Freezer emits a high-pitched squealing or chirping noise, especially when the door is closed.

Safety: Unplug the freezer before accessing the fan.

Steps:

• Access fan: Remove shelves and the rear interior panel to expose the evaporator fan.
• Inspect blades: Remove any ice or debris. Ensure the blade is centered and not rubbing the shroud.
• Spin test: Rotate the fan by hand. If it feels rough or squeals, replace the fan motor assembly.
• Reassemble: Refit the panel, restore power, and verify quiet operation.
