Possible Causes
• Loose or disconnected wire harness between control board and touch panel assembly
• Faulty touch control panel or sensor board
• Defective main control board with failed communication circuits
• Moisture or condensation on the touch control panel interfering with sensor function
• Power supply voltage fluctuation on the 240V circuit (electric/induction models) or 120V control circuit (gas models)
• Cracked or damaged glass cooktop on induction or smoothtop models affecting sensor readings
• Poor electrical connection at the home circuit breaker or cooktop power cord connection
• Software glitch or corrupted control board programming
Safety Checks You Can Do
• Turn off the circuit breaker dedicated to the cooktop for 60 seconds, then switch it back on to perform a hard reset
• Check that the cooktop is properly plugged into its dedicated outlet and verify the outlet has power using another appliance
• For electric and induction models, confirm the cooktop is connected to a 240V dedicated circuit; for gas models, verify the 120V control outlet is working
• Inspect the cooktop surface for any cracks, chips, or damage on glass smoothtop or induction models
• Wipe the entire touch control panel with a soft, dry cloth to remove any moisture, condensation, or debris
• On gas cooktops, check that all burner caps and grates are seated properly and no burner components are loose
• Verify the touch controls are not in a locked mode by checking the display panel for lock symbols
• Ensure the cooktop area is dry and not exposed to excessive steam or water from cleaning
• Check your home's main electrical panel to confirm the dedicated cooktop breaker has not tripped
• Attempt to reset the cooktop by holding down the power button or designated reset button for 10 seconds if available on your model
