Possible Causes

Thermostat or sensor miscalibration, Control board stuck in continuous cooling, Ambient temperature very low, Door gasket leaking causing overcooling near sensor

How to Fix / Troubleshooting

Safety first: Unplug the unit before accessing sensors or the control board.

  • Check setpoint: Verify that the set temperature is not set too low. Adjust to the recommended wine storage temperature (typically 41–64°F / 5–18°C depending on zone).
  • Ambient conditions: If the cooler is installed in a very cold room (e.g., unheated garage), the unit may overcool. Move it to a location within the manufacturer's specified ambient range.
  • Inspect sensors: If L1 persists, inspect the compartment temperature sensor for proper placement and damage as in E1/E2 procedures.
  • Control reset: Unplug the unit for 15 minutes to reset the control board. If the unit still overcools, the control board or sensor may need replacement.
