Symptoms
• Cooktop will not turn on or respond to touch controls
• One or more cooking zones or burners are unresponsive
• Burners ignite but shut off immediately (gas models)
• Display shows E2 error code on the control panel
• Touch controls appear to be locked or unresponsive
• Cooktop beeps repeatedly or continuously
• Some zones work while others do not function
Possible Causes
• Moisture or water on the touch control panel interfering with sensor detection
• Temperature sensor failure on one or more cooktop zones
• Faulty control module or circuit board malfunction
• Loose or damaged electrical connection between the control board and heating elements
• Cracked glass cooktop surface on smoothtop or induction models affecting sensor functionality
• Child lock feature accidentally activated on the control panel
• Power supply voltage fluctuation or insufficient 240V (electric/induction) or 120V (gas control) reaching the cooktop
• Grease or debris buildup on the glass surface affecting touch sensor accuracy
Safety Checks You Can Do
• Turn off the cooktop and wait 10 minutes for it to cool before attempting any checks
• Locate your home electrical panel and verify the circuit breaker for the cooktop is in the ON position; if tripped, switch it OFF then back ON
• Inspect the power cord and wall outlet connection to ensure the cooktop is fully plugged in and the connection is secure
• Check that your cooktop is connected to the correct voltage: 240V dedicated outlet for electric and induction models, or 120V outlet for gas control modules
• Wipe the entire touch control panel with a soft, dry cloth to remove any moisture, grease, or debris that may be blocking sensors
• Perform a hard reset by switching OFF the circuit breaker for the cooktop for 60 seconds, then switch it back ON
• On smoothtop and induction models, inspect the glass surface for cracks or damage that could affect sensor performance
• On gas models, remove and reseat all burner caps and grates to ensure they are properly aligned and seated
• Check if the child lock feature is activated by looking for a lock symbol on the display; consult your user manual for the specific button combination to deactivate it
• Verify no error code reappears after the reset and test one burner or zone at a time to isolate any non-functioning areas
• If the error persists after these checks, discontinue use of the cooktop until professional service is arranged
Safety First
Always disconnect the appliance from power before performing any checks. If you are unsure about any step, please contact a qualified technician.
