Wine cooler emits a high-pitched squealing or chirping noise

Safety: Unplug the unit before working near fans.

• Determine which fan: Open the door and listen; if the noise is louder inside, suspect the evaporator fan. If louder at the back, suspect the condenser fan.
• Inspect fan blades: Check for warped or cracked blades rubbing against housings. Replace damaged blades if they are separate from the motor.
• Replace noisy fan motor: Remove mounting screws, disconnect wiring, and install a new OEM fan motor (evaporator or condenser as needed).
• Reassemble and test: Restore power and confirm the noise is gone.
