Display shows E1 and the wine cooler runs erratically or does not maintain set temperature.

Safety warning: Disconnect power before removing interior panels or touching wiring.

E1 usually points to a problem with the evaporator temperature sensor that monitors coil temperature for defrost and cooling control.

• 1. Access the evaporator area:
  • Remove shelves and the rear interior panel inside the affected zone.
  • Locate the small sensor clipped or taped to the evaporator coil.
• 2. Check sensor placement:
  • Ensure the sensor is firmly attached to the evaporator coil and not hanging loose.
  • If it has fallen off, reattach it using aluminum tape or the original clip.
• 3. Inspect wiring:
  • Look for cracked insulation, pinched wires, or corroded connectors between the sensor and the control board.
• 4. Test sensor resistance:
  • Unplug the unit and disconnect the sensor.
  • Measure resistance with a multimeter; compare to the cabinet sensor if they are the same type.
  • Open or shorted readings indicate a bad sensor.
• 5. Replace the evaporator sensor if faulty:
  • Install a new Lanbo evaporator temperature sensor (NTC) and secure it tightly to the coil.
• 6. If sensor and wiring are good:
  • The main control board may not be reading the sensor correctly and may need replacement by a technician.
