Possible Causes
• Temperature sensor failure or malfunction

• Damaged or loose wiring connections to the temperature sensor
• Control board sensor circuit failure
• Blocked ventilation preventing proper heat dissipation
• Cookware left unattended causing extreme temperature buildup

✅
Safety Checks You Can Do
• Power cycle the cooktop: Turn off the main power switch or unplug for 60 seconds, then restore power
• Ensure proper ventilation: Check that all vents and ventilation areas around the cooktop are clear and unobstructed
• Verify cookware compatibility: Use only ferromagnetic cookware (for induction models) or flat-bottomed cookware (for electric models)
• Clean the cooking surface: Wipe down the cooktop with a damp cloth to remove food debris, spills, or buildup
• Check for foreign objects: Remove any items, cookware, or materials blocking heat sensors or ventilation
• Allow cooling time: If cooktop was in use, turn off and wait 30 minutes for the appliance to cool completely
• Inspect power connections: Ensure the cooktop is properly plugged in and the outlet is functioning (test with another appliance)
• Verify even cookware placement: Ensure pots and pans are properly centered on burners with full contact
