Oven makes a loud banging or popping noise when heating up or cooling down.

Safety first: Turn off power before tightening any internal screws.

• Check installation: Verify that the oven is securely fixed to the cabinet using the mounting screws provided by Blomberg.
• Inspect internal panels: Remove shelves and check that side and rear liners are properly seated and screws are tight.
• Examine elements: Look for elements that are touching the cavity walls or supports. Gently adjust to ensure clearance.
• Secure loose parts: Tighten any loose brackets, screws, or trim pieces that may flex during heating.
