Freezer is noisy, with loud humming, rattling, or knocking sounds during operation.

Safety: Unplug the freezer before adjusting components or removing panels.

• 1. Identify noise source: Listen carefully to determine if the noise comes from the rear (compressor/condenser) or inside (evaporator fan).
• 2. Rear noise checks: Remove the rear lower panel. Ensure the compressor mounting grommets are intact and that the compressor is not touching the cabinet directly. Tighten loose brackets.
• 3. Secure tubing: Look for copper or aluminum pipes touching each other or the cabinet. Insert foam or rubber spacers to prevent vibration contact.
• 4. Internal noise checks: Remove drawers and the inner rear panel. Inspect the evaporator fan for ice buildup or foreign objects. Defrost any ice and clear obstructions.
• 5. Replace noisy fan: If the fan motor squeals or grinds when spinning, replace the evaporator fan motor with a Siemens-compatible unit.
• 6. Level the appliance: Adjust the front feet so the freezer is level and stable; rocking can amplify vibrations.

Note: Some compressor noise is normal, but sudden changes or metallic knocking should be investigated promptly.
