Induction cooktop zone cycles on and off rapidly or makes loud buzzing noises.

Safety first: Ensure cookware and glass are cool before handling.

• Try different cookware: Use a heavy, flat-bottomed, induction-compatible pan. Thin or warped pans can cause noise and erratic cycling.
• Check power level: Some cycling is normal at low power settings. Test at medium power to see if behavior improves.
• Inspect coil mounting: Disconnect power, remove the cooktop, and check that the induction coil is firmly mounted to the underside of the glass. Tighten any loose screws.
• Replace power module: If noise is excessive and persists with proper cookware and mounting, the induction power module may be defective and require replacement.
