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

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

• Level the appliance: Use a spirit level and adjust the front feet so the Ariston freezer is stable and does not rock.
• Check for contact points: Ensure the cabinet is not touching walls or cabinets that can amplify vibration.
• Inspect fans: Remove covers and check that fan blades are not bent or rubbing against shrouds. Clear any ice or debris.
• Tighten mounts: Gently tighten any loose screws on compressor mounting brackets or internal panels.

When to call a technician: If the compressor itself is extremely loud or knocking, it may be failing and should be inspected by a professional.
