1. 1

   Open the freezer door and listen if the noise stops; this confirms it is the fan causing the noise.

2. 2

   Unplug the Refrigerator for at least 24 hours to allow any ice buildup on the coils to melt completely.

3. 3

   Access the back panel of the freezer to inspect the coils for heavy frost buildup after defrosting.

4. 4

   If ice is present after defrosting, a component like the heater, thermostat, or PCB may need professional diagnosis.
