Induction cooktop makes a loud buzzing or humming noise, especially at high power.

Safety first: Noise alone is not usually dangerous, but always use cookware recommended by the manufacturer.

Steps:

• Try different cookware: Use a heavier, flat-bottomed pan designed for induction. Noise often decreases with better cookware.
• Adjust power level: Reduce the power setting slightly. Many induction systems are noisiest at maximum power.
• Check coil mounting (qualified person): If noise is excessive or new, disconnect power, remove the cooktop, and inspect the mounting screws and brackets securing the induction coil to the glass. Tighten any loose hardware.

Note: A mild humming or clicking is normal for induction, but sudden changes in noise level may indicate a loose component.
