Symptoms
• Cooktop will not heat or ignite despite control inputs
• Error code E1 displays on the control panel or digital screen
• Touch controls are unresponsive or intermittent
• One or more burners fail to operate while others may function
• Cooktop shuts off unexpectedly during cooking
• Beeping sound accompanies the error display
• Control panel is frozen or locked in error state
Possible Causes
• Temperature sensor failure or disconnection inside the cooktop cavity
• Faulty touch control board or control panel circuit failure
• Loose or corroded electrical connections between the control module and heating elements
• Damaged wiring harness between the 240V or 120V power supply and internal components
• Malfunctioning relay or switch on the main control board
• Glass cooktop surface crack on smoothtop or induction models interfering with sensor function
• Power supply voltage irregularity from home circuit breaker or dedicated outlet
• Moisture or debris on touch controls preventing proper signal transmission
• Failed burner ignition sensor on gas models
• Control board software glitch requiring reset
Safety Checks You Can Do
• Turn off the cooktop and allow it to cool for 5 minutes before attempting troubleshooting
• Check your home's circuit breaker panel to ensure the cooktop's dedicated breaker is fully engaged; if tripped, switch it off completely, wait 30 seconds, then switch it back on
• Verify the cooktop is firmly plugged into its dedicated outlet (240V for electric and induction models, 120V for gas control modules) and that the outlet is functioning
• Inspect the entire cooktop surface for visible cracks, especially on glass smoothtop and induction models, as these can trigger sensor errors
• Wipe down all touch controls with a clean, dry cloth to remove any moisture or residue that might interfere with sensor input
• Check that burner caps and grates are seated correctly on gas models and not blocking air vents or sensors
• Perform a hard reset by switching off the cooktop's circuit breaker for 60 seconds, then switch it back on
• Attempt to clear the error code by pressing any reset or cancel button on the control panel
• Ensure the cooktop controls are not in a locked or child-lock mode, which may be preventing normal operation
• Test individual burners if possible to determine whether the error affects all heating elements or only specific ones
• Check that nothing is obstructing ventilation openings or sensor windows on the cooktop base
Safety First
Always disconnect the appliance from power before performing any checks. If you are unsure about any step, please contact a qualified technician.
