Induction cooktop zone displays a blinking U and does not heat.

Safety first: Ensure the glass is cool before repositioning cookware.

• Use correct pan size: Select a pan with a base diameter that matches or slightly exceeds the inner circle of the cooking zone.
• Center the pan: Place the pan in the middle of the zone and reselect the power level.
• Check pan material: Test with a magnet; if it does not stick, the pan is not suitable for induction.
• Try another pan: If U still appears with a known good pan, the zone’s detection circuit may be faulty and require service.
