Q: What to do after getting these error codes:
A:

E1 (plastic sensor) /E3 (copper sensor)

  • test resistance value (std: 5k? at 25�C) of sensor � if abnormal, replace with new one
  • check cable connection with PCB

E2

  • Signal cable between indoor and outdoor not connected due to unprofessionalism
  • Outdoor copper sensor broken, resistance infinite � check cable, socket and sensor.

E4

  • Check wire connection of indoor motor then restart appliance
  • If E4 still display, replace PCB.
  • Lastly, check the PG motor of indoor unit.
