Cooktop makes loud buzzing or humming noises during induction operation.

Safety first: Ensure cookware is stable and the cooktop is properly installed.

• Change cookware: Try a heavier, thicker-bottomed induction pan. Noise often decreases with better cookware.
• Adjust power: Reduce the power setting slightly; some noise is normal at high power levels.
• Check mounting: From below, verify that the induction coils and mounting brackets are tight and that no panels are rattling. Tighten screws as needed.
• Isolate vibration: Add felt or foam strips (heat-resistant) between loose cabinet trim and the cooktop frame if they are vibrating.

Mild buzzing is normal for induction, but sudden changes in noise level can indicate a loose component.
