Refrigerator making loud buzzing or rattling noises from the rear.

Safety: Unplug the appliance before touching moving parts or metalwork.

Steps:

• Access rear: Remove the rear lower panel to inspect the condenser area.
• Check fan: Look for debris in the fan blades and remove it. Ensure the fan shroud is secure.
• Secure pipes: If copper pipes are touching each other or the cabinet, gently reposition them and add foam or rubber spacers to prevent vibration.
• Tighten panels: Tighten any loose screws on the rear panel or compressor mounting.
• Test: Restore power and listen. If the compressor itself is excessively noisy, it may be failing and require professional evaluation.
