We repair kitchen extractor fan by yourself

Repair of kitchen extractor fans is almost always justified from a financial point of view, it is quite within the power of every home craftsman to fix a few small faults with their own hands.

How does the extractor fan Before you start repairing the extractor fan with your own hands, you should understand its structure. Such a technique can be of the exhaust (discharge) or recirculation type (the air is cleaned and released back), but in both types the asynchronous motor (8) is always the main working element.

In addition, in such a technique will necessarily be a fan (2), which may be axial or tangential. Axial is the blade, “tightening” the air inside. The air flow will pass along the axis of rotation of the engine. Fans of tangential type are evenly spaced blades-blades. Such a fan is preferable – its principle of operation provides increased efficiency.

Filters will definitely be in the extractor fan. For example, a low-end carbon filter (9) is put on the round input window of the motor, and the more expensive filter design with coal granules will be the one that has a rectangular shape and is installed immediately behind the fat. The fat filter, in turn, is immediately behind the working surface (12). There are also fabric filters and paper products with impregnation (disposable), but now the most widespread mesh reusable metal grease catchers. As for the control panel, it can be of a sensory or mechanical type, but it will always be a common unit, as shown in the photo below.

If the device provides for changing speeds, then there is a mandatory circuit that generates a control voltage. The design is also complemented by lighting. It can be incandescent, halogen or LED lamps. Repair the extractor fan with your own hands is easy if you act according to a certain algorithm. It is clear that first you need to decide on the problem. In the case when the extractor fan is broken and does not turn on, be sure to check the operation of the built-in lighting. This monitors the integrity of the power circuit, the correct connection to the outlet. If the bulbs work, then the problem is the engine or control system, in which case you need to buy new parts that fit your model extractor fan and are approved by the manufacturer. Spare parts for kitchen extractor fans are sold in specialized spare parts stores for household appliances and in online stores.

How to change the engine extractor fan Disconnect the power supply extractor fan. Remove the filters by pulling the tongue. Unscrew the bottom panel of the extractor fan, holding it underneath so that it does not fall. Disconnect the backlight wires so that you disconnect both panels from each other. Remove the extractor fan or remove it from the cabinet by unscrewing the screws and place it gently on the floor. Attention, the extractor fan is heavy, so it is desirable to remove it with a partner. Remove the fan from the engine, releasing the spring clip or other mount.

Now you need to remove the engine. To do this, disconnect the green ground wire from the screw on the extractor fan, and then cut the wires connected to the engine. Connect the new engine to the mounting plate, then place it in the exhaust housing, background wire.

Reinstall the fan blades, securing the spring clip. Install or re-install the extractor fan, reattach all the casing panels and connect the power supply, check the operation of the new engine
