Range or cooktop makes a buzzing or humming noise during operation.

Safety first: Disconnect power before tightening panels or accessing internal components.

• Identify source: Listen carefully to locate the noise. Induction zones often make a soft buzzing that changes with power level and is normal.
• Check panels: Tighten any loose screws on side panels, back panels, or cooktop mounting brackets that may vibrate.
• Inspect fan: If the noise is from the cooling fan, check for debris or bent blades and clean as needed.
• Service if abnormal: Loud, harsh buzzing or arcing sounds may indicate a failing induction power module or transformer and should be inspected by a technician.
