Indesit oven emits a buzzing or humming noise from the control area when heating.

Safety warning: Disconnect power before accessing the control panel.

• 1. Identify source: Carefully listen to locate the buzzing area (control panel vs rear) during operation (qualified person only).
• 2. Tighten fixings: With power off, tighten screws securing the control board, transformer, and any relays that have mounting brackets.
• 3. Inspect relays: If a relay is excessively noisy and shows signs of overheating, consider replacing the control board.
• 4. Monitor: Mild humming can be normal. If noise is accompanied by malfunction or burning smell, stop using the oven and seek service.
