Freezer making loud humming or buzzing noise from rear

Safety first: Unplug the freezer before reaching behind or under it. Moving parts can cause injury.

• Locate noise source: Pull the freezer away from the wall and listen carefully to identify whether the noise comes from the compressor or fan.
• Inspect condenser fan: Remove the rear lower panel. Clear any debris contacting the fan blade. Ensure the blade is tight on the motor shaft.
• Check vibration points: Look for copper refrigerant lines touching the cabinet. Gently bend them away and insert foam or rubber spacers to prevent contact.
• Compressor mounts: Inspect rubber grommets under the compressor. If deteriorated, have them replaced to reduce vibration.
• Replace noisy fan: If the fan motor is excessively loud or rough, replace the condenser fan motor.
