Likely causes
- CommonThermostat set too lowA simple setting mistake is the most common cause, especially after a recent adjustment.
- CommonFaulty temperature sensorA sensor reading incorrectly can cause the unit to keep cooling past the intended setpoint.
- PossibleDoor seal letting in warm air, causing overcompensationThe unit may run harder and colder trying to compensate for a leaky seal.
- PossibleControl board malfunctionElectronic controls can fail and run the compressor continuously.
What to do
- Check and adjust the thermostat to the recommended range for your wine type (typically 45–65°F depending on red or white).
- Wait 24 hours after any adjustment before making another change, since these units respond slowly.
- Inspect the door seal for gaps by closing it on a piece of paper and checking if it pulls out easily.
- Clean the door gasket with mild soap and water, since grime can prevent a full seal.
- Unplug and re-plug the unit to reset the control board if adjusting the thermostat doesn't help.
- Move any bottles that were closest to a vent, since that area is often the coldest spot.
Tools and parts
