Etna induction cooktop makes loud buzzing or humming noises at certain power levels.

Safety: Noise alone is not usually dangerous, but ensure cookware is stable and the surface is not cracked.

• Try different cookware: Use heavier, flat-bottomed pans to reduce noise.
• Change power level: Slightly increase or decrease the power setting to move away from the resonant frequency.
• Check mounting: If noise is excessive, disconnect power, remove the cooktop, and verify that the induction coils are firmly mounted with all screws and damping pads in place.
• Replace coil mounts: If rubber or felt pads are worn, replace them to reduce vibration.
