Induction Cooktop Humming Sound
Humming sound while cooking or boiling is normal. Slight sounds, like hums or buzzes may be produced by different types of cookware. Heavier pans, such as enameled cast iron produce less noise than a lighter weight multi-ply stainless steel pan. The size of the pan and the amount of contents can also contribute to the sound level.
When using adjacent elements that are set at certain power level settings, pan noise may interact and produce a low whistle or intermittent "hum". These noises can be reduced or eliminated by lowering or raising the power level settings of one or both of the elements. Pans that completely cover the element ring will produce less noise.
