how to do the repair of the fan yourself, you need to know the principle of operation of the device. Schematic:

  • motor of asynchronous type, installed on standard floor and table fans, has 8 starting and working windings;
  • To start, the phase is shifted by 90 degrees with the help of a capacitor;
  • start-up is carried out after the push-button is pressed (first the red light turns on, then the electric motor starts rotating);
  • The speed of torque is affected by the 3-speed switch, which has mechanical interlocks for simultaneous switching of speeds.

Rotor Replacement

the rotor is usually located on a gasket under the cover or behind the shaft, so to repair or replace it, remove the motor with screwdrivers. The first thing to do is to inspect the wiring, which may be the cause of the malfunction. If it does not have any defects, you will have to replace the rotor, as it is not possible to repair it yourself. Be sure to write down the number of the device and buy the exact same model.

  • Carefully disconnect the wire leading to the rotor;
  • Unscrew the screws;
  • remove the fixture;
  • fit the new rotor, screwing it firmly to the base.

How to repair the control box?

Control unit is broken because of the worm gear. You can fix the problem yourself by following the instructions:

  • Remove the terminal board (you do not need to remove the motor for this purpose);
  • if there are gaskets for the control box, remove them;
  • unscrew the shaft with a screwdriver;
  • remove the control box;
  • Remove the cover on the back, giving access to the worm gear;
  • to check the operability use a tester (without breakage the resistance parameters must not exceed 50 ohms)
  • in case of a malfunction, replace the old element with the new one.

What to do if the flange is broken?

Floor and table fans use plastic flanges, which are easy to break, especially if the unit is dropped. Therefore replacement is required. How to do it:

  • Unscrew the back cover near the motor or shaft depending on the model;
  • remove the crank;
  • Disconnect the worm gear without removing the control box;
  • remove the switch;
  • screws off the flange and disconnect it;
  • install the new flange in reverse order.

Diffuser repair

The diffuser is in the control box. Twisting of the regulator is the cause of its breakage. Replace it as follows:

  • remove the top cover without touching the motor;
  • undo the center flange;
  • Remove the control box;
  • Remove the diffuser from the back (pry the base off with a screwdriver or knife);
  • Replace with a new element.

Cooler Repair

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

  • If the normal deformation of the impeller on the background of overheating, you must remove the propeller, slightly warm the blades and align so that they do not touch the protective grid 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, the debris can be glued with a reliable glue.

How to Repair a Condenser?

The capacitor usually breaks because of sudden voltage fluctuations in the electrical supply. It is located behind the center flange. The cause of the malfunction is a lack of phase shift or no power to the winding. The main sign is no rotation. Capacitor failure can be checked with a multimeter (measuring mode. resistance).

Before measuring, discharge the instrument to its minimum (simply short-circuit the leads). After making contact with the probes, watch the readings:

When buying a new unit, pay attention to the voltage and capacitance of both capacitors. they should be equal. How to replace:

floor, does, spin, just, buzzes
  • Remove the electric motor from the housing;
  • Disassemble the power supply;
  • if the crank is in the way, remove it and the flange (depending on the model);
  • Disconnect the capacitor and install a new one.

How to Repair a Speed Switch?

If the speeds do not switch, look for the problem directly in the switch. To do this, proceed as follows

the most common causes and how to fix them

Bearings

Household fans have sleeve bearings mounted on the rotating shaft with bushings. It is not possible to remove these fixtures as they are pressed into the housing at the factory. There are no spare parts available separately, so the whole unit must be replaced. To avoid this, often drop machine oil into the bearings.

The point is that during “dry” operation there is a gap between the bearing part and the shaft, which causes axial run-out, reduces the number of revolutions and accelerates the wear of parts. Bearings also get dirty, so be sure to clean them before lubricating them.

Crank

Crank may become deformed or pop out. In the second case, the culprit is the shaft. To get rid of the problem, do the following:

If stainless cranks are deformed, use a vise to straighten them or take the part to a workshop.

Bulbs and pushbuttons

If indicator light does not come on, it is burned out. Therefore, it must be replaced with a new one by disassembling the construction. But it also happens that the light is red, but the fan doesn’t work. In this case, the culprit is the pushbutton unit. the buttons don’t work. Their operation is quite simple. the transition from “on” to “off” position.

To check the functionality use a tester, which checks the input and output of the pushbutton unit. If one of the switches is broken, you will have to replace the entire unit.

Fan does not turn sideways

About the causes of such a breakdown is described above, but troubleshoot as follows:

  • If the fasteners on the crank are loose, disassemble the motor housing by removing the cover from the back. Next, under the gearbox check the degree of connection between the gear wheel and the crank. Secure with tools if necessary.
  • If the gears do not work properly, the gearbox will have to be disassembled and the gearwheel removed. It may be clinging due to wear or lack of lubrication. If worn, replace the part.
  • If the elements are dry, oil all moving parts.

Problems due to unbalanced impeller

After repairing a floor or table fan, the propeller must be properly installed. Otherwise, the blades will not spin normally. Usually a simplified method. static balancing. is used. How to do it:

  • put the fan into operation;
  • set initial rotation manually;
  • mark the upper point of the blades with a pencil;
  • Make a few rotations.

This manipulation allows you to detect imbalance. If the impeller does not return to its starting point, lubricate the bearings; if the points are the same, make a counterweight. For this purpose any improvised materials. nuts, screws, wire, etc are used. д. To fix the weight to the propeller use duct tape, scotch tape, glue. To lose a constant point of overweight, the weight is mounted to the same point, but on the inner side of the blade.

I was too lazy to write this material in the summer, but nevertheless it is useful for the next “shitty winter” ))) Despite the fact. That summer is over, but the long heat that got us sick in every way will stay in the minds of many for a long time to come. I’ve written several recipes I’ve used to save myself from the heat. But the most popular remedy that occupied all the top of hit parades of hardware and household appliance stores was the fan and air conditioner. When we got closer to God for a couple of months we all rushed to buy fans and this mass of plastic buzzing blades was blowing our sweaty bodies all day long. Some people were more lucky and had not one but two fans which of course was the envy of those who could only see the price tag on the empty counter. But one way or another, any mechanical equipment sooner or later breaks down, which includes both desktop and floor “rotisserie. Fans broke most often in hot weather when they were working tirelessly for 25 hours a day. Many people are simply stupidly threw their rescuers in the trash or put in the hallway for the simple reason of “when you plug in the fan does not spin or spins very slowly, making a buzzing sound and emitting a smell”. I also faced this problem when my fan stopped. Since fans are in short supply in stores and you want airflow all the time, I started to fix the fan and at the same time decided to get to the bottom of the problem of fan failure.In spite of the fact that fans can be floor-standing and desk-mounted, the difference in construction between them is no more than between a fork and a spoon. So whoever understands how I disassembled my floor fan, will probably understand how to disassemble the table fan.So, move closer to the monitor, Uncle Chinilkin starts his instruction. Take the fan and put it near you and put a screwdriver, pliers, cotton rag and oil can. If you do not know how to use these things, then invite your dad or mom to the monitor.Remove the protective mesh from the fan. by opening the three latches.Unscrew the plastic nut counterclockwise. When you wrap it back up, don’t use too much force so you don’t break it. You can’t buy a spare anywhere!Now easily remove the impeller from the motor axle. Again, be careful because the plastic the impeller is made of shrinks and crumbles over time. You’ll break the seat. You’ll be fiddling with duct tape, winding it around where it sits on the shaft to at least restore some sort of rotation transmission.After removing the impeller, unscrew the plastic sprocket nut which secures the rear grille to the housing.Now unscrew all the screws from the front of the case. Sometimes screws don’t come out well, but don’t use your screwdriver too hard or you’ll break the thread in the plastic.Unscrew the screw from the rear side of the casing which fastens the casing cover.Now that the cover is off you can see that the main part of your gearbox consists of two things: the motor itself, made of metal fortunately, and the swivel gear, made of plastic. This gearbox consists of a worm gear and a sprocket that turns your fan left and right when you run it. There is a condenser attached to the gear box on a small screw that is needed to start the fan motor.Fasten the 3 screws (or screws). (This is the way it is with the motor), which fasten the gearbox flange to the motor and carefully remove the plastic stuffing of the gearbox. In the photo you can see the back shank of the shaft with the worm that the gear mechanism engages with. By the way, if you are interested, you can take another 3 screws of the gearbox and look inside and find out that the mechanism is fully plastic and greased with grease.Now it is time to remove the four screws that connect the two halves of the motor housing to the stator. Put the screws and screws in a jar so you don’t have to look for them under the table or under the couch.Slowly pull off the back wall of the motor, if necessary, twisting it along the axis of the motor.Do the same with the front cover. note that there is also a rubber gasket on the shaft that must be preserved. But for now you need to pull it off the shaft and put it in the same jar.Take the covers in your hands and first remove all the dirt in the bearing assembly with a rag. You can wrap a rag around the thin rod to make it easier to drive the rag through the hole. After degreasing everything with acetone or gasoline. again wipe dry and drip grease from the grease nipple into the bearing (holes in the center of the cover). Use only liquid grease! No lithol, solidol, etc.д.! The grease will get caked on the shaft in a couple of days of continuous use in the heat and you’ll be back to disassembling your cooler.Now for the most important thing, the cause of the motor jamming. The main cause of the fans jamming, i.e.е. the main cause of the failure is the very thick grease in the gearbox and on the rear shank motor shaft. During operation, the lubricant is carried along the shaft into the bearing and there is a sludge build-up, which over time becomes larger and clogs the motor. It is necessary to wipe off all grease from the shaft shank and in the gearbox itself on the part that will be caught in the shaft! Be sure to! There is no point in greasing a plastic gearbox until they make it out of metal.Assemble everything back in reverse order as the Chinese did before you.If the picture is too small, click on it and see a bigger picture.

The floor fan stopped spinning, how to fix?

It doesn’t spin because the coils are torn. Brought a couple with the same diagnosis. It turned out that the rotor rubbed the outer coils of the stator coils.

Doesn’t spin, and yet humming, in both caps with the axle rotates easily, but in the winding itself when the shaft is in, it rotates a little tight. Tell me how to properly wire the coils ?

You inspect them carefully where the rotor is close. You’ll see some torn coils. It’s high time to throw it away and buy a new fan. Repair is more expensive than the cost of a new one.

You can also put the motor from another fan, in which it is not the motor that is defective, but something else.It is even possible to “fit” another type of engine, suitable in parameters.

I’m reading this and I’m FUCKING. the price of such a screw in our country. 5-7 у.The price of the engine at the flea market for it. 1 buck. but here. And a 4 page brainspace.

5.7 у.I don’t think it’s a floor fan, I think it’s a table fan. Floor. It’s 20 minimum, and not everywhere, and even more in summer. I never saw any motors separately, maybe I didn’t look hard enough. And Mastak once said: “Well, you bought an electronic clock, and what did you learn??”.

I understand that the author has already sounded the winding and it is time to take a mallet and center the shaft light blows on 3-4 sides perpendicular to the axis of the bushing selffcentered rarely but when the generator contact the stator in the pole area due to deformation or marriage-defect found by coating lightly drying thin paint and give to spin, where it touches we will see but if it touches the winding (improper installation or assembly) then oh! possibly to the morgue. although as luck would have it

musor. at this point you have read my mind and answered almost all my questions Sorry, but as sampa said, that’s how you get a wire break http://i080.radikal.ru/1207/53/ae1af4c1c538.jpgThe breakage is only at one point if you solder the ends together? or twisted together?

THEDOGG: Breakage in one place only if you solder the ends? or twist together?

Hn. so what’s wrong with soldering (with passive flux. at least clean rosin.).You can, of course, and twisting without soldering, it’s so-called cold soldering (used in connection with. lapacha.cables. etc.)(But the vibration can shatter.loosen the contact)Put duct tape between the main coils and the damaged core.(temperature-resistant. cloth.)And then.soak in oil varnish.If it was a single break, it will turn.Go ahead

The fan doesn’t work anymore. What to do?

Hello, everybody! In this article I will tell you what to do if you, suddenly, stopped working fan. Don’t hurry to throw it away and run to the store to buy a new one. Maybe it’s too early to retire the old air blower and it can be resuscitated! How to prolong the life of the fan?! Read more!

My wife and I thought that our sales clerk would be very uncomfortable without a fan. It’s time to put it back. Brought it to you. Let’s turn it on and it won’t turn on.

Electric fan repair || Motor humming sound || Rotor not rotating || Bushing repair

It just won’t turn on, that’s all! You though plug it in, though press buttons, sing songs to it, coax it. ♪ no way ♪! The propeller won’t turn. We even brought a second fan to take the first home and there to try to fix it. But then we decided to fix it right in the store! I’ll write an article about it, too!

Why the fan doesn’t turn on?!

And here’s a little secret. If the fan propeller does not spin, it does not mean that the fan has given up its life and it must be parted with. No way!

The thing is, as it turns out, almost all such fans have one big problem. Most common.

The motor, which is responsible for spinning the propeller, dries up from time to time. Yes, yes, it lacks grease, which makes it unable to do its job. turn the metal pin. Therefore, you need to help the motor, and properly lubricate it with machine (or any technical) oil!

To do this, you need to disassemble the fan.

What tools do you need to disassemble the fan

In order to disassemble your old friend. of an air blower, you’ll need the following tools:

Phillips screwdriver (take some Phillips bits with it)

A knife (to pry one of the little white plugs).

How to disassemble the fan: step by step instructions

First remove the rim by unscrewing the first screw (above). In some versions of the fan, it may not be. It might just be the latches.

Then remove the fan blade (you don’t need a screwdriver for this).

Unscrew the retaining nut and remove the fan guard frame.

Then you will see 4 screws that you should unscrew.

Then unscrew the top fan position lock. There’s a small screw inside.

Use a knife to pry open the white stopper that’s on the back of the fan.

And unscrew the Phillips screw that you find there.

You’ll be holding this very interesting contraption in your hands.

By the way, when I disassembled the fan, unknowingly, I also unscrewed the lower screw of the holder, thinking that if I don’t do this, I will not remove the top cover.

Yeah, yeah, the cockerel was shocked, too! You can see its eyes?!

In general, you didn’t need to unscrew this screw. The cover would have come off anyway. And here’s how to screw it back in. It’s not such an easy thing to do. I thought if I didn’t do that, I wouldn’t be able to get the top cover off.

Well, and now, generously drip machine oil into the motor. There is a black hole in the picture where you can see the spring.)

We used a spray oil we found at home. Any technical oil will do.

As you lubricate the motor as you twist the iron pin, letting the oil properly lubricate the insides. It should turn more easily. And by a lot!

Then you assemble the fan in the reverse order, plug it in, press the power button and voila! It’s spinning!

If the above method does not help, I also recommend checking the wires coming from the head of the fan. They are often kinked, frayed. Well, if this does not help, you will have to send it to a well-deserved rest.

How to repair stand fan or table fan (fan won’t Spin or Rotate) Step by Step instructions

Why the fan buzzes but does not spin?

Your little helper begins to hum and emit an unpleasant odor when you turn it on? Another frequent fan breakage is the blades that do not spin. Why does this happen when only yesterday the appliance was working properly? Unfortunately, this is a problem faced by many users, especially when actively using the device. Today we will examine why the fan hums, but does not spin?

If the floor fan does not turn on and the external inspection did not yield results, you will have to unscrew the device. For this, prepare a screwdriver and pliers beforehand. By the way, this method is suitable for those who are concerned about the question why the floor fan slowly unwinds. Reanimation of the device is carried out in a few steps:

Remove the grill that covers the fan blades. As a rule, the grid is fixed with three pawls.

Next, we remove the impeller. It is fixed with a plastic nut. It should be unscrewed. Act carefully so as not to damage parts. Otherwise you will have to invent an alternative to the nut. By the way, also carefully remove the impeller. Plastic parts of inexpensive fans quickly wear out under the influence of heat and air. As a result, the impeller can crumble right in your hands.

Now we need to disassemble the housing. First you remove the nut that secures the rear grille. Then gradually remove the screws, first from the front and then from the back of the fan.

When you get to the hood of the appliance you can take it off. You’ll have the motor and gearbox in front of you. The last part is made of plastic. The condenser is attached to it. It’s necessary for starting the motor.

The next step is to remove the gearbox. It’s fastened with a few screws. After unscrewing them you can easily remove the gearbox with all the stuffing.

Then we remove the screws that connect the motor housing with the stator. Now we can remove the front and the back of the box. You’ll find rubber bands as you go, put them in a separate container. There you can also put small screws.

Now proceed to clean the bearing itself and the surface around it. Remove the dirt with an ordinary cloth. Then you should degrease the surface, acetone will do, and wipe everything dry. In the center of the bearing you need a drop of oil.

In this way you remove the thick grease that gets inside the motor. As a result, it seizes up and the fan blades stop spinning. The process described can be repeated for a tabletop unit, because they are designed the same way.

An easy way to spot an air conditioner malfunction

If you got to this page it means that you have faced with problem with air conditioner malfunction. Today I will tell you about the most widespread breakages of split-systems. But before we start looking at them, you should understand that there are complex systems and special cases where you have to deal with them on site.

Some signs of breakdowns can have ambiguous solutions. To cover the whole volume of problems, of course, one page is not enough. But still I will try to set out the main faults so that you learn to think in the right direction and look for ways to solve the problem.

I think it will be right to start this article by listing the symptoms of malfunctioning. After all, when you first encounter such a problem, you see only its external manifestations. I would even specify that for the user the main indicator is first of all the “behavior” of an indoor unit. That’s why in this article we’ll limit ourselves to studying the problems, focusing on the behavior of the internal unit.

After we will understand with external signs let’s enumerate the reasons of their appearance and ways of their elimination. Since now our main task is to detect malfunction and start searching for its cause. And the elimination of each individual cause is a topic for a separate article.

Possible breakdowns of Timberk fans

Timberk company fans have recommended themselves as inexpensive and easy-to-use devices, for creating comfortable climatic conditions, maintaining the air exchange in the apartment or office. Despite the good quality they are prone to breakdowns.

The following malfunctions have been noticed by customers during operation:

  • The air blowing power decreases because of the soft plastic of the blades;
  • There are cases when the condenser fails;
  • appearance of unusual noises during operation;
  • electric motor breakage;
  • The rotor breaks;
  • there is a strong backlash;
  • There is a smell of burning oil during prolonged operation;
  • The feet bend and change their geometry under the weight of the motor;
  • Overheating of power unit;
  • mechanical breakage in the fastening points.

Timberk products are leaders in their segment in terms of price-quality ratio. All devices have a manufacturer’s warranty and can be replaced upon request.

The main “noise maker” is the wind. When entering the ventilation system, the wind meets the air flow, turns around and creates an audible vibration. Also, the cause of sounds can be a human factor: a specialist who installed the fan could not fasten or poorly fasten some parts of the device or just buy a very noisy model.

Noise is often caused by errors in the installation of the ventilation system:

  • mistakes in ventilation system design: wrong choice of ventilation unit, narrowed duct section;
  • Incorrect installation: the fan is not secured, some part of the fan is not properly placed;
  • Poor quality materials;
  • Powerful models are noisier, and the model designed for a large room just runs too loud.

If the fan was working properly, and then suddenly began to make noise, it is likely that the wear and tear of the fan parts. If the worn-out part can not be repaired or it is impractical, you can buy an exhaust fan in Ukraine in our store.
