Cabinet temperature sensor out of calibration, Sensor not in correct location, Stuck compressor relay on main control board, Control board logic fault

How to Fix / Troubleshooting

Safety: Disconnect power before accessing sensors or the control board.

  • Verify setpoint: Ensure the temperature is not set too low for wine storage.
  • Check with thermometer: Place an accurate thermometer inside to confirm actual temperature versus display.
  • Inspect sensor placement: Make sure the cabinet sensor is not touching the evaporator or a cold wall; reposition if necessary.
  • Replace sensor: If readings are inaccurate, replace the cabinet NTC sensor with a TYLZA-compatible part.
  • If compressor never cycles off: The main control board relay may be stuck. Replace the main control board.
