  • Page 30: Troubleshooting

    10 Troubleshooting In general, possible trouble is classified in three kinds. One is called Starting Failure which is caused from an electrical defect, another is ineffective Air Conditioning caused by a defect in the refrigeration circuit and improper application, and the other is called the Structure Damage. Operation panel doesn't work.
  • Page 31 Display keeps showing "Ed". Check whether the evaporator frosts. Check whether the indoor air inlet is blocked. Check whether the indoor ambient temperature is too low. Check whether the indoor dust filter is too dirty. Check whether there is too much water on the chassis. Check the wiring of pipe temperature sensor.
  • Page 32 Compressor doesn’t work. Check whether the indoor temperature is lower than 15°C or larger than. Check the power supply. Check whether the voltage is too high or too low. Check the wiring. Check whether the compressor is under overload protection. Check whether the relay of compressor in PCB works normally (Start the unit, after 3mins, and set the unit with cool mode and 17°C (62°F).
  • Page 33 Cooling mode doesn't work or cooling not enough. Check the operation mode. Check the setting temperature. Check whether dust filter is too dirty. Start the unit with cool mode and check whether the temperature of compressor’s discharge pipe is smaller than 90°C. If no, recharge refrigerant. Replace the capillary.
  • Page 34 The compressor operates run-stop frequently. Check whether the airflow passage is blocked. Check whether the fan motor doesn’t work. Check whether capacitor of compressor work normally. Check whether the relay of compressor on PCB works normally. Replace the PCB. Check whether the capillary is blocked. Replace the capillary.
  • Page 35 Water drips from the unit. Check whether the ambient humidity is too high. Check whether the indoor outlet airflow foam is too wet, and louver drip. Check whether the unit is correctly installed. Check whether the air outlet foam install normally. Check whether the foam of evaporator base is damaged.
