Why an electric stove is shocking and how to fix it

Why an electric stove is shocking and how to fix itIt happens that some time after the installation of the electric stove, it begins to “bite” its owner, that is, for some reason, its body begins to be shocked. It can be very gentle strokes, but pleasant, of course, is not enough, especially if you touch the stove with wet hands.

This problem must be eliminated as soon as the first symptoms appear, otherwise the matter can reach serious and life-threatening injuries. It is impossible to name one single reason here, therefore, a diagnosis should be made and the root of the malfunction should be correctly identified in order to eliminate it later. If you are more or less versed in the device of the electric stove and have basic skills in handling a multimeter and an indicator screwdriver, then in principle a simple diagnosis will be affordable. However, it is important to remember that any repair operations with electrical appliances promise danger if a person does not have experience and qualifications ...

 

Typical electrical problems with washing machines

Typical electrical problems with washing machinesIf you try to start the washing machine, but nothing happens, you need to make sure that the indicators on the display or the LEDs on the front panel of the washing machine are on. If the indicators do not light, check that there is voltage in the outlet. With an indicator screwdriver, you will only check the presence of a phase, so you need a two-pole voltage indicator or a multimeter in the AC voltage measurement mode.

If there is no voltage, we disassemble the socket and see if the wires are intact. If not, you need to look for problems in the wiring, but for now, an extension cord from the nearest working outlet will help you. If there is voltage in the outlet, then you need to check the cord of the washing machine, for this you need to examine the machine from the outside and determine where the wire goes, then you need to disassemble the machine body, in the beginning you can try to remove the top coverif the wire goes further - you can try to put the machine on its side ...

 

Household electric motors and their use

Household electric motorsThanks to global electrification, our life has become more comfortable and cozy. The life of a modern person is impossible to imagine without electrical appliances. A lot of household appliances, which are entirely powered by electricity, are used today in every home. Even rural life is replete with various devices that make the economy more progressive and less burdensome for its owner.

In this article we will touch on the topic of household electric motors that faithfully serve in our vacuum cleaners, in washing machines, in coffee grinders, in food processors, in microwave ovens, and in many other household appliances, using which we don’t even think about how they are arranged, and how important the role of the electric motor is in them. Household electric motors are not many kilowatt industrial units, it is often the result of engineering to optimize common principles...

 

Why spark brush motor

Why spark brush motorCollector electric motors differ from other types of motors by the presence of a collector-brush assembly. The assembly provides electrical connection of the rotor circuit with the circuits located in the fixed part of the motor, and includes a collector (a set of contacts located directly on the rotor) and brushes (sliding contacts located outside the rotor and pressed against the collector).

During the operation of the commutator motor in a power tool, sparking brushes can sometimes be observed. In some cases, this symptom leads to an early breakdown of the power tool, and in some it does not bode well. One way or another, it is useful in each case to understand what the cause of sparking is, in order to take the right measures in time if necessary.In this article, we will consider the causes of sparking brushes, as well as measures to combat the problems that cause this phenomenon.Intermittent mechanical brush contact ...

 

Why do heating elements burn on water heaters and washing machines and how to replace them

Why do heating elements burn on water heaters and washing machines and how to replace themTEN - a tubular electric heater or thermoelectric heater, a device for converting electricity into thermal energy. They differ in shape, purpose, for example, water and air, power and size. They are installed everywhere where you need to heat something: in electric stoves, heaters, etc..

Heating elements sooner or later burn out, while they can either simply stop working or be punched into the housing, which will result in a risk of electric shock. Let's look at the reasons for their failure, structure, differences and methods of replacement.The electric heater consists of a tubular body, inside of which there is a spiral or thread made of a material with high resistivity, for example nichrome, fechromAnd so on. The spiral is separated from the body by an electrically insulating but heat-conducting material, such as periclase ...

 

LED strip malfunctions and repair methods

LED strip malfunctions and repair methodsLED strips are widely used in decorative lighting and functional lighting, but from time to time they fail completely or partially, in connection with which there is a need for their repair or replacement. Often, you can do just replacing a small part of it, which will reduce repair costs. In this article, we will cover typical problems with LED tape.

Before starting the discussion, I note that the main emphasis will be placed on common tapes with 12V power, 24V tapes are similar in design, and in the end we will consider the features of repairing network (220V) tapes. First, let's figure out what the LED strip consists of and why it is flexible. LED tape can be divided into two parts: a flexible printed circuit board and LEDs and current-limiting resistors. On one side, the flexible circuit board is coated with adhesive. A metallized layer is applied on the second side ...

 

Types of fuses for household appliances

Types of fuses for household appliancesThose involved in the repair of equipment must have heard the joke: "The device burned out, protecting a fuse." No matter how ridiculous it may sound, such situations happen quite often. Nevertheless, a fuse is an obligatory part of almost all types of household appliances. They are needed not only to protect the device itself, but also so that damage does not progress until fire. In this article we will tell you what fuses are used in household appliances.

An electric fuse is a device or switching device designed to disconnect a circuit from a power source at a current significantly higher than the rated current. In simple words: if the device for some reason began to consume excessive current, the fuse will open the circuit. It is installed in series with the protected section of the circuit.Fuses or fuses are the most common because their device is simple, as is their manufacture ...

 

Why do transistors burn?

Why do transistors burn?Even the best, original and true field effect transistors always fail for the same reason - because of exceeding any of their maximum permissible parameters. We will not take into account mechanical damage to the cases and legs, instead, we note two main harmful factors - violation of the thermal regime and excess of critical voltage. Violation of the thermal regime means the excess of the permissible temperature of the crystal, which is usually directly related to the increased current, so we will consider in detail this aspect of the problem.

Generally speaking, we can say that the field effect transistor fails either from overvoltage or from overheating.And if there are no reasons for exceeding the permissible parameters, then the transistor will retain both its operability and the operability of neighboring components, not to mention the nerve cells of the owner of the device for which this transistor was intended ...
