Display shows E3 and the ambient temperature reading is incorrect or not displayed.

Safety first: Unplug the wine cooler before removing the top or front trim panels.

Some EuroCave models use an ambient sensor to adjust performance based on room temperature. E3 indicates this sensor is not being read correctly.

• Step 1 – Check installation environment: Ensure the cabinet is not installed in direct sunlight, next to an oven, or in a confined space without ventilation. Overheating can cause sensor errors.
• Step 2 – Locate the ambient sensor: It is often located behind the front grille, near the toe-kick, or behind the top control panel. Look for a small probe or sensor housing exposed to room air.
• Step 3 – Inspect wiring: Check for pinched, cut, or chewed wires (rodent damage). Verify connectors are firmly seated on the display/control PCB.
• Step 4 – Test/replace sensor: With power disconnected, measure resistance of the ambient NTC and compare to spec. If open, shorted, or far out of range, replace with the correct EuroCave ambient sensor.
• Step 5 – Reset and test: Reassemble, restore power, and confirm that E3 clears and that the ambient temperature (if displayed) is reasonable.

When to seek service: If the sensor and wiring are good, the display PCB or main control board may be defective.
