  7. System Overload or Overheating:
    • Cause: Overloading the aircon by setting the temperature too low or using other appliances on the same circuit can cause the system to overheat.
    • Solution: Avoid overloading the system by setting reasonable temperature levels and not using excessive appliances on the same circuit. Allow the system to cool down before restarting it.
