Supposed
Causes
!
Compressor overload
!
Compressor coil disconnected
!
Defect of outdoor unit PC board (A2P)
Troubleshooting
(V3184)
Be sure to turn off power switch before connect or disconnect connector,
or parts damage may be occurred.
Output current check
Caution
Inverter
output voltage
check Inverter output
voltage is not balanced
(Normal if within ±5V).
Must be measured when
frequency is stable.
Compressor overload
Inspection of the compressor and
refrigerant system is required.
Compressor inspection
Inspect according to the diagnosis
procedure for odd noises, vibration
and operating status of the
compressor.
Replace the inverter PC board
assy (A2P).
Reset and restart.
The
secondary current
of the inverter is higher than
13.1A, 260 sec. for each
phase.
Replace the compressor.
Compressor
inspection The
compressor's coil is
disconnected.
Disconnect the the connection
between the compressor and
inverter. Make the power
transistor check mode setting
