Refrigerator making loud buzzing, humming, or rattling noises during operation.

Safety first: Unplug the refrigerator before touching fans or internal components.

• Level the refrigerator: Use a level and adjust front feet so the unit is stable and does not rock.
• Check rear compartment: Remove rear panel and inspect condenser fan for debris or bent blades. Clean and straighten as needed.
• Secure tubing: Gently bend or clip refrigerant lines away from cabinet walls to prevent rattling.
• Inspect evaporator fan: If noise comes from the freezer, remove the back panel and check for ice hitting the fan. Defrost and correct any defrost issues.
