High-pitched squealing or chirping noise from inside the cabinet.

Safety: Unplug the cooler before accessing the evaporator fan.

• 1. Access the fan: Remove interior shelves and the rear inner panel to expose the evaporator fan.
• 2. Inspect for ice or debris: Look for frost buildup or foreign objects contacting the fan blade. Defrost and clean as needed.
• 3. Spin the fan by hand: If it feels rough or makes noise, the motor bearings are likely worn. Replace the evaporator fan motor.
• 4. Reassemble and test: After replacement, restore power and confirm quiet operation.
