Oven makes loud banging or popping noises when heating or cooling

Safety: Disconnect power and allow the oven to cool before tightening any screws.

• Identify source: Listen carefully during operation to locate whether the noise comes from the cavity walls, fan area, or door.
• Tighten screws: Remove internal panels (side rails, rear cover) and tighten all accessible screws and brackets.
• Check elements: Ensure heating elements are firmly clipped into their supports and not flexing excessively.
• Door components: Tighten door handle and glass retaining screws.
• Note: Some minor ticking from metal expansion is normal, but loud bangs indicate loose parts that should be secured.
