DIY electric stove repair

Various devices can be used for cooking, but due to their frequent use and intensive work, they are particularly prone to breakdowns. Repair of electric stoves can be done with your own hands at home, without taking bulky equipment to a service center.

Design and Diagnostics

Despite the external complexity, this device has a very simple design. All working elements are installed in a special heat-resistant cabinet made of alloy steel.

The operating principle of the electric stove is based on the heating of the heating element by the flow of electric current through it. The device is equipped heating elementsthat are necessary for cooking. They are ceramic, tubular, halogen, solid.

1. Ceramic burners are presented in the form of a tube, so they can be used for any electric stoves and it is very easy to repair them yourself. The spiral is placed in the hole in the plate and fixed using special parts. Nowadays, glass ceramics are more and more often used, which is more affordable and durable, in addition, it lends itself to washing;

2. Halogen burners are considered economical, they work due to halogen lamps with reflectors. These lighting devices are installed in various areas of the hob and provide quick heating and low electrical energy consumption;
3. In old domestic tiles (Dream, ZVI and others), cast-iron spiral heating elements were often installed. They slowly heated up, but after a shutdown they gave off heat for a very long time. Separately, it should be noted their durability and resistance to moisture and high temperatures;
4. The tubular spiral is made of a hollow pipe. When heated, it not only gives off heat, but also promotes the circulation of warm air inside itself, which allows to increase the efficiency of the device. This type of burner is the most difficult to repair yourself.

To power the stove, a power wire is used, which is connected to all burners. In addition, they are also connected to regulators and thermostats, which act as a safety system for the device. After switching on, the wire begins to transfer energy to the heater, which is necessary for cooking. It is necessary to control the heating level and the burner using the appropriate knob. Many household stoves Ardo (Ardo), Indesit (Indesit), Electrolux (Electrolux), Zanussi (Zanussi) and others, in addition to these devices, also have timers and signaling devices. They help control cooking time.

Unlike gas stoves, electric stoves are considered quite safe in everyday use. Their repair and maintenance can be easily performed independently, and their durability is much better than gas models. In particular, this is because they can be cleaned at home, and not wait for the arrival of a specialist.

Typical malfunctions:

1. During operation, a burning smell appears. If the smell of burnt food bothers you, then repair is not needed; you need to clean the cooking surface. If it stinks of plastic or rubber, then you need to urgently call an electrician;
2. The hotplate does not heat. The reason may be a lack of voltage, a problem with the spiral or control handle. Need to repair the burner or its wire;
3. The heating temperature is not set. Here, the mode switch repair will definitely be needed;
4. The hotplate does not heat up. A common problem with desktop and stationary stoves is that their spirals crack. They can collapse as a result of impact or from a sharp temperature drop (for example, the spiral is heated, and cold water accidentally gets on it). This is precisely the reason for the lack of heating of the burner or uneven heating of food. Self-repairing a spiral is very easy to carry out without the help of a master - most often it just needs to be replaced;
5. Poor oven operation. Most likely, the problem also lies in the breakage of the spiral.

It should be noted right away that the branded service will not undertake to carry out warranty repairs after an outside intervention. Therefore, if you do not have such experience, it is best to immediately contact specialized workshops.

Plate disassembly

Before you start repairing the device, you need to disassemble the case and get to the main elements. Depending on the design, threaded connections may be located on the panel or on the back wall of the Ariston (Ariston), Beko (Veko), Bosch (Bosch) and other electric stoves. They must be carefully unscrewed and removed. The table is attached with four screws; if you remove them, the panels can be lifted and removed to the side.

You will see wires that fit the burner - these are power cables and switches. They must be removed, because otherwise, further disassembly will be impossible. Hotplate has the following form:

1. First, the ground clamp nut is turned away;
2. She is carefully removed;
3. Under grounding there may be a ring or bracket that serves to tighten the part against the base;
4. The burner can be mounted either on the thread or simply inserted into the hole. You need, depending on its design, grease the threaded element with oil and unscrew the part from the housing or simply pry it with a flat screwdriver and remove it.

After you will have access to the internal connections of the device. It should be noted that the main elements of the hob are located directly below it, below (on the bottom, under it, on the back wall) are parts of the oven.

Repairs

Let's consider how the ceramic burners of Hansa (Hans), Gorenje (Combustion), AEG and others are cleaned. Be sure to disconnect the device from the network, otherwise you may be shocked. With a damp rag, moisten the dirt on the surface of the burner and wait a few minutes, then gently clean the growth with a sponge or soft brush. In no case can you use a metal brush, otherwise you can damage the integrity of the spiral and powder spraying.

Step-by-step instructions on how to replace or repair a switch in household electric stoves:

1. It is necessary to turn off the power and turn the switch knob from the off position to minimum heating. In the process, lye should be heard, which indicates the operation of the thermostat;
2. If there was no click, the controller is faulty. For an additional check of the thermostat, you need to leave it in the middle position and turn on the power - the protection must turn on and off every half minute;

   

3. Before removing the handles, be sure to read the “User Guide”, some models of plates are non-separable (Hephaestus, Kaiser);
4. The first to be removed are the handles that adjust outside. After that, using the screwdrivers, the front panel is unscrewed;
5. Under it is a bar that presses the switches. She also needs to unscrew and remove the broken part.

What to do if the spiral is cracked:

1. Unplug the hob. In most cases, the repair of the spiral is impractical, so it will need to be replaced;
2. Remove the top hob;
3. Under it is either an opening for ceramic heating elements or a recess for solid cast-iron or halogen;
4. You need to very carefully pry off the part and remove it. Pre-disconnect the contacts from the switch and the power cord;
5. Install the replacement spiral in the same way.
