It is quite possible that the exhaust is not included equipment or for some reason loses its effectiveness. Do not immediately rush to the phone and call a specialist. After checking the equipment may be that the repair of kitchen hoods with their own hands the best way to resolve the problem.
Properly installed, the new extraction equipment from well-known brand will pull air regularly, ensuring its maximum cleaning and demonstrating a minimum of noise. However, even such a machine can "buck" and stop working as it should, under certain conditions:
- the room will be a fair share of steam and odors;
- some functions of the device will not be available;
- the device will cease to be included.
Causes of failure
Not always these problems can be the result of a serious fault, the removal of which requires special knowledge. If any are found you should always start with the simplest of solutions. According to this rule in a situation where the unit refuses to be turned on or can not cope with cleaning the air, the most probable are the most obvious reasons for this:
- lack of electricity in the network;
- clogging of filters;
- lack of traction in the ventilation duct of the building;
- burnt light bulbs in the absence of built-in lighting.
The device does not turn on
If the device does not start when connected to the network and the respective switch position, the first candidate for the scan is the voltage at the outlet. To test using a multimeter or other household appliance. Just have to test the machine on the panel. Just be sure that the voltage is OK, you can sin on the internal device malfunction. Available to address at home may be the switch contacts, fuses, capacitors. Besides the lack of resistance, their signs fault traces are burning, melting, swelling in the case of the capacitor.
Failure of the motor
Circuit Testing may continue until the electric motor. When all the previous items of electrical equipment operable likely break occurs within the engine braid. In this case, we recommend replacement parts for the same. To reinstall the motor must be independent:
- turn off the power;
- remove filters;
- remove the outer panel, and disconnect cords;
- Unscrew the screws and remove the hood;
- free mounting of the motor and the wire on terminal connections;
- perform replacement and return everything in place in reverse order.
Failure of the motor - not frequent breakdowns, especially of reliable, branded devices. For example, the Spanish Cata or Slovenian Gorenje likely not deliver such problems.
clogged filters
Experienced users will be greeted by an abundance of smells decrease in operating efficiency exhaust equipment. Kitchen quickly filled with the smells, which, when normally the first work are felt only in the area of the plate. The most likely cause of such discomfort is untimely care of filters. Their treatment should correct the situation.
Washing and cleaning of the filter elements should be carried out in accordance with the manufacturer's recommendations, which are set out in the instructions for each specific model. In the presence of disposable inserts need to be replaced for the same.
The absence of traction
The flow-through version of the cleaning problem may be a loss of traction in the ventilation shaft. Check its presence can be old-fashioned way: holding a candle, match or lighter in the ventilation grille. When the flame does not go out and does not vibrate, likely channel blockage. If this happened in an apartment building after the installation of the equipment will have to apply to the management company or the relevant services. When a problem is detected before the installation will need to find an alternative, likely with air output of the window. When thrust in the trunk is, and extractor fan still does not pull, errors are possible with the laying of duct flutes, rarely made of PVC plastic.
Problems with integrated lighting
Modern extraction of all types are equipped with built-in lighting elements. This may be used LEDs, halogen bulbs, rarely, in the most low-end models of incandescent lamps. When the backlight is not working, the cooking area is not illuminated. It is not critical, but it creates unnecessary problems. If there is power in the network and the correct operation of the engine the cause of this failure is likely to be blown bulb or no contact on the switch elsewhere in the chain. The specific reason continuity is established through the circuit, reduction of the contact, in the most simple embodiment - by replacing the lamp.
It does not work gear shifting
Even low-end models extraction technology can operate in several modes of speed. Usually it is 2-3 speed, for example, the standard number of speeds Spanish Cata - 3 normal mode plus one intensive, however, the latter depending on the model. When the electric motor is running at the speed change does not occur, it is safe to say this is a problem the control unit. Verify by visual inspection can be removed at the screen or to ring using a multimeter mentioned.
If suspicions were confirmed it is best to completely change the board with a new, without resorting to a partial repair. Repair is possible, but not the fact that the service life will be enough to avoid repeated failure in a short time.
reverse current
In some cases, the user may be faced with the output from the device off odors. This situation is most likely to occur on the upper floors of apartment buildings or in private homes in the derivation of the duct in the cellar. Out of the situation is relatively simple. You need to purchase and install a check valve at the junction with the sleeve. When the drawing the valve will open, providing free access to the ventilation of vapor, at shutdown valve closes and prevents reverse current.
excessive noise
There are times when brand new hood is excessively noisy. This, of course, not the rumble, but the constant and monotonous hum of quiet conversation at the level of two people can be a tangible stimulus. In most cases, nothing can be done about it. This disease is characterized by low-cost devices and little-known manufacturers is the result of careless assembly.
The only way to avoid this trouble - to pick up the technique with the level of noise, build quality, and the manufacturer's reputation.
Prevention of faults
Obviously, repair a broken cooker hood with his hands the thing entirely feasible. But it is better to do everything to avoid it necessary. To do this, follow the basic rules that will help to extend the working life devices:
- regularly clean grease and carbon filters, the first time in 3 weeks, the second time in six months;
- do not use the cooker hood with broken plate and the absence of her upcoming products;
- apparatus include a couple of minutes before the start of cooking and off 15 minutes after closure.
These simple recommendations plus the manufacturer's instructions to help the user to protect your device from premature failure, ensure its long-lasting performance and a comfortable atmosphere kitchen.
