Indesit oven makes loud rattling or grinding noises when the fan is running.

Safety first: Disconnect mains power before accessing the fan.

• 1. Remove internal fan cover: Take out shelves and unscrew the rear cover to expose the fan.
• 2. Check for debris: Remove any loose screws, foil, or food debris around the fan.
• 3. Inspect fan blade: Ensure the blade is tight on the shaft and not bent. Tighten the centre nut if loose. Replace the blade if damaged.
• 4. Assess motor bearings: Spin the fan by hand. If it feels rough, wobbles, or squeals, replace the convection fan motor assembly.
