A low hum or buzz from an Electrolux induction cooktop is not always a sign of trouble. Induction works by passing a fast-changing magnetic field into the pan, and some pans vibrate slightly when that happens.
Hums that are no cause for worry
- A steady low hum on the highest settings, most often with a heavy pan.
- A buzz from thin or layered pans that gets quieter on a lower setting.
- Soft clicking on low settings while the cooktop pulses its power to hold a gentle simmer.
- Fan noise after cooking, while the cooktop cools itself.
If the sound changes when you swap pans, the pan is the likely cause. Try a heavier, flat-bottomed pan and see if the noise drops.
Sounds worth a closer look
Test with the same pan on each zone, then note what you hear.
- A loud buzz on one zone only, even with different pans.
- A fan that never stops or grinds when it runs.
- A crackle or pop from under the glass.
- Noise paired with an error code, or a zone that drops out.
A cooling fan clogged with dust or with a worn bearing can get loud, and it matters because the cooktop slows or stops heating when it runs hot. Keep the space under the cooktop clear for airflow, as your installation guide allows.
What sound alone cannot tell us
Sound narrows the search, but it does not name the part. A buzz may come from the fan, a power board or a loose mounting, and we confirm which with a test before we replace anything.
Older units
We repair induction cooktops that are out of warranty. If the repair would cost more than the cooktop is worth, we say so and leave the decision with you.
Zone and fan trouble is covered on our cooktop repair information page, and the service area page shows whether your city is on our route. Reach us by phone or the contact form with the pan you tested and any code you saw. You approve the quote in writing before we open anything.
