Basic malfunctions of the ElG microwave

Service center specialists note a number of the most common breakdowns in microwave ovens manufactured by South Korean manufacturers:

1. The food is not heated at all or very weakly. The cause is a lack of power or a faulty generator.
2. The device does not turn on. The breakdown is caused by problems in the operation of the transformer, fuse or control unit.
3. The stand does not rotate. The situation occurs due to damage to the electric motor or drive.
4. Sparks appear in the chamber during operation. Diagnostics of the serviceability of the camera, mica filter, and magnetron is required.
5. The microwave makes sounds and hums when it is running. Non-specific noise occurs when a transformer, magnetron or fan fails.

Frequent breakdowns of LG microwave ovens

Despite the reliability of products of this brand, failure sometimes occurs. This can be caused by mechanical damage, hidden defects, or the exhaustion of certain elements. Typically, microwave oven repair technicians at home are faced with the following common types of malfunctions:

• The appliance does not heat food or does it too weakly.
• Doesn't respond to buttons, gets lost in the program.
• When turned on, it knocks out traffic jams, or turns off prematurely.

All of these malfunctions are directly related to serious damage to the magnetron, board or drive. In microwave ovens with grill and multi-cook functions, the heating element or convection or backlight may additionally break down.

Important: no matter what happens, you should not try to make repairs yourself, following instructions on the Internet. Remember that without a special tool and certain knowledge, you can not only aggravate the damage, but also get injured. Therefore, the best solution would be to contact the service.

Stages of the wizard's work

Before starting to repair the microwave oven, the technician will conduct diagnostics to accurately determine the problem unit. This operation is performed free of charge. Then the procedure and cost of work are agreed upon with the client. If there are no objections, dismantling of the equipment and replacement of damaged parts begins. Upon completion, the microwave oven is assembled and tested for functionality. The certificate of completion of work and the warranty card are filled out. Instructions are provided on the correct use of equipment.

What is a magnetron

This is a generator of ultra-high frequency (microwave) radiation in a furnace. The electromagnetic waves it emits heat food by moving the water molecules in the food. It turns out that the food is heated without external thermal influence. Therefore, the operating temperature in a microwave oven cannot exceed 100°C - the boiling point of water.

How it works

Here you can remember the school physicist who rightly said that science will come in handy.

The operating principle and circuit of this vacuum diode resembles an ordinary light bulb. High voltage is applied to the body, which is the cathode. The power is connected, elementary particles - electrons - rush to the anode.

What does the anode consist of? Copper sleeve (cylinder, tube, lamp) with vacuum sections inside and a tungsten filament. There are magnets on the sides that create a magnetic field and set a spiral trajectory for the particles. Electrons, moving through the resonator at breakneck speed, excite high-frequency currents. A powerful microwave flow arises, which enters the oven through a waveguide (antenna). The device is protected from overheating by aluminum radiator fins.

If the food is not heating, you need to check the magnetron.

Repairman services

The inability of a microwave oven to perform its main function—heating cooked food—occurs with any model and quite often. This may occur due to manufacturing defects, physical wear, non-compliance with operating rules, or mechanical stress. A microwave repair technician will check the electrical circuit, magnetron, repair a detected fault or replace a failed part.

It is not uncommon for the tray to stop rotating. To check the functionality and existing defects, specialists test the engine circuit and check the operation of the drive system. Problems with the motor can be corrected by replacing the windings or gears in the gearbox. Before turning to experts, you should make sure that the tray is not overloaded and that the grooves of the plate coincide with the rotation mechanism. You can fix these problems yourself.

If the microwave fails to turn on, the transformer is diagnosed, the ECU is tested, and the fuse is checked. Common causes are a broken power cord, a failed door locking mechanism, or damage to the temperature sensor.

Cost of additional services

1 — Without taking into account the cost of a service engineer’s visit 2 — For Moscow, the city limits are considered to be the territory limited by the Moscow Ring Road 3 — Calculation formula: departure within (21-50 km from the city limits) + (30 rubles x distance over 50 km from the city limits) Example for the Moscow region: distance 93 km from the city limits (MKAD) = 900 + (30 x 43 km) = 2190 rubles including VAT. Example for Russian cities: distance 117 km from the city limits = 700 + (30 x 67 km) = 2710 rubles including VAT.

Attention! The cost of repairs does not include the cost of spare parts and consumables.

How to make a magnetron cap

I was given the task of quickly and cheaply repairing a magnetron and microwave oven . After reading the opinions of those experienced in this matter once again, I decided to rummage through the defective radio elements to find similar cap sizes. And I found one! Found an old swollen electrolytic. The diameter was correct by eye.

I carefully gutted the capacitor. To do this, I needed narrow-nose pliers, with which I pulled out the rubber plug and capacitor plates, folded in a spiral.

Next, it was necessary to trim the edges of such a cap with a file and drill a hole. Having tried a drill with a diameter of 3 mm on an old cap, I found it suitable for this undertaking. At low speeds, I drilled a hole in the center of the cap and went through it again with a fine file. Having given the cap a slightly oval shape, I pressed it tightly into the desired place. In the end it should look like .

Or you can just buy it.

Then we collect everything to the heap in reverse order. It is interesting that a hole appeared on the inner wall of the microwave oven just opposite the location of the emitter . There was a lot of soot around this hole.

As we know, carbon deposits in the form of fine coal dust - a product of combustion of any substance (in this case, paint) conduct electricity quite well, so we clean off such carbon deposits in all places with sandpaper .

The good news is, of course, you need to paint the area where the paint is peeling off and install protective plastic or a mica plate. But a different decision was made. A friend finally bought a microwave cover without installing a mica plate. Thus, the result was a cheap and cheerful repair of the magnetron of the LG microwave oven Daewoo .
