Independent repair of a modern electric stove

Today, the popularity of household appliances powered by electricity is constantly growing, but during operation, minor breakdowns sometimes occur. An electric stove is present in every modern kitchen - it is the heart of this room. When a kitchen assistant fails, many home-made craftsmen are interested in whether it is possible to repair the electric stove with their own hands?

What you need to repair

First, the home master, who has decided to repair the electric stove by himself, should at least understand electrical appliances, know the basic fundamentals of electrical engineering and safety rules when conducting this type of work.Secondly, we need confidence that you will be able to perform such a complex repair, and most importantly - to find and fix root cause of failure. Third, you need to prepare special tool.

When dismantling the electric stoves, you will need screwdrivers for various purposes: under the cross or slot, with different thicknesses, the so-called sting specialists. Be sure to need the keys - horn and cap, pliers, nippers. For interior work, a soldering iron, side cutters, an insulating tape and, of course, a special device for measuring voltage and resistance will be useful in the body of the product.

The photo shows only an approximate set of the necessary tool - during operation, the range of the tool used has the property to a significant expansion.

Construction and main components of the electric stove

The electric stove looks very impressive - it is a complex household appliance, but his design is pretty straightforward, and all major work items are in a special heat resistant casingwhich is made of stainless steel.

The principle of operation is similar to all electrical household appliances: the current, passing through the heating elements (heating elements), heats them to a predetermined temperature. The stove has a few burners on the hob, and their number varies: at least two, and the standard - 4 pcs. For example, the budget electric cooker Dream 15M has only two burners and a small oven, and the product of Belarusian engineers Hephaestus has a standard set of burners and a volume oven.

Burner structure quite diverse. The classics are burners on an enamelled cooking surface with heating elements inside, modern ones are solid ceramics surfaces with heaters of various types embedded in them. Consider the main types of burners.

1. Old domestic options are equipped with products from cast iron, they slowly heat up and also cool down, creating a steam effect in the kitchen, but they are resistant to moisture and high temperature.
2. Tubular spirals - they are made from a hollow tubeWhen heated, such devices not only give off heat, but also contribute to the circulation of warm air inside their casing, which greatly increases the efficiency of their work. These products are very difficult to repair yourself.
3. Burners from ceramics very simple in construction, they are easy to repair at home - a spiral of nichrome placed in special cells in a circle and fixed.In modern models, glass-ceramic solid plates are increasingly used - they are more durable and easy to clean.
4. Halogen devices - These are special burners with a similar radiator, which are installed in different places of the cooking surface. A stove with such burners provides fast heating, per second, and low power consumption, so they are the most economical, but only professional craftsmen can do repairs.

All models of modern plates for the transfer of current to the burner use power wire special section, in addition, they are connected to the regulators and thermostats to protect them from overheating.

In different models, the heating level is controlled in different ways: by manually changing the cooking mode or special timers and alarms that control.

Common Malfunctions

During operation of electric stoves, users may experience such typical malfunctions.

1. Sometimes when you turn on the product appears burning smell - it is necessary to turn off the stove and inspect the burners, on which could remain the remains of burnt food, which are easily removed.When the smell of burning plastic or rubber appears, you should call the master.
2. Heating element does not heat up - here is the fault of the hotplate or connecting wires, but first you need to check the controls, maybe the contact went away.
3. Is impossible adjust the optimum temperature heating the burner - it is necessary to repair the switch.
4. The burner does not heat up - if you have a spiral inside, then it often breaks due to overheating or ingress of moisture. In this case, it is very easy to fix the electric stove - replace the spiral, and that is all the repair.
5. The oven does not work well. - It is necessary to ring the heating elements, 100% is their fault, need to be replaced, since they are not repaired.

Attention! If a electrical connection performed independently, no service will do the repair for free - you have lost the right to warranty service.

Troubleshooting algorithm

The process of finding equipment failure does not depend on the product model and type cooktop or burners installed on it.

1. First, with a voltmeter, you must check the voltage. It is not necessary to exclude the possibility of the automatic activation of the protection, the isolation of the wiring may be broken or the reason lies in the outlet. If so, then it is necessary to disassemble it, and clarify the reason.
   
2. If the indicator lights on the control panel, and the stove does not work, then there is no current supply to the burners, which means that the stove must be disassembled.
3. It is necessary to check the correct operation of the control unit of a mechanical or electronic type - measure by the instrument the current flow to the burner terminals.
4. Check the heating elements of each burner to find a burned out spiral.
   

5. Inspect all thermal sensors, relays and various regulators.

Our task is to find the fault and locate the resulting problem. After completing all the recommendations, you will find the cause of the failure of the equipment, and how to fix it, we will tell a little later.

We disassemble the product

Plate models are different not only in their external form, but also in size, construction - it is impossible to describe the disassembly algorithm that will fit all products. A common factor for all is the presence of thermal insulation layer - here it is necessary to work with him extremely carefully. Users should be aware that asbestos dust from gaskets under the burners in old models is very harmful to health - keep this fact in mind when disassembling archaic plates.

initially dismantled hob - it is fastened with screws, if unscrewed, it can be easily removed. Under it are burners, lead wires to them and mechanical temperature controllers, which are located on the front panel.

All this must be dismantled to get to the lower part, where the heaters of the oven are located.

At the modern electric stove with a hob from glass ceramics dismantling the case for repair will be different - in order to get inside, you just need to remove the top panel.

Important! Repair of glass-ceramic hob surfaces is performed only by service center specialists - amateurs with superficial knowledge and lack of experience should not touch such complex equipment.

Troubleshoot

The following are common electrical breakdowns. Some of them can be eliminated independently, others require professional diagnostics and repair.

Idle burner

If you have a stove with burners, then in order to change them, you must act according to this method.

1. Turn off the nut and remove the ground.
2. Under it may be a ring or bracket, pressing part to the base.
3. The ring is attached with a threaded connection or simply inserted into a special hole. In the first version, we lubricate the threads with oil and carefully try to unscrew it from the body; in the second case, use a screwdriver to hook it and remove it.
4. If a model of the old model, it is better to replace the burned out burners with modern and economical samples that are suitable in size.
   
5. If the burners are in good condition, the reason for the failure is in control unit - a large amount of current passes through mechanical regulators, and carbon deposits can form on the delicate contacts, which are cleaned with fine emery paper.

Heating switch

Here is a step-by-step guide on how to repair or replace a switch on electric cookers.

1. If there are no clicks when turning the regulator, it means that it is faulty.
2. There is an original check of its state: we put the regulator in the middle position, we apply voltage to the plate, the automatic protection must be activated - it will turn on and off after 30 seconds.
3. Before removing the handles, you must study the instructions - on some models they don't understand (Gefest, Kaiser).
4. First, adjust the knobs on the outside, then unscrew the front panel.
5. Below it is a bar that must be removed to get to the broken regulator.

Electronic control unit

If you hear a click when you turn on the relay, then you need to check for the presence of a signal - if it is not present, the reason lies in the microprocessor itself or in the output stage. To repair the electronic unit, you must have a schematic diagram and understand the complexities of radio engineering. If there is no knowledge and skills, it is better to turn to specialists - otherwise you will have to buy a new electric stove.

Modern electric stoves on heating elements quite often use the thermostat for heating the cascade type burners.

Power controller

Sometimes there is a failure of such a regulator, which can be found an identical replacement. Experienced masters advise to install triac type such a device, just need to take with a margin of power and current strength. In some models it is installed on the same board along with the radiator. When the hotplate of the stove is working at maximum, and the heating control cannot be changed, this indicates that the controller has failed for an unknown reason - it must be urgently replaced.

Each user must understand that modern household appliances are crammed with electronics, each model has its own, different from the other, manufacturing and control nuance - mechanical or electronic. Foreign intervention without special knowledge and skills can adversely affect the delicate filling of electric stoves.
