Display shows E3 and the ambient temperature reading is incorrect or the unit behaves erratically in warm or cold rooms.

Safety: Unplug the wine cooler before accessing the toe-kick or control panel areas.

How to troubleshoot:

• Locate the ambient sensor: On many BODEGA43 models, the ambient NTC is positioned near the front ventilation grille or behind the front frame to sense room temperature.
• Visual inspection: Remove the lower front grille (toe-kick) and look for a small probe or sensor head on a thin cable. Ensure it is not hanging loose or touching hot components.
• Check wiring and connector: Trace the sensor cable back to the main control board or display PCB. Confirm the plug is fully seated and wires are not pinched by the cabinet or leveling feet.
• Measure resistance: With the unit unplugged, disconnect the sensor and measure resistance. Compare to expected NTC values (commonly 5–10 kΩ at 20–25°C). Replace if open or shorted.
• Reposition sensor: If the sensor is intact but reading incorrectly, ensure it is mounted where it can sense room air, not directly against the condenser or compressor.
• Replace if needed: Install a new ambient temperature sensor (NTC) compatible with BODEGA43 if readings are out of range.

After repair: Restore power, clear the error by power cycling, and verify that the E3 code does not return and that the unit responds correctly to room temperature changes.
