Why does my induction cooker hum and whistle? Should it buzz at all?

Some electric stoves may make a slight noise when operating. Most often it can be seen in the operation of induction cookers. As a rule, manufacturers indicate this feature of the stove in the instructions. And besides, this hum is quite quiet and not annoying. But there are situations when initially a stove that worked silently suddenly begins to hum like a transformer, whistle or make other loud sounds. Such manifestations indicate equipment malfunctions that need to be addressed urgently.

The stove is humming

The operation of an induction cooker is not silent, it hums or even buzzes evenly: this is the sound of the induction coils working when interacting with the cookware. This may annoy some people, which is why this item is included in the “cons” section, but in general, any cooking is not a silent activity, and the humming will very quickly be drowned out by the noise of frying or water pouring from the tap. In new models, the noise is becoming less and less, but specialized dishes also help. It costs more than usual, but the manufacturers promise an almost complete absence of buzzing in addition to improved thermal conductivity and a perfectly flat bottom surface.

What is better, a heating element or an induction cooker for a moonshine still?

The heating element has a higher efficiency, since it is located directly in the environment that it heats. ... The heating element is more convenient because the moonshine still can be placed in any secluded place with an outlet, even in an inconvenient, damp and dirty one. And there is no need to build any stove for it, even a small one.

Troubleshooting methods

A malfunction associated with extraneous sounds, as a rule, is not a consequence of fatal changes in the operation of the stove. However, opening the device casing on your own and subsequently interfering with the operation of the unit can have an extremely negative impact on its technical characteristics. To avoid this, it is better to entrust the repair of an electric stove to specialists.

Is it possible to eliminate noise with your own hands?

Most of the sounds made by an electric stove during operation can be eliminated independently. For example, do not use dishes with thin or uneven bottoms. Use dry dishes.

Some sources of sound must simply be taken for granted, such as the sound of a sheet of iron bending when temperature changes.

Well, if the hum that appears indicates some kind of malfunction of the electric stove, then you should not fix the problem yourself. Only specialists who have a special permit to work with electricity can work with electrical equipment. Any intervention in the operation of equipment by a non-specialist can be harmful to human health. In addition, in the absence of the necessary knowledge, the breakdown can be aggravated, and this will complicate future repairs and make it more expensive.

Induction hob: pros and cons

Induction cookers are in great demand abroad, but the Russian market is still wary of them. Is this justified? We have already dispelled five popular myths that stop you from buying: “Induction hob: 5 myths.” However, induction has objective disadvantages and advantages, which we will discuss in this article. Let your choice of stove be informed!

Common breakdowns

If the hob clicks and , the main source of the malfunction is the burner relay. The problem can be determined by diagnostics by specialists. Do-it-yourself testing is impossible due to the need to disassemble the case. Another source of the problem is the use of unsuitable cookware, which causes heating to occur incorrectly and the electronics constantly changing operating parameters.

If the panel or stove clicks and at the same time, the cooling fan becomes the source of trouble. Its design has become contaminated with dirt, crumbs, grease, and the blades cling to them. Damage to the shaft and electric motor is possible.

Features of the malfunction

When an induction cooker clicks, you should pay attention to several nuances. This type of equipment is characterized by a clicking sound when heating up or operating at high power. If the stove clicks and works, then the relay regulates the power. There is also a sound when the heating level is reduced. In other cases, clicking is associated with malfunctions that arise for the following reasons:

Manufacturing defects. Parts break during the warranty period. More often in the first 1-3 months of active use. Repairs are carried out inexpensively or under warranty from the manufacturer.
Natural wear and tear. The relay has failed due to prolonged use. Requires replacement with a new one.
Incorrect use, care. Violation of the rules of use, cleaning, washing and other manipulations. We recommend that you study the instructions from the equipment supplied with the device upon purchase. If the brochure is lost, you can find it on the manufacturer's official website.

How to repair?

To repair an induction cooker yourself, you must immediately prepare diagnostic tools, a soldering iron and soldering devices. As a rule, the cause is either improper operation, a manufacturing defect, or liquid getting inside the housing.

If the stove does not turn on, the culprit may be a faulty power cord or a problem with the plug. Repair in these situations is carried out as follows: the stove is disassembled, the wire is cut at the entrance to the household appliance, after which the copper strands are stripped. Having assessed the condition of the conductor using a multimeter, it is necessary to remove that part of the wiring that is still in the housing. Finally, the power cord is installed and the pair of main conductors is correctly connected to the grounding conductor. The plug is also cut off and replaced with a collapsible three-pin product.

When the cause of the breakdown is a damaged fuse, it will be enough to disassemble the device, replace the failed part and return the induction system to its original state. To return the control module or touch panel to operation, you will also have to purchase a working element and replace it. Loose pressure springs are even easier to repair - they just need to be tightened to the level required, according to the instructions.

Ways to prevent electric stove malfunctions

In order for the electric stove to maintain its working condition for a long time, you need to properly and regularly care for it. Manufacturers recommend cleaning the surface of the stove after each use. But before cleaning, you need to make sure that all heating elements are turned off.

Glass-ceramic hob surfaces must be cleaned with particular care. Do not use abrasive cleaners or metal sponges when cleaning.

During operation, you should always handle the heating element with care. Do not place dishes with a wet bottom on it. If you find some kind of chip on the heating element, a break in the spiral, or it has become movable, then disconnect it from the power supply and call a technician.

When choosing cookware for an electric stove, you need to pay attention that the bottom should be flat. It is not advisable to use dishes with a thin bottom. The diameter of the cookware must match the diameter of the burner.

Saves energy and time

Induction cookers have a very high efficiency: about 90% of the total heat generated directly heats the food. This concentration allows you to save time: the frying pan heats up faster than on an electric stove, therefore the dish is cooked faster. If the stove operates for a shorter period of time, then less energy is consumed.

To prove the heating rate, we conducted an experiment: we boiled half a liter of milk at the same temperature on gas, electric and induction stoves. The results are as follows: electric stove - 5 minutes 32 seconds, gas - 4 minutes 48 seconds, and induction - 4 minutes 10 seconds. So for those who do not want to give up gas hobs with protruding burners in favor of smooth glass-ceramic hobs just because of the heating speed, this issue has now been resolved.

Other causes of humming

Users of some induction models are already accustomed to the fact that in normal mode the tile emits a low hum. This only means that the electromagnetic coil interacts with the material of the cookware. There is no need to be afraid of this. Usually this feature appears during the first launch.

There are several other situations in which the hum of an electric stove is normal.

Cooler operation. Some Gorenje and Kaiser models have 2 fans, which in extreme heat work at full power and create noticeable noise. To understand whether your appliance is working properly, turn on the blower mode in the oven and listen: if the sound is uniform, there is no need to worry; but if you hear that on one side the buzzing is stronger or a grinding sound appears, it is better to order a professional diagnosis.
Booster mode. One of the advantages of induction devices is the instant heating mode. This option, as it were, connects another energy source to the burner, which allows you to heat the pan 2-3 times faster. But as power increases, noise can also increase. Especially the brands Electrolux, Gefest and Zanussi.
Expansion of materials in old devices. If you do not have the newest metal electric stove, at high temperatures in the oven the walls of the device may bend, and then return to their original position with a quiet hum. There is no way to influence this. If you find these sounds difficult to tolerate, opt for a new glass ceramic hob. This material tolerates temperature changes well.
The dishes are not selected correctly. The instructions for any electric stove contain advice on what kind of cookware and how to use it. If you place a small ladle on a large burner, a buzzing sound may occur. The same thing can happen if you use a pan with a too thin bottom.

Whatever is causing the noise in your stove, you shouldn’t turn a blind eye to the problem. If the noise has appeared recently and is causing inconvenience, call a service technician by phone.
