JennAir range or cooktop emits buzzing or humming noise when elements are on (no error code)

Safety: Turn off power before tightening panels.

• Identify source: Listen carefully to locate the noise. Some low-level humming from induction or radiant elements and relays is normal.
• Tighten panels: Check and tighten screws on back panels, side trims, and control panel to reduce vibration.
• Check fan mounts: Ensure cooling or convection fans are securely mounted and not contacting other parts.
• Service if abnormal: If the noise is loud, new, or accompanied by burning smell or malfunction, have a technician inspect the control board and transformers.
