Freezer making high-pitched squealing or chirping noise intermittently.

Safety: Disconnect power before touching any moving parts.

• Determine location: Open the door to see if the noise changes (evaporator fan) or listen at the rear (condenser fan).
• Inspect suspect fan: Access the evaporator or condenser fan as appropriate and spin the blade by hand. Squealing or roughness indicates bearing wear.
• Replace motor: Remove mounting screws, transfer the blade, and install a new fan motor of the correct type (evaporator or condenser).
