| Error Code | Meaning | Common Cause & Solution | | :--- | :--- | :--- | | | High Temperature Alarm | The measured temperature is above the high setpoint. Check if the sensor is faulty or the cooling system is failing. | | LLL | Low Temperature Alarm | The measured temperature is below the low setpoint, or the unit has iced up. Check for a faulty sensor or possible ice buildup. | | Flashing "HHH" | Sensor Failure | The controller cannot read the sensor signal. The internal temperature is too high, or the cabinet sensor is faulty. | | Flashing "LLL" | Sensor Failure or Icing | The internal temperature is too low, the unit has iced up, or the cabinet sensor is faulty. | | E1 (on some units) | Cabinet Sensor Failure | The primary temperature sensor inside the cabinet is not working. | | E2 (on some units) | Evaporator Sensor Failure | The sensor on the evaporator coil (used for defrost) has failed. |
