When using your induction hob, you may notice that it is pulsing. It could be that you are hearing a buzzing noise, or even watching the bubbles in your boiling water rise and then fall, thus showing the pulsing sensation of the induction hobs. But why do induction hobs pulse? 

Some induction hobs pulsate simply out of design. It usually happens when the hob has been at a high temperature for a while and is now cooking at a lower temperature. It is therefore just adapting to the new temperature and can be completely normal and expected. 

However, that isn’t always the case, and your hob could need a repair if there are deeper issues in play. Let’s take a look at why that might be the case.

Is it normal for induction hobs to pulse? 

In some cases, it can be normal for induction hobs to start pulsing. Some users note that induction hobs of a poorer quality have a tendency of pulsating, for example, or more commonly doing so when they are moving from cooking on a high temperature to cooking on a lower one. So, how do you know when it is a problem? 

The first sign that this could be a genuine problem is if your induction hob has never pulsated before. If you have had the hob for some time and it is just now starting to pulsate, then it could be a sign that there is an underlying issue with the hob, or maybe with the circuit onto which it has been installed. 

Another way of noticing whether or not it is an issue is by seeing when it pulsates. If it pulsates as soon as you turn the hob on, as opposed to having a steady cooking setting until it has lowered in temperature then that too could be a sign of an issue. It’s always a good idea to check your operations manual and to consult your manufacturer if you are concerned.

Do all induction hobs pulse? 

No, not all inductions hobs pulse – in fact, many note that a poor quality induction hob is more likely to pulse than a high-end installation.

That being said, even well-known branded hobs can pulse. This could mean that there is more of an issue with the circuit or maybe something surrounding the hob. As such, you’re going to need to look carefully at how everything is set up.

That said, induction hobs can make a lot of noise – just keep a close eye on yours if problems persist.

What do I do if my induction hob is pulsing? 

The first thing that you should do is check your instruction manual. The manufacturer may have accounted for such problems, discussing the pulsating in a troubleshooting section – indicating that it is indeed something to be expected and not as big of an issue as it could be. 

However, if there is no mention of the pulsating in the instructions manual, then it is a good idea to contact the manufacturer directly. They will have a good idea about what could be wrong with the hob and will be able to give you suggestions about what you should do moving forward. 

You may have to contact a professional engineer to come to check out your induction hob – whether at the suggestion of your manufacturer or otherwise. If you are unsure about the quality of your installation, try contacting an alternative professional to provide extra insight.

Whatever you choose, it is always best to contact a regulated and trained professional – be they on behalf of the manufacturer, or an independent electrician. Your induction hob may not be dangerous to use at the moment, however, it is never worth the risk. 

Should there be a problem with the appliance, then your warranty should allow you to have the appliance replaced and a new one installed quickly – unless it is easy to repair. Circumstances such as these prove why it’s so important to look for warranties that cover you for longer periods.

In many cases, it may be worth investing in an extended warranty. Be sure to read about your chosen induction hob model and manufacturer carefully before buying – and you’ll likely be able to make a clear decision on what to expect.

Do I need to be worried if my induction hob is pulsing?

A pulsing induction hob is never going to be a good sign, but unless it is happening more and more frequently, or interrupting your meal preparation, there may not be much cause for concern.

To avoid these issues altogether, it’s a good idea to check reviews and ratings for your chosen model online before you buy. If there’s frequent discussion of pulsing problems, then it may be worth looking for something a little more reputable.

Otherwise, don’t be afraid to reach out to your manufacturer for help – they will know how to best get your induction hob back to full health.
