2-10. 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 425
V or lower than 80 V. For 14 model, when inverter
output DC voltage is higher than 415V 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 main PCB
If check point 1 to 2 do not improve the symptom, change main PCB.
