Display shows L1 or LO; interior temperature is much colder than setpoint; bottles may be frosting or freezing.

Safety: Unplug the wine cooler before accessing the control board or sensors.

Steps to address L1/LO:

• Check temperature setting: Confirm that the set temperature is appropriate for wine storage and has not been accidentally set too low.
• Verify sensor readings: Compare the displayed temperature to an accurate thermometer placed inside the cooler. If the display is much higher than actual, the sensor may be faulty.
• Inspect cabinet thermistor: Access the interior sensor as described for E1. Check for proper mounting and test resistance with a multimeter. Replace the cabinet temperature sensor if readings are out of range.
• Check control board: If the sensor is good but the compressor runs almost constantly and the unit overcools, the cooling relay on the main control board may be stuck closed.
• Replace control board if needed: Access and replace the main PCB with the correct Kenmore part if the relay is suspected to be stuck or burned.
• Monitor operation: After repairs, allow the unit to stabilize for several hours and confirm that the temperature cycles around the setpoint without freezing bottles.
