Loud humming, rattling, or vibrating noise during operation; noise may change when door is opened.

Safety first: Unplug the unit before tightening any internal components. Avoid contact with moving fan blades.

Steps:

• 1. Level the appliance: Use a spirit level and adjust the front feet until the cabinet is stable and does not rock.
• 2. Reposition bottles and shelves: Ensure bottles are not touching the back wall or each other tightly; add felt pads or reposition shelves if needed.
• 3. Check rear components: Remove rear cover and verify that the compressor is securely mounted on its rubber grommets and not touching the cabinet.
• 4. Inspect fans: Check evaporator and condenser fans for loose blades or obstructions. Tighten mounting screws.
• 5. Test noise: Restore power and listen. If a fan motor is still excessively noisy, replace it.
