Do-it-yourself best hood repair

It is difficult to imagine a modern kitchen without a good hood that removes cooking odors and renews the air in the room. Although the device of this device is not particularly complex, sometimes problems may arise with its operation. If you are one of people who, in the event of a breakdown of household appliances, try to find the cause of the malfunction on their own, before contacting specialists, then this article is for you. Below we will look at how to repair kitchen hoods with your own hands when typical problems arise.

The main components of any hood are:

• an exhaust fan with an electric motor;
• speed switching scheme;
• lighting lamps;
• filters.

Standard electrical wiring diagram for a cooker hood

The fan is undoubtedly the heart of this machine. It is he who ensures the movement of air flows through the filter elements, on which fat is retained. Fan rotation in hoods is provided, as a rule, by a multi-speed induction motor.

For your information! The design of a multi-speed AC motor includes a squirrel-cage rotor and a stator with several independent windings. The change in the engine speed is achieved due to the different connection of the stator windings.

Three-speed motor switching circuit: when the switch is in the L position, the rotational speed is minimum, in the H position - the maximum

The fan itself can be of axial or tangential design. From a performance point of view, the latter are preferable to the former because they are able to create a more stable air flow. From the point of view of reliability, the situation is similar - the loss of one blade will practically not affect the performance of the tangential structure, which cannot be said about the axial one. Therefore, the repair of the kitchen hood with the replacement of spare parts for the exhaust fan in tangential models is carried out less often.

Switching speeds in different models can be implemented by:

• buttons;
• slide switch;
• sensor.

The first two options are the simplest. With the help of buttons or a movable lever, the necessary contacts are switched, supplying voltage to the motor windings. It is due to their simplicity that such switches are considered to be quite reliable. All that can happen to them is oxidation or burning of contacts. But even in this case, the repair is not particularly difficult.

More expensive models are equipped with touch control. The panel has additional lighting and looks very stylish. However, the maintainability of the sensor is low. Often it is necessary to completely replace a failed control unit, which costs a lot of money.

Hob lighting is an important part of the cooking process. Modern hoods can be equipped with incandescent lamps, halogen or LED devices, the power and quantity of which depend on the model of the device.

Note! The most economical are LED bulbs. With the same luminous flux, they consume 8-10 times less power than incandescent lamps. In addition, their service life is more than 30,000 hours.

In most cases, the repair of a kitchen hood, in which the backlight lamp has burned out, can be done by any housewife with her own hands. However, there are situations where a more professional approach is required with the use of measuring instruments.

Hob lighting

There are two types of filters that can be used in kitchen hoods: grease and charcoal. The grease filter is installed on all models without exception, since without it, the internal components of the device will very quickly become covered with an oily film, which will subsequently lead to their breakdown. According to the number of applications, such filter elements are divided into disposable and reusable. The first ones are made of acrylic, synthetic winterizer or non-woven fabric and must be replaced every 2-3 months. The latter are made of metal, so their service life is equal to the service life of the hood itself.

Carbon filters are installed in recirculation models and are designed to remove odors. The basis of these elements is activated carbon - a high-quality adsorbent that absorbs all kinds of gases very well. Since the resource of carbon filters is not unlimited, they are subject to periodic replacement, approximately 1 time in 3-4 months.

Metal grease filter

Repairing kitchen hoods at home may be required as a result of various operational problems, the most common of which are:

• decreased productivity;
• lack of lighting;
• lack of any reaction to inclusion;
• malfunction of the speed switch;
• engine breakdown.

Possible reasons: the filter element is clogged, the impeller of the exhaust fan is broken.

Repair: Wash the metal grease filter under water using detergents and / or change the disposable filter. In the event of a fan malfunction (as a rule, one or more blades breaks down), it is necessary to replace it (how to disassemble the hood in the kitchen will be described a little below).

Insufficient performance of the cooker hood is in most cases caused by untimely filter maintenance.

Possible reasons: one of the lighting devices or the lighting switch button is out of order.

Repair: Before you run to the store for a new lamp, you should check its functionality. Incandescent and halogen lamps are checked with a tester (multimeter) in resistance measurement mode. The resistance rating of a thread is usually in the tens of ohms. The absence of readings on the meter indicates a burnt-out filament.

With LED lamps, the situation is somewhat more complicated. Inside such devices, in addition to LEDs, a control driver is installed, which cannot be checked with an ordinary multimeter without disassembling the lamp. In this regard, to test the performance of the LED lamp, it is easier to screw it into the working cartridge.

Important! Before testing a lamp in a different socket, make sure that its rated voltage is 220 V.

If all the lighting fixtures are in good working order, then there is a high probability that the button for turning on the lighting does not work. It can also be checked with a tester - in the pressed state, the resistance between the contacts should be less than 1 Ohm.

Measuring the resistance of an incandescent lamp with a digital multimeter

Possible reasons: lack of mains supply, blown track or fuse.

Repair: In the case when the hood does not respond to any manipulations after it is connected to a 220 V network, first of all, it is necessary to check the voltage in the outlet, for which a multimeter is used in the AC voltage measurement mode.

Note! The use of a voltage indicator allows you to determine only the presence / absence of a phase, while a break in the neutral wire cannot be identified using this device.

If everything is in order with the input power, then the track on the control board or the fuse that is installed in the device in order to protect it from voltage surges may have blown. In this situation, repairing a kitchen hood requires at least some basic knowledge of electrical and electronic engineering.

Checking for the presence of voltage at the outlet

Possible causes: The exhaust fan speed switch is faulty.

Repair: Normal wear and tear is the main cause of failure of a pushbutton or slide switch. In terms of maintainability, the buttons are better, since it is possible to replace one element, and not the entire block. If the slide switch began to "junk", then you can try to disassemble it and clean the contacts. However, so that the problem does not return soon, it is more advisable to replace the old switch with a new one.

To replace the button, it is enough to be able to work with a soldering iron

Possible reasons: thermal fuse blown, starting capacitor faulty, motor winding burned out, rotor wedge.

Repair: It is possible to determine the exact cause of engine breakdown by indirect symptoms. If, when turning on any speed, the unit does not make any sound, and there is also no smell of a burnt winding, most likely the thermal fuse has blown.

Note! The thermal fuse is installed directly in the motor housing and burns out due to strong overheating of the windings.

In the event of a "hum" of the engine when power is supplied to it, two options are possible: a malfunction of the starting capacitor or a wedge of the rotor due to poor operation of the grease filter. Well, it's a very bad situation if there is a smell of burning insulation. Only rewinding the engine or buying a new unit will help here.

Asynchronous motor for kitchen hood operation

To repair the hood with your own hands, you need to know how to disassemble it. By following the instructions below, you should not have serious difficulties with this process.

1. Remove the grease filter located at the bottom of the device.

1. We unscrew the protective panel (if any).

1. We disconnect the panel with lighting lamps, having previously disconnected the power connectors.

1. Next, remove the control board.

This instruction is an example of disassembling a modern cooker hood in a kitchen. It should be noted that in many models, individual blocks are attached independently of each other. For example, to remove the engine, it is not necessary to unscrew the backlight unit.

Advice! If disassembly requires disconnecting connectors or wires, be sure to mark or photograph the items before handling. Thanks to this approach, you will not have any difficulties with connecting blocks during assembly.

In order not to resort to repairing the kitchen hood, you should adhere to the rules for operating this equipment, which are established by the manufacturer. Let's highlight the main points:

If a gas stove is used in the kitchen, the hood should be installed at a height of 70-80 cm from the hob, if an electric one - at a height of 60-70 cm. If the hood is located below this mark, overheating of structural elements with subsequent deformation is possible. At the same time, a higher position will reduce the efficiency of the device.

If there is a manual speed switch, it is advisable to start starting from the lowest stage. Setting the maximum speed immediately will lead to an increase in the load on the electric motor, which can reduce its service life.

Failure to clean or replace the filter elements leads to the fact that grease particles begin to penetrate into the device, covering the engine, control board and backlight with an oil film. In addition, practically no air passes through the clogged filter, so the efficiency of such a hood is zero.

• Overvoltage protection.

Like any other electrical appliance, the cooker hood must be protected from power surges. Of course, a fuse is usually installed inside the device, but this may not always protect the equipment from unstable network. It is better to cope with this additional installation of a protective relay, which instantly cuts off the power when the voltage deviates too much from the norm.

Voltage relay - additional protection of equipment against power surges

The difficulty of repairing a kitchen hood depends on the nature of the problem. Anyone can change a burned-out light bulb, but serious difficulties may arise with the restoration of the fan operation. If there is no experience in repairing electrical appliances at all, then it is more advisable to contact specialists so that you do not have to buy new equipment.

The preparation of everyday meals and culinary delights is often accompanied by different smells, and they are sometimes not very pleasant, especially if they spread.

The ventilation ducts in our homes, unfortunately, do not always cope with polluted air and odors. This was the reason for the development of various.

For most people, the kitchen has long ceased to be a utility room where food is prepared, food is cleaned, and dishes are washed. The family often gathers here.

Hood Cata wiring diagram. Failure of a cooker hood mainly occurs due to overheating of the electric motor.

There are a number of other reasons, but the more common one is an electric motor problem.

The reason for the overheating of the electric motor is the filter grids clogged with fat deposits.

The filter grilles must be clean so that the intake air flow can circulate without obstruction.

Fat deposits, accumulating in the cells of the filter grids, block access to air flows, reducing the amount of intake air and the quality of the blowing of the electric motor.

Consequently, the efficiency of the hood is significantly reduced, and the heating of the electric motor increases.

Overheating of the electric motor leads to a turn-to-turn circuit in the windings of the electric motor, which entails the failure of the electric motor.

In other words, the cooker hood becomes unusable.

Repair of a kitchen hood, in the event of a failure of the electric motor, is the replacement of the electric motor with a new one.

EXTRACTOR CATA ELECTRICAL DIAGRAM.

The color of the wires in the diagram (Fig. 1) is completely identical to the color of the wires of the TA, TA-P motor.

The capacity of the starting capacitor is 5.5 mf. Below is a table of resistances between different pairs of motor wires (motor).

If suddenly something is wrong with your cooker hood (the efficiency of its operation has decreased, there are extraneous noises, the engine speed does not change), it makes sense to check the parameters of the electric motor.

It is possible that there is an interturn short circuit. Perhaps the copper-graphite bushings have become unusable.

Perhaps the starting capacitor has lost its capacity, or the buttons for switching the speed of rotation of the electric motor are out of order.

Pay more attention to the cleanliness of the filters (grilles).

Lattices clogged with fat deposits, as mentioned earlier, will lead to rapid wear and tear and damage to the electric motor of your kitchen hood.

If your cooker hood is electronically controlled, I highly recommend protecting it from power surges and surges.

In the event of a hood failure or a violation of its normal operation, as a rule, specialists are involved to search for the malfunction that has arisen. Why pay money if you can find faults yourself and easily fix it? In this article, we will consider the main malfunctions of kitchen hoods, as well as provide recommendations that will help you eliminate them.

It's one thing if your cooker hood is already a dozen years old and has been weakly drawing air lately. Here it is already possible not to think about repairs, it is easier to buy new equipment. But what if the purchase has not served you for a year, and the fan is no longer able to cope or is completely out of order? The first step is to find out the cause of the malfunction, and then fix it on your own. The main "culprits" of breakdowns can be:

All these reasons can lead to failure and further repairs, so take into account all the points for the future so that this situation does not arise again!

Now we will proceed as follows: we will list all existing faults in turn and provide instructions on how to repair a hood in the kitchen with our own hands under each one. Breakdowns will be listed from most common to least likely to occur and harder to repair at home.

Very often, the exhaust panel is used to illuminate the work area in the kitchen. This is really convenient and is a competent approach, because in modern technology, powerful LED lamps or halogens are installed.

If your lighting does not work, you must take the following repair measures:

1. Check the light bulb itself, it may have burned out.
2. Turn on the fan to see if it works. If the blades are not spinning either, we will talk about how to repair the system a little below. The engine is running - we are looking for the malfunction further.
3. Check the voltage at the outlet with an indicator screwdriver. Immediately look at the switchboard, possibly knocked out a machine gun. Is the outlet working properly? If so, you need to check the integrity of the electrical cord, then ring the backlight switch and the rest of the circuit with a multimeter. Thus, by elimination, you will find the cause of the malfunction and you will be able to proceed to repairing the hood in the kitchen with your own hands. Usually, hands do not reach this point, tk. most often the light bulb burns out or the socket fails.

The second most popular malfunction of a kitchen hood is that the fan does not pull out well. Not sure what to do in this case? Things are easier here. First of all, check if the filters and grease trap are dirty. Most often, these two components are responsible for the fact that the hood does not draw air into ventilation or does not ventilate well.

In order to repair the hood with your own hands, you need to clean the filters and re-enable. You can see how to properly clean in this video lesson:

Another possible situation is the occurrence of a vacuum in a room with closed windows. As a result, the hood will pull weakly or stop drawing air at all. In this case, the repair consists in the fact that you yourself need to open the vents and ventilate the kitchen in a natural way.

Another reason that the hood pulls poorly is the lack of draft in the ventilation duct of the house. In this case, you can check the presence of traction with an ordinary lighter - light a fire and bring it to the ventilation hole in the wall, as shown in the photo. If the flame does not suck into the ventilation hole, it will be necessary to make forced ventilation, which we will talk about below.

If nothing happens when you turn on the button on the panel, it will be much more difficult to repair the hood in the kitchen yourself. This is exactly the case that we talked about above - and the fan does not turn and the light does not turn on. First you need, again, to check the electrical cord, the voltage at the outlet and the machine in the dashboard.If everything works, take a multimeter in your hands and go to the "continuity" of the circuit. First of all, you need to test the switch on the panel, perhaps one of the contacts has burned out (usually the first one). Then look at the diagram where the fuse is located, which burns out at least often.

Is the fuse in working order? Check the capacitor, if its resistance is normal and does not seem to swell, most likely the engine does not work. We talked about how to check a capacitor in a separate article. The motor windings need to ring and if the malfunction lies in an open circuit in the motor area, it is better to throw it out and buy a new one, because it will be very difficult and impractical to repair the part.

If the cooker hood hums when it is turned on, it may be due to poor manufacturing quality. A lot of negative reviews about the increased noise level can be found on the Internet. The answer to the question why the system is noisy is quite simple - poor-quality assembly of the product, which in this case cannot be repaired by hand. For example, at such firms as Cata, Kronasteel and Elikor, the rumble during operation is practically inaudible even at maximum speed. We recommend that you immediately familiarize yourself with how to choose the right range hood for your home in order to know the names of the best manufacturers of kitchen appliances!

If you are sure of the quality of the selected product and you probably know that the fault is in something else, we recommend that you check the quality of the fixing of the case to the wall / kitchen set. Even a small vibration gap can cause knocking, rustling, ringing. To prevent the equipment from making noise, it is necessary to do the following - tighten all the fasteners or put a piece of foam rubber in the problem area, which will eliminate the knocking.

If the engine hums but won't start, the most likely cause of the problem is the fuse. Do-it-yourself hood repair in this case is quite simple - you need to replace the fuse with a new one.

Everything is obvious here - the button in the control unit does not function. You must remove the protective shield and visually inspect the button as maybe the contact just burned out. After that, look at the tracks on the board and ring the circuit with a multimeter.

In addition, the cause of the malfunction may be the starting capacitor, which is burned out. In this case, repairing the hood with your own hands is quite simple - you just need to replace the capacitor yourself.
