Cause

Wiring is open or reversal phase (FDCA 301~601 type) Inverter primary side current is abnormal. (FDCVA151~251 type) Abnormal current cut of compressor (FDCA 301~601 type) 52C secondary side L3-phase wiring is open. (FDCA 301~601 type)

Outdoor heat exchanger temperature is high or outdoor heat exchanger thermistor is faulty.

Discharge temperature abnormality.

Outdoor unit heat exchanger thermistor failure

Outdoor air temperature thermistor failure Discharge pipe thermistor failure 63H1 operation (FDCA 301~601 type) Current (Abnormalities in a compressor over current) Inverter Over-voltage Trouble. (FDCVA 151~251 type) DC fan motor abnormal. (FDCVA 151~251 type) 52C abnormal. (FDCA 301~601 type)

Power transistor thermistor is faulty or disconnection or connector connections are poor. (FDCVA 151~251 type)

Insufficient refrigerant.

Compressor startup error (FDCVA 151~251 type)

Compressor loader position detection error. (FDCVA 151~251 type)

Note (1) The green LED in the outdoor unit is used in the FDCA301 ~ 601 models only.
