Does the electric stove heat up badly? There can be many reasons for the occurrence of such a malfunction (from the lack of voltage in the network and ending with serious damage to the internal equipment modules). A specialist will be able to accurately determine the source of the breakdown (only after diagnostics).
The electric stove can break down for various reasons. The most common of them are:
damage to the burner coil or sensor
failure of the thermostat
broken power switch
activation of thermal protection
faults in the control module
problems with the wiring
choice the wrong type of cookware.
Some minor defects can be removed by the user himself. However, situations are often extremely difficult. Then it becomes necessary to contact the master of the service center and call him at home.
Burned out or cracked cooking zone coil. This part may stop functioning due to the depletion of its resource or external factors (ingress of various liquids, sudden voltage surges, etc.).
Depending on the degree of destruction, the burner may either not turn on at all or heat very weakly. If its design involves disassembly, then the spiral simply changes. If not, a completely new burner is installed.
Damage to the thermostat. Most often, the symptoms of this are manifested in the fact that the burner becomes too hot even at the lowest power settings (or vice versa: it heats up slightly at the maximum). Another sign of a defect is the unstable activity of the heater (constant switching on and off).
Atypical behavior of the unit indicates that the thermostat does not correctly transmit data about the current temperature to the control module. Because of this, the supply of current to the heater becomes unstable.
If you find the symptoms described, you should immediately contact a service representative who will replace the thermostat. Otherwise, a broken thermostat will lead to overheating of the burners and a complete shutdown of the device.
Power switch malfunction. During long-term operation, the power regulator begins to malfunction. The problem here may be associated with clogged internal contacts, mechanical damage to the switch or other defects. In such a situation, the hotplate can heat up at certain positions of the regulator and turn off at maximum or average values.
Installing a new switch will help to correct the defect. Thermal protection. Most modern models of electric stoves are equipped with thermal protection. It works automatically, turning off the power of the entire device or its specific department. This prevents spontaneous combustion, as well as a sequential cascade failure in all elements of the system.
There can be several factors by which the thermal protection is triggered: from a short circuit to a failure of the temperature sensor or the cooling system. In any case, you do not need to independently try to determine the type of defect and fix it. Most often, these actions lead to the formation of additional damage.
Sensor malfunction. In modern hobs with touch control, the power level regulator and heating temperature control may break. The external manifestations of the problem are similar to the breakdown of a mechanical switch on simple electric stoves. In this case, a broken sensor can completely block the hotplate or turn it on only at certain levels. All necessary actions must be carried out by a specialist.
Control module failure. Problems with the electronic control module can have different external manifestations: incorrect operation of the burners (weak heating, spontaneous shutdown), complete shutdown of the stove, etc. You can set it up yourself only when you have the necessary experience.
Wiring fault. Wiring problems often cause the stove to stop functioning. The fault should be looked for not only in the mains wire itself, but also in the socket and plug. Any traces of thermal effects (for example, melted plastic) or violation of the integrity of the outer sheath of the cable indicate possible malfunctions in the equipment.
The stove is connected to the network through one power cable, the power from which is distributed through the terminal block separately to the hob and the oven. Closing and oxidation of contacts on the junction box inside the plate is one of those types of malfunctions that cannot be identified visually without disassembling the product. In this situation, it is best to disconnect the stove from the power supply and call the master.
Unsuitable cookware. This problem is faced exclusively by owners of induction hobs or free-standing hobs. When you start using the frying pan or saucepan you just bought, no heating occurs. It has nothing to do with the current state of the device. The source is the user's inattention and ignorance of the features of induction cookers.
Its principle of operation is based on converting the energy of an electromagnetic field into heat. To start the heating process, dishes with a ferromagnetic bottom must enter the working area. Any other object that is not magnetic (ceramics, glass, aluminum, some metal alloys) will simply not heat up. What to do? Just change dishes. Manufacturers themselves help to choose the right kitchen utensils: they mark the bottom of pots and pans with a special icon, which indicates that the container can be used on an induction hob.
