What is the reason for that, that the electric stove does not work, and its main faults

December 14, 2019

These plates are much safer to operate, than gas - no open fire, but if used carelessly you can get an electric shock. The products are very reliable, but sometimes users call the service center, to report - the electric stove broke. Certainly, overhaul of such high-risk household appliances must be performed by a qualified craftsman. But in some cases, if the electric stove does not work, you can cope on their own with some knowledge and skills: you just need to know, what is the cause of the fault.

conducting diagnostics

Such characteristic disturbances in stable work of a product quite often meet:

  • burners and / or the oven does not heat up;
  • indicators, appeared;
  • one of the burners does not heat up well;
  • the backlight in the oven is not switched on.

There are many reasons for such violations, one of them - the automatic machine of protection against an overload at sharp jump of tension in a city power supply network worked. If the machine did not work, and the electric stove shows no signs of life, then a diagnosis should be made.

  1. First of all, you should check for mains voltage - maybe, turned off the power supply throughout the house. If all is well, then check the protection automation on your electrical panel, carefully inspect the terminals and look for burns, then disassemble the socket for a similar inspection. If everything works on the shield, and there is no voltage in the socket - call a wizard.
  2. There are options, when everything works fine, but there is no current at the input terminals of the plate - the reason is in the plug of the cord from the product, possible wire breakage, or loose contact of its mounting, therefore the hob does not switch on.

In the third variant it is possible to eliminate defect independently - it is necessary to disassemble a plug and to tighten screws of fastening of a wire, or reconnect, cut the wire, remove the braid, clean the veins, and connect them to the contact point.

The product is not included

Why the indicators do not work on the stove, no hotplate heating, there is no reaction to switching modes? The reason lies in the lack of electric current to the product. To locate plate faults, it is necessary to do everything in stages:

  • check the voltage in the socket with a multimeter, if not - turn off the home network, disassemble and eliminate the detected wire break;
  • if everything works in the socket - disassemble the plug and do a similar test;
  • then check the cord connection cord - maybe, there was an internal break in the vein, it needs to be replaced;

The second reason may be a burnout of the heating element of the burner or oven heater - they are not repairable, they are simply replaced by new devices. There is also such an option: the lights are on, but there is no heating of the burners and the oven, why it happens? In this case it is necessary to understand without haste. First, everything must be inspected visually: whether all connections are tightened properly, did not go away or where the wire, or there is a melting of PVC protection, indicating the burning of veins. In this case, reconnect, eliminating the scorched area.

Third, quite often the reason - the switch can break, so the hob or oven just doesn't turn on.

Importantly! Do not attempt to disassemble the switch, then it will be difficult to install all the springs in place, this requires skill and extensive experience. If you have identified, What is the fault of this device - just replace it, in the store you can easily buy a similar model.

oven failure

The most common problem is that there is no backlight inside the device, usually, there are two reasons.

  1. There is no contact of the supply wire with the lighting system - check the button, which is responsible for turning on the backlight, replace in case of breakage.
  2. Burnt out light bulb - the ceiling protects it from high temperatures, but that's how they are arranged, which very often burn out, from the smallest voltage drop.

When there is a short circuit in the electrical system of the stove, the first to burn out the lamps in the oven.

oven fan

To better distribute the heat in the oven over the entire area, the designers have installed a powerful fan, which can sometimes malfunction: rotates continuously or does not turn on at all. This type of failure is related to the control unit, therefore, it is useless to carry out repairs yourself - you need the appropriate equipment for diagnosis, to accurately install, change the fan or the unit itself.

There is no heating of the heating element

When the oven heats up slightly, then the main reason lies in the serviceability of the heater. These products, as well as heating elements of burners of a cooking surface, they cannot be repaired - they need to be replaced. Sometimes, which happens very rarely, the thermostat may burn out, which regulates the temperature inside the device - it is dismantled and a new one is installed.

Such a malfunction is very rare: the hostess turns on the oven, and the product immediately shuts off completely. When checking the circuit breaker on the electrical panel is found out, that he has cut off the power supply to the product - a short circuit may occur, it is necessary to change TEN.

induction option

When the electric hob with induction hob does not work, then the possible reason for this may be a circuit breaker or a special fuse - it melts when the voltage rises, disconnecting the entire electrical circuit. For various reasons, the contacts between the control unit and the power supply board or between it and the touch panel may not be switched on, due to oxidation or formation of scale. Only a specialist can understand all the difficulties - here you need to change the burner unit or touch control panel.

bad heating

Weak heating of the surface of the induction hob of the electric stove can occur due to this, that the bottom of the vessel is much smaller than the diameter of the latter, or not enough contact - dishes with a deformed bottom. Smart burners do not heat up in this case. To troubleshoot, you need to use only quality utensils, which is suitable for induction hob.

Another reason for poor heating is the loose fit of the burner unit on the inside of the glass-ceramic hob.. In this case it is necessary to adjust the springs of the clamping device. This can happen with severe overheating of the induction winding, which is extremely rare.

The burner does not work

Very often such problems in the operation of induction hobs are the fault of the user:

  • the diameter of the bottom of the dish should be at least 12 cm - this will provide a sufficient area of ​​contact with the cooking surface;
  • the thickness of the bottom should be within 2-6 mm;
  • first choose a burner, place dishes on it, and then the power of the cooking mode is set.

If the rules of operation are followed and the recommended utensils are used, then the reason for refusal may be as follows:

  • the temperature sensor has failed;
  • there is no heating in the pairs of burners on the left - their connection to the power supply board and the control unit is broken;
  • when the same happens with the right block - there is no contact in the terminal box, you need to check the fuse, if it burns out - install a new one.

At such malfunctions it is necessary to call the master from service, and not to open the electric stove - only he is able to make the correct diagnosis, to determine the problem with the power supply, controls or the burners themselves. Minor repairs and electric hobs require minimal skills and knowledge, in case of major breakdowns - contact professionals.
