If you own an induction hob, then you are probably aware that it is completely different from the traditional hobs in terms of performance. Induction hobs transfer heat to the pan through a magnetic induction coil placed beneath each heating zone. Once you switch the induction hob on, it generates a patchy electromagnetic field that in turn creates inductive currents in the magnetic base of the saucepan. The outcome: the pan located directly over the heating zone heats up, without the hob actually getting hot. This allows for significantly rapid heating periods of time as compared to other hob substitutes, such as ceramic or gas. With that in mind, you have probably experienced some issues with your induction hob in terms of noise, as have many consumers. Read on to explore.
Induction cook-top humming sound
It is normal for the hob to produce humming sounds when boiling or cooking. Different types of cookware may produce slight sounds such as buzzes or hums. Lighter weight stainless steel pans produce more noise than heavier pans, like enameled cast iron. The sound level can also be influenced by the size of the pan and its contents.
Pan noise may also interact with adjacent elements at certain power levels to produce an intermittent “hum” or low whistle. You can reduce or eliminate these noises by raising or lowering the power levels of one or both of these elements. Generally, the more surface area on the element ring your pan covers, the lesser the noise.
Buzzing noise with high heat settings
This is normal. Once you reduce the heat setting, the noise should disappear completely, or at least quieten down.
Induction hobs are extremely energy efficient when it comes to cooking. One of their great advantages is that they do not generate any heat themselves. However, this absence of extraneous heat can actually have a side effect: it does not leave any hot air to warm up any cold surfaces that the water vapour produced by what you are cooking may come into contact with, unlike in a traditional gas or electric hob. As a result, some of the steam or water vapour produced during the cooking process may condense on these cool surfaces. The level of condensation will depend on several factors, including the type of cooking, the thickness and nature of the material used to make the surface, the temperature at the surfaces, and the ambient temperature in your kitchen. This can be controlled by switching your extractor on fifteen minutes before cooking and leaving it on for fifteen minutes after you’re done. Doing this will ensure proper circulation of air in your kitchen before cooking begins, and shortly after. You can also save energy and reduce excess steam by covering the pan with a lid when cooking, and reducing to a simmer when boiling is achieved.
Fan noise after switching the hob off
It is normal for the fan to run briefly after turning the induction hob off. Once the hob has cooled sufficiently, the fan will switch itself off automatically.
