An Induction Hob Can Hum When It Cooks

When cooking on an induction cook-top, it is pretty normal to hear a slight humming noise. Depending on the type of cookware that you are using on the induction stove, it may produce some humming or buzzing. This is especially true for lightweight stainless steel cookware. You might not hear so much noise with heavier cookware like enamelled cast iron pans. The size of the cookware size, as well as contents, may also affect how strongly you hear the hum whilst cooking.

High Heat Settings

Induction hobs use heat to prep your meal but sometimes, high heat settings can produce a buzzing sound that some find alarming. A few people have likened the noise to the muffled sound of an old-fashioned phone. The buzz may be constant, continuing for several seconds, stopping, only to resume again. Sometimes, the sound may even be completely absent.

Heat-related buzzing can be caused by the hob itself or the cookware.

The process through which induction stoves heat cookware – by producing a magnetic field – can cause vibrations. The buzzing noise might become more obvious when the pots or pans have poor construction, uneven bottom surfaces, or loose-fitting parts or lids.

Are Induction Hobs Noisy?

Should I Be Concerned About My Induction Hob’s Fan?

In rare cases, yes. But the good news is that in almost every instance when your hob makes a humming noise due to the fan, nothing is seriously wrong. You should, however, have it checked out if the noise sounds choppy, gets louder or is accompanied by strange smells. Ironically, you should also worry if you can no longer hear the fan’s buzzing.

Most people become aware of this buzzing just after they have finished cooking and switched the stove off. But why does an induction hob need a fan to cool it down when a hob does not actually generate any heat? The fan activates to cool the internal electronics which sometimes get hot and needs to cool down. This fan is in-built and automatic, simply kicking into action the moment you switch off the hob.

Understanding The Role Of Condensation And Your Hob’s Humming

Condensation happens when water vapour comes into contact with a cold surface. The vapour then turns into water droplets. Unfortunately, condensation happens naturally with most cook-top stoves. The kitchen can be a steamy place and a lot of the steam hangs around your hob thanks to boiling pots. Condensation is then attracted to the cool glassy surface of the hob.

One might not worry so much about condensation and other types of traditional cook-tops. Indeed, their hot surfaces take care of the condensation by evaporating the water and effectively preventing the droplets from gathering on the cooking surfaces. Induction hobs cannot produce the same heat. This leaves them vulnerable to a layer of condensation.

Depending on the types of materials you have in your kitchen, such as wooden or stainless steel cupboards and kitchen tops, water damage from the moisture made by condensation can be a concern. It might also ultimately lead to a noisy hob and in some cases, a damaged hob.

How Do I Deal With Condensation In The Kitchen?

There is a simple way to deal with this. Turn on the stove’s extractor for a while before cooking and also leave the extractor on for a good 10-20 minutes after you have finished cooking.

Condensation is also a huge problem in the bathroom. Find out why your bathroom ceiling is wet and how to deal with the problem successfully.


Quick Tips To Reduce Induction Hob Noise

  • Raise or lower the power levels of the stove’s elements as you cook until the stove becomes quieter. This can help you to find the perfect heat setting for that pot.
  • Ensure that the induction hob pans that you use are large enough to cover the surface area of the element.
  • Invest in good quality cookware that is preferably made of ferromagnetic materials, especially cast iron that is enameled.
  • Ensure that your cookware’s lids, handles and other pieces are well attached and fitted so that they do not create a noise when the pots are cooking.
