High-pitched whistling or whooshing noise from inside the refrigerator.

Safety: Unplug the refrigerator before accessing interior panels.

Steps:

• 1. Check loading: Ensure food items are not pressed against rear walls or vents. Leave space for airflow.
• 2. Inspect fan area: Remove the interior panel covering the evaporator fan and check for loose foam ducts or panels. Secure with screws or clips.
• 3. Fan blade: Inspect the fan blade for cracks or warping. Replace the fan motor assembly if the blade is damaged.
• 4. Normal operation: Some airflow noise is normal, especially after door openings or warm food loading. Monitor if it diminishes after temperatures stabilize.
