Symptoms
• Cooktop will not heat or ignite burners
• Error code F2 displays on the control panel or digital screen
• Touch controls become unresponsive or locked
• Some burners work while others do not respond
• Cooktop shuts down unexpectedly during cooking
• Control panel may beep repeatedly or continuously
Possible Causes
• Faulty temperature sensor (RTD or thermistor) on the cooktop surface or burner element
• Loose or corroded electrical connections between the sensor and control board
• Damaged sensor wiring or connector due to age or moisture exposure
• Control board failure or electronic component malfunction
• Power supply issue affecting 240V (electric/induction models) or 120V (gas control) circuits
• Moisture or condensation inside the control panel affecting sensor signal
• Software glitch or control board firmware error requiring reset
Safety Checks You Can Do
• Turn off the cooktop and allow it to cool completely for at least 15 minutes
• Check your home's circuit breaker panel to ensure the breaker serving the cooktop is in the ON position
• For electric or induction models, verify the cooktop is properly plugged into a dedicated 240V outlet and the connection is secure
• For gas cooktop models, verify the 120V control outlet connection is secure and functional by testing another appliance in that outlet
• Inspect the cooktop surface for visible cracks, chips, or damage on the glass or ceramic surface that may affect sensor operation
• Check that the touch control panel is completely dry; if wet, wipe with a soft, dry cloth and wait 30 minutes
• Verify the touch control lock feature is not enabled (check your model's user manual for lock deactivation steps)
• Perform a hard reset by switching off the dedicated circuit breaker or unplugging the cooktop for 60 seconds, then restore power
• Wait 2-3 minutes after power restoration to allow the control board to fully initialize before attempting to use the cooktop
• If the error clears after reset but returns during cooking, the sensor or control board may require professional service
Safety First
Always disconnect the appliance from power before performing any checks. If you are unsure about any step, please contact a qualified technician.
