DIY kitchen hood repair

The cooker hood has become a very popular and even irreplaceable household appliance these days. Many have already managed to make sure of the need for this device, since during the cooking process fats, fumes and small food particles are released into the air, which can harm human health.

The cooker hood produces efficient air purification.

In most cases, an air purifier is installed in the kitchen when a global renovation is carried out.

Unfortunately, even with very careful operation, the hood may fail over time, and then the owner will have two possible ways out of this situation:

• contact the service center;
• do all the work with your own hands.

Exhaust device

A standard kitchen air cleaner is nothing more than a simple exhaust fan mounted above the stove. It is equipped with additional filters that are designed to absorb fat and harmful vapors from the air during cooking.

Hoods are divided into two categories: filtering and exhausting.

• Filtering (coal cooker hoods) are the most simple in structure, respectively, and the price of such a device is somewhat cheaper. They work on the recirculation principle, that is, polluted air is cleaned and returned to the room. Carbon filters are provided for air purification.
• The exhaust hood is connected to the ventilation shaft, which allows it to completely remove the polluted air from the room. Such devices are considered more advanced than filtering devices. Of the filters, only a grease catcher is present here.

Such hoods require a complete ventilation system. If it is available, then the air is discharged into the mine, if not, then the specialists can take the pipe outside.

Modern hoods are capable of working in both modes. Most of them are equipped with multi-speed motors, which are not very powerful, but have a built-in relay for changing the speed.

Types of hoods according to the principle of operation.

Advice! Purchase a hood with a power reserve, because as the filters become dirty, the efficiency of the system decreases. As a result, the system ceases to cope with the tasks assigned to it.

When using the hood actively, you must ensure that the grease filter does not become dirty. If you do not make its timely replacement, then the efficiency of the system will sharply decrease. The filter change frequency is directly proportional to the frequency of use of the hood. On average, it is recommended to change the grease catcher every 3-4 months. Charcoal filters in a recirculation-type hood operate from six months to two years.

Frequent malfunctions of hoods

The hood repair manual is based on a number of probable malfunctions that most often occur during the operation of the device.

The hood does not remove odors

• Turn on the appliance a few minutes before you start cooking food. Switching off must be done about 15 minutes after the end of cooking. By following this rule, you can get rid of unpleasant odors in the kitchen once and for all. Also, the reason may be an untimely filter change.
• Inefficient operation of the charcoal filter. In this case, you need to check if the filter can be disassembled. If yes, then it should be removed, disassembled (as in the photo below) and replaced with coal granules.

To disassemble the charcoal filter, simply pry off the top cover with a screwdriver.

In the event that the filter cannot be disassembled, it must be replaced with a new one.

• To change the grease catcher, simply remove the wire shelf by placing it face down on the table. Next, you should disconnect the old filter. Then wash the wire rack and place a new grease catcher.

Removing the grill, disconnect the old filter.

This only applies to disposable grease catchers. They are easy to distinguish from reusable ones - they have an inscription that is clearly visible through the grill. When such a filter becomes unusable, the inscription disappears.

As for the fiber grease filters, they are reusable, that is, you can wash them in warm soapy water, and after drying, put them back in place. Be sure to accompany the filter change procedure with cleaning the air intake grille.

Stove lighting does not work

1. The light bulb may have burned out. If the fan is running and there is no lighting, then you should replace the bulb.
2. Defective switch. In the event that replacing the lamp does not solve the problem, check the serviceability of the light switch.

The hood does not turn on

In this case, there are several possible reasons for the problem:

• The device is not connected to the mains. Make sure there is voltage at the outlet.
• The device switch is defective. Check the switch using a tester. In the event that it does not ring, it should be replaced.

Check the switch. Perhaps the contact has moved away.

• There is no power supply. In this case, check the shield. It may well be that the machine has turned off or the fuses have blown.
• The power plug is defective. Check the plug.
• The plug fuse has blown. If the hood plug has a built-in fuse, check it and, if necessary, replace it.
• Internal wiring defective. With a tester, you should check the internal wiring. It may be damaged. Retighten the screws to remove the bad contact connections. Crimp the ends with pliers.
• Malfunction of the electric motor. Check the motor, and if the cause of the malfunction lies in it, then replace it without even trying to repair it.

Advice! In most cases, repairing an electric motor is unprofitable in purely economic terms, and the result obtained will not correspond to the money spent. It is much cheaper and more practical to buy a new motor.
