Display shows E0 and the wine cooler is not cooling properly or at all.

Safety first: Unplug the Lanbo wine cooler from the wall outlet before removing any panels or touching internal wiring.

This code typically indicates a problem with the internal cabinet temperature sensor (NTC) that tells the control board how cold the compartment is.

• 1. Power reset: Unplug the unit for 5 minutes, then plug it back in. If E0 returns after a few minutes, continue with checks.
• 2. Inspect sensor connection:
  • Locate the cabinet temperature sensor (usually behind the rear interior liner or clipped to the evaporator cover inside the compartment).
  • Remove the interior shelves and the rear plastic cover (if present).
  • Check the small two‑wire sensor harness for loose, corroded, or broken connectors.
• 3. Check sensor resistance (for advanced DIYers):
  • With the unit unplugged, disconnect the sensor from the harness.
  • Use a multimeter set to ohms and measure resistance across the sensor leads.
  • At room temperature (around 77°F / 25°C), most NTC sensors should read roughly 5k–10kΩ. A reading of 0Ω (short) or OL (open) indicates a bad sensor.
• 4. Replace the sensor if defective:
  • Order a compatible Lanbo cabinet temperature sensor (NTC) for your exact model.
  • Route the new sensor along the same path as the old one, avoiding sharp bends or pinching points.
  • Reconnect to the control board harness firmly.
• 5. If sensor tests good:
  • Inspect the wiring from the sensor to the main control board for cuts, pinches, or burn marks.
  • If wiring is intact and E0 persists, the main control board sensor circuit may be faulty and should be replaced by a qualified technician.
