Display shows E2 and the compressor may not start or may run continuously.

Unplug the wine cooler before servicing.

E2 generally indicates a fault with the ambient (room) temperature sensor used by some Lanbo models to adjust cooling performance.

• 1. Locate the ambient sensor:
  • It is often near the front grille, air intake, or behind the control panel.
  • Consult your model's diagram if available.
• 2. Visual inspection:
  • Check that the sensor is not dangling, crushed, or touching hot components.
  • Ensure the sensor tip is exposed to room air, not buried in insulation.
• 3. Check wiring and connector:
  • Look for loose plugs at the control board.
  • Inspect for cuts or abrasions along the harness.
• 4. Test sensor:
  • Disconnect the sensor and measure resistance at room temperature.
  • Compare to other NTC sensors in the unit if they share the same spec.
• 5. Replace if defective:
  • Install a new Lanbo ambient temperature sensor and route wiring away from moving parts and hot surfaces.
• 6. If E2 persists with a good sensor:
  • The main control board may be defective and should be evaluated or replaced by a professional.
