Safety Checks You Can Do
• Turn off power to the cooktop at the home circuit breaker for 60 seconds, then turn back on to perform a hard reset
• Check that the cooktop's dedicated circuit breaker is in the ON position (for 240V electric/induction models) or that the 120V outlet is functioning properly (for gas control modules)
• Verify the cooktop is fully plugged into its dedicated outlet with no loose connections at the wall
• Inspect the cooktop surface for cracks, chips, or damage on glass smoothtop or induction models that may indicate internal water intrusion
• Ensure no moisture, spills, or condensation are present around the touch control panel or vents
• Confirm all burner caps and grates are seated correctly and not blocking vents (gas models)
• Check that the cooktop touch controls are not locked by holding the lock button for 3 seconds
• Dry the control panel thoroughly if any moisture is visible and allow 24 hours for complete drying before retesting
• Attempt to clear the error by pressing and holding the reset or cancel button on the control panel for 5 seconds
