Symptoms
• Cooktop will not heat or ignite burners
• Touch controls are unresponsive or intermittently responsive
• One or more burner zones fail to activate
• Error code E5 displays on the control panel or digital display
• Cooktop may beep repeatedly or emit warning sounds
• All burners or zones affected simultaneously
• Cooktop powers on but no heating response to user input
Possible Causes
• Loose or corroded electrical connections at the 240V (electric/induction) or 120V (gas control) power supply
• Faulty touch control panel or membrane switch failure
• Defective temperature sensor or heating element circuit
• Control board malfunction or internal electronics failure
• Damaged cooktop glass on smoothtop or induction models affecting sensor operation
• Poor ground connection or electrical fault in the cooktop circuit
• 60Hz power supply interruption or voltage fluctuation
• Wet or moisture-damaged touch controls on the cooktop surface
Safety Checks You Can Do
• Ensure the cooktop is powered off and allow it to cool completely before inspection
• Check your home circuit breaker panel and verify the dedicated 240V circuit (electric/induction models) or 120V circuit (gas control models) is in the ON position and has not tripped
• Inspect the cooktop's power cord and plug connection at the wall outlet for loose, bent, or corroded contacts
• Examine the entire cooktop surface for visible cracks, chips, or damage in the glass on smoothtop or induction models
• Check that all burner caps and grates are seated properly and not obstructing heating element access on gas models
• Wipe the touch control panel and surrounding area with a dry cloth to remove any water, moisture, or condensation
• Verify the touch controls are not in a locked mode by checking for a lock indicator light or attempting the unlock gesture per your user manual
• Perform a hard reset by switching off the circuit breaker supplying power to the cooktop for 60 seconds, then switch it back ON
• Allow the cooktop 2-3 minutes to reinitialize and check if the error code clears
• If error persists after reset, avoid using the cooktop and consult a qualified technician for internal diagnostics
Safety First
