Oven makes loud banging, rattling, or scraping noises when the convection fan is running.

Safety first: Turn off power and allow the oven to cool before removing the fan cover.

• 1. Remove fan cover: Unscrew and remove the fan cover inside the cavity. Inspect for loose screws or distortion.
• 2. Check for debris: Remove any food particles, screws, or foil pieces around the fan blade.
• 3. Tighten fan nut: Gently hold the fan blade and tighten the central nut (if fitted) to secure the blade to the motor shaft.
• 4. Spin test: Rotate the fan by hand. If it feels rough or wobbly, the motor bearings may be worn and the motor should be replaced.

Do not operate the oven with a loose or scraping fan, as this can damage the motor and fan housing.
