Refrigerator making loud buzzing or rattling noise from rear.

Safety First: Unplug the refrigerator before reaching behind or under it.

• 1. Access rear compartment: Remove the lower rear access panel to expose the compressor and condenser fan.
• 2. Inspect fan: Check for paper, dust, or debris in the fan blades. Clean thoroughly. Spin the fan by hand; if rough or noisy, replace the condenser fan motor.
• 3. Check compressor mounts: Ensure the compressor mounting springs or rubber grommets are intact. Replace missing or damaged mounts.
• 4. Secure tubing: If copper lines are touching each other or the cabinet, gently bend them apart and add foam sleeves or clips to prevent vibration.
