Induction cooktop makes loud buzzing or humming noises during operation.

Note: Some humming or buzzing is normal with induction cooktops, especially at higher power levels.

• Test with different cookware: Try another induction-compatible pan; noise often varies by pan construction.
• Reduce power: Lower the power setting slightly to see if noise decreases.
• Check installation (for installers): Verify the cooktop is securely mounted and not flexing in the countertop cutout.

If noise is excessively loud, metallic, or accompanied by error codes, the coil or mounting may be defective and should be inspected.
