This may be caused by a tripped circuit breaker, faulty surface element switch, or a defective power connection. For electric cooktops, loose wiring or a failed control board can also prevent the burners from working.

If a single burner doesn’t heat, the element itself may be burnt out or disconnected. On gas models, it could be a clogged burner port or a faulty igniter that needs cleaning or replacement.

Continuous clicking usually means the igniter is wet or dirty. Food spills or moisture near the ignition system can block the spark. Once dry and cleaned, the igniter should function normally again.

Uneven cooking often comes from warped pans, improper burner calibration, or an issue with the element sensor. For induction units, incorrect cookware type or size can also cause this issue.

Induction cooktops require magnetic cookware. If the pan isn’t induction-compatible or smaller than the heating zone, the unit won’t detect it. Check that your pan is flat-bottomed and made of ferrous material like stainless steel or cast iron.

Breaker trips indicate a short circuit or electrical overload. Faulty heating elements or control boards can cause sudden current surges. A qualified technician can inspect wiring and components safely.

Induction cooktops may produce a light hum when operating normally. However, excessive noise can signal loose internal components or high-voltage transformer vibration. It’s best to have it inspected if the sound is loud or new.

Heat rising from the cookware or poor ventilation can warm the knobs. This is normal to a degree, but if they become too hot to touch, seals or insulation may be damaged and need repair.

Error codes indicate electronic faults such as sensor failure, overheating, or touch control malfunctions. Consult your owner’s manual or contact a technician with the specific error code for diagnosis.

If you notice sparks, electrical smells, gas leaks, or repeated tripping of breakers, stop using the appliance immediately and call a professional. DIY repairs can be hazardous with high-voltage or gas systems.
