Repair and disassembly of the electric stove with your own hands
Today the popularity of home appliances, running on electricity, is constantly growing, but in the course of operation sometimes there are insignificant breakdowns. An electric stove is present in every modern kitchen - it is the heart of this room. When the kitchen helper fails, many home craftsmen are interested, whether it is possible to carry out repair of an electric stove by own hands?
What you need for repairs
Firstly, homemaker, who decided to repair the electric stove himself, must at least understand electrical appliances, know the basics of electrical engineering and safety rules for this type of work. Secondly, you need confidence in that, that you will be able to perform such complex repairs, and most importantly - to find and eliminate the root cause of failure. Third, it is necessary to prepare a special tool.
When dismantling electric stoves, you will need screwdrivers for various purposes: under the cross or slot, with different thickness, the so-called sting specialists. You will definitely need horn and cap wrenches, trade winds, nippers. For internal works in the case of a product the soldering iron is necessary, side cutters, insulating tape and, of course, special device for measuring voltage and resistance.
The photo shows only an approximate set of necessary tools - during operation, the range of tools has the property of significant expansion.
Design and main components of the electric stove
The electric stove looks quite convincing - it is a complex household appliance, but its design is quite simple, and all the main working elements are in a special heat-resistant housing, which is made of stainless steel.
The principle of operation is similar to all electrical appliances - electricity, passing through the heating elements (TEN), heats them to the set temperature. The stove has several burners on the hob, and their number varies: at least two, and standard - 4 PC. Example, in the budget electric stove Dream 15M only two burners and a small oven, and the product of Belarusian engineers Hephaestus has a standard set of burners and a three-dimensional oven.
The structure of burners is quite diverse. The classics are burners on an enameled cooking surface with a heating element inside, modern - solid ceramic surfaces with built-in different types of heaters.
Consider the main types of burners.
- Old domestic versions are equipped with cast iron products, they heat up slowly and also cool down, creating a steam effect in the kitchen, but they are resistant to moisture and heat.
- Tubular spirals - they are made of a hollow tube, when heated, such devices not only give off heat, but also promote the circulation of warm air inside the housing, which significantly increases the efficiency of their work. These products are very difficult to repair yourself.
- Ceramic burners are very simple in design, they are easy to repair at home - the spiral of nichrome is placed in special cells in a circle and fixed. Modern models increasingly use glass-ceramic solid plates - they are more durable and easy to wash.
- Halogen devices are special burners with a similar emitter, which are installed in different places on the hob. The stove with such burners provides fast heating, per second and low power consumption, therefore, they are the most economical, but only professional craftsmen can do the repairs.
All models of modern stoves use a special power wire to transfer current to the burners, exept this, they are connected to regulators and thermostats, providing them with protection against overheating.
Different models control the heating level in different ways: by manually changing the cooking mode or special timers and alarms, who exercise control.
Common faults
Users may encounter these common faults while operating electric hobs.
- Sometimes when you turn on the product there is a smell of burning - you need to turn off the stove and inspect the burners, on which the remains of burnt food could remain, which are easily removed. When the smell of burnt plastic or rubber appears, then you need to call a wizard.
- TEN does not heat up - here is the fault of the burner or connecting wires, but first you need to check the authorities, maybe there is a lost contact.
- It is impossible to set the optimum heating temperature of the burner - it is necessary to repair the switch.
- The burner does not heat up - if you have a spiral inside, then it often breaks due to overheating or moisture. In this case, repair the stove is quite simple - replace the spiral, that's all the repairs.
- The oven does not work well - you need to call Teni, 100% it's their fault, replacement required, T. To. they are not repaired.
Warning! If the connection of the stove was performed independently, then 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 the type of burners or hobs installed on it.
- First, use a voltmeter to check the voltage. The possibility of triggering the circuit breaker should not be ruled out, the insulation of the wiring may be broken or the cause may be in the socket. If so, then it must be disassembled, and clarify the reason.
- If the indicator is lit on the control panel, and the stove does not work, then there is no power supply to the burners, means, you need to disassemble the plate.
- It is necessary to check up serviceability of the control unit of mechanical or electronic type - to measure with the device current receipt on terminals of burners.
- Check the heating element of each burner, to find a burnt out spiral.
- Inspect all temperature sensors, relays and various regulators.
Our task is to find the fault and locate the problem. Following all the recommendations, you will find the reason for the failure of the equipment, and how to fix it, we will tell a little later.
Disassemble the product
Plates are different not only in appearance, but also in size, constructions - it is impossible to describe the disassembly algorithm, which will suit all products. A common factor for all is the presence of a thermal insulation layer - so you need to work with it very carefully. Users need to know, that asbestos dust gaskets under the burners in the old models are very harmful to health - keep this in mind, when dismantling archaic slabs.
First, the hob is dismantled - it is fastened with screws, if you unscrew them, then it is easily removed. There are burners under it, wires, leading to them and mechanical temperature controllers, which are located on the front panel.
All this must be dismantled, to get to the bottom, where are the Shadows of the oven.
In a modern electric hob with a ceramic hob, disassembly of the housing for repair will be different - in order to, to penetrate, you just need to remove the top panel.
Importantly! Repair of glass-ceramic cooking surfaces is performed only by specialists of the service center - amateurs with superficial knowledge and lack of experience are better not to touch such complex equipment..
Troubleshoot
The following are the most common breakdowns of electric stoves. Some of them can be eliminated by yourself, others require professional diagnosis and repair.
The burner does not work
If you have a stove with burners, then, to change them, it is necessary to act according to such technique.
- Unscrew the nut and remove the ground.
- There may be a ring or a bracket under it, presses the part to the base.
- The burner is fastened with a threaded connection or simply inserted into a special hole. In the first case, lubricate the thread with oil and carefully try to unscrew it from the body, in the second case - hook up with a screwdriver and remove.
- If the model is old, then burnt-out burners are better to replace immediately with modern and economical models, suitable for dimensions.
- If the burners are in good condition, then the reason for failure is in the control unit - through the mechanical regulators is a large current, and deposits may form on the delicate contacts, which are cleaned with fine sandpaper.
Heating switch
Here are step-by-step instructions, how to repair or replace a switch in electric stoves.
- If there are no clicks when turning the knob, then it says so, that it is faulty.
- There is an original check of his condition: put the regulator in the middle position, apply voltage to the stove, protection automation should work - turn on and off through 30 sec.
- Before removing the handles, you need to read the instructions - on some models they do not understand (Gefest, Kaiser).
- First, the adjusting knobs on the outside are removed, then unscrew the front panel.
- There is a bar under it, which must be removed, to get to the broken regulator.
Electronic control unit
If you do not hear a click when you turn on the relay, then you need to check the presence of the signal - in its absence, the cause lies in the microprocessor or the cascade at the output. To repair the electronic unit, it is necessary to have a schematic diagram and understand the complexities of radio engineering. If you do not have the knowledge and skills, it is better to turn to specialists, otherwise you will have to buy a new electric stove.
Modern electric stoves on Teny quite often use a thermostat for heating the cascade type.
Power regulator
Sometimes such a regulator breaks down, which can find an identical replacement. Experienced masters advise to install a triac type of such device, only need to take with a margin for power and amperage. In some models, it is installed on the same board with the radiator. When the hob burner is running at maximum, and the heating control cannot be changed, then it says so, that the regulator failed for an unknown reason - it urgently needs to be replaced.
Every user must understand, that modern household appliances are stuffed with electronics, each model has its own, different from others nuance of manufacture and management - mechanical or electronic. Interference without special knowledge and skills can adversely affect the delicate filling of electric stoves.
