Freezer is cold but makes loud humming, buzzing, or rattling noises during operation.

Safety: Unplug the freezer before touching moving parts or metal tubing.

• Identify noise source: Listen at the back (compressor/condenser fan) and inside the freezer (evaporator fan) to locate the noise.
• Check leveling: Ensure the freezer is level front-to-back and side-to-side using the adjustable front legs. An unlevel unit can cause vibrations.
• Inspect condenser fan area: Remove the rear panel and check that the fan shroud and motor are firmly mounted. Tighten any loose screws.
• Secure tubing: Look for copper lines touching each other or the cabinet. Gently bend them apart and insert foam or rubber spacers to prevent rattling.
• Check evaporator fan: Inside the freezer, remove the rear interior panel and inspect the fan. If the motor is noisy or the blade is damaged, replace the Samsung evaporator fan motor and/or blade.
• Compressor noise: Some compressor hum is normal. If the compressor is excessively loud or knocking, consult a technician; compressor replacement may be required.
