Oven makes loud popping, banging, or metallic noises during heating or cooling.

Safety first: Allow the oven to cool and turn off power before tightening any screws.

Steps:

• Identify source: Listen carefully to locate whether the noise comes from the oven cavity, back panel, or under the cooktop.
• Tighten hardware: Check and tighten screws on the back panel, side panels, and oven liner flanges.
• Inspect elements: Look for elements that are touching the oven liner or warped. Reposition or replace elements that contact the liner.
• Normal expansion: Some mild popping from metal expansion is normal, but very loud or new noises after a repair may indicate a loose part.
