Refrigerator making loud buzzing, humming, or rattling noises.

Safety first: Unplug the refrigerator before touching any moving parts or fans.

Steps to reduce noise:

• 1. Level the refrigerator: Adjust front leveling legs so the unit is stable and slightly tilted back. This can reduce cabinet vibrations.
• 2. Inspect rear compartment: Remove the rear cover and check the condenser fan for debris or bent blades. Clean and straighten as needed.
• 3. Check evaporator fan: If noise comes from inside the freezer, remove the rear interior panel and listen to the evaporator fan motor. Replace if noisy or wobbling.
• 4. Tighten components: Ensure the compressor mounting bolts, fan shrouds, and any loose panels are secure.
