Safety Checks You Can Do
• Turn off the cooktop and unplug it from the wall outlet
• Check your home's circuit breaker panel and ensure the dedicated cooktop breaker is in the ON position; if tripped, switch it OFF then back ON
• Wait 60 seconds with the breaker off, then switch it back ON to perform a complete electrical reset
• Allow the cooktop to cool completely for at least 30 minutes before attempting to use it again
• Inspect the cooktop surface for spills, debris, or moisture and clean thoroughly with a soft, dry cloth
• For induction models, verify you are using compatible cookware (ferrous metal-based pans with flat bottoms)
• Check that cookware is properly centered on the cooking zone
• Review the control panel settings and ensure no child lock or safety features are activated
• Ensure proper ventilation around the cooktop to prevent heat-related sensor issues
