Freezer making loud buzzing or humming noise from compressor area.

Safety first: Unplug the freezer before adjusting components near the compressor.

• Check leveling: Ensure the freezer is level front-to-back and side-to-side. Adjust leveling feet as needed.
• Inspect fan: Remove rear panel and check if the condenser fan blade is rubbing against its shroud or wiring. Reposition or secure components to clear the blade.
• Secure tubing: Look for refrigerant lines touching the cabinet. Add foam sleeves or clips to prevent vibration noise.
• Compressor mounts: Verify that rubber grommets under the compressor are intact. Replace if hardened or missing.
• Persistent loud hum: If the compressor itself is excessively loud and hot, it may be failing and should be evaluated by a professional technician.
