Freezer vibrates excessively or makes thumping noises

Safety first: Avoid tipping the freezer excessively; keep it upright to protect the sealed system.

• Level the unit: Use a bubble level on top of the freezer. Adjust front leveling legs so the unit is level side-to-side and slightly tilted back.
• Check clearances: Ensure there is at least the manufacturer-recommended clearance from walls and cabinets so the cabinet does not rub.
• Stabilize legs: Tighten lock nuts on leveling legs if present. Place vibration-absorbing pads under legs if the floor is uneven.
• Secure loose panels: Tighten any loose screws on the rear access panel or toe grille that may rattle.
