Troubleshooting

If you encounter issues with your LAE LCD-5S controller, refer to the following common problems and solutions:

• Display is Blank:
  • Check if the main refrigeration system is powered on.
  • Verify the flat cable connection is secure at both ends.
  • Ensure the power button on the LCD-5S is pressed (if applicable for standby).
• Incorrect Temperature Reading:
  • This display unit shows readings from the main system. Check the temperature sensor connected to the main refrigeration unit for proper placement and function.
  • Ensure no obstructions are affecting the sensor's ability to read ambient temperature accurately.
• Alarm Bell Symbol is On:
  • An alarm indicates a condition outside of normal operating parameters (e.g., high temperature, sensor error).
  • Consult the main refrigeration system's manual for specific alarm codes and their meanings.
  • Address the underlying issue causing the alarm.
• Buttons Not Responding:
  • Ensure the unit is not in a locked mode (if such a feature exists, refer to the main system manual).
