How to check the hood

With the invention of the hood, the process of cooking, especially in tiny kitchens of apartment buildings, has become much more comfortable. He flipped the switch and all the smoke and fumes from the stove rushed into the ventilation. But what to do if at one point, instead of the usual smooth hum, you heard an unpleasant intermittent grinding sound, or the fan did not hum at all?

Reasons why the kitchen hood could fail

During operation, the performance of the device is affected by many negative factors that can become a source of failure. The most basic of them are:

1. Heat. As a rule, the hood is located in close proximity to heating devices, constantly interacting with hot air, evaporating heated fat and various liquids. Of course, manufacturers provide protection for the device from high temperatures by creating a layer of thermal insulation coating inside the hood body. But over time, the thermal insulation layer can deform, crumble and lose its thermal protective properties.As a result, the working parts of the devices begin to heat up, the plastic elements of which fail under the influence of high temperatures.
2. Excessive load. During constant use in an apartment, especially at maximum ventilation, all rotating parts of the device are subject to constant friction and, as a result, rapid wear.
3. Household pollution. During operation, all kinds of greasy contaminants enter the ventilation, which, when interacting with dust, are deposited on the intake openings, as a result of which air circulation is disrupted.

As you can see, there are many reasons for device failure. Let's look at the most common breakdowns and how to fix them.

How to check if the hood is functioning correctly

What signs may indicate that the device is malfunctioning?

1. The hood does not turn on. Typically, this may indicate that there is no electrical current flowing to the operating mechanism of the device.
2. The device is functioning normally, but there is no air flowing into it. This is usually a sign that the intake holes in the hood grille have been contaminated with grease or dust.
3. When the device operates, extraneous sounds occur: grinding, squeaking, intermittent and uneven fan sound. This indicates that a breakdown has occurred inside the working mechanism.

REFERENCE! If even when the hood is operating you can smell odors in the room, this does not always mean that it does not draw in air well. Often the owner operates it incorrectly - the air purifier should be turned on a few minutes before the start of the cooking process, and turned off a few minutes after the end.

Having determined the location of the fault, you can begin to eliminate it.

How to eliminate detected malfunctions in the hood

Many breakdowns that occur in the device can be corrected independently.

REFERENCE! There is no need to call a professional at the first sign of a problem with your kitchen air purifier. It is often enough to have basic skills in working with a screwdriver and to imagine the structure of the device.

Ways to solve the problem of malfunctions in the operation of the hood:

1. If the ventilation grille is dirty, just unscrew a few bolts on the bottom side of the device, remove the holding frame and carefully remove the grease trap. Usually, in the instructions, hood manufacturers indicate which cleaning agents can be used when washing it. Thoroughly clean the grease trap of any dirt and reinstall it.
2. If there is a fault in the electrical wiring, you need to carefully inspect the wires going to the outlet, the outlet itself, the plug and the power cord. If you find places where the passage of electric current is disrupted, you should replace the damaged section or the entire wire.
3. If a breakdown occurs in the working mechanism of the hood, then it would be best to contact a service center. Specialists will determine what exactly is faulty and replace the faulty part.

Preventing the normal functioning of the hood

As you know, it is much easier to prevent a breakdown than to fix it. Sometimes seemingly minor violations of the operating rules of the device can lead to more than serious consequences. Therefore it is necessary:

• Before installing the hood, carefully read the instructions for use included in the kit;
• strictly comply with safety requirements;
• do not bend the electrical cord when connecting the device;
• carry out preventive cleaning of grease-removing membranes at the first signs of a decrease in hood draft;
• Do not expose the device to prolonged, continuous operation; do not forget to turn it off when leaving the kitchen.

If you follow these simple rules, the device will serve you for many years, delighting you with its impeccable performance.
