When one, several or all of the hotplates of an electric stove does not heat, the reasons can be very different: among them there are simple ones that you can easily fix yourself (problems with the outlet or power cable, the wrong cookware for the induction cooker), and complex ones, which can only be repaired by a qualified professional technician, for example, a malfunction of the control module or problems in the internal wiring.
What to do if the burner of an electric stove, hob or induction hob from Bosch, Ariston, Hansa, Beko and other brands is weakly heated - further in this article we will tell you how to find out the root cause of the breakdown, and what is better to do in such a situation.
In most cases, poor heating or incorrect switching on / off of the burner is associated with malfunctions of the sensors or heating element, but the reasons for this may be different.
Burned-out coil of a burner
Symptoms: one or all of the burners does not work.
One of the most common causes of an inoperative burner is a burned-out heating element: a spiral or nichrome thread. By the way, in modern stoves one burned-out burner can block the switching on of the entire electric stove.
If the burner is non-separable, you will have to change the entire burner, otherwise it is enough to replace only the spiral. Basically, you can do this work yourself. But it is better to call a specialist.
The burner spiral has cracked
Symptoms: the burner does not heat at all or does not heat well.
The spiral can not only burn out, but also crack after a strong blow or cold water getting inside the burner, which will cause a sharp temperature drop. If after that there was an open circuit in the burner circuit, it will not heat up at all, if some contact remains, then this can lead to weak or uneven heating.
Thermal protection has worked
Symptoms: one or all burners turn off by themselves
One hotplate or the entire stove can shut down spontaneously due to overheating: thermal protection is triggered and the power supply is interrupted. But why overheating occurs, it is necessary to understand separately and there are many reasons: a breakdown of a sensor or temperature regulator, a broken cooling fan - only an experienced craftsman can determine the exact cause.
Symptoms: cookware installed on the induction hob burner, does not "magnet", the burner does not turn on or heats up weakly.
If you have an induction cooker, the burner may refuse to work with the cookware, which somehow attracted it - read the instructions.
The power switch is broken
Symptoms: not one specific hotplate turns on, everything else works, heating may not work only in some switch positions.
One of the most common reasons why a hotplate does not turn on is a malfunction of the switch that regulates its heating. Prolonged service under severe high temperature conditions may loosen the contact springs or burn the contacts themselves. In order to determine for yourself that it is the broken switch that is to blame, you can try to connect another burner to it, but we do not advise you to engage in such complex experiments without special training. A defective switch must be replaced.
A defective temperature control sensor in the touch-sensitive hob will have the same consequences as a broken mechanical power switch. But it's much more difficult to fix something in the touch panel yourself - here you can't do without a good knowledge of the electric circuit of the stove and special diagnostic equipment.
Damage to the thermostat
Symptoms: the burner either does not turn on at all, or turns off after a while.
A faulty thermal sensor does not transmit temperature data to the control module, and that, naturally, turns off the hotplate or the entire stove in order to avoid damage to other parts of the stove due to overheating. It is worse if the sensor works, but incorrectly, for example, due to sticking of the relay contacts: then overheating is quite possible with all the ensuing sad consequences. If you notice that the burner turns off quickly, or, all the more, if it is clearly overheating, you need to urgently call a specialist who will understand the causes of the problem.
Control module failure
In modern devices, everything is controlled by electronics, so for some reason breakdowns or malfunctions in the "brains" of the stove, the consequences can be very diverse, including turning on and off one or more electric stove burners, their premature shutdown or spontaneous turning on.
