Freezer makes loud humming or buzzing noise from the back, especially when compressor runs.

Safety first: Unplug the freezer before adjusting components at the rear. Beware of hot compressor surfaces.

• 1. Level the appliance: Ensure the freezer is level front-to-back and side-to-side using the adjustable feet. An unlevel cabinet can increase vibration.
• 2. Check compressor mounts: Inspect the rubber grommets under the compressor. Replace any that are cracked or missing to reduce vibration transfer.
• 3. Secure tubing: Gently move condenser tubes away from the cabinet or each other if they are touching and rattling. Use approved clips or foam spacers.
• 4. Inspect condenser fan: Spin the fan by hand and ensure blades do not contact the shroud. Adjust or replace the fan if damaged.
• 5. Tighten panels: Tighten screws on the rear cover and base plate to eliminate rattles.
