2-26. E: 64. PFC circuit error (Outdoor unit)
Indicator Indoor unit
Operation indicator 6 time flash
Timer indicator 4 time flash
Economy indicator Continuous flash
Error code E: 64
Detective actuator Outdoor unit Main PCB
• When inverter input DC voltage is higher than 415
V (14 type) or 420 V (18 type) for over 3 seconds,
the compressor stops.
• If the same operation is repeated 5 times, the
compressor stops permanently.
Forecast of cause External cause
Connector connection failure
Main PCB failure
Check point 1. 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.

Check point 2. Check connection of Connector
• Check if connector is removed.
• Check erroneous connection.
• Check if cable is open.
→ Upon correcting the removed connector or mis-wiring, reset the power.

Check point 3. Replace the main PCB
If check point 1 to 2 do not improve the symptom, replace the main PCB.
