Fan repair

I already talked about how to choose a floor for a room or an exhaust fan for the kitchen, bathroom or toilet. In the production of cheap models, the manufacturer saves on the quality of materials, so they break more often than more expensive analogues. If the fan has stopped working, then do not rush to throw it away, because to restore its performance in most cases you will not need a lot of time and financial costs.

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.

Elenberg ft-3012 fan. reviews

The fan was bought for a long time in 2007, at the “hump”, on sale, at that time for a small amount. I collected my friend according to the scheme. For all the time of use, I never broke capitally, the only screw flew away with the nut. But this can be easily fixed on your own.

I bought Elenberg fan 10 years ago to work to escape from the heat. The fan is a desktop, then it cost about 300, when buying it did not particularly count on some quality and performance.However, during the first operation, I was surprised that the manufacturer on such a kind of insignificant.

Went as a gift when buying another fan in Eldorado. The action should be called “Help us take out the garbage,” because it was in the trash that I brought this “fan” Elenberg on the same day. The stand is unstable, although heavy.

We bought this fan back in 2007. Then, I remember, there was a hot summer, we then lived in a panel house with windows to the south side, and by noon our apartment was inflamed to maximum temperatures.Then we bought a penny this fan of the dubious company Elenberg.And you know, he is a thousand times already.

We bought this device to work in 2012, the summer turned out to be hot, so I worked every day for 11 hours. A month after the purchase, a mechanism that turns the fan in different directions has broken, made under warranty. After a couple of months, he began to work as a tractor, very rustling, distracting.

Summer in Kherson is hot, stuffy, you can’t survive without a fan. In order not to die from the heat when the old fan breaks, they urgently went in search of a new. The choice in our city of this chassis was small and the husband bought precisely Binatone A-1692.

This year in Astana stood terrible heat. We decided to buy a fan, preferably with good power. We bought a fan in the Sulpak store and never regretted! Took to a one.room apartment. Put in the corridor, perfectly cooled two rooms, hall and kitchen at once. Collected and installed quickly.

I have been using this oil heater for 2.5 years, in winter very often on the round day without stopping. Itself is turned off when heated and turns on when cooling.

This mobile air conditioner saved from the heat for more than one summer. Bought it in 2011, when the heat tortured. They had a shortage in stores and online stores, bought a bo, but it was like a newcomer.Of course, collided with a number of inconvenience.Disadvantages Elenberg PRT-9040: Dimensions and it must be set near.

This Chinese miracle of household appliances is already 10 years old. Did not break, did not burn. He one heated one.room apartment at minus seven, until the central heating is turned on. The advantages of oil units are that they do not burn oxygen in the room. It does not stink. Heating quickly. There is a thermostat.

Cooler’s blades are poorly rotated

In the case when the fan does not pull and poorly drives the air, you will need to disassemble the case in which the motor is located. Sometimes the fact that the propeller does not spin can signal the lubrication insufficiency in the sliding bearing installed in the electric motor.

Dismantling the fan is as follows.

  • First you need to unscrew the protective grid (its front part) and remove it.
  • After the grid, disconnect the propeller. He can be screwed to the shaft of the motor with a nut with left thread. That is, to unscrew the nut, rotate it clockwise, and for its twisting it is counterclockwise.
  • Remove the rear protective net by unscrewing another nut.
  • Unscrew all the fasteners holding the casing of the unit. Sometimes in the handle to adjust the rotation of the case there is another bolt. If it is not unscrewed, it will not work to remove the motor casing.
  • Now, the engine is open, drip a few drops of machine oil (it is better to use spindle oil) on the sleeve (indicated by the red arrow) and turn the shaft several times in different directions so that the lubricant is absorbed inside.
  • After this procedure, a slight rotation of the shaft resumes. Collect the motor body in the reverse order.
  • Turn on the unit and check the air flow strength.

Search for fan faults and ways to eliminate them

To reduce the cost and achieve a low noise level during operation in the fan electric motors, sliding bearings are installed. As a result, after a couple of years of operation, the lubricant is produced, and this is the most common cause of fan breakdowns.

Table of fan faults and recommendations for their repair
External manifestation of a malfunction Possible cause of the malfunction Search for a malfunction Repair method
The ventilator after a while after normal operation turns off and after time it turns on again A self.healing thermal subject is triggered from overheating of windings Check the freedom of rotation of the impeller, disassemble the fan and inspect the stator windings for blackening Lubricate bearings, rewind the winding
The fan turns on, but the blades rotate slowly Lubricant thickened or developed in the bearberry bearings With insufficient lubrication of bearings when working, the fan makes an increased acoustic noise and the smell of burner may appear from the overheating of the winding of the electric motor It is necessary to disassemble the fan and grease the sliding bearings with machine oil
Mechanical wear of the electric motor bearings due to lack of lubrication. In this case, the vibration of the impeller is often observed regarding the center of rotation Shake the impeller relative to the center to the sides. If the backlash is more than 0.5 mm, then the bearing is worn out Replace the bearing new
The fan does not start, the blades do not rotate The cord is not inserted into the outlet Check Insert a cord fork into a socket
No voltage in the outlet Check the presence of voltage in the outlet using a serviceable electrical appliance Connect the fan to a serviceable outlet
The network cord is faulty Check with an external inspection fork and cord for mechanical damage, check the integrity of the cord wires with a multimeter In case of malfunction, replace the network fork or cord
The switch or speed switch is faulty. The battery was discharged in the control panel You need to open the fan and rush the circuit breaker by the multimeter. When the position is turned on, the resistance between the contacts of the switch should be zero In the event of a circuit breaker malfunction, replace it. If not at hand, then you can shorten the contacts of the circuit breaker, and turn off the fan removed the plug out of the outlet
The fan when turned on buzzes and heats up Jammed the rotor shaft due to the production or thickening lubrication Disassemble the fan, rinse the solvent and grease the bearings
The fan when turned on buzzes and heats up Blog of the launch winding or capacitor. Take the impeller with your hand, if you are ovar, then replace the codester or try to find the place of the start of the starting winding
Cliff of the rotor windings Check with an external examination of the winding for the presence of mechanical damage and local darkening, check the integrity of the windings with a multimeter If the winding of the winding could not be found by an external inspection, then it will be necessary to rewind it that it is economically impractical
The heat.guide thermal guide from overheating of the electric motor due to its malfunction worked Check the integrity of the heat.guide by the multimeter. His resistance should be zero. For verification in the absence of the device, its conclusions can be temporarily shabby If thermal guide is found, then replace it with good. If the new thermal.guide again blocks with the short operation of the fan, then the electric motor is faulty

For reliable operation of the fan, it is recommended to disassemble it before each season of operation and lubricate the bearings with machine oil. But no one does it, including me. They usually make grease when the blades stopped rotating or the fan began to make a lot of noise.

How to assemble the bottom of the fan?

There is another type of rack-in the form of a disk, which consists of heavy dark plastic and light white, which are fastened with each other with 4 bolts and nuts.

How to assemble the upper part of the fan?

  • We take out the remaining parts for the upper block out of the box.
  • On the front lattice we fasten with three small bolts of the manufacturer’s label. If this is not done, then this will not affect the fan.
  • We take the back of the fan grill and attach it to the engine compartment. Be sure to make sure that the pins fall into the grooves reserved for them. And then tighten them with a plastic nut. It is twisted very tight, so it will be necessary to make efforts.
  • We put the blades (impeller) on the motor rotor). Be sure to trace so that the groove coincides with the pin of the rotor. The fixing nut is twisted against the course of the clockwise.
  • Put the front grate of the fan and fix it with four mounts located on top, from below and on the sides of the motor unit.
  • Insert the motor block into the pipe and tighten the stop screw at the connection site.

In order not to arise misunderstandings after collecting the fan, check the operation of the motor unit and the completeness is necessary in the store, otherwise you will not be able to completely assemble the entire structure.

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.

Do.it.yourself floor fan repair. All reasons why not spin and how to disassemble.

In the hottest summer days, the only salvation from the exhausting heat, is the usual floor fan.

Not everyone can afford a full.fledged split system or at least a mobile air conditioner.

But unfortunately, this inexpensive and affordable windmill, from time to time breaks. Especially fly like seeds Chinese models.

And there are vast majority in our market. What to do if the fan has stopped rotating and working? What are his main sores and because of which he breaks?

In total, 5 main reasons for the failure of floor fans can be distinguished:

The main problem of cheap models, which for some reason few people pay attention to. Incorrect casting blades. Because of this, an imbalance occurs, bearings are broken, gaps increase.

You can’t influence this in any way, as you already bought a fan with such an initial defect. Sometimes it seems to work, the impeller rotates normally, but does not blow.

Assembling Blakk Stand Fan

That is, there is no cooling air flow from it. Why is it happening?

Due to the wrong corner of the attack of the blades. Its petals are deformed and drive an air flow in a circle, and do not throw it out.

This effect can appear over time, after the fan stood for a long time under the straight rays of the sun and its impeller heated, began to gradually change its shape.

It is treated only by replacing the impeller with a new.

The most common problem is the dried lubrication or its lack. The fan begins to wedge, lose speed and, as a result, the load on the engine increases. Vetrodui no longer works in full force.

The engine wound up with a thin wire of 0.2mm begins to heat up and the windings gradually burn out.

How a similar defect is detected? In this case, the fan ceases to rotate. He is buzzing, but the impeller does not spin.

It also happens that it starts only at 3 speed, and does not react to the first two at all. He just does not have enough power to turn the shaft.

In order to start it, you have to sprout like on old aircraft in an impudent.

By the way, the same symptom may be with damage to the start.up capacitor. How to find out without devices what reason is to blame for the breakdown?

To do this, at least get to the engine shaft, removing the protective casing and blades. If the shaft by hand will rotate with great difficulty, then blame dirt and dried grease.

And if he spins easily and he has inertia, then most likely a conder was covered. Symptom. turned on the fan in the outlet, but it does not spin. At the same time, scroll into a impudent motor and it starts.

If you hold the fan blades when working with your hand, it can stop again. The capacitor is checked by a multimeter if it has an appropriate capacity measurement scale.

To replace, select a new conder according to the same parameters as indicated on the body of the old.

By the way, a dried.up capacitor has not yet been fully affected, also affects the moment. If you notice that they fell from you and the fan began to spin slower, this is a bell to check it.

The problem of tight rotation is solved by a new lubricant of bearings. Here are used, the so.called sliding bearings. Someone calls them bushings.

Apply balls in such designs is expensive, and they thunder over time, they be healthy. For repair it is not at all necessary to disassemble the entire engine entirely. It is enough to unscrew a few cogs and spray to the right places with the universal aerosol WD40.

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.

Typical floor fan device

On the agenda, the repair of the floor fan with your own hands! You should start small: the simplest fans do not have a ground terminal. The device does not have the degree of electrical safety. The device of the floor fan includes a housing made of plastic. Water will get inside. expect a good shake. The floor fan of the specified variety cannot be used near the water. Starting with an aquarium with fish, ending with a flower vase. Particularly dangerous where young children live. The contraption will fall, the child will guess to pour into the milk Draw the conclusions yourself:

When the floor fan falls with a high degree of probability, nothing will happen. We plunge into the design. So far, we will leave the features of the control of the engine speed and button to the side. Let’s talk about the gearbox. Krasnodar floor fan carries one asynchronous condenser engine. The front side of the shaft through the pin, the nut with the left thread is connected to the blades, the back goes to the gearbox formed by two gears, one double.

The shaft is equipped with a thread, clinging, rotating, large wheel teeth. The moment is transmitted to the small wheel that drives the flywheel. The gear of a crooked-shaped mechanism with a diameter in the hand, so rotation is inferior to the speed of the initial shaft of an asynchronous engine.

Through the cardan gear, the crank is hooked by the leg, the engine housing is planted on the axis. When the shaft of the asynchronous engine rotates, the blades move smoothly in one or two. However, you can stop the process. In the double gear, the rolls are attached to the larger gear with two balls with a spring inserted into a through hole. If you pull the regulator handle directly connected to the axis, the latch slides up. The connection between the gear, the shaft, the rotation is stopped. The mechanism implements protection against the fall: six grooves are cut along the internal landing hole of the drive gear. Balls fit. The provisions are six, the mutual transition is accompanied by a click, the axis is turning relative to the gear, the balls beat along the walls, slipping into the grooves.

Clicks are heard, there is a high probability. the floor fan has fallen. The drive jammed, working, clicking, protective mechanism, protecting the motor from combustion.

We believe that the regime is unprofitable to the floor fan, not to turn off the device, the engineer.guard of the motor will certainly break. The gearbox is attached with three bolts to the engine, cut through a pair of lubricants through which you can flavor plastic gears. Concerns the drive, rotating with the speed of the asynchronous engine.

Headache, how to fix the floor fan and collect. We see the alignment: the mutual position of the gearbox, the legs through the transmission, the head of the floor fan will move incorrectly relative to the frontal plane. It can be annoyed. Connection the gearbox, check the product by connecting power. Caution, so as not to hit the current, try to visually determine the correctness of the assembly.

Walking guide for the assembly of the floor fan

There are products from different manufacturers on the market. The installation of models differs in a small way, for this reason it is possible to distinguish its overall scheme. Conventionally, the process of how to assemble the fan can be divided into 3 stages:

This is due to the design features of the product. One of the options is shown on the video on the video. You can start the process with the assembly of the bottom or top. there is no difference.

Ospass floor devices consist of the following elements:

Additionally, models can contain air ionizers, a remote control, but this does not affect their installation.

Installation of the support

Instructions for the assembly of the lower part of the product are reduced to the following actions:

  • the device is unpacked;
  • If the support is made in the form of a cross, then the crossbars are inserted into each other perpendicular;
  • They are connected by the bottom of the vertical riser with the tube inside with four bolts;
  • On the ends of the supports, the plugs are installed, with which the device will in contact with the floor;
  • put forward a telescopic tube and fix it with a plastic nut at a level of the level of height.

Another type of base. disk. is also fastened with bolts and nuts.

Assembly of the upper part of the structure

Next is collected in the following sequence:

  • The rear grid of the casing is fixed on the drive part, seating in the grooves and attracting it with a nut;
  • put a wheel with blades on the axis of the engine exactly along the connector;
  • fix it with a special nut;
  • install and fix the front grate of the casing;
  • They insert the tube into the motor unit and fix it on the rack using a locking screw located at the junction of these parts.

There are options where the seat of the shaft without grooves and then the impeller is fixed with a screw. If the engine is disconnected from the block with the buttons, then with a screw (or a bolt with a nut) they are connected.

The assembly of fans of various manufacturers is identical. You can see this by looking at the following

After all considered manipulations, the device is ready to work. The blades of the assembled fan should easily rotate “by hand”. When turning on, the device should operate without unnecessary noise and extraneous smells (burned rubber), in the modes provided for by the instructions. If this does not happen, then you should contact the store to replace or return the goods. In order not to arise misunderstandings, when buying, it is necessary to immediately deal with the presence of all the required components and performance of the product.
