Part: Cookware detection sensor
Faulty control board or internal electronic failure
How to Identify: No response after power checks, resets; error codes may appear; touch panel unresponsive.
Part: Control board/electronics
Overheat or safety sensor shutoff

DIY Solutions
Check and restore power supply
- Verify cooktop is receiving power; test outlet with another device.
- Check circuit breaker/fuse box; reset breaker or replace any blown fuses.
- Confirm that power cord is fully plugged in if external plug exists.
Ensure cookware compatibility
- Place a magnet on the bottom of cookware; ensure it sticks firmly.
- Use only induction‑compatible, flat‑bottomed cookware of appropriate size for zones.
- Remove non‑induction cookware before attempting to operate the cooktop.
Reset the cooktop
