Display shows Lo and the set temperature cannot be adjusted lower than a certain point.

Lo on many Lanbo wine coolers simply indicates that you have reached the lowest allowable set temperature.

• 1. Try increasing setpoint:
  • Press the up arrow to raise the set temperature and confirm that the display changes from Lo to a numeric value.
• 2. Check buttons:
  • If Lo is flashing or controls are unresponsive, inspect the control panel for stuck or damaged buttons.
• 3. Power reset:
  • Unplug the unit for 5 minutes and plug it back in to reset the UI.
• 4. If Lo remains and temperature cannot be adjusted:
  • The display control board may be faulty and require replacement.
