Freezer is noisy; loud humming, buzzing, or rattling sounds during operation.

Safety: Unplug before adjusting internal components or fans.

Steps:

• Level the freezer: Use a spirit level and adjust the front leveling feet so the cabinet is stable and slightly tilted back.
• Check external vibrations: Ensure the freezer is not touching walls or cabinets that can resonate.
• Inspect fans: Access the evaporator fan (inside) and condenser fan (rear, if present). Remove any ice, debris, or wires contacting the blades. Replace worn or noisy fan motors.
• Secure tubing and compressor: Gently bend refrigerant lines away from each other or from cabinet surfaces if they are touching and vibrating. Tighten compressor mounting bolts if loose.
