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

Safety: Unplug the freezer before adjusting internal components or touching moving parts.

Steps:

• 1. Level the appliance: Use a spirit level and adjust the front feet so the freezer is stable and does not rock.
• 2. Check rear components: Remove the rear cover and ensure the compressor mounting bolts are snug but not overtightened. Insert rubber pads if necessary.
• 3. Fan inspection: Check condenser and evaporator fans for debris or bent blades. Straighten or replace the fan blade or motor if damaged.
• 4. Refrigerant lines: Gently bend any copper lines that are touching and vibrating against the cabinet, taking care not to kink or crack them.
