Indicator
Wired remote
controller
Error code E: 84
Detective actuator Outdoor unit main PCB
When input current sensor has detected 0 A, while
inverter compressor is operating at higher than 50 rps,
after 1 minute upon starting the compressor. (Except
during the defrost operation)
Forecast of cause
Defective connection of electric components
External cause
Main PCB failure
Check point 1. Reset power supply and operate
If no, go to "Check point 1-2".
Does error indication show again?
↓
Check point 2. Check connections of outdoor
unit electrical components
Upon correcting the removed connector or mis-
wiring, reset the power.
• Check if the terminal connection is loose.
• Check if connector is removed.
• Check erroneous connection.
• Check if cable is open.
↓
Check point 3. Replace main PCB
If Check point 1, 2 do not improve the symptom,
change main PCB.

End
Check point 1-2. Check external cause at Indoor and Outdoor (Voltage drop or Noise)
• Instant drop: Check if there is a large load electric apparatus in the same circuit.
• Momentary power failure: Check if there is a defective contact or leak current in the power sup-
ply circuit.
• Noise: Check if there is any equipment causing harmonic wave near electric line. (Neon bulb or
electric equipment that may cause harmonic wave)
Check the complete insulation of grounding.
