Possible Causes
Incorrect temperature setting, failed thermistor reading too warm, control board stuck in cooling mode, compressor relay welded closed
How to Fix / Troubleshooting
Safety: Unplug the unit before removing panels.
- Verify settings: Check that the set temperature is appropriate for wine storage (typically 45–65°F depending on zone). Adjust if set too low.
- Power reset: Unplug for 5 minutes, then restore power to clear any temporary control glitch.
- Check thermistor: If the unit continues to overcool, test the cabinet thermistor as described for sensor errors. Replace if out of spec.
- Control board: If the thermistor is good but the compressor runs almost constantly, the main control board relay may be stuck. Replace the control board.
Monitor temperature after repair to ensure it stabilizes at the setpoint.
