Important Tips for Frigidaire Models

Ensure child lock or control panel lock is not engaged as it may prevent proper heating and response.

Possible Causes

Cookware compatibility or placement issues

How to Identify: Use a magnet test on cookware — if a magnet doesn’t stick to the pan base or the pan isn’t centered on the cook zone, inconsistent heating is likely due to poor induction coupling.

Internal control board or sensor error

How to Identify: Cooktop powers on and responds but heating is inconsistent with correct cookware; possible error codes or unresponsive zones.

Part: Control board / temperature or pan detection sensors

Overheating safety shutoff or ventilation problems

How to Identify: Cooktop heats briefly then shuts down; may be hot to touch or fan runs constantly, indicating overheating triggers.

Part: Ventilation / thermal safety system

Induction coil or internal power delivery fault

How to Identify: No heating across zones even with compatible cookware and correct settings; potential electrical smell or error codes.

Part: Induction coil / power electronics
