Refrigerator is noisy; loud humming, rattling, or buzzing sounds during operation.

Safety first: Unplug the refrigerator before touching moving parts or the compressor area.

Steps:

• 1. Level the appliance: Adjust the front leveling feet so the cabinet is stable and does not rock. Slight backward tilt helps doors close.
• 2. Check for external vibrations: Ensure the refrigerator is not touching walls or cabinets that can resonate.
• 3. Inspect fans: Remove interior panels to access the evaporator fan and the rear cover to access the condenser fan. Clear any ice or debris from blades and shrouds.
• 4. Test fan bearings: Spin the fan by hand; grinding or wobbling indicates a worn motor. Replace the fan motor assembly.
• 5. Secure tubing and components: Gently bend and clip refrigerant lines away from each other and from the cabinet to prevent rattling. Do not kink the tubes.
