What is this symptom?
Is your induction cooktop powering on but not heating cookware effectively? This common issue can stem from using incompatible cookware, improper positioning, or even a child lock being enabled. Uneven heating can disrupt your cooking experience, but there are simple troubleshooting steps you can take to resolve the problem and get back to cooking quickly.
Possible Causes
Incompatible cookware
How to Identify: Cookware fails magnet test (magnet does not stick, bottom not flat or smaller than cooking zone, weak heat transfer
Part: Cookware
Incorrect cookware positioning on cooktop
How to Identify: Cookware off center of induction zone or partially outside target area causes weak heating
Part: User setup
Child lock or control panel lock enabled
How to Identify: Controls appear unresponsive and lock icon is displayed; cooktop does not start heating despite inputs
Part: Control panel/settings
Internal sensor or control board malfunction
How to Identify: Persistent error codes, sudden stops, or erratic heating not explained by cookware or settings
Part: Temperature sensor or control PCB
Power supply or electrical issue
How to Identify: Cooktop powers inconsistently, breakers trip, or limited power delivery affects heat output
Part: Electrical supply/connection
DIY Solutions
Verify and use compatible cookware
- Place magnet on bottom of cookware; if it doesn’t stick, cookware is not induction‑compatible.
- Use flat, magnetic stainless steel or cast iron cookware of appropriate size.
- Center cookware on induction zone making full contact with cooktop surface.
Disable child lock or incorrect setting
- Look for lock icon on control panel.
- Refer to manual for specific button sequence to toggle child lock.
- Ensure proper heating mode is selected after unlocking.
Reset cooktop power
- Turn off cooktop and circuit breaker controlling it.
- Wait 10–20 seconds then restore power.
- Test heating function again.

User Suggested Solutions
-
Ensure cookware is induction-compatible. Check for a magnetic base by placing a magnet on the bottom of the pan. If it sticks, it’s compatible. If not, replace with suitable cookware.
-
Inspect the induction coil for damage. If faulty, replace the induction coil. Disconnect power, remove the cooktop cover, and replace the coil with a new one.
-
Check the power supply. Ensure the cooktop is plugged into a dedicated circuit and not overloaded with other appliances. If circuit issues are suspected, consult an electrician.
-
Examine the control board for any visible damage or burnt components. If damaged, replace the control board. This may require professional assistance.
-
Ensure proper ventilation around the cooktop. Clear any obstructions and allow for adequate airflow to prevent overheating.
