Cabinet interior is too cold in spots and too warm in others; uneven temperature distribution.

Safety: Unplug the cooler before accessing the internal fan.

• Rearrange bottles: Avoid stacking bottles tightly against the back wall or over air vents. Leave space for air to circulate.
• Check internal fan: Remove shelves and the interior rear panel to access the circulation fan. Ensure it spins freely and runs when the unit is cooling.
• Clean fan and vents: Remove dust and debris from the fan blades and air channels.
• Replace fan if failed: Install a new Aobosi-compatible internal circulation fan if the motor is not operating.
