Refrigerator making loud buzzing, humming, or rattling noises.

Safety: Unplug the refrigerator before touching fans or moving the unit.

• Level the unit: Adjust front leveling legs so the refrigerator is stable and slightly tilted back.
• Check rear components: Remove the rear panel and inspect the condenser fan for debris or loose mounting.
• Inspect interior: Rearrange items so they are not touching the back wall or each other in a way that can vibrate.
• Check for ice on fan: If noise comes from the freezer and changes when the door is opened, the evaporator fan may be hitting ice. Defrost the unit fully if heavy frost is present.

Persistent loud fan or compressor noises may indicate failing motors or compressor and should be evaluated by a technician.
